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 CodeSourcery 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:

* implementation without modification. The argument has no

|

* or whatever you would like to do with it. Every implementation

*
|

* 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).

* Description:
|

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

* peripherals. In that case, the pins are completely controlled by the

|

*
|
||||
* 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
