README
|
||||
======
|
||||
|
||||
This README discusses issues unique to NuttX configurations for the
|
||||
Arduino M0. I used a compatible board called Wemos SAMD21 M0 board,
|
||||
but there are other equivalent boards, like the RobotDyn SAMD21 M0.
|
||||
|
||||
Unfortunately because the Arduino.cc vs Arduino.org conflict in the past,
|
||||
we have three types of boards: Arduino Zero, Arduino M0 and Arduino M0 Pro.
|
||||
|
||||
The Wemos SAMD21 M0 is compatible with Arduino M0, but not exactly a clone.
|
||||
|
||||
You have two options to program it: using the SWD (EDBG) connector that
|
||||
comes in the board or the Arduino M0 bootloader that comes flashed on it.
|
||||
Currently only SWD programming is supported. Bootloader skip area should be
|
||||
implemented to avoid overwriting the bootloader area.
|
||||
|
||||
The board uses the ATSAMD21G18A MCU and can work over the Native USB Port.

STATUS/ISSUES
|
||||
=============
|
||||
|
||||
Because the Arduino M0 doesn't have a 12MHz crystal, it uses the internal
|
||||
RC oscillator.
|
||||
|
||||
LEDs
|
||||
====
|
||||
|
||||
There is one yellow LED available on the Arduino M0 and it can be turned
|
||||
on and off. The LED can be activated by driving the connected
|
||||
PA17 I/O line to high level.
|
||||
|
||||
When CONFIG_ARCH_LEDS is defined in the NuttX configuration, NuttX will
|
||||
control the LED as follows:
|
||||
|
||||
SYMBOL Meaning LED0
|
||||
------------------- ----------------------- ------
|
||||
LED_STARTED NuttX has been started OFF
|
||||
LED_HEAPALLOCATE Heap has been allocated OFF
|
||||
LED_IRQSENABLED Interrupts enabled OFF
|
||||
LED_STACKCREATED Idle stack created ON
|
||||
LED_INIRQ In an interrupt N/C
|
||||
LED_SIGNAL In a signal handler N/C
|
||||
LED_ASSERTION An assertion failed N/C
|
||||
LED_PANIC The system has crashed FLASH
|
||||
|
||||
Thus is LED is statically on, NuttX has successfully booted and is,
|
||||
apparently, running normally. If LED is flashing at approximately
|
||||
2Hz, then a fatal error has been detected and the system has halted.
|
||||
|
||||
Serial Consoles
|
||||
===============
|
||||
|
||||
SERCOM5
|
||||
------
|
||||
|
||||
SERCOM5 is available on pins PB22 (TXD) and PB23 (RXD). You will need to
|
||||
solder a two pins header to RXD and TXD labels, near to ICSP pin header.
|
||||
|
||||
PIN GPIO Function
|
||||
---- ---- ------------------
|
||||
37 PB22 SERCOM5 / USART RX
|
||||
38 PB23 SERCOM5 / USART TX
|
||||
|
||||
If you have a 3.3V USB/Serial adapter then this is the most convenient
|
||||
serial console to use (because you don't lose the console device each time
|
||||
you lose the USB connection). It is the default in all of these
|
||||
configurations. An option is to use the virtual COM port.
|
||||
|
||||
Native USB Port
|
||||
---------------
|
||||
|
||||
You can access the NSH shell directly using the USB connector. All you need
|
||||
to do is use the "usbnsh" board profile.
|
||||
|
||||
Configurations
|
||||
==============
|
||||
|
||||
Each Arduino M0 configuration is maintained in a sub-directory and
|
||||
can be selected as follow:
|
||||
|
||||
tools/configure.sh arduino-m0:<subdir>
|
||||
|
||||
Before building, make sure the PATH environment variable include the
|
||||
correct path to the directory than holds your toolchain binaries.
|
||||
|
||||
And then build NuttX by simply typing the following. At the conclusion of
|
||||
the make, the nuttx binary will reside in an ELF file called, simply, nuttx.
|
||||
|
||||
make
|
||||
|
||||
The <subdir> that is provided above as an argument to the tools/configure.sh
|
||||
must be is one of the following.
|
||||
|
||||
NOTE: These configurations use the mconf-based configuration tool. To
|
||||
change any of these configurations using that tool, you should:
|
||||
|
||||
a. Build and install the kconfig-mconf tool. See nuttx/README.txt
|
||||
see additional README.txt files in the NuttX tools repository.
|
||||
|
||||
b. Execute 'make menuconfig' in nuttx/ in order to start the
|
||||
reconfiguration process.
|
||||
|
||||
NOTES:
|
||||
|
||||
1. These configurations use the mconf-based configuration tool. To
|
||||
change any of these configurations using that tool, you should:
|
||||
|
||||
a. Build and install the kconfig-mconf tool. See nuttx/README.txt
|
||||
see additional README.txt files in the NuttX tools repository.
|
||||
|
||||
b. Execute 'make menuconfig' in nuttx/ in order to start the
|
||||
reconfiguration process.
|
||||
|
||||
Configuration sub-directories
|
||||
-----------------------------
|
||||
|
||||
nsh:
|
||||
This configuration directory will built the NuttShell. See NOTES above
|
||||
and below:
|
||||
|
||||
NOTES:
|
||||
|
||||
1. This configuration is set up to build on Windows using the Cygwin
|
||||
environment using the ARM EABI toolchain. This can be easily
|
||||
changed as described above under "Configurations."
|
||||
|
||||
2. By default, this configuration provides a serial console on SERCOM5
|
||||
at 115200 8N1 via RXD/TXD pads:
|
||||
|
||||
PIN EXT3 GPIO Function
|
||||
---- ---- ------------------
|
||||
37 PB22 SERCOM5 / USART RX
|
||||
38 PB23 SERCOM5 / USART TX
|
||||
|
||||
usbnsh:
|
||||
This configuration directory will build the NuttShell to work over USB.
|
||||
It uses the internal SAMD21 USB port working as CDC/ACM Serial/Modem.
|
||||
|
||||
Using the configuration you don't need to solder the header pins RXD/TXD
|
||||
to get access the NSH terminal.

*
|

* Input Parameters:

||||
* arg - The boardctl() argument is passed to the board_app_initialize()
|
||||
* implementation without modification. The argument has no
|
||||
* meaning to NuttX; the meaning of the argument is a contract
|
||||
* between the board-specific initialization logic and the
|
||||
* matching application logic. The value could be such things as a
|
||||
* mode enumeration value, a set of DIP switch switch settings, a
|
||||
* pointer to configuration data read from a file or serial FLASH,
|
||||
* or whatever you would like to do with it. Every implementation
|
||||
* should accept zero/NULL as a default configuration.
|
||||
*
|
||||
* Returned Value:
|
||||
* Zero (OK) is returned on success; a negated errno value is returned on
|
||||
* any failure to indicate the nature of the failure.

*

* To use this common SPI logic on your board:

* 1. Provide logic in sam_boardinitialize() to configure SPI chip select

* pins.
|
||||
* 2. Provide sam_spi[n]select() and sam_spi[n]status() functions in your

* board-specific logic. These functions will perform chip selection
|

* and status operations using GPIOs in the way your board is

* configured.
|
||||
* 2. If CONFIG_SPI_CMDDATA is defined in the NuttX configuration, provide
|
||||
* sam_spi[n]cmddata() functions in your board-specific logic. This
|
||||
* function will perform cmd/data selection operations using GPIOs in
|
||||
* the way your board is configured.
|
||||
* 3. Add a call to sam_spibus_initialize() in your low level application
|
||||
* initialization logic
|
||||
* 4. The handle returned by sam_spibus_initialize() may then be used to
|
||||
* bind the SPI driver to higher level logic (e.g., calling
|

* mmcsd_spislotinitialize(), for example, will bind the SPI driver to

|

* An alternative way to program the PIO chip select pins is as a normal

* GPIO output. In that case, the automatic control of the CS pins is

* Name: sam_spi[n]cmddata
|
||||
*
|
||||
* Description:
|
||||
* Some SPI devices require an additional control to determine if the SPI
|
||||
* data being sent is a command or is data. If CONFIG_SPI_CMDDATA then
|
||||
* this function will be called to different be command and data transfers.
|
||||
*
|
||||
* This is often needed, for example, by LCD drivers. Some LCD hardware
|
||||
* may be configured to use 9-bit data transfers with the 9th bit
|
||||
* indicating command or data. That same hardware may be configurable,
|
||||
* instead, to use 8-bit data but to require an additional, board-
|
||||
* specific GPIO control to distinguish command and data. This function
|
||||
* would be needed in that latter case.
|
||||
*
|
||||
* Input Parameters:
|
||||
* dev - SPI device info
|
||||
* devid - Identifies the (logical) device
|
||||
*
|
||||
* Returned Value:
|
||||
* Zero on success; a negated errno on failure.

README
|
||||
======
|
||||
|
||||
This README discusses issues unique to NuttX configurations for the
|
||||
Atmel SAMD20 Xplained Pro development board. This board features the
|
||||
ATSAMD20J18A MCU.
|
||||
|
||||
The SAMD20 Xplained Pro Starter Kit may be bundled with three modules:
|
||||
|
||||
1) I/O1 - An MMC/SD card slot, PWM LED control, ADC light sensor, USART
|
||||
loopback, TWI AT30TSE758 Temperature sensor.
|
||||
2) OLED1 - An OLED plus 3 additional switches and 3 additional LEDs
|
||||
3) PROTO1 - A prototyping board with logic on board (other than power-related
|
||||
logic).

STATUS/ISSUES
|
||||
=============
|
||||
|
||||
1. The FLASH wait states is set to 2 (see include/board.h). According to
|
||||
the data sheet, it should work at 1 but I sometimes see crashes when
|
||||
the wait states are set to one (about half of the time) (2014-2-18).
|
||||
|
||||
2. Garbage appears on the display sometimes after a reset (maybe 20% of
|
||||
the time) or after a power cycle (less after a power cycle). I don't
|
||||
understand the cause of this but most of this can be eliminated by
|
||||
simply holding the reset button longer and releasing it cleanly
|
||||
(then it fails maybe 5-10% of the time, maybe because of button
|
||||
chatter?) (2014-2-18).
|
||||
|
||||
- The garbage is not random: It is always the same.
|
||||
- This is not effected by BAUD rate. Curiously, the same garbage
|
||||
appears at different BAUD settings implying that this may not even
|
||||
be clock related???
|
||||
- The program seems to be running normally, just producing bad output.
|
||||
|
||||
3. SPI current hangs so not much progress has been made testing the I/O1
|
||||
module. The hang occurs because the SPI is waiting for SYNCBUSY to
|
||||
be cleared after enabling the SPI. This even does not happen and so
|
||||
causes the hang.
|
||||
|
||||
Another note: Enabling the SPI on SERCOM0 also seems to interfere
|
||||
with the USART output on SERCOM4. Both symptoms imply some clock-
|
||||
related issue.
|
||||
|
||||
The configuration suggests CONFIG_MMCSD_HAVE_CARDDETECT=y, but as of
|
||||
this writing, there is no support for EIC pin interrupts.
|
||||
|
||||
4. OLED1 module is untested. These instructions were just lifted from
|
||||
the SAM4L Xplained Pro README.txt file.
|
||||
|
||||
Modules
|
||||
=======
|
||||
|
||||
The SAMD20 Xplained Pro Starter Kit is bundled with four modules:
|
||||
|
||||
I/O1
|
||||
----
|
||||
The primary function of this module is to provide SD card support, but
|
||||
the full list of modules features include:
|
||||
|
||||
- microSD card connector (SPI interface)
|
||||
- PWM (LED control)
|
||||
- ADC (light sensor)
|
||||
- USART loopback
|
||||
- TWI AT30TSE758 Temperature sensor with EEPROM
|
||||
|
||||
SPI is available on two of the SAMD20 Xplained connectors, EXT1 and EXT2.
|
||||
They mate with the I/O1 connector as indicated in this table.

