stm32 board runner can flash external NOR with STM32CubeProgrammer by FRASTM · Pull Request #68377 · zephyrproject-rtos/zephyr

FRASTM · 2024-01-31T16:59:25Z

Add an option to the STM32CubeProgrammer board runner to include the external loader corresponding to the target board.
The west flash command is updated to support the option and flash external octo-NOR with an external loader.
This is mainly use for stm32 disco kit target boards where the external NOR flash is in MemoryMapped mode, for XiP.
The external flash memory is mapped to 0x70000000. for stm32u585 disco kit
The external flash memory is mapped to 0x90000000. for stm32h7b3 disco kit

The board runner STM32CubeProgrammer is updated to get :

the hexa file to flash board_runner_args(stm32cubeprogrammer "--hex-file=${ZEPHYR_BASE}/build/zephyr/zephyr.hex")
the address of the external flash to write board_runner_args(stm32cubeprogrammer "--tool-opt=0x70000000")
the external loader to use for flashing it board_runner_args(stm32cubeprogrammer "--extload=MX25LM51245G_STM32U585I-IOT02A.stldr")

Dear @FRASTM,

I ran the west build -p always -b stm32h7b3i_dk samples/application_development/code_relocation_nocopy/ command and west flash. However, I got a fault.

Do I need to do anything else? Thank you!

The reason is that you probably miss the corresponding update of the boards/arm/stm32h7b3i_dk/board.cmake
Additionally, the external NOR flash where the piece of code is being executed must be configured in XiP mode.
That's what I did here https://github.com/FRASTM/zephyr/tree/xip_ospi

Maybe it is worth mentioning that external loader must be located within STM32CubeProgrammer/bin/ExternalLoader directory. The STM32_Programmer_CLI 's -el expects absolute path but the runner doesn't. That creates confusion and requires to dig into the runner's code.

In order to west flash the stm32 target, with the STM32CubeProgrammer runner, the external flash loader has to be specified in the board.cmake as follows (for stm32h7b3i_dk as an example):
