README
|
||||
^^^^^
|
||||
|
||||
This is the README file for the port of NuttX to the Micropendous 3 board.
|
||||
This board is develepmend by http://code.google.com/p/opendous/. The
|
||||
Micropendous 3 is based on an Atmel AT90USB646, 647, 1286 or 1287 MCU.
|
||||
NuttX was ported using the AT90USB647 version. As of this writing,
|
||||
documentation for the Micropendous board is available here:

DFU Bootloader
|
||||
^^^^^^^^^^^^^^
|
||||
|
||||
There is also an DFU bootloader that resides in the upper 8Kb of FLASH
|
||||
(unless you ERASE the flash with ICE). You can enter this bootloader
|
||||
(if it is in FLASH) by:
|
||||
|
||||
Holding both the SW1 (RESET) and SW2, then releasing SW1 while continuing
|
||||
to hold SW2. SW2 connects to the PE2/HWB signal and causes a reset into
|
||||
the bootloader memory region.
|
||||
|
||||
Then you can use FLIP to load code into FLASH (available at the Atmel Web
|
||||
Site). The DFU USB driver for the DFU bootload is available in the usb
|
||||
subdirectory in the FLIP installation location.
|
||||
|
||||
Serial Console
|
||||
^^^^^^^^^^^^^^
|
||||
|
||||
A serial console is supported on an external MAX232/MAX3232 Connected
|
||||
on PD2 and PD3:
|
||||
|
||||
Port D, Bit 2: RXD1, Receive Data (Data input pin for the USART1). When
|
||||
the USART1 receiver is enabled this pin is configured as an input
|
||||
regardless of the value of DDD2. When the USART forces this pin to
|
||||
be an input, the pull-up can still be controlled by the PORTD2 bit.
|
||||
Port D, Bit 3: TXD1, Transmit Data (Data output pin for the USART1).
|
||||
When the USART1 Transmitter is enabled, this pin is configured as
|
||||
an output regardless of the value of DDD3.

