Re: Failed to init device yet again
Here is another long shot at this ....
Compile the blink sketch, then note where the blink.ino.bin file is from the output of the IDE.
Copy that file somewhere.
Download the STM32 Windows Flasher from here https://www.st.com/en/development-tools/flasher-stm32.html
Place the jumper in the FLASH position.
Then using the Windows Flasher, try to flash the above blink.ino.bin, and see if
a) flashing is successful
b) the LED on the STM32 flashes (or not).
I am trying to side step the IDE as the flashing method.
