Pin Mapping
Default Zephyr Peripheral Mapping:
The weact_stm32h5_core board is configured as follows
USER_LED : PB2
USER_PB : PC13
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)
UART on debug header : RX/TX - pA10/PA9
System Clock
The STM32H562RG 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 240MHz. PLL clock is fed by a 8MHz 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 weact_stm32h5_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:
Press and hold the BOOT0 key.
While still holding the BOOT0 key, press and release the RESET key.
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 weact_stm32h5_core
Here is an example for the 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:
# From the root of the zephyr repository
west build -b weact_stm32h5_core samples/hello_world -- -DCONFIG_BOOT_DELAY=5000
west flash
Run a serial host program to connect with your board:
$ minicom -D <tty_device> -b 115200
Then, press the RESET button, you should see the following message after few seconds:
Hello World! weact_stm32h5_core
Replace <tty_device> with the port where the board can be found.
For example, under Linux, /dev/ttyACM0.
Debugging
This current Zephyr port does not support debugging.
Testing the LEDs in the weact_stm32h5_core
There is a sample that allows to test that LED on the board are working properly with Zephyr:
# From the root of the zephyr repository
west build -b weact_stm32h5_core samples/basic/blinky -- -DCONFIG_BOOT_DELAY=5000
west flash
You can build and flash the examples to make sure Zephyr is running correctly on your board. The LED definitions can be found in boards/weact/stm32h5_core/weact_stm32h5_core.dts.
Testing shell over USB in the weact_stm32h5_core
There is a sample that allows to test shell interface over USB CDC ACM interface with Zephyr:
# From the root of the zephyr repository
west build -b weact_stm32h5_core samples/subsys/shell/shell_module -- -DCONFIG_BOOT_DELAY=5000
west flash
