board: arm: Add support for WeAct Mini STM31H7B0
This board is mostly the same as mini_stm32h743. Noatable diffrences for dt: - rcc config - octospi in quadspi mode - pinmux naming for USB and quadspi Signed-off-by: Sahaj Sarup <sahaj.sarup@linaro.org>

The default configuration per core can be found in the defconfig file:
|
||||
:zephyr_file:`boards/weact/mini_stm32h7b0/mini_stm32h7b0_defconfig`
|
||||
|
||||
Pin Mapping
|
||||
===========
|
||||
|
||||
MiniSTM32H7B0 Core board has 5 GPIO controllers. These controllers are responsible for pin muxing,
|
||||
input/output, pull-up, etc.
|
||||
|
||||
For more details please refer to `Mini_STM32H7B0 website`_.
|
||||
|
||||
Default Zephyr Peripheral Mapping:
|
||||
----------------------------------
|
||||
|
||||
The MiniSTM32H7B0 Core board is configured as follows
|
||||
|
||||
- USER_LED : PE3
|
||||
- USER_PB : PC13
|
||||
- SPI1 SCK/MISO/MOSI/NSS : PB3/PB4/PD7/PD6 (NOR Flash memory)
|
||||
- SPI4 SCK/MOSI/NSS : PE12/PE14/PE11 (LCD)
|
||||
- QuadSPI CLK/NCS/IO0/IO1/IO2/IO3 : PB2/PB6/PD11/PD12/PE2/PD13 (NOR Flash memory)
|
||||
- SDMMC1 CLK/DCMD/CD/D0/D1/D2/D3 : PC12/PD2/PD4/PC8/PC9/PC10/PC11 (microSD card)
|
||||
- USB DM/DP : PA11/PA12 (USB CDC ACM)
|
||||
|
||||
System Clock
|
||||
============
|
||||
|
||||
The STM32H7B0VB System Clock can be driven by an internal or external oscillator,
|
||||
as well as by the main PLL clock. By default, the System clock is driven
|
||||
by the PLL clock at 280MHz. PLL clock is fed by a 25MHz high speed external clock.
|
||||
|
||||
Serial Port (USB CDC ACM)
|
||||
=========================
|
||||
|
||||
The Zephyr console output is assigned to the USB CDC ACM virtual serial port.
|
||||
Virtual COM port interface. Default communication settings are 115200 8N1.
|
||||
|
||||
Programming and Debugging
|
||||
*************************
|
||||
|
||||
The MiniSTM32H7B0 Core board facilitates firmware flashing via the USB DFU
|
||||
bootloader. This method simplifies the process of updating images, although
|
||||
it doesn't provide debugging capabilities. However, the board provides header
|
||||
pins for the Serial Wire Debug (SWD) interface, which can be used to connect
|
||||
an external debugger, such as ST-Link.
|
||||
|
||||
Flashing
|
||||
========
|
||||
|
||||
To activate the bootloader, follow these steps:
|
||||
|
||||
1. Press and hold the BOOT0 key.
|
||||
2. While still holding the BOOT0 key, press and release the RESET key.
|
||||
3. Wait for 0.5 seconds, then release the BOOT0 key.
|
||||
|
||||
Upon successful execution of these steps, the device will transition into
|
||||
bootloader mode and present itself as a USB DFU Mode device. You can program
|
||||
the device using the west tool or the STM32CubeProgrammer.
|
||||
|
||||
Flashing an application to MiniSTM32H7B0
|
||||
----------------------------------------
|
||||
|
||||
Here is an example for the :zephyr:code-sample:`hello_world` application.
|
||||
|
||||
First, put the board in bootloader mode as described above. Then build and flash
|
||||
the application in the usual way. Just add ``CONFIG_BOOT_DELAY=5000`` to the
|
||||
configuration, so that USB CDC ACM is initialized before any text is printed,
|
||||
as below:
|
||||
|
||||
.. zephyr-app-commands::
|
||||
:zephyr-app: samples/hello_world
|
||||
:board: mini_stm32h7b0
|
||||
:goals: build flash
|
||||
:gen-args: -DCONFIG_BOOT_DELAY=5000
|
||||
|
||||
Run a serial host program to connect with your board:
|
||||
|
||||
.. code-block:: console
|
||||
|
||||
$ minicom -D <tty_device> -b 115200
|
||||
|
||||
Then, press the RESET button, you should see the following message after few seconds:
|
||||
|
||||
.. code-block:: console
|
||||
|
||||
Hello World! mini_stm32h7b0
|
||||
|
||||
Replace :code:`<tty_device>` with the port where the board XIAO BLE
|
||||
can be found. For example, under Linux, :code:`/dev/ttyACM0`.
|
||||
|
||||
Debugging
|
||||
---------
|
||||
|
||||
This current Zephyr port does not support debugging.
|
||||
|
||||
Testing the LEDs in the MiniSTM32H7B0
|
||||
*************************************
|
||||
|
||||
There is a sample that allows to test that LED on the board are working
|
||||
properly with Zephyr:
|
||||
|
||||
.. zephyr-app-commands::
|
||||
:zephyr-app: samples/basic/blinky
|
||||
:board: mini_stm32h7b0
|
||||
:goals: build flash
|
||||
:gen-args: -DCONFIG_BOOT_DELAY=5000
|
||||
|
||||
You can build and flash the examples to make sure Zephyr is running correctly on
|
||||
your board. The LED definitions can be found in
|
||||
:zephyr_file:`boards/weact/mini_stm32h7b0/mini_stm32h7b0.dts`.
|
||||
|
||||
Testing shell over USB in the MiniSTM32H7B0
|
||||
*******************************************
|
||||
|
||||
There is a sample that allows to test shell interface over USB CDC ACM interface
|
||||
with Zephyr:
|
||||
|
||||
.. zephyr-app-commands::
|
||||
:zephyr-app: samples/subsys/shell/shell_module
|
||||
:board: mini_stm32h7b0
|
||||
:goals: build flash
|