|
||||
Development Environment
|
||||
=======================
|
||||
|
||||
Either Linux or Cygwin on Windows can be used for the development environment.
|
||||
The source has been built only using the GNU toolchain (see below). Other
|
||||
toolchains will likely cause problems. Testing was performed using the Cygwin
|
||||
environment.
|
||||
|
||||
GNU Toolchain Options
|
||||
=====================
|
||||
|
||||
|
||||
The NuttX make system can be configured to support the various different
|
||||
toolchain options. All testing has been conducted using the NuttX buildroot
|
||||
toolchain. To use alternative toolchain, you simply need to add change of
|
||||
the following configuration options to your .config (or defconfig) file:
|
||||
|
||||
CONFIG_ARMV6M_TOOLCHAIN_BUILDROOT=y : NuttX buildroot under Linux or Cygwin (default)
|
||||
CONFIG_ARMV6M_TOOLCHAIN_GNU_EABIL=y : Generic GCC ARM EABI toolchain for Linux
|
||||
CONFIG_ARMV6M_TOOLCHAIN_GNU_EABIW=y : Generic GCC ARM EABI toolchain for Windows
|
||||
|
||||
NOTE about Windows native toolchains
|
||||
------------------------------------
|
||||
|
||||
There are basically three kinds of GCC toolchains that can be used:
|
||||
|
||||
1. A Linux native toolchain in a Linux environment,
|
||||
2. The buildroot Cygwin tool chain built in the Cygwin environment,
|
||||
3. A Windows native toolchain.
|
||||
|
||||
There are several limitations to using a Windows based toolchain (#3) in a
|
||||
Cygwin environment. The three biggest are:
|
||||
|
||||
1. The Windows toolchain cannot follow Cygwin paths. Path conversions are
|
||||
performed automatically in the Cygwin makefiles using the 'cygpath'
|
||||
utility but you might easily find some new path problems. If so, check
|
||||
out 'cygpath -w'
|
||||
|
||||
2. Windows toolchains cannot follow Cygwin symbolic links. Many symbolic
|
||||
links are used in NuttX (e.g., include/arch). The make system works
|
||||
around these problems for the Windows tools by copying directories
|
||||
instead of linking them. But this can also cause some confusion for
|
||||
you: For example, you may edit a file in a "linked" directory and find
|
||||
that your changes had no effect. That is because you are building the
|
||||
copy of the file in the "fake" symbolic directory. If you use a
|
||||
Windows toolchain, you should get in the habit of making like this:
|
||||
|
||||
make clean_context all
|
||||
|
||||
An alias in your .bashrc file might make that less painful.
|
||||
|
||||
IDEs
|
||||
====
|
||||
|
||||
NuttX is built using command-line make. It can be used with an IDE, but some
|
||||
effort will be required to create the project.
|
||||
|
||||
Makefile Build
|
||||
--------------
|
||||
Under Eclipse, it is pretty easy to set up an "empty makefile project" and
|
||||
simply use the NuttX makefile to build the system. That is almost for free
|
||||
under Linux. Under Windows, you will need to set up the "Cygwin GCC" empty
|
||||
makefile project in order to work with Windows (Google for "Eclipse Cygwin" -
|
||||
there is a lot of help on the internet).
|
||||
|
||||
Native Build
|
||||
------------
|
||||
Here are a few tips before you start that effort:
|
||||
|
||||
1) Select the toolchain that you will be using in your .config file
|
||||
2) Start the NuttX build at least one time from the Cygwin command line
|
||||
before trying to create your project. This is necessary to create
|
||||
certain auto-generated files and directories that will be needed.
|
||||
3) Set up include paths: You will need include/, arch/arm/src/sam34,
|
||||
arch/arm/src/common, arch/arm/src/armv7-m, and sched/.
|
||||
4) All assembly files need to have the definition option -D __ASSEMBLY__
|
||||
on the command line.
|
||||
|
||||
Startup files will probably cause you some headaches. The NuttX startup file
|
||||
is arch/arm/src/sam34/sam_vectors.S. You may need to build NuttX
|
||||
one time from the Cygwin command line in order to obtain the pre-built
|
||||
startup object needed by an IDE.
|
||||
|
||||
NuttX EABI "buildroot" Toolchain
|
||||
================================
|
||||
|
||||
A GNU GCC-based toolchain is assumed. The PATH environment variable should
|
||||
be modified to point to the correct path to the Cortex-M0 GCC toolchain (if
|
||||
different from the default in your PATH variable).
|
||||
|
||||
If you have no Cortex-M0 toolchain, one can be downloaded from the NuttX
|
||||
Bitbucket download site (https://bitbucket.org/nuttx/buildroot/downloads/).
|
||||
This GNU toolchain builds and executes in the Linux or Cygwin environment.
|
||||
|
||||
1. You must have already configured NuttX in <some-dir>/nuttx.
|
||||
|
||||
tools/configure.sh samd20-xplained:<sub-dir>
|
||||
|
||||
2. Download the latest buildroot package into <some-dir>
|
||||
|
||||
3. unpack the buildroot tarball. The resulting directory may
|
||||
have versioning information on it like buildroot-x.y.z. If so,
|
||||
rename <some-dir>/buildroot-x.y.z to <some-dir>/buildroot.
|
||||
|
||||
4. cd <some-dir>/buildroot
|
||||
|
||||
5. cp boards/cortexm0-eabi-defconfig-4.6.3 .config
|
||||
|
||||
6. make oldconfig
|
||||
|
||||
7. make
|
||||
|
||||
8. Make sure that the PATH variable includes the path to the newly built
|
||||
binaries.
|
||||
|
||||
See the file boards/README.txt in the buildroot source tree. That has more
|
||||
details PLUS some special instructions that you will need to follow if you are
|
||||
building a Cortex-M0 toolchain for Cygwin under Windows.
|
||||
|
||||
LEDs
|
||||
====
|
||||
|
||||
There is one yellow LED available on the SAM D20 Xplained Pro board that
|
||||
can be turned on and off. The LED can be activated by driving the connected
|
||||
PA14 I/O line to GND.
|
||||
|
||||
When CONFIG_ARCH_LEDS is defined in the NuttX configuration, NuttX will
|
||||
control the LED as follows:
|
||||
|
||||
SYMBOL Meaning LED0
|
||||
------------------- ----------------------- ------
|
||||
LED_STARTED NuttX has been started OFF
|
||||
LED_HEAPALLOCATE Heap has been allocated OFF
|
||||
LED_IRQSENABLED Interrupts enabled OFF
|
||||
LED_STACKCREATED Idle stack created ON
|
||||
LED_INIRQ In an interrupt N/C
|
||||
LED_SIGNAL In a signal handler N/C
|
||||
LED_ASSERTION An assertion failed N/C
|
||||
LED_PANIC The system has crashed FLASH
|
||||
|
||||
Thus is LED is statically on, NuttX has successfully booted and is,
|
||||
apparently, running normally. If LED is flashing at approximately
|
||||
2Hz, then a fatal error has been detected and the system has halted.
|
||||
|
||||
Serial Consoles
|
||||
===============
|
||||
|
||||
SERCOM4
|
||||
------
|
||||
|
||||
SERCOM4 is available on connectors EXT1, EXT2, and EXT3, but using
|
||||
different PORT pins:

|
||||
19 GND GND GND N/A
|
||||
20 VCC VCC VCC N/A
|
||||
|
||||
There are options available in the NuttX configuration to select which
|
||||
connector SERCOM4 is on: SAMD20_XPLAINED_USART4_EXTn, where n=1, 2, or 3.
|
||||
|
||||
If you have a TTL to RS-232 converter then this is the most convenient
|
||||
serial console to use (because you don't lose the console device each time
|
||||
you lose the USB connection). It is the default in all of these
|
||||
configurations. An option is to use the virtual COM port.
|
||||
|
||||
Virtual COM Port
|
||||
----------------
|
||||
|
||||
The SAMD20 Xplained Pro contains an Embedded Debugger (EDBG) that can be
|
||||
used to program and debug the ATSAMD20J18A using Serial Wire Debug (SWD).
|
||||
The Embedded debugger also include a Virtual COM port interface over
|
||||
SERCOM3. Virtual COM port connections:
|
||||
|
||||
PA24 SERCOM3 / USART TXD
|
||||
PA25 SERCOM3 / USART RXD
|
||||

|
||||
|
||||
Tools menus: Tools -> Device Programming.
|
||||
|
||||
Debugging the NuttX Object File
|
||||
-------------------------------
|
||||
|
||||
1) Rename object file from nutt to nuttx.elf. That is an extension that
|
||||
will be recognized by the file menu.
|
||||
|
||||
2) File menu: File -> Open -> Open object file for debugging
|
||||
|
||||
- Select nuttx.elf object file
|
||||
- Select AT91SAMD20J18
|
||||
- Select files for symbols as desired
|
||||
- Select debugger
|
||||
|
||||
3) Debug menu: Debug -> Start debugging and break
|
||||
|
||||
- This will reload the nuttx.elf file into FLASH
|
||||
|
||||

|
||||
Some subsystems can be configured to operate in different ways. The drivers
|
||||
need to know how to configure the subsystem.

