Restoring mpu11.hex from an earlier backup and restarting CNC11 does not seem to be much use. Only the 5V LED is on.
Since the board is not available via ethernet, I assume I will need to rescue things by interfaceing with the board over a serial connection. Can someone please provide instruction and the pin-out I may need.
