[STM32H750] Working board definitions and some questions

[SunWukong]

Hello jahr, thanks for the quick reply and sorry, that was my mistake.

I had already read all the information that WeAct offers, including the information you linked, but had overlooked the fact that WeAct offers an ExternalLoader for downloading and had therefore worked with a different downloader. I noticed this on my own this morning, but I still overlooked the fact that I can't flash the QSPI Flash via DFU.

After reading your answer, I read through each step again and then I realised that I had to use an STLINK. Then, of course, flashing firmware1.bin worked straight away and I was able to access the board immediately via Repl.

The build has worked well so far with these board definitions.

Code: Select all

LINK build-WEACT_H750/firmware.elf
   text    data     bss     dec     hex filename
 384144      24   32352  416520   65b08 build-WEACT_H750/firmware.elf
INFO: this build places firmware in external QSPI flash
GEN build-WEACT_H750/firmware0.bin
GEN build-WEACT_H750/firmware1.bin
GEN build-WEACT_H750/firmware.dfu

Unfortunately, I could not successfully flash the firmware afterwards.

Code: Select all

make BOARD=WEACT_H750 deploy
Writing build-WEACT_H750/firmware.dfu to the board
Traceback (most recent call last):
  File "/home/mike/micropython/ports/stm32/../../tools/pydfu.py", line 22, in <module>
    import usb.core
ModuleNotFoundError: No module named 'usb'
make: *** [Makefile:665: deploy] Fehler 1

I then transferred the firmware0.bin and firmware1.bin files to a PC with Windows on which the STM32CubeProgrammer is installed. firmware0.bin could be flashed without any problems. With firmware1.bin I found out that the STM32CubeProgrammer cannot handle the installed external QSPI Flash (W25Q64 ) by default. I then found what I was looking for in the ST Community Forum.
STM32CubeIDE STM32H750VB QSPI External loader Problem
After I had copied this helper programm into a directory that seemed suitable to me, I was able to select the W25Q64 chip and theoretically flash it, but in the end there were unfortunately error messages.

Now I am at a loss, but tomorrow, no today, I will search the net and maybe I will find out what I am doing wrong.

I follow up this program and getting issues or errors in aero WA.

If you expect any help you have to be specific about the errors and issues you get.

Hello SunWukong, try to flash firmware1.bin using the instructions on the page GBWhatsApp APKhttps://github.com/WeActTC/MiniSTM32H7x ... PI_Flasher. It worked well for me

i'm really grateful for this link. I was struggling flashing the firmware, but these instructions helped me. great work sharing it.