Configurations
|
||||
==============
|
||||
|
||||
Each SAMD20 Xplained Pro configuration is maintained in a sub-directory and
|
||||
can be selected as follow:
|
||||
|
||||
tools/configure.sh samd20-xplained:<subdir>
|
||||
|
||||
Before building, make sure that the PATH environment variable include the
|
||||
correct path to the directory than holds your toolchain binaries.
|
||||
|
||||
And then build NuttX by simply typing the following. At the conclusion of
|
||||
the make, the nuttx binary will reside in an ELF file called, simply, nuttx.
|
||||
|
||||
make
|
||||
|
||||
The <subdir> that is provided above as an argument to the tools/configure.sh
|
||||
must be is one of the following.
|
||||
|
||||
NOTE: These configurations use the mconf-based configuration tool. To
|
||||
change any of these configurations using that tool, you should:
|
||||
|
||||
a. Build and install the kconfig-mconf tool. See nuttx/README.txt
|
||||
see additional README.txt files in the NuttX tools repository.
|
||||
|
||||
b. Execute 'make menuconfig' in nuttx/ in order to start the
|
||||
reconfiguration process.
|
||||
|
||||
NOTES:
|
||||
|
||||
1. These configurations use the mconf-based configuration tool. To
|
||||
change any of these configurations using that tool, you should:
|
||||
|
||||
a. Build and install the kconfig-mconf tool. See nuttx/README.txt
|
||||
see additional README.txt files in the NuttX tools repository.
|
||||
|
||||
b. Execute 'make menuconfig' in nuttx/ in order to start the
|
||||
reconfiguration process.
|
||||
|
||||
2. Unless stated otherwise, all configurations generate console
|
||||
output of on SERCOM4 which is available on EXT1, EXT2, or EXT3 (see
|
||||
the section "Serial Consoles" above). The virtual COM port could
|
||||
be used, instead, by reconfiguring to use SERCOM3 instead of
|
||||
SERCOM4:
|
||||
|
||||
System Type -> SAMD/L Peripheral Support
|
||||
CONFIG_SAMD2L2_SERCOM3=y : Enable one or both
|
||||
CONFIG_SAMD2L2_SERCOM4=n
|
||||
|
||||
Device Drivers -> Serial Driver Support -> Serial Console
|
||||
CONFIG_USART4_SERIAL_CONSOLE=y : Select only one for the console
|
||||
CONFIG_USART4_SERIAL_CONSOLE=n
|
||||
|
||||
Device Drivers -> Serial Driver Support -> SERCOM3 Configuration
|
||||
CONFIG_USART3_2STOP=0
|
||||
CONFIG_USART3_BAUD=115200
|
||||
CONFIG_USART3_BITS=8
|
||||
CONFIG_USART3_PARITY=0
|
||||
CONFIG_USART3_RXBUFSIZE=256
|
||||
CONFIG_USART3_TXBUFSIZE=256
|
||||
|
||||
Device Drivers -> Serial Driver Support -> SERCOM4 Configuration
|
||||
CONFIG_USART4_2STOP=0
|
||||
CONFIG_USART4_BAUD=115200
|
||||
CONFIG_USART4_BITS=8
|
||||
CONFIG_USART4_PARITY=0
|
||||
CONFIG_USART4_RXBUFSIZE=256
|
||||
CONFIG_USART4_TXBUFSIZE=256
|
||||
|
||||
Board Selection -> USART4 Connection
|
||||
CONFIG_SAMD20_XPLAINED_USART4_EXT1=n : Pick on if USART4 used
|
||||
CONFIG_SAMD20_XPLAINED_USART4_EXT2=n
|
||||
CONFIG_SAMD20_XPLAINED_USART4_EXT3=y
|
||||
|
||||
3. Unless otherwise stated, the configurations are setup for
|
||||
Cygwin under Windows:
|
||||
|
||||
Build Setup:
|
||||
CONFIG_HOST_WINDOWS=y : Windows Host
|
||||
CONFIG_WINDOWS_CYGWIN=y : Cygwin environment on windows
|
||||
|
||||
4. These configurations use the GNU EABI toolchain. But
|
||||
that is easily reconfigured:
|
||||
|
||||
System Type -> Toolchain:
|
||||
CONFIG_ARMV6M_TOOLCHAIN_GNU_EABIW=y
|
||||
|
||||
Any re-configuration should be done before making NuttX or else the
|
||||
subsequent 'make' will fail. If you have already attempted building
|
||||
NuttX then you will have to 1) 'make distclean' to remove the old
|
||||
configuration, 2) 'tools/configure.sh sam3u-ek/ksnh' to start
|
||||
with a fresh configuration, and 3) perform the configuration changes
|
||||
above.
|
||||
|
||||
Also, make sure that your PATH variable has the new path to your
|
||||
Atmel tools. Try 'which arm-none-eabi-gcc' to make sure that you
|
||||
are selecting the right tool.
|
||||
|
||||
See also the "NOTE about Windows native toolchains" in the section
|
||||
called "GNU Toolchain Options" above.
|
||||
|
||||
Configuration sub-directories
|
||||
-----------------------------
|
||||
|
||||
nsh:
|
||||
This configuration directory will built the NuttShell. See NOTES above
|
||||
and below:
|
||||
|
||||
NOTES:
|
||||
|
||||
1. This configuration is set up to build on Windows using the Cygwin
|
||||
environment using the ARM EABI toolchain. This can be easily
|
||||
changed as described above under "Configurations."
|
||||
|
||||
2. By default, this configuration provides a serial console on SERCOM4
|
||||
at 115200 8N1 via EXT3:
|
||||
|
||||
PIN EXT3 GPIO Function
|
||||
---- ---- ------------------
|
||||
13 PB11 SERCOM4 / USART RX
|
||||
14 PB12 SERCOM4 / USART TX
|
||||
19 GND N/A
|
||||
20 VCC N/A
|
||||
|
||||
If you would prefer to use the EDBG serial COM port or would prefer
|
||||
to use SERCOM4 on EXT1 or EXT2, you will need to reconfigure the
|
||||
SERCOM as described under "Configurations". See also the section
|
||||
entitled "Serial Consoles" above.
|
||||
|
||||
3. NOTE: If you get a compilation error like:
|
||||
|
||||
libxx_new.cxx:74:40: error: 'operator new' takes type 'size_t'
|
||||
('unsigned int') as first parameter [-fper
|
||||
|
||||
Sometimes NuttX and your toolchain will disagree on the underlying
|
||||
type of size_t; sometimes it is an 'unsigned int' and sometimes it is
|
||||
an 'unsigned long int'. If this error occurs, then you may need to
|
||||
toggle the value of CONFIG_ARCH_SIZET_LONG.
|
||||
|
||||
4. If the I/O1 module is connected to the SAMD20 Xplained Pro, then
|
||||
support for the SD card slot can be enabled by making the following
|
||||
changes to the configuration. These changes assume that the I/O1
|
||||
modules is connected in EXT1. Most of the modifications necessary
|
||||
to work with the I/O1 in a different connector are obvious.. except
|
||||
for the selection of SERCOM SPI support:
|
||||
|
||||
EXT1: SPI is provided through SERCOM0
|
||||
EXT2: SPI is provided through SERCOM1
|
||||
EXT3: SPI is provided through SERCOM5
|
||||
|
||||
File Systems:
|
||||
CONFIG_FS_FAT=y : Enable the FAT file system
|
||||
CONFIG_FAT_LCNAMES=y : Enable upper/lower case 8.3 file names (Optional, see below)
|
||||
CONFIG_FAT_LFN=y : Enable long file named (Optional, see below)
|
||||
CONFIG_FAT_MAXFNAME=32 : Maximum supported file name length
|
||||
|
||||
There are issues related to patents that Microsoft holds on FAT long
|
||||
file name technologies. See the top level NOTICE file for further
|
||||
details.
|
||||
|
||||
System Type -> Peripherals:
|
||||
CONFIG_SAMD2L2_SERCOM0=y : Use SERCOM0 if the I/O is in EXT1
|
||||
CONFIG_SAMD2L2_SERCOM0_ISSPI=y : Configure SERCOM0 as an SPI master
|
||||
|
||||
Device Drivers
|
||||
CONFIG_SPI=y : Enable SPI support
|
||||
CONFIG_SPI_EXCHANGE=y : The exchange() method is supported
|
||||
|
||||
CONFIG_MMCSD=y : Enable MMC/SD support
|
||||
CONFIG_MMCSD_NSLOTS=1 : Only one MMC/SD card slot
|
||||
CONFIG_MMCSD_MULTIBLOCK_DISABLE=n : Should not need to disable multi-block transfers
|
||||
CONFIG_MMCSD_MMCSUPPORT=n : May interfere with some SD cards
|
||||
CONFIG_MMCSD_HAVE_CARDDETECT=y : I/O1 module as a card detect GPIO
|
||||
CONFIG_MMCSD_SPI=y : Use the SPI interface to the MMC/SD card
|
||||
CONFIG_MMCSD_SPICLOCK=20000000 : This is a guess for the optimal MMC/SD frequency
|
||||
CONFIG_MMCSD_SPIMODE=0 : Mode 0 is required
|
||||
|
||||
Board Selection -> Common Board Options
|
||||
CONFIG_NSH_MMCSDSLOTNO=0 : Only one MMC/SD slot, slot 0
|
||||
CONFIG_NSH_MMCSDSPIPORTNO=0 : Use port=0 -> SERCOM0 if the I/O1 is in EXT1
|
||||
|
||||
Board Selection -> SAMD20 Xplained Pro Modules
|
||||
CONFIG_SAMD20_XPLAINED_IOMODULE=y : I/O1 module is connected
|
||||
CONFIG_SAMD20_XPLAINED_IOMODULE_EXT1=y : I/O1 modules is in EXT1
|
||||
|
||||
Application Configuration -> NSH Library
|
||||
CONFIG_NSH_ARCHINIT=y : Board has architecture-specific initialization
|
||||
|
||||
NOTE: If you enable the I/O1 this configuration with SERCOM4 as the
|
||||
console and with the I/O1 module in EXT1, you *must* remove USART
|
||||
jumper. Otherwise, you have lookpack on SERCOM4 and NSH will *not*
|
||||
behave very well (since its outgoing prompts also appear as incoming
|
||||
commands).
|
||||
|
||||
STATUS: As of 2013-6-18, this configuration appears completely
|
||||
functional. Testing, however, has been very light. Example:
|
||||
|
||||
NuttShell (NSH) NuttX-6.34
|
||||
nsh> mount -t vfat /dev/mmcsd0 /mnt/stuff
|
||||
nsh> ls /mnt/stuff
|
||||
/mnt/stuff:
|
||||
nsh> echo "This is a test" >/mnt/stuff/atest.txt
|
||||
nsh> ls /mnt/stuff
|
||||
/mnt/stuff:
|
||||
atest.txt
|
||||
nsh> cat /mnt/stuff/atest.txt
|
||||
This is a test
|
||||
nsh>
|
||||
|
||||
5. If the OLED1 module is connected to the SAMD20 Xplained Pro, then
|
||||
support for the OLED display can be enabled by making the following
|
||||
changes to the configuration. These changes assume that the I/O1
|
||||
modules is connected in EXT1. Most of the modifications necessary
|
||||
to work with the I/O1 in a different connector are obvious.. except
|
||||
for the selection of SERCOM SPI support:
|
||||
|
||||
EXT1: SPI is provided through SERCOM0
|
||||
EXT2: SPI is provided through SERCOM1
|
||||
EXT3: SPI is provided through SERCOM5
|
||||
|
||||
System Type -> Peripherals:
|
||||
CONFIG_SAMD2L2_SERCOM1=y : Use SERCOM1 if the I/O is in EXT2
|
||||
CONFIG_SAMD2L2_SERCOM1_ISSPI=y : Configure SERCOM1 as an SPI master
|
||||
|
||||
Device Drivers -> SPI
|
||||
CONFIG_SPI=y : Enable SPI support
|
||||
CONFIG_SPI_EXCHANGE=y : The exchange() method is supported
|
||||
CONFIG_SPI_CMDDATA=y : CMD/DATA support is required
|
||||
|
||||
Device Drivers -> LCDs
|
||||
CONFIG_LCD=y : Enable LCD support
|
||||
CONFIG_LCD_MAXCONTRAST=255 : Maximum contrast value
|
||||
CONFIG_LCD_LANDSCAPE=y : Landscape orientation (see below*)
|
||||
CONFIG_LCD_UG2832HSWEG04=y : Enable support for the OLED
|
||||
CONFIG_LCD_SSD1306_SPIMODE=0 : SPI Mode 0
|
||||
CONFIG_LCD_SSD1306_SPIMODE=3500000 : Pick an SPI frequency
|
||||
|
||||
Board Selection -> SAMD20 Xplained Pro Modules
|
||||
CONFIG_SAMD20_XPLAINED_OLED1MODULE=y : OLED1 module is connected
|
||||
CONFIG_SAMD20_XPLAINED_OLED1MODULE_EXT2=y : OLED1 modules is in EXT2
|
||||
|
||||
The NX graphics subsystem also needs to be configured:
|
||||
|
||||
CONFIG_NX=y : Enable graphics support
|
||||
CONFIG_NX_LCDDRIVER=y : Using an LCD driver
|
||||
CONFIG_NX_NPLANES=1 : With a single color plane
|
||||
CONFIG_NX_WRITEONLY=n : You can read from the LCD (see below**)
|
||||
CONFIG_NX_DISABLE_2BPP=y : Disable all resolutions except 1BPP
|
||||
CONFIG_NX_DISABLE_4BPP=y
|
||||
CONFIG_NX_DISABLE_8BPP=y
|
||||
CONFIG_NX_DISABLE_16BPP=y
|
||||
CONFIG_NX_DISABLE_24BPP=y
|
||||
CONFIG_NX_DISABLE_32BPP=y
|
||||
CONFIG_NX_PACKEDMSFIRST=y : LSB packed first (shouldn't matter)
|
||||
CONFIG_NXSTART_EXTERNINIT=y : We have board_graphics_setup()
|
||||
CONFIG_NXTK_BORDERWIDTH=2 : Use a small border
|
||||
CONFIG_NXTK_DEFAULT_BORDERCOLORS=y : Default border colors
|
||||
CONFIG_NXFONTS_CHARBITS=7 : 7-bit fonts
|
||||
CONFIG_NXFONT_SANS17X23B=y : Pick a font (any that will fit)
|
||||
|
||||
* This orientation will put the buttons "above" the LCD. The
|
||||
reverse landscape configuration (CONFIG_LCD_RLANDSCAPE) will
|
||||
"flip" the display so that the buttons are "below" the LCD.
|
||||
|
||||
** The hardware is write only, but the driver maintains a frame buffer
|
||||
to support read and read-write-modiry operations on the LCD.
|
||||
Reading from the frame buffer is, however, untested.
|
||||
|
||||
Then, in order to use the OLED, you will need to build some kind of
|
||||
graphics application or use one of the NuttX graphics examples.
|
||||
Here, for example, is the setup for the graphic "Hello, World!"
|
||||
example:
|
||||
|
||||
CONFIG_EXAMPLES_NXHELLO=y : Enables the example
|
||||
CONFIG_EXAMPLES_NXHELLO_DEFAULT_COLORS=y : Use default colors (see below *)
|
||||
CONFIG_EXAMPLES_NXHELLO_DEFAULT_FONT=y : Use the default font
|
||||
CONFIG_EXAMPLES_NXHELLO_BPP=1 : One bit per pixel
|
||||
CONFIG_EXAMPLES_NXHELLO_EXTERNINIT=y : Special initialization is required.
|
||||
|
||||
* The OLED is monochrome so the only "colors" are blacka nd white.
|
||||
The default "colors" will give you while text on a black background.
|
||||
You can override the faults it you want black text on a while background.
|
||||
|
||||
NOTE: One issue that I have seen with the NXHello example when
|
||||
running as an NSH command is that it only works the first time.
|
||||
So, after you run the 'nxhello' command one time, you will have to
|
||||
reset the board before you run it again.
|
||||
|
||||
This is clearly some issue with initializing, un-initializing, and
|
||||
then re-initializing. If you want to fix this, patches are quite
|
||||
welcome.

* OSC8M Output = 8MHz
|
||||
* `- GCLK1 Input = 8MHz Prescaler = 1 output = 8MHz
|
||||
* `- DFLL Input = 8MHz Multiplier = 6 output = 48MHz
|
||||
* `- GCLK0 Input = 48MHz Prescaler = 1 output = 48MHz
|
||||
* `- PM Input = 48Mhz CPU divider = 1 CPU frequency = 48MHz
|
||||
* APBA divider = 1 APBA frequency = 48MHz
|
||||
* APBB divider = 1 APBB frequency = 48MHz
|
||||
* APBC divider = 1 APBC frequency = 48MHz
|
||||
*
|
||||
* The SAMD20 Xplained Pro has one on-board crystal:
|
||||
*
|
||||
* XC101 32.768KHz XOSC32
|
||||
*
|
||||
* REVISIT: Not currently used, may want to use as GCLK1 source with
|
||||
* DFLL multiplier of ((48000000+16384)/32768) = 1465 which would yield
|
||||
* a clock of 48,005,120 MHz.

* Name: board_app_initialize

*
|

* Description:
|

* Perform application specific initialization. This function is never

* called directly from application code, but only indirectly via the
|
||||
* (non-standard) boardctl() interface using the command BOARDIOC_INIT.
|
||||
*
|
||||
* Input Parameters:
|
||||
* arg - The boardctl() argument is passed to the board_app_initialize()
|
||||
* implementation without modification. The argument has no
|
||||
* meaning to NuttX; the meaning of the argument is a contract
|
||||
* between the board-specific initialization logic and the
|
||||
* matching application logic. The value could be such things as a
|
||||
* mode enumeration value, a set of DIP switch switch settings, a
|
||||
* pointer to configuration data read from a file or serial FLASH,
|
||||
* or whatever you would like to do with it. Every implementation
|
||||
* should accept zero/NULL as a default configuration.
|
||||
*
|
||||
* Returned Value:
|
||||
* Zero (OK) is returned on success; a negated errno value is returned on
|
||||
* any failure to indicate the nature of the failure.

* USB connector.
|

*

|
||||
* PA14 to GND.
|

* Name: sam_spi[n]select, sam_spi[n]status, and sam_spi[n]cmddata
|
||||
*
|
||||
* Description:
|
||||
* These external functions must be provided by board-specific logic.
|
||||
* They include:
|
||||
*
|
||||
* o sam_spi[n]select is a functions to manage the board-specific chip
|
||||
* selects
|
||||
* o sam_spi[n]status and sam_spi[n]cmddata: Implementations of the status
|
||||
* and cmddata methods of the SPI interface defined by struct spi_ops_
|
||||
* (see include/nuttx/spi/spi.h). All other methods including
|
||||
* sam_spibus_initialize()) are provided by common SAMD/L logic.
|
||||
*
|
||||
* Where [n] is the SERCOM number for the SPI module.
|
||||
*
|
||||
* To use this common SPI logic on your board:
|
||||
*
|
||||
* 1. Provide logic in sam_boardinitialize() to configure SPI chip select
|
||||
* pins.
|
||||
* 2. Provide sam_spi[n]select() and sam_spi[n]status() functions in your
|
||||
* board-specific logic. These functions will perform chip selection
|
||||
* and status operations using GPIOs in the way your board is
|
||||
* configured.
|
||||
* 2. If CONFIG_SPI_CMDDATA is defined in the NuttX configuration, provide
|
||||
* sam_spi[n]cmddata() functions in your board-specific logic. This
|
||||
* function will perform cmd/data selection operations using GPIOs in
|
||||
* the way your board is configured.
|
||||
* 3. Add a call to sam_spibus_initialize() in your low level application
|
||||
* initialization logic
|
||||
* 4. The handle returned by sam_spibus_initialize() may then be used to
|
||||
* bind the SPI driver to higher level logic (e.g., calling
|
||||
* mmcsd_spislotinitialize(), for example, will bind the SPI driver to
|
||||
* the SPI MMC/SD driver).

|
||||
* Name: sam_spi[n]select
|
||||
*
|
||||
* Description:
|
||||
* PIO chip select pins may be programmed by the board specific logic in
|
||||
* one of two different ways. First, the pins may be programmed as SPI
|
||||
* peripherals. In that case, the pins are completely controlled by the
|
||||
* SPI driver. This method still needs to be provided, but it may be only
|
||||
* a stub.
|
||||
*
|
||||
* An alternative way to program the PIO chip select pins is as a normal
|
||||
* GPIO output. In that case, the automatic control of the CS pins is
|
||||
* bypassed and this function must provide control of the chip select.
|
||||
* NOTE: In this case, the GPIO output pin does *not* have to be the
|
||||
* same as the NPCS pin normal associated with the chip select number.
|
||||
*
|
||||
* Input Parameters:
|
||||
* dev - SPI device info
|
||||
* devid - Identifies the (logical) device
|
||||
* selected - TRUE:Select the device, FALSE:De-select the device
|
||||

* None

README
|

======
|
||||
|
||||
This README discusses issues unique to NuttX configurations for the
|
||||
Atmel SAMD21 Xplained Pro development board. This board features the
|
||||
ATSAMD21J18A MCU.
|
||||
|
||||
The SAMD21 Xplained Pro Starter Kit may be bundled with three modules:
|
||||
|
||||
1) I/O1 - An MMC/SD card slot, PWM LED control, ADC light sensor, USART
|
||||
loopback, TWI AT30TSE758 Temperature sensor.
|
||||
2) OLED1 - An OLED plus 3 additional switches and 3 additional LEDs
|
||||
3) PROTO1 - A prototyping board with logic on board (other than power-related
|
||||
logic).

