Connections and IOs

STM32H5F5J-DK Discovery Board has 9 GPIO controllers. These controllers are responsible for pin muxing, input/output, pull-up, etc.

For more details please refer to STM32H5F5J-DK Discovery board User Manual.

Default Zephyr Peripheral Mapping:

  • USART_2 TX/RX : PA2/PA3 (VCP)

  • UART_7 TX/RX : PE8/PE7 (ARDUINO® UART7)

  • USER_PB : PI8

  • LD1 (red) : PH10

  • LD2 (green) : PA5

  • LD3 (blue) : PB9

  • LD4 (orange) : PD15

  • ADC1 channel 0 input : PA0

System Clock

STM32H5F5J-DK System Clock could be driven by internal or external oscillator, as well as main PLL clock. By default System clock is driven by PLL clock at 250MHz, driven by 48MHz external oscillator (HSE).

Serial Port

STM32H5F5J-DK Discovery board has 3 U(S)ARTs. The Zephyr console output is assigned to USART2. Default settings are 115200 8N1.

TFT LCD screen and touch panel

The TFT LCD screen and touch panel are supported for the STM32H5F5J-DK Discovery board. They can be tested using LVGL basic sample sample:

# From the root of the zephyr repository
west build -b stm32h5f5j_dk samples/subsys/display/lvgl

Programming and Debugging

The stm32h5f5j_dk board supports the runners and associated west commands listed below.

flash debug attach debugserver
stlink_gdbserver ✅ (default)
stm32cubeprogrammer ✅ (default)

STM32H5F5J-DK Discovery board includes an ST-LINK/V3E embedded debug tool interface.

Applications for the stm32h5f5j_dk board configuration can be built and flashed in the usual way (see Building an Application and Run an Application for more details).

OpenOCD Support

For now, OpenOCD support for STM32H5 is not available on upstream OpenOCD. You can check OpenOCD official Github mirror. In order to use it though, you should clone from the customized STMicroelectronics OpenOCD Github and compile it following usual README guidelines. Once it is done, you can set the OPENOCD and OPENOCD_DEFAULT_PATH variables in boards/st/stm32h5f5j_dk/board.cmake to point the build to the paths of the OpenOCD binary and its scripts, before including the common openocd.board.cmake file:

set(OPENOCD "<path_to_openocd_repo>/src/openocd" CACHE FILEPATH "" FORCE)
set(OPENOCD_DEFAULT_PATH <path_to_opneocd_repo>/tcl)
include(${ZEPHYR_BASE}/boards/common/openocd.board.cmake)

Flashing

The board is configured to be flashed using west STM32CubeProgrammer runner, so its installation is required.

Application in SoC Flash

Connect the STM32H5F5J-DK Discovery to your host computer using the USB port. Then build and flash an application. Here is an example for the Hello World application.

Run a serial host program to connect with your Nucleo board:

$ minicom -D /dev/ttyACM0

Then build and flash the application.

# From the root of the zephyr repository
west build -b stm32h5f5j_dk samples/hello_world
west flash

You should see the following message on the console:

Hello World! stm32h5f5j_dk/stm32h5f5xx

Debugging

You can debug an application in the usual way. Here is an example for the Hello World application.

# From the root of the zephyr repository
west build -b stm32h5f5j_dk samples/hello_world
west debug
