Issue: Board is not responding
Details: Hey, I tried to send any command but I get no response:
After that I tried to format the board with the RAK upgrade but it failed. So I tried to download firmware to the board but I keep getting this error:
I checked even with STM32programmer but still:
The last thing that I tired is to reset the bootloader with the reset button but I get nothing back:
You can see that there is a red led turned on and that I connected the boot jumper.
The computer recognize the board:
What else can I do to fix that?