STATUS/ISSUES
|
||||
=============
|
||||
|
||||
1. See boards/arm/samd2l2/samd20-xplained/README.txt.
|
||||
This port derives from the SAMD20 Xplained board board and all issues
|
||||
there should apply.
|
||||
|
||||
2. 2015-07-06: The basic NSH configuration is working properly, but
|
||||
not at 115200 baud which is the default BAUD selection in the
|
||||
configurations. It is necessary to drop the BAUD in the
|
||||
configuration.
|
||||
|
||||
I suspect that this is an issue on my board and due to running the
|
||||
system on uncalibrated OSC8M. My bet is that the issue would not
|
||||
exist on many boards or if OSC8M were calibrated or if a more precise
|
||||
clock source were used (like XOSC32K).
|
||||
|
||||
... After more experimentation, I am not sure this conclusion is
|
||||
correct or not. Perhaps the board just comes up with a bad clocking
|
||||
configuration at times????
|
||||
|
||||
Modules
|
||||
=======
|
||||
|
||||
There are several I/O modules available that will work with the SAMD21
|
||||
Xplained Pro Starter Kit:
|
||||
|
||||
1) I/O1 - An MMC/SD card slot, PWM LED control, ADC light sensor, USART
|
||||
loopback, TWI AT30TSE758 Temperature sensor.
|
||||
2) OLED1 - An OLED plus 3 additional switches and 3 additional LEDs
|
||||
3) PROTO1 - A prototyping board with logic on board (other than power-
|
||||
related logic).
|
||||
4) And others. See http://www.atmel.com/products/microcontrollers/avr/xplained.aspx
|
||||
|
||||
Some of these are discussed further below.
|
||||
|
||||
I/O1
|
||||
----
|
||||
The primary function of this module is to provide SD card support, but
|
||||
the full list of modules features include:
|
||||
|
||||
- microSD card connector (SPI interface)
|
||||
- PWM (LED control)
|
||||
- ADC (light sensor)
|
||||
- USART loopback
|
||||
- TWI AT30TSE758 Temperature sensor with EEPROM
|
||||
|
||||
SPI is available on two of the SAMD21 Xplained connectors, EXT1 and EXT2.
|
||||
They mate with the I/O1 connector as indicated in this table.

When a microSD card is put into the connector SW_A and SW_B are short-
|
||||
circuited. SW_A is connected to the microSD_DETECT signal. To use this
|
||||
as a card indicator remember to enable internal pullup in the target
|
||||
device.
|

Configuration Options:
|

----------------------
|
||||
CONFIG_SAMD21_XPLAINED_OLED1MODULE=y : Informs the system that the
|
||||
I/O1 module is installed
|
||||
CONFIG_SAMD21_XPLAINED_OLED1MODULE_EXT1=y : The module is installed in EXT1
|
||||
CONFIG_SAMD21_XPLAINED_OLED1MODULE_EXT2=y : The mdoule is installed in EXT2
|
||||
|
||||
See the set-up in the discussion of the nsh configuration below for other
|
||||
required configuration options.
|
||||
|
||||
PROTO1
|
||||
------
|
||||
A prototyping board with logic on board (other than power-related logic).
|
||||
There is no built-in support for the PROTO1 module.
|
||||
|
||||
LEDs
|
||||
====
|
||||
|
||||
There is one yellow LED available on the SAM D20 Xplained Pro board that
|
||||
can be turned on and off. The LED can be activated by driving the connected
|
||||
PB30 I/O line to GND.
|
||||
|
||||
When CONFIG_ARCH_LEDS is defined in the NuttX configuration, NuttX will
|
||||
control the LED as follows:
|
||||
|
||||
SYMBOL Meaning LED0
|
||||
------------------- ----------------------- ------
|
||||
LED_STARTED NuttX has been started OFF
|
||||
LED_HEAPALLOCATE Heap has been allocated OFF
|
||||
LED_IRQSENABLED Interrupts enabled OFF
|
||||
LED_STACKCREATED Idle stack created ON
|
||||
LED_INIRQ In an interrupt N/C
|
||||
LED_SIGNAL In a signal handler N/C
|
||||
LED_ASSERTION An assertion failed N/C
|
||||
LED_PANIC The system has crashed FLASH
|
||||
|
||||
Thus is LED is statically on, NuttX has successfully booted and is,
|
||||
apparently, running normally. If LED is flashing at approximately
|
||||
2Hz, then a fatal error has been detected and the system has halted.
|
||||
|
||||
Serial Consoles
|
||||
===============
|
||||
|
||||
SERCOM4
|
||||
------
|
||||
|
||||
SERCOM4 is available on connectors EXT1, EXT2, and EXT3, but using
|
||||
different PORT pins:

|
||||
19 GND GND GND N/A
|
||||
20 VCC VCC VCC N/A
|
||||
|
||||
There are options available in the NuttX configuration to select which
|
||||
connector SERCOM4 is on: SAMD21_XPLAINED_USART4_EXTn, where n=1, 2, or 3.
|
||||
|
||||
If you have a TTL to RS-232 converter then this is the most convenient
|
||||
serial console to use (because you don't lose the console device each time
|
||||
you lose the USB connection). It is the default in all of these
|
||||
configurations. An option is to use the virtual COM port.
|
||||
|
||||
Virtual COM Port
|
||||
----------------
|
||||
|
||||
The SAMD21 Xplained Pro contains an Embedded Debugger (EDBG) that can be
|
||||
used to program and debug the ATSAMD21J18A using Serial Wire Debug (SWD).
|
||||
The Embedded debugger also include a Virtual COM port interface over
|
||||
SERCOM3. Virtual COM port connections:
|
||||
|
||||
PA22 SERCOM3 / USART TXD
|
||||
PA23 SERCOM3 / USART RXD
|
||||
|
||||
Atmel Studio 6.1
|
||||
================
|
||||
|
||||
Loading Code into FLASH:
|
||||
-----------------------
|
||||
|
||||
Tools menus: Tools -> Device Programming.
|
||||
|
||||
Debugging the NuttX Object File
|
||||
-------------------------------
|
||||
|
||||
1) Rename object file from nutt to nuttx.elf. That is an extension that
|
||||
will be recognized by the file menu.
|
||||
|
||||
2) File menu: File -> Open -> Open object file for debugging
|
||||
|
||||
- Select nuttx.elf object file
|
||||
- Select AT91SAMD21J18
|
||||
- Select files for symbols as desired
|
||||
- Select debugger
|
||||
|
||||
3) Debug menu: Debug -> Start debugging and break
|
||||
|
||||
- This will reload the nuttx.elf file into FLASH
|
||||
|
||||

Some subsystems can be configured to operate in different ways. The drivers
|
||||
need to know how to configure the subsystem.