Toolchains
|
||||
^^^^^^^^^^
|
||||
|
||||
There are several toolchain options. However, testing has been performed
|
||||
using *only* the NuttX buildroot toolchain described below. Therefore,
|
||||
the NuttX buildroot toolchain is the recommended choice.
|
||||
|
||||
The toolchain may be selected using the kconfig-mconf tool (via 'make menuconfig'),
|
||||
by editing the existing configuration file (defconfig), or by overriding
|
||||
the toolchain on the make commandline with CONFIG_AVR_TOOLCHAIN=<toolchain>.
|
||||
|
||||
The valid values for <toolchain> are BUILDROOT, CROSSPACK, LINUXGCC and WINAVR.
|
||||
|
||||
Buildroot:
|
||||
|
||||
There is a DIY buildroot version for the AVR boards here:
|
||||
http://bitbucket.org/nuttx/buildroot/downloads/. See the
|
||||
following section for details on building this toolchain.
|
||||
|
||||
Before building, make sure that the path to the new toolchain is included
|
||||
in your PATH environment variable.
|
||||
|
||||
After configuring NuttX, make sure that CONFIG_AVR_BUILDROOT_TOOLCHAIN=y is set in your
|
||||
.config file.
|
||||
|
||||
WinAVR:
|
||||
|
||||
For Cygwin development environment on Windows machines, you can use
|
||||
WinAVR: http://sourceforge.net/projects/winavr/files/
|
||||
|
||||
Before building, make sure that the path to the new toolchain is included
|
||||
in your PATH environment variable.
|
||||
|
||||
After configuring NuttX, make sure that CONFIG_AVR_WINAVR_TOOLCHAIN=y is set in your
|
||||
.config file.
|
||||
|
||||
WARNING: There is an incompatible version of cygwin.dll in the WinAVR/bin
|
||||
directory! Make sure that the path to the correct cygwin.dll file precedes
|
||||
the path to the WinAVR binaries!
|
||||
|
||||
Linux:
|
||||
|
||||
For Linux, there are widely available avr-gcc packages. On Ubuntu, use:
|
||||
sudo apt-get install gcc-avr gdb-avr avr-libc
|
||||
|
||||
After configuring NuttX, make sure that CONFIG_AVR_LINUXGCC_TOOLCHAIN=y is set in your
|
||||
.config file.
|
||||
|
||||
macOS:
|
||||
|
||||
For macOS, the CrossPack for AVR toolchain is available from:
|
||||
|
||||
http://www.obdev.at/products/crosspack/index.html
|
||||
|
||||
This toolchain is functionally equivalent to the Linux GCC toolchain.
|
||||
|
||||
Windows Native Toolchains
|
||||
^^^^^^^^^^^^^^^^^^^^^^^^^
|
||||
|
||||
The WinAVR toolchain is a Windows native toolchain. There are several
|
||||
limitations to using a Windows native toolchain 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.
|
||||
|
||||
An additional issue with the WinAVR toolchain, in particular, is that it
|
||||
contains an incompatible version of the Cygwin DLL in its bin/ directory.
|
||||
You must take care that the correct Cygwin DLL is used.
|
||||
|
||||
NuttX buildroot Toolchain
|
||||
^^^^^^^^^^^^^^^^^^^^^^^^^
|
||||
|
||||
If NuttX buildroot toolchain source tarball cne can be downloaded from the
|
||||
NuttX Bitbucket download site (https://bitbucket.org/nuttx/nuttx/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 micropendous3:<sub-dir>
|
||||
|
||||
NOTE: you also must copy avr-libc header files into the NuttX include
|
||||
directory with command perhaps like:
|
||||
|
||||
cp -a /cygdrive/c/WinAVR/include/avr include/.
|
||||
|
||||
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/avr-defconfig-4.5.2 .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
|
||||
detailed PLUS some special instructions that you will need to follow if you
|
||||
are building a toolchain for Cygwin under Windows.
|
||||
|
||||
avr-libc
|
||||
^^^^^^^^
|
||||
|
||||
Header Files
|
||||
|
||||
In any case, header files from avr-libc are required: http://www.nongnu.org/avr-libc/.
|
||||
A snapshot of avr-lib is included in the WinAVR installation. For Linux
|
||||
development platforms, avr-libc package is readily available (and would
|
||||
be installed in the apt-get command shown above). But if you are using
|
||||
the NuttX buildroot configuration on Cygwin, then you will have to build
|
||||
get avr-libc from binaries.
|
||||
|
||||
Header File Installation
|
||||
|
||||
The NuttX build will required that the AVR header files be available via
|
||||
the NuttX include directory. This can be accomplished by either copying
|
||||
the avr-libc header files into the NuttX include directory:
|
||||
|
||||
cp -a <avr-libc-path>/include/avr <nuttx-path>/include/.
|
||||
|
||||
Or simply using a symbolic link:
|
||||
|
||||
ln -s <avr-libc-path>/include/avr <nuttx-path>/include/.
|
||||
|
||||
Build Notes:
|
||||
|
||||
It may not necessary to have a built version of avr-lib; only header files
|
||||
are required. Bu if you choose to use the optimized libraru functions of
|
||||
the flowing point library, then you may have to build avr-lib from sources.
|
||||
Below are instructions for building avr-lib from fresh sources:
|
||||
|
||||
1. Download the avr-libc package from:
|
||||
|
||||
http://savannah.nongnu.org/projects/avr-libc/
|
||||
|
||||
I am using avr-lib-1.7.1.tar.bz2
|
||||
|
||||
2. Upack the tarball and cd into the
|
||||
|
||||
tar jxf avr-lib-1.7.1.tar.bz2
|
||||
cd avr-lib-1.7.1
|
||||
|
||||
3. Configure avr-lib. Assuming that WinAVR is installed at the following
|
||||
location:
|
||||
|
||||
export PATH=/cygdrive/c/WinAVR/bin:$PATH
|
||||
./configure --build=`./config.guess` --host=avr
|
||||
|
||||
This takes a *long* time.
|
||||
|
||||
4. Make avr-lib.
|
||||
|
||||
make
|
||||
|
||||
This also takes a long time because it generates variants for nearly
|
||||
all AVR chips.
|
||||
|
||||
5. Install avr-lib.
|
||||
|
||||
make install
|
||||
|
||||

