2.3.1 Troubleshooting

If you receive the message No Rabbit Processor Detected, the programming
cable may be connected to the wrong COM port, a connection may be faulty, or the target
system may not be powered up. First, check to see that the power LED on the Prototyping
Board is lit and that the jumper across pins 5–6 of header JP10 on the Prototyping Board is
installed. If the LED is lit, check both ends of the programming cable to ensure that it is
firmly plugged into the PC and the programming port on the Prototyping Board. Ensure
that the module is firmly and correctly installed in its connectors on the Prototyping
Board.