Configurations
|
||||
==============
|
||||
|
||||
Each SAMD21 Xplained Pro configuration is maintained in a sub-directory and
|
||||
can be selected as follow:
|
||||
|
||||
tools/configure.sh samd21-xplained:<subdir>
|
||||
|
||||
Before building, make sure the PATH environment variable include the
|
||||
correct path to the directory than holds your toolchain binaries.
|
||||
|
||||
And then build NuttX by simply typing the following. At the conclusion of
|
||||
the make, the nuttx binary will reside in an ELF file called, simply, nuttx.
|
||||
|
||||
make
|
||||
|
||||
The <subdir> that is provided above as an argument to the tools/configure.sh
|
||||
must be is one of the following.
|
||||
|
||||
NOTE: These configurations use the mconf-based configuration tool. To
|
||||
change any of these configurations using that tool, you should:
|
||||
|
||||
a. Build and install the kconfig-mconf tool. See nuttx/README.txt
|
||||
see additional README.txt files in the NuttX tools repository.
|
||||
|
||||
b. Execute 'make menuconfig' in nuttx/ in order to start the
|
||||
reconfiguration process.
|
||||
|
||||
NOTES:
|
||||
|
||||
1. These configurations use the mconf-based configuration tool. To
|
||||
change any of these configurations using that tool, you should:
|
||||
|
||||
a. Build and install the kconfig-mconf tool. See nuttx/README.txt
|
||||
see additional README.txt files in the NuttX tools repository.
|
||||
|
||||
b. Execute 'make menuconfig' in nuttx/ in order to start the
|
||||
reconfiguration process.
|
||||
|
||||
2. Unless stated otherwise, all configurations generate console
|
||||
output of on SERCOM4 which is available on EXT1, EXT2, or EXT3 (see
|
||||
the section "Serial Consoles" above). The virtual COM port could
|
||||
be used, instead, by reconfiguring to use SERCOM3 instead of
|
||||
SERCOM4:
|
||||
|
||||
System Type -> SAMD/L Peripheral Support
|
||||
CONFIG_SAMD2L2_SERCOM3=y : Enable one or both
|
||||
CONFIG_SAMD2L2_SERCOM4=n
|
||||
|
||||
Device Drivers -> Serial Driver Support -> Serial Console
|
||||
CONFIG_USART4_SERIAL_CONSOLE=y : Select only one for the console
|
||||
CONFIG_USART4_SERIAL_CONSOLE=n
|
||||
|
||||
Device Drivers -> Serial Driver Support -> SERCOM3 Configuration
|
||||
CONFIG_USART3_2STOP=0
|
||||
CONFIG_USART3_BAUD=115200
|
||||
CONFIG_USART3_BITS=8
|
||||
CONFIG_USART3_PARITY=0
|
||||
CONFIG_USART3_RXBUFSIZE=256
|
||||
CONFIG_USART3_TXBUFSIZE=256
|
||||
|
||||
Device Drivers -> Serial Driver Support -> SERCOM4 Configuration
|
||||
CONFIG_USART4_2STOP=0
|
||||
CONFIG_USART4_BAUD=115200
|
||||
CONFIG_USART4_BITS=8
|
||||
CONFIG_USART4_PARITY=0
|
||||
CONFIG_USART4_RXBUFSIZE=256
|
||||
CONFIG_USART4_TXBUFSIZE=256
|
||||
|
||||
Board Selection -> USART4 Connection
|
||||
CONFIG_SAMD21_XPLAINED_USART4_EXT1=n : Pick on if USART4 used
|
||||
CONFIG_SAMD21_XPLAINED_USART4_EXT2=n
|
||||
CONFIG_SAMD21_XPLAINED_USART4_EXT3=y
|
||||
|
||||
3. Unless otherwise stated, the configurations are setup for
|
||||
Cygwin under Windows:
|
||||
|
||||
Build Setup:
|
||||
CONFIG_HOST_WINDOWS=y : Windows Host
|
||||
CONFIG_WINDOWS_CYGWIN=y : Cygwin environment on windows
|
||||
|
||||
4. These configurations use the ARM EABI toolchain. But
|
||||
that is easily reconfigured:
|
||||
|
||||
System Type -> Toolchain:
|
||||
CONFIG_ARMV6M_TOOLCHAIN_GNU_EABIW=y
|
||||
|
||||
Any re-configuration should be done before making NuttX or else the
|
||||
subsequent 'make' will fail. If you have already attempted building
|
||||
NuttX then you will have to 1) 'make distclean' to remove the old
|
||||
configuration, 2) 'tools/configure.sh sam3u-ek/ksnh' to start
|
||||
with a fresh configuration, and 3) perform the configuration changes
|
||||
above.
|
||||
|
||||
Also, make sure that your PATH variable has the new path to your
|
||||
Atmel tools. Try 'which arm-none-eabi-gcc' to make sure that you
|
||||
are selecting the right tool.
|
||||
|
||||
See also the "NOTE about Windows native toolchains" in the section
|
||||
called "GNU Toolchain Options" above.
|
||||
|
||||
Configuration sub-directories
|
||||
-----------------------------
|
||||
|
||||
nsh:
|
||||
This configuration directory will built the NuttShell. See NOTES above
|
||||
and below:
|
||||
|
||||
NOTES:
|
||||
|
||||
1. This configuration is set up to build on Windows using the Cygwin
|
||||
environment using the ARM EABI toolchain. This can be easily
|
||||
changed as described above under "Configurations."
|
||||
|
||||
2. By default, this configuration provides a serial console on SERCOM4
|
||||
at 115200 8N1 via EXT3:
|
||||
|
||||
PIN EXT3 GPIO Function
|
||||
---- ---- ------------------
|
||||
13 PB11 SERCOM4 / USART RX
|
||||
14 PB10 SERCOM4 / USART TX
|
||||
19 GND N/A
|
||||
20 VCC N/A
|
||||
|
||||
If you would prefer to use the EDBG serial COM port or would prefer
|
||||
to use SERCOM4 on EXT1 or EXT2, you will need to reconfigure the
|
||||
SERCOM as described under "Configurations". See also the section
|
||||
entitled "Serial Consoles" above.
|
||||
|
||||
3. NOTE: If you get a compilation error like:
|
||||
|
||||
libxx_new.cxx:74:40: error: 'operator new' takes type 'size_t'
|
||||
('unsigned int') as first parameter [-fper
|
||||
|
||||
Sometimes NuttX and your toolchain will disagree on the underlying
|
||||
type of size_t; sometimes it is an 'unsigned int' and sometimes it is
|
||||
an 'unsigned long int'. If this error occurs, then you may need to
|
||||
toggle the value of CONFIG_ARCH_SIZET_LONG.
|
||||
|
||||
4. If the I/O1 module is connected to the SAMD21 Xplained Pro, then
|
||||
support for the SD card slot can be enabled by making the following
|
||||
changes to the configuration. These changes assume that the I/O1
|
||||
modules is connected in EXT1. Most of the modifications necessary
|
||||
to work with the I/O1 in a different connector are obvious.. except
|
||||
for the selection of SERCOM SPI support:
|
||||
|
||||
EXT1: SPI is provided through SERCOM0
|
||||
EXT2: SPI is provided through SERCOM1
|
||||
EXT3: SPI is provided through SERCOM5
|
||||
|
||||
File Systems:
|
||||
CONFIG_FS_FAT=y : Enable the FAT file system
|
||||
CONFIG_FAT_LCNAMES=y : Enable upper/lower case 8.3 file names (Optional, see below)
|
||||
CONFIG_FAT_LFN=y : Enable long file named (Optional, see below)
|
||||
CONFIG_FAT_MAXFNAME=32 : Maximum supported file name length
|
||||
|
||||
There are issues related to patents that Microsoft holds on FAT long
|
||||
file name technologies. See the top level NOTICE file for further
|
||||
details.
|
||||
|
||||
System Type -> Peripherals:
|
||||
CONFIG_SAMD2L2_SERCOM0=y : Use SERCOM0 if the I/O is in EXT1
|
||||
CONFIG_SAMD2L2_SERCOM0_ISSPI=y : Configure SERCOM0 as an SPI master
|
||||
|
||||
Device Drivers
|
||||
CONFIG_SPI=y : Enable SPI support
|
||||
CONFIG_SPI_EXCHANGE=y : The exchange() method is supported
|
||||
|
||||
CONFIG_MMCSD=y : Enable MMC/SD support
|
||||
CONFIG_MMCSD_NSLOTS=1 : Only one MMC/SD card slot
|
||||
CONFIG_MMCSD_MULTIBLOCK_DISABLE=n : Should not need to disable multi-block transfers
|
||||
CONFIG_MMCSD_MMCSUPPORT=n : May interfere with some SD cards
|
||||
CONFIG_MMCSD_HAVE_CARDDETECT=y : I/O1 module as a card detect GPIO
|
||||
CONFIG_MMCSD_SPI=y : Use the SPI interface to the MMC/SD card
|
||||
CONFIG_MMCSD_SPICLOCK=20000000 : This is a guess for the optimal MMC/SD frequency
|
||||
CONFIG_MMCSD_SPIMODE=0 : Mode 0 is required
|
||||
|
||||
Board Selection -> Common Board Options
|
||||
CONFIG_NSH_MMCSDSLOTNO=0 : Only one MMC/SD slot, slot 0
|
||||
CONFIG_NSH_MMCSDSPIPORTNO=0 : Use port=0 -> SERCOM0 if the I/O1 is in EXT1
|
||||
|
||||
Board Selection -> SAMD21 Xplained Pro Modules
|
||||
CONFIG_SAMD21_XPLAINED_IOMODULE=y : I/O1 module is connected
|
||||
CONFIG_SAMD21_XPLAINED_IOMODULE_EXT1=y : I/O1 modules is in EXT1
|
||||
|
||||
Application Configuration -> NSH Library
|
||||
CONFIG_NSH_ARCHINIT=y : Board has architecture-specific initialization
|
||||
|
||||
NOTE: If you enable the I/O1 this configuration with SERCOM4 as the
|
||||
console and with the I/O1 module in EXT1, you *must* remove USART
|
||||
jumper. Otherwise, you have lookpack on SERCOM4 and NSH will *not*
|
||||
behave very well (since its outgoing prompts also appear as incoming
|
||||
commands).
|
||||
|
||||
STATUS: As of 2013-6-18, this configuration appears completely
|
||||
functional. Testing, however, has been very light. Example:
|
||||
|
||||
NuttShell (NSH) NuttX-6.34
|
||||
nsh> mount -t vfat /dev/mmcsd0 /mnt/stuff
|
||||
nsh> ls /mnt/stuff
|
||||
/mnt/stuff:
|
||||
nsh> echo "This is a test" >/mnt/stuff/atest.txt
|
||||
nsh> ls /mnt/stuff
|
||||
/mnt/stuff:
|
||||
atest.txt
|
||||
nsh> cat /mnt/stuff/atest.txt
|
||||
This is a test
|
||||
nsh>
|
||||
|
||||
5. If the OLED1 module is connected to the SAMD21 Xplained Pro, then
|
||||
support for the OLED display can be enabled by making the following
|
||||
changes to the configuration. These changes assume that the I/O1
|
||||
modules is connected in EXT1. Most of the modifications necessary
|
||||
to work with the I/O1 in a different connector are obvious.. except
|
||||
for the selection of SERCOM SPI support:
|
||||
|
||||
EXT1: SPI is provided through SERCOM0
|
||||
EXT2: SPI is provided through SERCOM1
|
||||
EXT3: SPI is provided through SERCOM5
|
||||
|
||||
System Type -> Peripherals:
|
||||
CONFIG_SAMD2L2_SERCOM1=y : Use SERCOM1 if the I/O is in EXT2
|
||||
CONFIG_SAMD2L2_SERCOM1_ISSPI=y : Configure SERCOM1 as an SPI master
|
||||
|
||||
Device Drivers -> SPI
|
||||
CONFIG_SPI=y : Enable SPI support
|
||||
CONFIG_SPI_EXCHANGE=y : The exchange() method is supported
|
||||
CONFIG_SPI_CMDDATA=y : CMD/DATA support is required
|
||||
|
||||
Device Drivers -> LCDs
|
||||
CONFIG_LCD=y : Enable LCD support
|
||||
CONFIG_LCD_MAXCONTRAST=255 : Maximum contrast value
|
||||
CONFIG_LCD_LANDSCAPE=y : Landscape orientation (see below*)
|
||||
CONFIG_LCD_UG2832HSWEG04=y : Enable support for the OLED
|
||||
CONFIG_LCD_SSD1306_SPIMODE=0 : SPI Mode 0
|
||||
CONFIG_LCD_SSD1306_SPIMODE=3500000 : Pick an SPI frequency
|
||||
|
||||
Board Selection -> SAMD21 Xplained Pro Modules
|
||||
CONFIG_SAMD21_XPLAINED_OLED1MODULE=y : OLED1 module is connected
|
||||
CONFIG_SAMD21_XPLAINED_OLED1MODULE_EXT2=y : OLED1 modules is in EXT2
|
||||
|
||||
The NX graphics subsystem also needs to be configured:
|
||||
|
||||
CONFIG_NX=y : Enable graphics support
|
||||
CONFIG_NX_LCDDRIVER=y : Using an LCD driver
|
||||
CONFIG_NX_NPLANES=1 : With a single color plane
|
||||
CONFIG_NX_WRITEONLY=n : You can read from the LCD (see below**)
|
||||
CONFIG_NX_DISABLE_2BPP=y : Disable all resolutions except 1BPP
|
||||
CONFIG_NX_DISABLE_4BPP=y
|
||||
CONFIG_NX_DISABLE_8BPP=y
|
||||
CONFIG_NX_DISABLE_16BPP=y
|
||||
CONFIG_NX_DISABLE_24BPP=y
|
||||
CONFIG_NX_DISABLE_32BPP=y
|
||||
CONFIG_NX_PACKEDMSFIRST=y : LSB packed first (shouldn't matter)
|
||||
CONFIG_NXSTART_EXTERNINIT=y : We have board_graphics_setup()
|
||||
CONFIG_NXTK_BORDERWIDTH=2 : Use a small border
|
||||
CONFIG_NXTK_DEFAULT_BORDERCOLORS=y : Default border colors
|
||||
CONFIG_NXFONTS_CHARBITS=7 : 7-bit fonts
|
||||
CONFIG_NXFONT_SANS17X23B=y : Pick a font (any that will fit)
|
||||
|
||||
* This orientation will put the buttons "above" the LCD. The
|
||||
reverse landscape configuration (CONFIG_LCD_RLANDSCAPE) will
|
||||
"flip" the display so that the buttons are "below" the LCD.
|
||||
|
||||
** The hardware is write only, but the driver maintains a frame buffer
|
||||
to support read and read-write-modiry operations on the LCD.
|
||||
Reading from the frame buffer is, however, untested.
|
||||
|
||||
Then, in order to use the OLED, you will need to build some kind of
|
||||
graphics application or use one of the NuttX graphics examples.
|
||||
Here, for example, is the setup for the graphic "Hello, World!"
|
||||
example:
|
||||
|
||||
CONFIG_EXAMPLES_NXHELLO=y : Enables the example
|
||||
CONFIG_EXAMPLES_NXHELLO_DEFAULT_COLORS=y : Use default colors (see below *)
|
||||
CONFIG_EXAMPLES_NXHELLO_DEFAULT_FONT=y : Use the default font
|
||||
CONFIG_EXAMPLES_NXHELLO_BPP=1 : One bit per pixel
|
||||
CONFIG_EXAMPLES_NXHELLO_EXTERNINIT=y : Special initialization is required.
|
||||
|
||||
* The OLED is monochrome so the only "colors" are blacka nd white.
|
||||
The default "colors" will give you while text on a black background.
|
||||
You can override the faults it you want black text on a while background.
|
||||
|
||||
NOTE: One issue that I have seen with the NXHello example when
|
||||
running as an NSH command is that it only works the first time.
|
||||
So, after you run the 'nxhello' command one time, you will have to
|
||||
reset the board before you run it again.
|
||||
|
||||
This is clearly some issue with initializing, un-initializing, and
|
||||
then re-initializing. If you want to fix this, patches are quite
|
||||
welcome.

* OSC8M Output = 8MHz
|

* `- GCLK1 Input = 8MHz Prescaler = 1 output = 8MHz
|
||||
* `- DFLL Input = 8MHz Multiplier = 6 output = 48MHz
|

* `- GCLK0 Input = 48MHz Prescaler = 1 output = 48MHz
|

* `- PM Input = 48Mhz CPU divider = 1 CPU frequency = 48MHz
|

* APBA divider = 1 APBA frequency = 48MHz
|

* APBB divider = 1 APBB frequency = 48MHz
|
||||
* APBC divider = 1 APBC frequency = 48MHz
|

*
|

* The SAMD21 Xplained Pro has one on-board crystal:
|

*
|
||||
* XC101 32.768KHz XOSC32
|
||||
*
|
||||
* REVISIT: Not currently used, may want to use as GCLK1 source with
|
||||
* DFLL multiplier of ((48000000+16384)/32768) = 1465 which would yield
|
||||
* a clock of 48,005,120 MHz.

* Name: board_app_initialize
|

*
|
||||
* Description:
|
||||
* Perform application specific initialization. This function is never
|
||||
* called directly from application code, but only indirectly via the
|
||||
* (non-standard) boardctl() interface using the command BOARDIOC_INIT.
|
||||
*
|
||||
* Input Parameters:
|
||||
* arg - The boardctl() argument is passed to the board_app_initialize()
|
||||
* implementation without modification. The argument has no
|
||||
* meaning to NuttX; the meaning of the argument is a contract
|
||||
* between the board-specific initialization logic and the
|
||||
* matching application logic. The value could be such things as a
|
||||
* mode enumeration value, a set of DIP switch switch settings, a
|
||||
* pointer to configuration data read from a file or serial FLASH,
|
||||
* or whatever you would like to do with it. Every implementation
|
||||
* should accept zero/NULL as a default configuration.
|
||||
*
|
||||
* Returned Value:
|
||||
* Zero (OK) is returned on success; a negated errno value is returned on
|
||||
* any failure to indicate the nature of the failure.

/* There are three LEDs on board the SAMD21 Xplained Pro board: The EDBG
|
||||
* controls two of the LEDs, a power LED and a status LED. There is only
|
||||
* one user controllable LED, a yellow LED labelled STATUS near the SAMD21
|
||||
* USB connector.
|
||||
*
|
||||
* This LED is controlled by PB30 and the LED can be activated by driving
|
||||
* PB30 to GND.
|
||||
*
|
||||
* When CONFIG_ARCH_LEDS is defined in the NuttX configuration, NuttX will
|
||||
* control the LED as follows:
|
||||
*
|
||||
* SYMBOL Meaning LED
|
||||
* ------------------- ----------------------- ------
|
||||
* LED_STARTED NuttX has been started OFF
|
||||
* LED_HEAPALLOCATE Heap has been allocated OFF
|
||||
* LED_IRQSENABLED Interrupts enabled OFF
|
||||
* LED_STACKCREATED Idle stack created ON
|
||||
* LED_INIRQ In an interrupt** N/C
|
||||
* LED_SIGNAL In a signal handler*** N/C
|
||||
* LED_ASSERTION An assertion failed N/C
|
||||
* LED_PANIC The system has crashed FLASH
|
||||
*
|
||||
* Thus if the LED is statically on, NuttX has successfully booted and is,
|
||||
* apparently, running normally. If the LED is flashing at approximately
|
||||
* 2Hz, then a fatal error has been detected and the system has halted.

* Name: sam_spi[n]select, sam_spi[n]status, and sam_spi[n]cmddata
|
||||
*
|
||||
* Description:
|
||||
* These external functions must be provided by board-specific logic. They
|
||||
* include:
|
||||
*
|
||||
* o sam_spi[n]select is a functions to manage the board-specific chip
|
||||
* selects
|
||||
* o sam_spi[n]status and sam_spi[n]cmddata: Implementations of the status
|
||||
* and cmddata methods of the SPI interface defined by struct spi_ops_
|
||||
* (see include/nuttx/spi/spi.h). All other methods including
|
||||
* sam_spibus_initialize()) are provided by common SAMD/L logic.
|
||||
*
|
||||
* Where [n] is the SERCOM number for the SPI module.
|
||||
*
|
||||
* To use this common SPI logic on your board:
|
||||
*
|
||||
* 1. Provide logic in sam_boardinitialize() to configure SPI chip select
|
||||
* pins.
|
||||
* 2. Provide sam_spi[n]select() and sam_spi[n]status() functions in your
|
||||
* board-specific logic. These functions will perform chip selection
|
||||
* and status operations using GPIOs in the way your board is
|
||||
* configured.
|
||||
* 2. If CONFIG_SPI_CMDDATA is defined in the NuttX configuration, provide
|
||||
* sam_spi[n]cmddata() functions in your board-specific logic. This
|
||||
* function will perform cmd/data selection operations using GPIOs in
|
||||
* the way your board is configured.
|
||||
* 3. Add a call to sam_spibus_initialize() in your low level application
|
||||
* initialization logic
|
||||
* 4. The handle returned by sam_spibus_initialize() may then be used to
|
||||
* bind the SPI driver to higher level logic (e.g., calling
|
||||
* mmcsd_spislotinitialize(), for example, will bind the SPI driver to
|
||||
* the SPI MMC/SD driver).

|
||||
* Name: sam_spi[n]select
|
||||
*
|
||||
* Description:
|
||||
* PIO chip select pins may be programmed by the board specific logic in
|
||||
* one of two different ways. First, the pins may be programmed as SPI
|
||||
* peripherals. In that case, the pins are completely controlled by the
|
||||
* SPI driver. This method still needs to be provided, but it may be only
|
||||
* a stub.
|
||||
*
|
||||
* An alternative way to program the PIO chip select pins is as a normal
|
||||
* GPIO output. In that case, the automatic control of the CS pins is
|
||||
* bypassed and this function must provide control of the chip select.
|
||||
* NOTE: In this case, the GPIO output pin does *not* have to be the
|
||||
* same as the NPCS pin normal associated with the chip select number.
|
||||
*
|
||||
* Input Parameters:
|
||||
* dev - SPI device info
|
||||
* devid - Identifies the (logical) device
|

