**RESOLVED** unbricking the mpu11

Post by bonestock »

With the miraculous help of tab completion and a healthy bit of carelessness via the console, mpucomp.exe overwrote mpu11.hex and not mpu.plc. CNC11 then loaded this bad firmware upon restart and now my mpu11 is not booting. :oops:

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.

Thank you. The boot stick did the trick.
