UPDATE: The connect issue was solved using suggestion in following thread:

STM32 + VS Code + mbed upload issue: Error: libusb_open() failed with LIBUSB_ERROR_ACCESS Error: open failed - #12 by maxgerhardt?

Following reset config solved the connect for me:

reset_config srst_only srst_nogate connect_assert_srst

Open is that after programming the MCU the reset is not completed. Most likey an openOCD related config issue. Will update this issue once I found the solution.

Update: Found out that the upload does work BUT the reset in the openOCD does not work.

_C:\Users\jeroen.platformio\packages\tool-openocd\bin\openocd -d2 -s C:\Users\jeroen.platformio\packages\tool-openocd/scripts -f board/JENG_STM32L082KZ.cfg -c "program {.pio\build\STM32L082bank1\firmware.elf} verify; reset; shutdown;"

When removing the reset in the above command there are no errors. Of course in this case I have to reset the MCU manually. So I am still looking for a way to solve this. However afaik this is not related to platformio.

Therefore I will close this issue in the coming weeks (in case I find a solution beforehand I will share the info here)

Does this also work for MAX7800x?