STATUS/ISSUES
|
||||
=============
|
||||
|
||||
- Since this port is a leverage of the SAMD20 Xplained port, some of the
|
||||
STATUS/ISSUES in the SAMD20 Xplained README.txt may apply here as well.
|
||||
|
||||
- 2015-5-26: The basic port is running at 48MHz (using 32.768 XTAL input
|
||||
and the digital frequency locked loop). The basic NuttShell (NSH)
|
||||
configuration is working well with the serial console provided by
|
||||
SERCOM4 as 115200 8N1.
|
||||
|
||||
- 2015-6-14: Added a DMAC driver. There is no way to verify it at present
|
||||
and, hence, depends upon CONFIG_EXPERIMENTAL=y
|
||||
|
||||
Modules
|
||||
=======
|
||||
|
||||
There are several I/O modules available that will work with the SAML21
|
||||
Xplained Pro Starter Kit:
|
||||
|
||||
1) I/O1 - An MMC/SD card slot, PWM LED control, ADC light sensor, USART
|
||||
loopback, TWI AT30TSE758 Temperature sensor.
|
||||
2) OLED1 - An OLED plus 3 additional switches and 3 additional LEDs
|
||||
3) PROTO1 - A prototyping board with logic on board (other than power-
|
||||
related logic).
|
||||
4) And others. See http://www.atmel.com/products/microcontrollers/avr/xplained.aspx
|
||||
|
||||
Some of these are discussed further below.
|
||||
|
||||
I/O1
|
||||
----
|
||||
The primary function of this module is to provide SD card support, but
|
||||
the full list of modules features include:
|
||||
|
||||
- microSD card connector (SPI interface)
|
||||
- PWM (LED control)
|
||||
- ADC (light sensor)
|
||||
- USART loopback
|
||||
- TWI AT30TSE758 Temperature sensor with EEPROM
|
||||
|
||||
SPI is available on two of the SAML21 Xplained connectors, EXT1 and EXT2.
|
||||
They mate with the I/O1 connector as indicated in this table.

|

|
||||
Development Environment
|
||||
=======================
|
||||
|
||||
Either Linux or Cygwin on Windows can be used for the development environment.
|
||||
The source has been built only using the GNU toolchain (see below). Other
|
||||
toolchains will likely cause problems. Testing was performed using the Cygwin
|
||||
environment.
|
||||
|
||||
GNU Toolchain Options
|
||||
=====================
|
||||
|
||||
The NuttX make system can be configured to support the various different
|
||||
toolchain options. All testing has been conducted using the NuttX buildroot
|
||||
toolchain. To use alternative toolchain, you simply need to add change of
|
||||
the following configuration options to your .config (or defconfig) file:
|
||||
|
||||
CONFIG_ARMV7M_TOOLCHAIN_BUILDROOT=y : NuttX buildroot under Linux or Cygwin (default)
|
||||
CONFIG_ARMV7M_TOOLCHAIN_GNU_EABIL=y : Generic GCC ARM EABI toolchain for Linux
|
||||
CONFIG_ARMV7M_TOOLCHAIN_GNU_EABIW=y : Generic GCC ARM EABI toolchain for Windows
|
||||
|
||||
NOTE about Windows native toolchains
|
||||
------------------------------------
|
||||
|
||||
There are basically three kinds of GCC toolchains that can be used:
|
||||
|
||||
1. A Linux native toolchain in a Linux environment,
|
||||
2. The buildroot Cygwin tool chain built in the Cygwin environment,
|
||||
3. A Windows native toolchain.
|
||||
|
||||
There are several limitations to using a Windows based toolchain (#3) in a
|
||||
Cygwin environment. The three biggest are:
|
||||
|
||||
1. The Windows toolchain cannot follow Cygwin paths. Path conversions are
|
||||
performed automatically in the Cygwin makefiles using the 'cygpath'
|
||||
utility but you might easily find some new path problems. If so, check
|
||||
out 'cygpath -w'
|
||||
|
||||
2. Windows toolchains cannot follow Cygwin symbolic links. Many symbolic
|
||||
links are used in NuttX (e.g., include/arch). The make system works
|
||||
around these problems for the Windows tools by copying directories
|
||||
instead of linking them. But this can also cause some confusion for
|
||||
you: For example, you may edit a file in a "linked" directory and find
|
||||
that your changes had no effect. That is because you are building the
|
||||
copy of the file in the "fake" symbolic directory. If you use a
|
||||
Windows toolchain, you should get in the habit of making like this:
|
||||
|
||||
make clean_context all
|
||||
|
||||
An alias in your .bashrc file might make that less painful.
|
||||
|
||||
IDEs
|
||||
====
|
||||
|
||||
NuttX is built using command-line make. It can be used with an IDE, but some
|
||||
effort will be required to create the project.
|
||||
|
||||
Makefile Build
|
||||
--------------
|
||||
Under Eclipse, it is pretty easy to set up an "empty makefile project" and
|
||||
simply use the NuttX makefile to build the system. That is almost for free
|
||||
under Linux. Under Windows, you will need to set up the "Cygwin GCC" empty
|
||||
makefile project in order to work with Windows (Google for "Eclipse Cygwin" -
|
||||
there is a lot of help on the internet).
|
||||
|
||||
Native Build
|
||||
------------
|
||||
Here are a few tips before you start that effort:
|
||||
|
||||
1) Select the toolchain that you will be using in your .config file
|
||||
2) Start the NuttX build at least one time from the Cygwin command line
|
||||
before trying to create your project. This is necessary to create
|
||||
certain auto-generated files and directories that will be needed.
|
||||
3) Set up include paths: You will need include/, arch/arm/src/sam34,
|
||||
arch/arm/src/common, arch/arm/src/armv7-m, and sched/.
|
||||
4) All assembly files need to have the definition option -D __ASSEMBLY__
|
||||
on the command line.
|
||||
|
||||
Startup files will probably cause you some headaches. The NuttX startup file
|
||||
is arch/arm/src/sam34/sam_vectors.S. You may need to build NuttX
|
||||
one time from the Cygwin command line in order to obtain the pre-built
|
||||
startup object needed by an IDE.
|
||||
|
||||
NuttX EABI "buildroot" Toolchain
|
||||
================================
|
||||
|
||||
A GNU GCC-based toolchain is assumed. The PATH environment variable should
|
||||
be modified to point to the correct path to the Cortex-M0 GCC toolchain (if
|
||||
different from the default in your PATH variable).
|
||||
|
||||
If you have no Cortex-M0 toolchain, one can be downloaded from the NuttX
|
||||
Bitbucket download site (https://bitbucket.org/nuttx/buildroot/downloads/).
|
||||
This GNU toolchain builds and executes in the Linux or Cygwin environment.
|
||||
|
||||
1. You must have already configured NuttX in <some-dir>/nuttx.
|
||||
|
||||
tools/configure.sh saml21-xplained:<sub-dir>
|
||||
|
||||
2. Download the latest buildroot package into <some-dir>
|
||||
|
||||
3. unpack the buildroot tarball. The resulting directory may
|
||||
have versioning information on it like buildroot-x.y.z. If so,
|
||||
rename <some-dir>/buildroot-x.y.z to <some-dir>/buildroot.
|
||||
|
||||
4. cd <some-dir>/buildroot
|
||||
|
||||
5. cp boards/cortexm0-eabi-defconfig-4.6.3 .config
|
||||
|
||||
6. make oldconfig
|
||||
|
||||
7. make
|
||||
|
||||
8. Make sure that the PATH variable includes the path to the newly built
|
||||
binaries.
|
||||
|
||||
See the file boards/README.txt in the buildroot source tree. That has more
|
||||
details PLUS some special instructions that you will need to follow if you are
|
||||
building a Cortex-M0 toolchain for Cygwin under Windows.
|
||||
|
||||
LEDs and Buttons
|
||||
================
|
||||
|
||||
LED
|
||||
---
|
||||
There is one yellow LED available on the SAML21 Xplained Pro board that
|
||||
can be turned on and off. The LED can be activated by driving the connected
|
||||
PB10 I/O line to GND.
|
||||
|
||||
When CONFIG_ARCH_LEDS is defined in the NuttX configuration, NuttX will
|
||||
control the LED as follows:
|
||||
|
||||
SYMBOL Meaning LED0
|
||||
------------------- ----------------------- ------
|
||||
LED_STARTED NuttX has been started OFF
|
||||
LED_HEAPALLOCATE Heap has been allocated OFF
|
||||
LED_IRQSENABLED Interrupts enabled OFF

LED_SIGNAL In a signal handler N/C
|

LED_ASSERTION An assertion failed N/C
|

LED_PANIC The system has crashed FLASH
|

Thus is LED is statically on, NuttX has successfully booted and is,
|

apparently, running normally. If LED is flashing at approximately
|
||||
2Hz, then a fatal error has been detected and the system has halted.

Button
|
||||
------
|
||||
SAM L21 Xplained Pro contains one mechanical button on PA02 that can be
|
||||
controlled by software. When a button is pressed it will drive the I/O
|
||||
line to GND. Note: There is no pull-up resistor connected to the generic
|
||||
user button. Remember to enable the internal pull-up in the SAM L21 to
|
||||
use the button.

Configuration
|
||||
-------------
|
||||
There are options available in the NuttX configuration to select which
|
||||
connector SERCOM4 is on: SAML21_XPLAINED_USART4_EXTn, where n=1, 2, or 3.
|
||||
|
||||
If you have a TTL to RS-232 converter then this is the most convenient
|
||||
serial console to use (because you don't lose the console device each time
|
||||
you lose the USB connection). It is the default in all of these
|
||||
configurations. An option is to use the virtual COM port.
|
||||
|
||||
Virtual COM Port
|
||||
----------------
|
||||
|
||||
The SAML21 Xplained Pro contains an Embedded Debugger (EDBG) that can be
|
||||
used to program and debug the ATSAML21J18A using Serial Wire Debug (SWD).
|
||||
The Embedded debugger also include a Virtual COM port interface over
|
||||
SERCOM3. Virtual COM port connections:
|
||||
|
||||
PA22 SERCOM3 / USART TXD
|
||||
PA23 SERCOM3 / USART RXD
|
||||
|
||||
Atmel Studio 6.1
|
||||
================
|
||||
|
||||
NOTE: These instructions are old. The SAML21 requires Atmel Studio 6.2.
|
||||
They may still prove useful to you, however.
|
||||
|
||||
Loading Code into FLASH:
|
||||
-----------------------
|
||||
|
||||
Tools menus: Tools -> Device Programming.
|
||||
|
||||
Debugging the NuttX Object File
|
||||
-------------------------------
|
||||
|
||||
1) Rename object file from nutt to nuttx.elf. That is an extension that
|
||||
will be recognized by the file menu.
|
||||
|
||||
2) File menu: File -> Open -> Open object file for debugging
|
||||
|
||||
- Select nuttx.elf object file
|
||||
- Select AT91SAML21J18
|
||||
- Select files for symbols as desired
|
||||
- Select debugger
|
||||
|
||||
3) Debug menu: Debug -> Start debugging and break
|
||||
|
||||
- This will reload the nuttx.elf file into FLASH
|
||||
|
||||
JTAG
|
||||
====
|
||||
|
||||
I did all of the debug of the SAML21 Xplained using a Segger J-Link
|
||||
connected to the micro JTAG connector on board the SAML21 Xplained.
|
||||
I used an Olimex ARM-JTAG 20-10 Adapter to connect the J-Link to
|
||||
the SAML21 Xplained.

