Development Environment
|
||||
=======================
|
||||
|
||||
Either Linux or Cygwin under 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.
|
||||
|
||||
GNU Toolchain Options
|
||||
=====================
|
||||
|
||||
As of this writing, all testing has been performed using the NuttX buildroot
|
||||
toolchain described below. I have also verified the build using the
|
||||
CodeSourcery GCC toolchain for windows. Most any contemporary EABI GCC
|
||||
toolchain should work will a little tinkering.
|
||||
|
||||
NuttX 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 freedom-kl25z:<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
|
||||
====
|
||||
|
||||
The Freedom KL25Z has a single RGB LED driven by the KL25Z as follows:
|
||||
|
||||
------------- --------
|
||||
RGB LED KL25Z128
|
||||
------------- --------
|
||||
Red Cathode PTB18
|
||||
Green Cathode PTB19
|
||||
Blue Cathode PTD1
|
||||
|
||||
NOTE: PTD1 is also connected to the I/O header on J2 pin 10 (also known as D13).
|
||||
|
||||
If CONFIG_ARCH_LEDs is defined, then NuttX will control the LED on board the
|
||||
Freedom KL25Z. The following definitions describe how NuttX controls the LEDs:
|
||||
|
||||
SYMBOL Meaning LED state
|
||||
Initially all LED is OFF
|
||||
------------------- ----------------------- --------------------------
|
||||
LED_STARTED NuttX has been started R=OFF G=OFF B=OFF
|
||||
LED_HEAPALLOCATE Heap has been allocated (no change)
|
||||
LED_IRQSENABLED Interrupts enabled (no change)
|
||||
LED_STACKCREATED Idle stack created R=OFF G=OFF B=ON
|
||||
LED_INIRQ In an interrupt (no change)
|
||||
LED_SIGNAL In a signal handler (no change)
|
||||
LED_ASSERTION An assertion failed (no change)
|
||||
LED_PANIC The system has crashed R=FLASHING G=OFF B=OFF
|
||||
LED_IDLE K25Z1XX is in sleep mode (Optional, not used)
|
||||
|
||||
Serial Console
|
||||
==============
|
||||
|
||||
As with most NuttX configurations, the Freedom KL25Z configurations
|
||||
depend on having a serial console to interact with the software. The
|
||||
Freedom KL25Z, however, has no on-board RS-232 drivers so will be
|
||||
necessary to connect the Freedom KL25Z UART pins to an external
|
||||
RS-232 driver board or TTL-to-Serial USB adaptor.
|
||||
|
||||
By default UART0 is used as the serial console on this boards. The UART0
|
||||
is configured to work with the OpenSDA USB CDC/ACM port:
|
||||
|
||||
------ ------------------------------- -----------------------------
|
||||
PIN PIN FUNCTIONS BOARD SIGNALS
|
||||
------ ------------------------------- -----------------------------
|
||||
Pin 27 PTA1/TSI0_CH2/UART0_RX/FTM2_CH0 UART1_RX_TGTMCU and D0 (PTA1)
|
||||
Pin 28 PTA2/TSI0_CH3/UART0_TX/FTM2_CH1 UART1_TX_TGTMCU and D1 (PTA2)
|
||||
|
||||
But the UART0 Tx/Rx signals are also available on J1:
|
||||
|
||||
---------------- ---------
|
||||
UART0 SIGNAL J1 pin
|
||||
---------------- ---------
|
||||
UART0_RX (PTA1) J1, pin 2
|
||||
UART0_TX (PTA2) J1, pin 4
|
||||
|
||||
Ground is available on J2 pin 14. 3.3V is available on J3 and J4.
|
||||
|
||||
mbed
|
||||
====
|
||||
|
||||
The Freedom KL25Z includes a built-in SDA debugger. An alternative
|
||||
to the SDA bootloader is this boot loader from mbed:
|
||||
|
||||
http://mbed.org/handbook/mbed-FRDM-KL25Z-Getting-Started
|
||||
http://mbed.org/handbook/Firmware-FRDM-KL25Z
|
||||
|
||||
Using the mbed loader:
|
||||
|
||||
1. Connect the KL25Z to the host PC using the USB connector labeled
|
||||
SDA.
|
||||
2. A new file system will appear called MBED; open it with Windows
|
||||
Explorer (assuming that you are using Windows).
|
||||
3. Drag and drop nuttx.bin into the MBED window. This will load the
|
||||
nuttx.bin binary into the KL25Z. The MBED window will close
|
||||
then re-open and the KL25Z will be running the new code.
|
||||
|
||||
Using the Freescale SDA debugger is essentially the same. That
|
||||
debugger will also accept .hex file.
|
||||
|
||||

