STM32H723VGT6 board files for WeAct

[davefes]

I tried downloading NUCLEO_H723ZG-20241025-v1.24.0.hex to the board and using D8 and D9 for REPL ... I was not surprised that REPL didn't work. Possibly something to do with setting up the oscillators correctly.

WeAct have an OpenMV project:
https://github.com/WeActStudio/MiniSTM32H7xx/tree/master/SDK/openmv
but before I launch into that endeavour I wondered if anyone has got standard Micropython working on this board and would be willing to share their board files.

I would be happy with internal flash as it is the GPIO I need rather than program space.

Thank you.

P.S. just found this https://github.com/nspsck/MiniSTM32H723_Micropython_Port. I will update this post with progress

Wow, a REPL! @nspsck thanks for posting that project.

@nspsck, now I would like 75 GPIO. I will go through mpconfigboard.h and disable the peripherals that I do not need. I will probably want to disable OSPI flash. Could you tell me the make command to build without OSPI?

Thank you.

If I remember correctly, you have to delete these lines, and maybe also delete bdev.c, that file should not be read if you take these lines out, but I am not entirely sure about that.

Thanks very much for that.

Thought I would try building using the files on GitHub and make -j LTO=1 BOARD=WEACT_H723.

I see HSE_VALUE (25000000) in `stm32H7xx_hal_conf.h, but that is the limit of my debugging capabilities.
