i added 2 shield wires to MS ground, went to start the car up and it wouldnt start and now i cannot communicate with the unit.
Ive tried the serial loopback test and can communicate up to the microprocessor (when shorting pins 12-13 i can communicate with MS in hyperterminal).
I have then gone to reload the firmware and recieved a message:
download failed: expected responseboot>",
but received this "".
there is 5V to all the correct pins on the micro.
any suggestions? thanks.