Configurations
|
||||
==============
|
||||
|
||||
Each FREEDOM-KL25Z configuration is maintained in a sub-directory and
|
||||
can be selected as follow:
|
||||
|
||||
tools/configure.sh freedom-kl25z:<subdir>
|
||||
|
||||
If this is a Windows native build, then configure.bat should be used
|
||||
instead of configure.sh:
|
||||
|
||||
configure.bat freedom-kl25z\<subdir>
|
||||
|
||||
Where <subdir> is one of the following:
|
||||
|
||||
nsh:
|
||||
---
|
||||
Configures the NuttShell (nsh) located at apps/examples/nsh. The
|
||||
Configuration enables the serial interface on UART0. Support for
|
||||
builtin applications is disabled.
|
||||
|
||||
NOTES:
|
||||
|
||||
1. This configuration uses the mconf-based configuration tool. To
|
||||
change this configuration 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. By default, this configuration uses the ARM EABI toolchain
|
||||
for Windows and builds under Cygwin (or probably MSYS). That
|
||||
can easily be reconfigured, of course.
|
||||
|
||||
CONFIG_HOST_WINDOWS=y : Builds under Windows
|
||||
CONFIG_WINDOWS_CYGWIN=y : Using Cygwin
|
||||
CONFIG_ARMV7M_TOOLCHAIN_GNU_EABIW=y : GNU EABI toolchain for Windows
|
||||
|
||||
3. Serial Console. A serial console is necessary to interrupt with
|
||||
NSH. The serial console is configured on UART0 which is available
|
||||
on J1:
|
||||
|
||||
---------------- ---------
|
||||
UART0 SIGNAL J1 pin
|
||||
---------------- ---------
|
||||
UART0_RX (PTA1) J1, pin 2
|
||||
UART0_TX (PTA2) J1, pin 4
|
||||
|
||||
Ground is available on J2 pin 14. 3.3V is available on J3 and J4.
|
||||
|
||||
It is possible to configure NSH to use a USB serial console instead
|
||||
of an RS-232 serial console. However, that configuration has not
|
||||
been impelmented as of this writing.
|
||||
|
||||
4. Memory Usage. The size command gives us the static memory usage.
|
||||
This is what I get:
|
||||
|
||||
$ size nuttx
|
||||
text data bss dec hex filename
|
||||
35037 106 1092 36235 8d8b nuttx
|
||||
|
||||
And we can get the runtime memory usage from the NSH free command:
|
||||
|
||||
NuttShell (NSH) NuttX-6.25
|
||||
nsh> free
|
||||
total used free largest
|
||||
Mem: 14160 3944 10216 10216
|
||||
nsh>
|
||||
|
||||
Summary:
|
||||
|
||||
- This slightly tuned NSH example uses 34.2KB of FLASH leaving 93.8KB
|
||||
of FLASH (72%) free from additional application development.
|
||||
|
||||
I did not do all of the arithmetic, but it appears to me that of this
|
||||
34+KB of FLASH usage, probably 20-30% of the FLASH is used by libgcc!
|
||||
libgcc has gotten very fat!
|
||||
|
||||
- Static SRAM usage is about 1.2KB (<4%).
|
||||
|
||||
- At run time, 10.0KB of SRAM (62%) is still available for additional
|
||||
applications. Most of the memory used at runtime is allocated I/O
|
||||
buffers and the stack for the NSH main thread (1.5KB).
|
||||
|
||||
There is probably enough free memory to support 3 or 4 application
|
||||
threads in addition to NSH.
|
||||
|
||||
5. This configurations has support for NSH built-in applications. However,
|
||||
in the default configuration no built-in applications are enabled.

*
|

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

* pins.
|
||||
* 2. Provide kl_spi[n]select() and kl_spi[n]status() functions

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

* 2. If CONFIG_SPI_CMDDATA is defined in the NuttX configuration, provide

* kl_spi[n]cmddata() functions in your board-specific logic. These
|
||||
* functions will perform cmd/data selection operations using GPIOs in
|

* the way your board is configured.
|
||||
* 3. Add a call to kl_spibus_initialize() in your low level application
|
||||
* initialization logic
|
||||
* 4. The handle returned by kl_spibus_initialize() may then be used to
|
||||
* bind the SPI driver to higher level logic (e.g., calling

