Trying to flash:

Using ‘COM5’ as serial port.
Unexpected error: could not open port ‘COM5’: PermissionError(13, ‘Ingen tilgang.’, None, 5)

Not sure how to proceed, I am not a programmer and the PY/api/putty/ is daunting to me.

side note: I use termite rs232 serial terminal for most simple serial related Q&A…
can you directly control the unit by sending serial text to it, if so where do I find a list of commands?

If it helps, this is what I got from the termite:
