port custom stm32h750 external flash loader stldr to a openocd config file

[JCuna.1]

Hi, I recently create a external flash loader for a custom board with stm32h750. I can use correctly the stldr file in stm32cubeprogrammer. However, I am planning to use openocd on a raspberry pi with stlinks in order to flash mcu in my boards and also the external flash.

I have checking openocd stm32 branch in github and there is a file located in https://github.com/STMicroelectronics/OpenOCD/blob/openocd-cubeide-r4/tcl/board/stm32h7x_dual_qspi.cfg which contains the external flash loader configuration for stm32h7, but this is a custom code for openocd.

So I am not sure if I need to port my stldr file to this config openocd, or there is another simple way.

Any suggestion to do that?

For the H7 the IO Compensation Cell ?

Actually I've tested several H7-boards at 3.3V and 1.8V with QSPI/OctoSPI. Never touched the compensation cell settings and no problems. Well, always used a conservative clock setting, close to the limits things might be different.