Development Environment
|
||||
=======================
|
||||
|
||||
Either Linux or Cygwin under 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.
|
||||
|
||||
GNU Toolchain Options
|
||||
=====================
|
||||
|
||||
As of this writing, all testing has been performed using the NuttX buildroot
|
||||
toolchain described below. I have also verified the build using the
|
||||
CodeSourcery GCC toolchain for windows. Most any contemporary EABI GCC
|
||||
toolchain should work will a little tinkering.
|
||||
|
||||
NuttX 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 freedom-kl26z:<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
|
||||
====
|
||||
|
||||
The Freedom KL26Z has a single RGB LED driven by the KL26Z as follows:
|
||||
|
||||
------------- --------
|
||||
RGB LED KL26Z128
|
||||
------------- --------
|
||||
Red Cathode PTE29
|
||||
Green Cathode PTE31
|
||||
Blue Cathode PTD5
|
||||
|
||||
NOTE: PTD5 is also connected to the I/O header on J2 pin 12 (also known as D13).
|
||||
|
||||
If CONFIG_ARCH_LEDs is defined, then NuttX will control the LED on board the
|
||||
Freedom KL26Z. The following definitions describe how NuttX controls the LEDs:
|
||||
|
||||
SYMBOL Meaning LED state
|
||||
Initially all LED is OFF
|
||||
------------------- ----------------------- --------------------------
|
||||
LED_STARTED NuttX has been started R=OFF G=OFF B=OFF
|
||||
LED_HEAPALLOCATE Heap has been allocated (no change)
|
||||
LED_IRQSENABLED Interrupts enabled (no change)
|
||||
LED_STACKCREATED Idle stack created R=OFF G=OFF B=ON
|
||||
LED_INIRQ In an interrupt (no change)
|
||||
LED_SIGNAL In a signal handler (no change)
|
||||
LED_ASSERTION An assertion failed (no change)
|
||||
LED_PANIC The system has crashed R=FLASHING G=OFF B=OFF
|
||||
LED_IDLE K26Z1XX is in sleep mode (Optional, not used)
|
||||
|
||||
Serial Console
|
||||
==============
|
||||
|
||||
As with most NuttX configurations, the Freedom KL26Z configurations
|
||||
depend on having a serial console to interact with the software. The
|
||||
Freedom KL26Z, however, has no on-board RS-232 drivers so will be
|
||||
necessary to connect the Freedom KL26Z UART pins to an external
|
||||
RS-232 driver board or TTL-to-Serial USB adaptor.
|
||||
|
||||
By default UART0 is used as the serial console on this boards. The UART0
|
||||
is configured to work with the OpenSDA USB CDC/ACM port:
|
||||
|
||||
------ ------------------------------- -----------------------------
|
||||
PIN PIN FUNCTIONS BOARD SIGNALS
|
||||
------ ------------------------------- -----------------------------
|
||||
Pin 27 PTA1/TSI0_CH2/UART0_RX/FTM2_CH0 UART1_RX_TGTMCU and D0 (PTA1)
|
||||
Pin 28 PTA2/TSI0_CH3/UART0_TX/FTM2_CH1 UART1_TX_TGTMCU and D1 (PTA2)
|
||||
|
||||
But the UART0 Tx/Rx signals are also available on J1:
|
||||
|
||||
---------------- ---------
|
||||
UART0 SIGNAL J1 pin
|
||||
---------------- ---------
|
||||
UART0_RX (PTA1) J1, pin 2
|
||||
UART0_TX (PTA2) J1, pin 4
|
||||
|
||||
Ground is available on J2 pin 14. 3.3V is available on J3 and J4.
|
||||
|
||||

