Please note: the way to get technical support is to summarize circumstances and your exact findings on THEMATICALLY editable page (not email; email is not guaranteed to arrive, not editable after sending so might contain outdated information (worse: there might be other newer versions that just waste time by having to be merged manually or might have not arrived and waste even more time or cause great confusion - a completely wrong way no matter how widely it is used), a waste of time, and not supported. Sending to arbitrary email address is especially not supported and might me neglected.

can be tried especially if no "Boot mode detected" message.
  • if "Boot mode detected", then already in boot mode so RS232 serial port loopback will not help.