Configurations
|
||||
==============
|
||||
|
||||
Each SAML21 Xplained Pro configuration is maintained in a sub-directory and
|
||||
can be selected as follow:
|
||||
|
||||
tools/configure.sh saml21-xplained:<subdir>
|
||||
|
||||
Before building, make sure that the PATH environmental variable includes the
|
||||
correct path to the directory than holds your toolchain binaries.
|
||||
|
||||
And then build NuttX by simply typing the following. At the conclusion of
|
||||
the make, the nuttx binary will reside in an ELF file called, simply, nuttx.
|
||||
|
||||
make
|
||||
|
||||
The <subdir> that is provided above as an argument to the tools/configure.sh
|
||||
must be is one of the following.
|
||||
|
||||
NOTE: These configurations use the mconf-based configuration tool. To
|
||||
change any of these configurations using that tool, you should:
|
||||
|
||||
a. Build and install the kconfig-mconf tool. See nuttx/README.txt
|
||||
see additional README.txt files in the NuttX tools repository.
|
||||
|
||||
b. Execute 'make menuconfig' in nuttx/ in order to start the
|
||||
reconfiguration process.
|
||||
|
||||
NOTES:
|
||||
|
||||
1. These configurations use the mconf-based configuration tool. To
|
||||
change any of these configurations using that tool, you should:
|
||||
|
||||
a. Build and install the kconfig-mconf tool. See nuttx/README.txt
|
||||
see additional README.txt files in the NuttX tools repository.
|
||||
|
||||
b. Execute 'make menuconfig' in nuttx/ in order to start the
|
||||
reconfiguration process.
|
||||
|
||||
2. Unless stated otherwise, all configurations generate console
|
||||
output of on SERCOM4 which is available on EXT1 (see the section
|
||||
"Serial Consoles" above). The SERCOM1 on EXT2 or EXT3 or the
|
||||
virtual COM port on SERCOME could be used, instead, by
|
||||
reconfiguring to use SERCOM1 or SERCOM3 instead of SERCOM4:
|
||||
|
||||
System Type -> SAMD/L Peripheral Support
|
||||
CONFIG_SAMD2L2_SERCOM1=y : Enable one or both
|
||||
CONFIG_SAMD2L2_SERCOM3=y
|
||||
CONFIG_SAMD2L2_SERCOM4=n
|
||||
|
||||
Device Drivers -> Serial Driver Support -> Serial Console
|
||||
CONFIG_USART1_SERIAL_CONSOLE=y : Select only one for the console
|
||||
CONFIG_USART3_SERIAL_CONSOLE=y : Select only one for the console
|
||||
CONFIG_USART4_SERIAL_CONSOLE=n
|
||||
|
||||
Device Drivers -> Serial Driver Support -> SERCOMn Configuration
|
||||
where n=1 or 3:
|
||||
|
||||
CONFIG_USARTn_2STOP=0
|
||||
CONFIG_USARTn_BAUD=115200
|
||||
CONFIG_USARTn_BITS=8
|
||||
CONFIG_USARTn_PARITY=0
|
||||
CONFIG_USARTn_RXBUFSIZE=256
|
||||
CONFIG_USARTn_TXBUFSIZE=256
|
||||
|
||||
3. Unless otherwise stated, the configurations are setup for
|
||||
Cygwin under Windows:
|
||||
|
||||
Build Setup:
|
||||
CONFIG_HOST_WINDOWS=y : Windows Host
|
||||
CONFIG_WINDOWS_CYGWIN=y : Cygwin environment on windows
|
||||
|
||||
4. These configurations use the ARM EABI toolchain. But
|
||||
that is easily reconfigured:
|
||||
|
||||
System Type -> Toolchain:
|
||||
CONFIG_ARMV6M_TOOLCHAIN_GNU_EABIW=y
|
||||
|
||||
Any re-configuration should be done before making NuttX or else the
|
||||
subsequent 'make' will fail. If you have already attempted building
|
||||
NuttX then you will have to 1) 'make distclean' to remove the old
|
||||
configuration, 2) 'tools/configure.sh sam3u-ek/ksnh' to start
|
||||
with a fresh configuration, and 3) perform the configuration changes
|
||||
above.
|
||||
|
||||
Also, make sure that your PATH variable has the new path to your
|
||||
Atmel tools. Try 'which arm-none-eabi-gcc' to make sure that you
|
||||
are selecting the right tool.
|
||||
|
||||
See also the "NOTE about Windows native toolchains" in the section
|
||||
called "GNU Toolchain Options" above.
|
||||
|
||||
Configuration sub-directories
|
||||
-----------------------------
|
||||
|
||||
nsh:
|
||||
This configuration directory will built the NuttShell. See NOTES above
|
||||
and below:
|
||||
|
||||
NOTES:
|
||||
|
||||
1. This configuration is set up to build on Windows using the Cygwin
|
||||
environment using the ARM EABI toolchain. This can be easily
|
||||
changed as described above under "Configurations."
|
||||
|
||||
2. By default, this configuration provides a serial console on SERCOM4
|
||||
at 115200 8N1 via EXT1:
|
||||
|
||||
PIN EXT1 GPIO Function
|
||||
---- ---- ------------------
|
||||
13 PB09 SERCOM4 / USART RX
|
||||
14 PB08 SERCOM4 / USART TX
|
||||
19 GND N/A
|
||||
20 VCC N/A
|
||||
|
||||
If you would prefer to use the EDBG serial COM port or would prefer
|
||||
to use SERCOM4 on EXT1 or EXT2, you will need to reconfigure the
|
||||
SERCOM as described under "Configurations". See also the section
|
||||
entitled "Serial Consoles" above.
|
||||
|
||||
3. NOTE: If you get a compilation error like:
|
||||
|
||||
libxx_new.cxx:74:40: error: 'operator new' takes type 'size_t'
|
||||
('unsigned int') as first parameter [-fper
|
||||
|
||||
Sometimes NuttX and your toolchain will disagree on the underlying
|
||||
type of size_t; sometimes it is an 'unsigned int' and sometimes it is
|
||||
an 'unsigned long int'. If this error occurs, then you may need to
|
||||
toggle the value of CONFIG_ARCH_SIZET_LONG.
|
||||
|
||||
4. WARNING: This info comes from the SAMD20 Xplained README. I have
|
||||
not tried the I/O1 module on the SAML21!
|
||||
|
||||
If the I/O1 module is connected to the SAML21 Xplained Pro, then
|
||||
support for the SD card slot can be enabled by making the following
|
||||
changes to the configuration. These changes assume that the I/O1
|
||||
modules is connected in EXT1. Most of the modifications necessary
|
||||
to work with the I/O1 in a different connector are obvious.. except
|
||||
for the selection of SERCOM SPI support:
|
||||
|
||||
EXT1: SPI is provided through SERCOM0
|
||||
EXT2: SPI is provided through SERCOM1
|
||||
EXT3: SPI is provided through SERCOM5

CONFIG_NSH_ARCHINIT=y : Board has architecture-specific initialization
|
||||
|
||||
NOTE: If you enable the I/O1 this configuration with SERCOM4 as the
|
||||
console and with the I/O1 module in EXT1, you *must* remove USART
|
||||
jumper. Otherwise, you have lookback on SERCOM4 and NSH will *not*
|
||||
behave very well (since its outgoing prompts also appear as incoming
|
||||
commands).
|
||||
|
||||
STATUS: As of 2013-6-18, this configuration appears completely
|

CONFIG_SPI=y : Enable SPI support
|
||||
CONFIG_SPI_EXCHANGE=y : The exchange() method is supported
|
||||
CONFIG_SPI_CMDDATA=y : CMD/DATA support is required
|
||||
|
||||
Device Drivers -> LCDs
|
||||
CONFIG_LCD=y : Enable LCD support
|
||||
CONFIG_LCD_MAXCONTRAST=255 : Maximum contrast value
|
||||
CONFIG_LCD_LANDSCAPE=y : Landscape orientation (see below*)
|
||||
CONFIG_LCD_UG2832HSWEG04=y : Enable support for the OLED
|
||||
CONFIG_LCD_SSD1306_SPIMODE=0 : SPI Mode 0
|

Board Selection -> SAML21 Xplained Pro Modules
|
||||
CONFIG_SAML21_XPLAINED_OLED1MODULE=y : OLED1 module is connected
|
||||
CONFIG_SAML21_XPLAINED_OLED1MODULE_EXT2=y : OLED1 modules is in EXT2
|
||||
|
||||
The NX graphics subsystem also needs to be configured:
|
||||
|
||||
CONFIG_NX=y : Enable graphics support
|
||||
CONFIG_NX_LCDDRIVER=y : Using an LCD driver
|
||||
CONFIG_NX_NPLANES=1 : With a single color plane
|
||||
CONFIG_NX_WRITEONLY=n : You can read from the LCD (see below*)
|
||||
CONFIG_NX_DISABLE_2BPP=y : Disable all resolutions except 1BPP
|
||||
CONFIG_NX_DISABLE_4BPP=y
|
||||
CONFIG_NX_DISABLE_8BPP=y
|
||||
CONFIG_NX_DISABLE_16BPP=y
|
||||
CONFIG_NX_DISABLE_24BPP=y
|
||||
CONFIG_NX_DISABLE_32BPP=y
|
||||
CONFIG_NX_PACKEDMSFIRST=y : LSB packed first (shouldn't matter)
|
||||
CONFIG_NXSTART_EXTERNINIT=y : We have board_graphics_setup()
|
||||
CONFIG_NXTK_BORDERWIDTH=2 : Use a small border
|
||||
CONFIG_NXTK_DEFAULT_BORDERCOLORS=y : Default border colors
|
||||
CONFIG_NXFONTS_CHARBITS=7 : 7-bit fonts
|
||||
CONFIG_NXFONT_SANS17X23B=y : Pick a font (any that will fit)
|
||||
|
||||
* The hardware is write only, but the driver maintains a frame buffer
|
||||
to support read and read-write-modiry operations on the LCD.
|
||||
Reading from the frame buffer is, however, untested.
|
||||
|
||||
Then, in order to use the OLED, you will need to build some kind of
|
||||
graphics application or use one of the NuttX graphics examples.
|
||||
Here, for example, is the setup for the graphic "Hello, World!"
|
||||
example:
|
||||
|
||||
CONFIG_EXAMPLES_NXHELLO=y : Enables the example
|
||||
CONFIG_EXAMPLES_NXHELLO_DEFAULT_COLORS=y : Use default colors (see below *)
|
||||
CONFIG_EXAMPLES_NXHELLO_DEFAULT_FONT=y : Use the default font
|
||||
CONFIG_EXAMPLES_NXHELLO_BPP=1 : One bit per pixel
|
||||
CONFIG_EXAMPLES_NXHELLO_EXTERNINIT=y : Special initialization is required.
|
||||
|
||||
* The OLED is monochrome so the only "colors" are black and white.
|
||||
The default "colors" will give you while text on a black background.
|
||||
You can override the faults it you want black text on a while background.

/* Overview
|
||||
*
|
||||
* Since there is no high speed crystal, we will run from the OSC16M clock
|
||||
* source.
|
||||
* We will use its default, POR frequency of 4MHz to avoid an additional
|
||||
* clock switch.
|
||||
*
|
||||
* OSC16M Output = 4MHz
|
||||
* `- GCLK1 Input = 4MHz Prescaler = 1 output = 4MHz
|
||||
* `- DFLL Input = 4MHz Multiplier = 12 output = 48MHz
|
||||
* `- GCLK0 Input = 48MHz Prescaler = 1 output = 48MHz
|
||||
* `- MCLK Input = 48Mhz CPU divider = 1 CPU frequency = 48MHz
|
||||
* APBA divider = 1 APBA frequency = 48MHz
|
||||
* APBB divider = 1 APBB frequency = 48MHz
|
||||
* APBC divider = 1 APBC frequency = 48MHz
|
||||
* APBD divider = 1 APBD frequency = 48MHz
|
||||
* APBE divider = 1 APBE frequency = 48MHz
|
||||
*
|
||||
* The SAML21 Xplained Pro has one on-board crystal:
|
||||
*
|
||||
* XC101 32.768KHz XOSC32
|
||||
*
|
||||
* REVISIT: Not currently used, may want to use as GCLK1 source with
|
||||
* DFLL multiplier of ((48000000+16384)/32768) = 1465 which would yield
|
||||
* a clock of 48,005,120 MHz.

* Description:

* (non-standard) boardctl() interface using the command BOARDIOC_INIT.

*

* Input Parameters:
|
||||
* arg - The boardctl() argument is passed to the board_app_initialize()
|

* implementation without modification. The argument has no
|
||||
* meaning to NuttX; the meaning of the argument is a contract
|
||||
* between the board-specific initialization logic and the
|
||||
* matching application logic. The value could be such things as a
|
||||
* mode enumeration value, a set of DIP switch switch settings, a
|
||||
* pointer to configuration data read from a file or serial FLASH,
|
||||
* or whatever you would like to do with it. Every implementation
|
||||
* should accept zero/NULL as a default configuration.
|
||||
*
|
||||
* Returned Value:
|
||||
* Zero (OK) is returned on success; a negated errno value is returned on
|
||||
* any failure to indicate the nature of the failure.

* Where [n] is the SERCOM number for the SPI module.
|

*
|

* To use this common SPI logic on your board:
|

*
|
||||
* 1. Provide logic in sam_boardinitialize() to configure SPI chip select

* pins.
|
||||
* 2. Provide sam_spi[n]select() and sam_spi[n]status() functions in your

||||
* board-specific logic. These functions will perform chip selection
|
||||
* and status operations using GPIOs in the way your board is
|
||||
* configured.
|
||||
* 2. If CONFIG_SPI_CMDDATA is defined in the NuttX configuration, provide
|
||||
* sam_spi[n]cmddata() functions in your board-specific logic. This
|
||||
* function will perform cmd/data selection operations using GPIOs in
|
||||
* the way your board is configured.
|
||||
* 3. Add a call to sam_spibus_initialize() in your low level application
|
||||
* initialization logic
|
||||
* 4. The handle returned by sam_spibus_initialize() may then be used to
|
||||
* bind the SPI driver to higher level logic (e.g., calling
|
||||
* mmcsd_spislotinitialize(), for example, will bind the SPI driver to

* the SPI MMC/SD driver).

* An alternative way to program the PIO chip select pins is as a normal

/* LEDs: There are three LEDs on board the SAML21 Xplained Pro board:

* The EDBG controls two of the LEDs, a power LED and a status LED.

* There is only one user controllable LED, a yellow LED labelled STATIS
|

* near the SAML21 USB connector.
|

*
|

* This LED is controlled by PB10 and the LED can be activated by driving
|

* PB10 to GND.
|

*
|

STATUS
|

======
|
||||
|
||||
2018-07-26: The basic port was merged into master. It is still
|
||||
incomplete and untested.
|
||||
|
||||
2018-07-29: Code complete. Clock configuration complete. Unverified
|
||||
SERCOM USART, SPI, I2C, Port configuration, and DMA support have been
|
||||
added. I still have no hardware in hand to test.
|
||||
|
||||
2018-07-20: Brought in the USB driver from the SAML21. It is the same
|
||||
USB IP with only small differences. There a a few, small open issues
|
||||
still to be resolved.
|
||||
|
||||
2018-08-01: Hardware in hand. Initial attempts to program the board
|
||||
using a Segger J-Link connected via SWD were unsuccessful because the
|
||||
Metro M4 comes with an application in FLASH and the FLASH locked. See
|
||||
"Unlocking FLASH with J-Link Commander" below. After unlocking the
|
||||
FLASH, I was able to successfully write the NuttX image.
|
||||
|
||||
Unfortunately, the board seems to have become unusable after the first
|
||||
NuttX image was written to FLASH. I am unable to connect the JTAG
|
||||
debugger. The primary JTAG problem seems to be that it is now unable
|
||||
to halt the CPU.
|
||||
|
||||
Future me: This boot-up failure was do to bad clock initialization
|
||||
logic that caused infinite loops during clock configuration. Unlocking
|
||||
and erasing the FLASH is innocuous, but the JTAG will apparently not
|
||||
work if the clocks are not in a good state.
|
||||
|
||||
I would say that as a general practice, any changes to the clock
|
||||
configuration should be testing in SRAM first before risking the
|
||||
write to FLASH.
|
||||
|
||||
2018-08-03: Added a configuration option to run out of SRAM vs FLASH.
|
||||
This is a safer way to do the initial board bring-up since it does
|
||||
not modify the FLASH image nor does it require unlocking the FLASH
|
||||
pages.
|
||||
|
||||
2018-08-31: I finally have a new Metro M4 and have successfully
|
||||
debugged from SRAM (with FLASH unlocked and erased). Several
|
||||
errors in clock configuration logic have been corrected and it now
|
||||
gets through clock configuration okay. It now hangs in the low-level
|
||||
USART initialization.
|
||||
|
||||
It hangs trying to enabled the SERCOM slow clock channel. The clock
|
||||
sequence is:
|
||||
|
||||
1. 32.678KHz crystal -> XOSC32K
|
||||
This is configured and says that XOSC32K is ready.
|
||||
2. XOSCK32 -> GCLK3.
|
||||
This is configured and it says that is is ready (GENEN=1).
|
||||
3. GCLK3 ->SERCOM slow clock channel.
|
||||
This hangs when I try to enable the peripheral clock.
|
||||
|
||||
2018-09-01: I found a workaround by substituting OSCULP32K for XOSC32
|
||||
as the source to GCLK3. With that workaround, the port gets past all
|
||||
clock and USART configuration. A new configuration option was added,
|
||||
CONFIG_METRO_M4_32KHZXTAL. By default this workaround is in place.
|
||||
But you can enable CONFIG_METRO_M4_32KHZXTAL if you want to further
|
||||
study the XOSC32K problem.
|
||||
|
||||
With that workaround (and a bunch of other fixes), the basic NSH
|
||||
configuration appears fully function, indicating the the board bring-
|
||||
up is complete.
|
||||
|
||||
There are additional drivers ported from SAML21 which has, in most cases,
|
||||
identical peripherals. None of these drivers have been verified on the
|
||||
SAMD51, However. These include: DMAC, I2C, SPI, and USB.
|
||||
|
||||
WARNING: If you decide to invest the time to discover whey the XOSC32K
|
||||
clock source is not working, be certain to use the SRAM configuration.
|
||||
That configuration in FLASH is most likely lock up your board irrecoverably
|
||||
is there are any start-up errors!
|
||||
|
||||
Unlocking FLASH
|
||||
===============
|
||||
|
||||
Options
|
||||
-------
|
||||
The Adafruit Metro M4 comes with a very nice bootloader resident in FLASH.
|
||||
so we have two options:
|
||||
|
||||
1. Learn to play well with others. Make NuttX coexist and work in the
|
||||
memory partition available to it. Or,
|
||||
2. Be greedy, unlock the FLASH and overwrite the bootloader.
|
||||
|
||||
I chose to do the last one. I used a Segger J-Link and here are the steps
|
||||
that I took. You can probably do these things in Atmel Studio (?) but for
|
||||
other debug environments, you would have to come up with the solution.
|
||||
|
||||
Unlocking FLASH with J-Link Commander
|
||||
-------------------------------------
|
||||
|
||||
1. Start J-Link Commander:
|
||||
|
||||
SEGGER J-Link Commander V6.32i (Compiled Jul 24 2018 15:20:49)
|
||||
DLL version V6.32i, compiled Jul 24 2018 15:19:55