Configurations
|
||||
==============
|
||||
|
||||
Each FREEDOM-KL26Z configuration is maintained in a sub-directory and
|
||||
can be selected as follow:
|
||||
|
||||
tools/configure.sh freedom-kl26z:<subdir>
|
||||
|
||||
If this is a Windows native build, then configure.bat should be used
|
||||
instead of configure.sh:
|
||||
|
||||
configure.bat freedom-kl26z\<subdir>
|
||||
|
||||
Where <subdir> is one of the following:
|
||||
|
||||
nsh:
|
||||
---
|
||||
Configures the NuttShell (nsh) located at apps/examples/nsh. The
|
||||
Configuration enables the serial interface on UART0. Support for
|
||||
builtin applications is disabled.
|
||||
|
||||
NOTES:
|
||||
|
||||
1. This configuration uses the mconf-based configuration tool. To
|
||||
change this configuration 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. By default, this configuration uses the ARM EABI toolchain
|
||||
for Windows and builds under Cygwin (or probably MSYS). That
|
||||
can easily be reconfigured, of course.
|
||||
|
||||
CONFIG_HOST_WINDOWS=y : Builds under Windows
|
||||
CONFIG_WINDOWS_CYGWIN=y : Using Cygwin
|
||||
CONFIG_ARMV7M_TOOLCHAIN_GNU_EABIW=y : GNU EABI toolchain for Windows
|
||||
|
||||
3. Serial Console. A serial console is necessary to interrupt with
|
||||
NSH. The serial console is configured on UART0 which is available
|
||||
on J1:
|
||||
|
||||
---------------- ---------
|
||||
UART0 SIGNAL J1 pin
|
||||
---------------- ---------
|
||||
UART0_RX (PTA1) J1, pin 2
|
||||
UART0_TX (PTA2) J1, pin 4
|
||||
|
||||
Ground is available on J2 pin 14. 3.3V is available on J3 and J4.
|
||||
|
||||
It is possible to configure NSH to use a USB serial console instead
|
||||
of an RS-232 serial console. However, that configuration has not
|
||||
been impelmented as of this writing.
|
||||
|
||||
4. Memory Usage. The size command gives us the static memory usage.
|
||||
This is what I get:
|
||||
|
||||
$ size nuttx
|
||||
text data bss dec hex filename
|
||||
35037 106 1092 36235 8d8b nuttx
|
||||
|
||||
And we can get the runtime memory usage from the NSH free command:
|
||||
|
||||
NuttShell (NSH) NuttX-6.25
|
||||
nsh> free
|
||||
total used free largest
|
||||
Mem: 14160 3944 10216 10216
|
||||
nsh>
|
||||
|
||||
Summary:
|
||||
|
||||
- This slightly tuned NSH example uses 34.2KB of FLASH leaving 93.8KB
|
||||
of FLASH (72%) free from additional application development.
|
||||
|
||||
I did not do all of the arithmetic, but it appears to me that of this
|
||||
34+KB of FLASH usage, probably 20-30% of the FLASH is used by libgcc!
|
||||
libgcc has gotten very fat!
|
||||
|
||||
- Static SRAM usage is about 1.2KB (<4%).
|
||||
|
||||
- At run time, 10.0KB of SRAM (62%) is still available for additional
|
||||
applications. Most of the memory used at runtime is allocated I/O
|
||||
buffers and the stack for the NSH main thread (1.5KB).
|
||||
|
||||
There is probably enough free memory to support 3 or 4 application
|
||||
threads in addition to NSH.
|
||||
|
||||
5. This configurations has support for NSH built-in applications. However,
|
||||
in the default configuration no built-in applications are enabled.

*
|

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

* pins.
|
||||
* 2. Provide kl_spi[n]select() and kl_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

* 2. If CONFIG_SPI_CMDDATA is defined in the NuttX configuration, provide

* kl_spi[n]cmddata() functions in your board-specific logic. These
|
||||
* functions will perform cmd/data selection operations using GPIOs in
|
||||
* the way your board is configured.
|
||||
* 3. Add a call to kl_spibus_initialize() in your low level application
|
||||
* initialization logic
|
||||
* 4. The handle returned by kl_spibus_initialize() may then be used to
|
||||
* bind the SPI driver to higher level logic (e.g., calling

* PIO chip select pins may be programmed by the board specific logic in

|

*
|

* 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

Teensy LC README
|
||||
================
|
||||
|
||||
This is the README file for NuttX on the PJRC Teensy LC. The Teensy LC
|
||||
is a DIP style breakout board for the MKL25Z64 and comes with a USB
|
||||
based bootloader. Contributed by Michael Hope.
|
||||
|
||||
Development Environment
|
||||
=======================
|
||||
|
||||
All testing was done with the GNU ARM Embedded 4.9 toolchain on
|
||||
Linux. See https://developer.arm.com/open-source/gnu-toolchain/gnu-rm to download.
|
||||
|
||||
Once you've configured and built NuttX, flash the resulting
|
||||
nuttx.hex file to the board using the Teensy Loader Application.
|
||||
|
||||
LEDs
|
||||
====
|
||||
|
||||
The Teensy LC has a single LED. If CONFIG_ARCH_LEDS is defined, then
|
||||
NuttX will update the LED as the board boots. The summary is:
|
||||
|
||||
* LED off: board booting
|
||||
* LED on: initial stack created
|
||||
* LED flashing: panic.
|
||||
|
||||
See `include/board.h` for details.
|
||||
|
||||
Serial Console
|
||||
==============
|
||||
|
||||
The serial console is mapped to UART0 and appears on pins 0 (RX) and
|
||||
1 (TX). Consider using a 3.3 V USB to serial adapter such as the
|
||||
Sparkfun #9717 FTDI cable.

*

* 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.

|

*
|
||||
* 1. Provide logic in kl_boardinitialize() to configure SPI chip select
|
||||
* pins.
|
||||
* 2. Provide kl_spi[n]select() and kl_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
|

* kl_spi[n]cmddata() functions in your board-specific logic. These
|
||||
* functions will perform cmd/data selection operations using GPIOs in
|
||||
* the way your board is configured.
|
||||
* 3. Add a call to kl_spibus_initialize() in your low level application
|
||||
* initialization logic
|
||||
* 4. The handle returned by kl_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

* PIO chip select pins may be programmed by the board specific logic in

|

*
|

* 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