Common Configuration Notes
|
||||
--------------------------
|
||||
|
||||
1. Each Micropendous3 configuration is maintained in a sub-directory and
|
||||
can be selected as follow:
|
||||
|
||||
tools/configure.sh micropendous3:<subdir>
|
||||
|
||||
Where <subdir> is one of the configuration sub-directories described in
|
||||
the following paragraph.
|
||||
|
||||
NOTE: You must also copy avr-libc header files, perhaps like:
|
||||
|
||||
cp -a /cygdrive/c/WinAVR/include/avr include/.
|
||||
|
||||
2. These configurations use the mconf-based configuration tool. To
|
||||
change a 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.
|
||||
|
||||
3. By default, all configurations assume the NuttX Buildroot toolchain
|
||||
under Cygwin with Windows. This is easily reconfigured:
|
||||
|
||||
CONFIG_HOST_WINDOWS=y
|
||||
CONFIG_WINDOWS_CYGWIN=y
|
||||
CONFIG_AVR_BUILDROOT_TOOLCHAIN=y

o Download the Teensy application from http://pjrc.com/teensy/loader.html
|
||||
o Instructions are available for your OS at that places as well.
|
||||
|
||||
Summary:
|
||||
|
||||
1. Start Teensy
|
||||
2. Press button on the Teensy board
|
||||
3. Select a HEX file (File menu)
|
||||
4. Select "program" (Operations menu)
|
||||
5. Reboot (Operations menu).
|
||||
|
||||
Serial Console
|
||||
^^^^^^^^^^^^^^
|
||||
|
||||
A serial console is supported on an external MAX232/MAX3232 Connected
|
||||
on PD2 and PD3:
|
||||
|
||||
Port D, Bit 2: RXD1, Receive Data (Data input pin for the USART1). When
|
||||
the USART1 receiver is enabled this pin is configured as an input
|
||||
regardless of the value of DDD2. When the USART forces this pin to
|
||||
be an input, the pull-up can still be controlled by the PORTD2 bit.
|
||||
Port D, Bit 3: TXD1, Transmit Data (Data output pin for the USART1).
|
||||
When the USART1 Transmitter is enabled, this pin is configured as
|
||||
an output regardless of the value of DDD3.