||||

||||

||||

|
||||
Specify target interface speed [kHz]. <Default>: 4000 kHz

||||

||||

||||
|
||||
|
||||
Connecting to target via SWD

||||

|
||||
Scanning AP map to find all available APs
|
||||
...etc. ...
|
||||
|
||||
2. Look at The NVM "user page" memory at address 0x00804000:
|
||||
|
||||
J-Link>mem8 804000, 10
|
||||
00804000 = 39 92 9A F6 80 FF EC AE FF FF FF FF FF FF FF FF
|
||||
|
||||
The field NVM BOOT (also called BOOTPROT) is the field that locks the
|
||||
lower part of FLASH to support the boot loader. This is bits 26-29
|
||||
of the NVM user page:
|
||||
|
||||
J-Link>mem32 804000, 1
|
||||
00804000 = F69A9239
|
||||
|
||||
In binary 11|11 01|10 1001 1010 1001 0010 0011 1001, so NVM Boot 1101.
|
||||
To unlock the FLASH memory reserved for the bootloader, we need to
|
||||
change this field to 111 so that:
|
||||
|
||||
11|11 11|10 10|01 1010 1001 0010 0011 1001 = F7da9239, or
|
||||
00804000 = 39 92 9A FE 80 FF EC AE FF FF FF FF FF FF FF FF
|
||||
|
||||
is read.
|
||||
|
||||
3. Modify the NVM "user page"
|
||||
|
||||
I did this using the instructions for the SAMD21 found at
|
||||
|
||||
https://roamingthings.de/use-j-link-to-change-the-boot-loader-protection-of-a-sam-d21/
|
||||
|
||||
We will need to create a small Motorola S-REC file to write new values
|
||||
into NVM. See https://en.m.wikipedia.org/wiki/SREC_(file_format) for a
|
||||
description of the Motorola SREC format.
|
||||
|
||||
I wrote a small program at boards/arm/samd5e5/metro-m4-scripts/nvm.c that will
|
||||
generate this Motorola SREC file with the correct checksum. The file at
|
||||
boards/arm/samd5e5/metro-m4-scripts/nvm.c is the output of that program.

||||

||||

|
||||
You will, of course, have to change the path as appropriate for your system.
|

Serial Console
|
||||
==============
|
||||
|
||||
An Arduino compatible serial Shield is assumed (or equivalently, and
|
||||
external RS-232 or serial-to-USB adapter connected on Arduino pins D0 and
|
||||
D1):

LEDs
|
||||
====
|
||||
|
||||
The Adafruit Metro M4 has four LEDs, but only two are controllable by software:
|
||||
|
||||
1. The red LED on the Arduino D13 pin, and
|
||||
2. A NeoPixel RGB LED.
|
||||
|
||||
Currently, only the red LED is supported.

Run from SRAM
|
||||
=============
|
||||
|
||||
I bricked my first Metro M4 board because there were problems in the
|
||||
bring-up logic. These problems left the chip in a bad state that was
|
||||
repeated on each reset because the code was written into FLASH and I was
|
||||
unable to ever connect to it again via SWD.
|
||||
|
||||
To make the bring-up less risky, I added a configuration option to build
|
||||
the code to execution entirely out of SRAM. By default, the setting
|
||||
CONFIG_METRO_M4_RUNFROMFLASH=y is used and the code is built to run out of
|
||||
FLASH. If CONFIG_METRO_M4_RUNFROMSRAM=y is selected instead, then the
|
||||
code is built to run out of SRAM.
|
||||
|
||||
To use the code in this configuration, the program must be started a
|
||||
little differently:
|
||||
|
||||
gdb> mon reset
|
||||
gdb> mon halt
|
||||
gdb> load nuttx << Load NuttX into SRAM
|
||||
gdb> file nuttx << Assuming debug symbols are enabled
|
||||
gdb> mon memu32 0x20000000 << Get the address of initial stack
|
||||
gdb> mon reg sp 0x200161c4 << Set the initial stack pointer using this address
|
||||
gdb> mon memu32 0x20000004 << Get the address of __start entry point
|
||||
gdb> mon reg pc 0x20000264 << Set the PC using this address (without bit 0 set)
|
||||
gdb> si << Step in just to make sure everything is okay
|
||||
gdb> [ set breakpoints ]
|
||||
gdb> c << Then continue until you hit a breakpoint
|
||||
|
||||
Where 0x200161c4 and 0x20000264 are the values of the initial stack and
|
||||
the __start entry point that I read from SRAM
|
||||
|
||||
Configurations
|
||||
==============
|
||||
|
||||
Each Adafruit Metro M4 configuration is maintained in a sub-directory and
|
||||
can be selected as follow:
|
||||
|
||||
tools/configure.sh [OPTIONS] metro-m4:<subdir>
|
||||
|
||||
Do 'tools/configure.sh -h' for the list of options. If you are building
|
||||
under Windows with Cygwin, you would need the -c option, for example.
|
||||
|
||||
Before building, make sure that the PATH environmental variable includes the
|
||||
correct path to the directory than holds your toolchain binaries.
|
||||
|
||||
And then build NuttX by simply typing the following. At the conclusion of
|
||||
the make, the nuttx binary will reside in an ELF file called, simply, nuttx.
|
||||
|
||||
make
|
||||
|
||||
The <subdir> that is provided above as an argument to the tools/configure.sh
|
||||
must be is one of configurations listed in the following paragraph.
|
||||
|
||||
NOTES:
|
||||
|
||||
1. These configurations use the mconf-based configuration tool. To
|
||||
change any of these configurations using that tool, you should:
|
||||
|
||||
a. Build and install the kconfig-mconf tool. See nuttx/README.txt
|
||||
see additional README.txt files in the NuttX tools repository.
|
||||
|
||||
b. Execute 'make menuconfig' in nuttx/ in order to start the
|
||||
reconfiguration process.
|
||||
|
||||
2. Unless stated otherwise, all configurations generate console
|
||||
output of on SERCOM3 which is available on a Arduino Serial
|
||||
Shield (see the section "Serial Console" above).
|
||||
|
||||
3. Unless otherwise stated, the configurations are setup build under
|
||||
Linux with a generic ARM EABI toolchain:
|
||||
|
||||
Configuration sub-directories
|
||||
-----------------------------
|
||||
|
||||
nsh:
|
||||
This configuration directory will built the NuttShell. See NOTES ;for
|
||||
common configuration above and the following:
|
||||
|
||||
NOTES:
|
||||
|
||||
1. The CMCC (Cortex M Cache Controller) is enabled.

perhaps it is missing or defective on my board (there is a metal
|

package that could be a crystal on board, but I am not certain).
|

Another, more likely option is that there is a coding error on my
|

part that prevents the 32.768 KHz crystal from usable(?)
|

The configuration defaults to using the always-on OSCULP32 as the

WARNING: If you decide to invest the time to discover whey the XOSC32K
|
||||
clock source is not working, be certain to use the SRAM configuration.
|
||||
That configuration in FLASH is most likely lock up your board irrecoverably
|
||||
is there are any start-up errors!

|

Serial Console
|
||||
==============
|
||||
|
||||
The onboard debugger on the SAME54 Xplained Pro provides a virtual serial
|
||||
interface over the DEBUG USB port. The pins on the SAME54 are as follows:

PC18 GPIO output
|
||||
|
||||
Run from SRAM
|
||||
=============
|
||||
|
||||
I bricked my first Metro M4 board because there were problems in the
|
||||
bring-up logic. These problems left the chip in a bad state that was
|
||||
repeated on each reset because the code was written into FLASH and I was
|
||||
unable to ever connect to it again via SWD.
|
||||
|
||||
To make the bring-up less risky, I added a configuration option to build
|
||||
the code to execution entirely out of SRAM. By default, the setting
|
||||
CONFIG_SAME54_XPLAINED_PRO_RUNFROMFLASH=y is used and the code is built to run out of
|
||||
FLASH. If CONFIG_SAME54_XPLAINED_PRO_RUNFROMSRAM=y is selected instead, then the
|
||||
code is built to run out of SRAM.
|
||||
|
||||
To use the code in this configuration, the program must be started a
|
||||
little differently:
|
||||
|
||||
gdb> mon reset
|
||||
gdb> mon halt
|
||||
gdb> load nuttx << Load NuttX into SRAM
|
||||
gdb> file nuttx << Assuming debug symbols are enabled
|
||||
gdb> mon memu32 0x20000000 << Get the address of initial stack
|
||||
gdb> mon reg sp 0x200161c4 << Set the initial stack pointer using this address
|
||||
gdb> mon memu32 0x20000004 << Get the address of __start entry point
|
||||
gdb> mon reg pc 0x20000264 << Set the PC using this address (without bit 0 set)
|
||||
gdb> si << Step in just to make sure everything is okay
|
||||
gdb> [ set breakpoints ]
|
||||
gdb> c << Then continue until you hit a breakpoint
|
||||
|
||||
Where 0x200161c4 and 0x20000264 are the values of the initial stack and
|
||||
the __start entry point that I read from SRAM
|
||||
|
||||
Configurations
|
||||
==============
|
||||
|
||||
Each SAME54 Xplained Pro configuration is maintained in a sub-directory and
|
||||
can be selected as follow:
|
||||
|
||||
tools/configure.sh [OPTIONS] same54-xplained-pro:<subdir>
|
||||
|
||||
Do 'tools/configure.sh -h' for the list of options. If you are building
|
||||
under Windows with Cygwin, you would need the -c option, for example.
|
||||
|
||||
Before building, make sure that the PATH environmental variable includes the
|
||||
correct path to the directory than holds your toolchain binaries.
|
||||
|
||||
And then build NuttX by simply typing the following. At the conclusion of
|
||||
the make, the nuttx binary will reside in an ELF file called, simply, nuttx.
|
||||
|
||||
make
|
||||
|
||||
The <subdir> that is provided above as an argument to the tools/configure.sh
|
||||
must be is one of configurations listed in the following paragraph.
|
||||
|
||||
NOTES:
|
||||
|
||||
1. These configurations use the mconf-based configuration tool. To
|
||||
change any of these configurations using that tool, you should:
|
||||
|
||||
a. Build and install the kconfig-mconf tool. See nuttx/README.txt
|
||||
see additional README.txt files in the NuttX tools repository.
|
||||
|
||||
b. Execute 'make menuconfig' in nuttx/ in order to start the
|
||||
reconfiguration process.
|
||||
|
||||
2. Unless stated otherwise, all configurations generate console
|
||||
output on SERCOM2 which is available via USB debug.
|
||||
|
||||
3. Unless otherwise stated, the configurations are setup build under
|
||||
Linux with a generic ARM EABI toolchain:
|
||||
|
||||
Configuration sub-directories
|
||||
-----------------------------
|
||||
|
||||
nsh:
|
||||
This configuration directory will built the NuttShell. See NOTES for
|
||||
common configuration above and the following:
|
||||
|
||||
NOTES:
|
||||
|
||||
1. The CMCC (Cortex M Cache Controller) is enabled.

/* Overview
|
||||
*
|
||||
* Per the schematic Adafruit Metro M4 Pro has one on-board crystal:
|
||||
*
|
||||
* X4 32.768KHz XOSC32
|
||||
*
|
||||
* However, I have been unsuccessful using it and have fallen back to using
|
||||
* OSCULP32K(Unless CONFIG_SAME54_XPLAINED_PRO_32KHZXTAL=y)
|
||||
*
|
||||
* Since there is no high speed crystal, we will run from the OSC16M clock
|
||||
* source.
|
||||
*
|
||||
* OSC48M Output = 48Mhz
|
||||
* |
|
||||
* FDLL Input = 48MHz
|
||||
* | Output = 48MHz
|
||||
* GCLK5 Input = 48MHz
|
||||
* | Output = 2MHz
|
||||
* DPLL0 Input = 2MHz
|
||||
* | Output = 120MHz
|
||||
* GCLK0 Input = 120MHz
|
||||
* | Output = 120MHz
|

* MCK Input = 120MHz
|