Toolchains
|
||||
^^^^^^^^^^
|
||||
|
||||
There are several toolchain options. However, testing has been performed
|
||||
using *only* the NuttX buildroot toolchain described below. Therefore,
|
||||
the NuttX buildroot toolchain is the recommended choice.
|
||||
|
||||
The toolchain may be selected using the kconfig-mconf tool (via 'make menuconfig'),
|
||||
by editing the existing configuration file (defconfig), or by overriding
|
||||
the toolchain on the make commandline with CONFIG_AVR_TOOLCHAIN=<toolchain>.
|
||||
|
||||
The valid values for <toolchain> are BUILDROOT, CROSSPACK, LINUXGCC and WINAVR.
|
||||
|
||||
Buildroot:
|
||||
|
||||
There is a DIY buildroot version for the AVR boards here:
|
||||
http://bitbucket.org/nuttx/buildroot/downloads/. See the
|
||||
following section for details on building this toolchain.
|
||||
|
||||
Make sure that your PATH evirnoment variable includes the path the newly
|
||||
built binaries.
|
||||
|
||||
After configuring NuttX, make sure that CONFIG_AVR_BUILDROOT_TOOLCHAIN=y is set in your
|
||||
.config file.
|
||||
|
||||
WinAVR:
|
||||
|
||||
For Cygwin development environment on Windows machines, you can use
|
||||
WinAVR: http://sourceforge.net/projects/winavr/files/
|
||||
|
||||
Make sure that your PATH evirnoment variable includes the path the WinAvR
|
||||
binaries.
|
||||
|
||||
After configuring NuttX, make sure that CONFIG_AVR_WINAVR_TOOLCHAIN=y is set in your
|
||||
.config file.
|
||||
|
||||
WARNING: There is an incompatible version of cygwin.dll in the WinAVR/bin
|
||||
directory! Make sure that the path to the correct cygwin.dll file precedes
|
||||
the path to the WinAVR binaries!
|
||||
|
||||
Atmel Studio
|
||||
|
||||
Another option is to use the AVR toolchain provided within the Atmel Studio
|
||||
installation. Look in the Atmel/Studio directories and Program Files (x86)
|
||||
to find the tools in a subdirectory like toolchain/avr8/avr8-gnu-toolchain/bin.
|
||||
|
||||
Linux:
|
||||
|
||||
For Linux, there are widely available avr-gcc packages. On Ubuntu, use:
|
||||
sudo apt-get install gcc-avr gdb-avr avr-libc
|
||||
|
||||
After configuring NuttX, make sure that CONFIG_AVR_LINUXGCC_TOOLCHAIN=y is set in your
|
||||
.config file.
|
||||
|
||||
macOS:
|
||||
|
||||
For macOS, the CrossPack for AVR toolchain is available from:
|
||||
|
||||
http://www.obdev.at/products/crosspack/index.html
|
||||
|
||||
This toolchain is functionally equivalent to the Linux GCC toolchain.
|
||||
|
||||
Windows Native Toolchains
|
||||
^^^^^^^^^^^^^^^^^^^^^^^^^
|
||||
|
||||
The WinAVR toolchain is a Windows native toolchain. There are several
|
||||
limitations to using a Windows native toolchain 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.
|
||||
|
||||
An additional issue with the WinAVR toolchain, in particular, is that it
|
||||
contains an incompatible version of the Cygwin DLL in its bin/ directory.
|
||||
You must take care that the correct Cygwin DLL is used.
|
||||
|
||||
NuttX buildroot Toolchain
|
||||
^^^^^^^^^^^^^^^^^^^^^^^^^
|
||||
|
||||
If NuttX buildroot toolchain source tarball cne can be downloaded from the
|
||||
NuttX Bitbucket download site (https://bitbucket.org/nuttx/nuttx/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 Teensy++:<sub-dir>
|
||||
|
||||
NOTE: you also must copy avr-libc header files into the NuttX include
|
||||
directory with command perhaps like:
|
||||
|
||||
cp -a /cygdrive/c/WinAVR/include/avr include/.
|
||||
|
||||
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/avr-defconfig-4.5.2 .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
|
||||
detailed PLUS some special instructions that you will need to follow if you
|
||||
are building a toolchain for Cygwin under Windows.
|
||||
|
||||
avr-libc
|
||||
^^^^^^^^
|
||||
|
||||
Header Files
|
||||
|
||||
In any case, header files from avr-libc are required: http://www.nongnu.org/avr-libc/.
|
||||
A snapshot of avr-lib is included in the WinAVR installation. For Linux
|
||||
development platforms, avr-libc package is readily available (and would
|
||||
be installed in the apt-get command shown above). But if you are using
|
||||
the NuttX buildroot configuration on Cygwin, then you will have to build
|
||||
get avr-libc from binaries.
|
||||
|
||||
Header File Installation
|
||||
|
||||
The NuttX build will required that the AVR header files be available via
|
||||
the NuttX include directory. This can be accomplished by either copying
|
||||
the avr-libc header files into the NuttX include directory:
|
||||
|
||||
cp -a <avr-libc-path>/include/avr <nuttx-path>/include/.
|
||||
|
||||
Or simply using a symbolic link:
|
||||
|
||||
ln -s <avr-libc-path>/include/avr <nuttx-path>/include/.
|
||||
|
||||
Build Notes:
|
||||
|
||||
It may not necessary to have a built version of avr-lib; only header files
|
||||
are required. Bu if you choose to use the optimized libraru functions of
|
||||
the flowing point library, then you may have to build avr-lib from sources.
|
||||
Below are instructions for building avr-lib from fresh sources:
|
||||
|
||||
1. Download the avr-libc package from:
|
||||
|
||||
http://savannah.nongnu.org/projects/avr-libc/
|
||||
|
||||
I am using avr-lib-1.7.1.tar.bz2
|
||||
|
||||
2. Upack the tarball and cd into the
|
||||
|
||||
tar jxf avr-lib-1.7.1.tar.bz2
|
||||
cd avr-lib-1.7.1
|
||||
|
||||
3. Configure avr-lib. Assuming that WinAVR is installed at the following
|
||||
location:
|
||||
|
||||
export PATH=/cygdrive/c/WinAVR/bin:$PATH
|
||||
./configure --build=`./config.guess` --host=avr
|
||||
|
||||
This takes a *long* time.
|
||||
|
||||
4. Make avr-lib.
|
||||
|
||||
make
|
||||
|
||||
This also takes a long time because it generates variants for nearly
|
||||
all AVR chips.
|
||||
|
||||
5. Install avr-lib.
|
||||
|
||||
make install
|
||||
|
||||

||||
Common Configuration Notes
|
||||
--------------------------
|
||||
|
||||
1. Each Teensy++ configuration is maintained in a sub-directory and
|
||||
can be selected as follow:
|
||||
|
||||
tools/configure.sh teensy-2.0:<subdir>
|
||||
|
||||
Where <subdir> is one of the configuration sub-directories described in
|
||||
the following paragraph.
|
||||
|
||||
NOTE: You must also copy avr-libc header files, perhaps like:
|
||||
|
||||
cp -a /cygdrive/c/WinAVR/include/avr include/.
|
||||
|
||||
2. These configurations use the mconf-based configuration tool. To
|
||||
change a 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.
|
||||
|
||||
3. By default, all configurations assume the NuttX Buildroot toolchain
|
||||
under Cygwin with Windows. This is easily reconfigured:
|
||||
|
||||
CONFIG_HOST_WINDOWS=y
|
||||
CONFIG_WINDOWS_CYGWIN=y
|
||||
CONFIG_AVR_BUILDROOT_TOOLCHAIN=y
|
||||
|
||||
Configuration Sub-Directories
|
||||
-----------------------------
|
||||
|
||||
hello:
|
||||
The simple apps/examples/hello "Hello, World!" example.
|
||||
|
||||
nsh:
|
||||
This is a reduce NuttShell (NSH) configuration using apps/example/nsh.
|
||||
The serial console is provided on USART1 and can be accessed via
|
||||
an external RS-232 driver as described above under "Serial Console".
|
||||
|
||||
ostest:
|
||||
This configuration directory, performs a simple OS test using
|
||||
apps/examples/ostest. NOTE: The OS test is quite large. In order
|
||||
to get it to fit within AVR memory constraints, it will probably be
|
||||
necessary to disable some OS features.
|
||||
|
||||
usbmsc:
|
||||
This configuration directory exercises the USB mass storage
|
||||
class driver at apps/system/usbmsc. See apps/examples/README.txt
|
||||
for more information.
|
||||
|
||||
NOTE: THIS CONFIGURATION HAS NOT YET BEEN DEBUGGED AND DOES NOT
|
||||
WORK!!! ISSUES: (1) THE SPI DRIVER IS UNTESTED, (2) THE USB DRIVER
|
||||
IS UNTESTED, AND (3) THE RAM USAGE MIGHT BE EXCESSIVE.
|
||||
|
||||
Update 7/11: (1) The SPI/SD driver has been verified, however, (2) I
|
||||
believe that the current teensy-2.0/usbmsc configuration uses too
|
||||
much SRAM for the system to behave sanely. A lower memory footprint
|
||||
version of the mass storage driver will be required before this can
|
||||
be debugged.

* (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.

|

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

|

* 1. Provide logic in avr_spidev_initialize() to configure SPI
|

* chip select pins.
|

* 2. Provide avr_spiselect() and avr_spistatus() functions in your
|
||||
* board-specific logic. These functions will perform chip selection
|
||||
* and status operations in the way your board is configured.
|

* 3. Add a calls to at90usb_spidev_initialize() in your low level
|
||||
* application initialization logic
|
||||
* 4. The handle returned by avr_spibus_initialize() may then be used to
|
||||
* bind the SPI driver to higher level logic
|

* (e.g., calling mmcsd_spislotinitialize(),
