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. 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 header on the RCM4200 with the marked
(colored) edge of the programming cable towards pin 1 of the programming header. Ensure
that the module is firmly and correctly installed in its connectors on the Prototyping Board.
If Dynamic C appears to compile the BIOS successfully, but you then receive a communi-
cation error message when you compile and load a sample program, it is possible that your
PC cannot handle the higher program-loading baud rate. Try changing the maximum
download rate to a slower baud rate as follows.

If a program compiles and loads, but then loses target communication before you can

rate. Try lowering the debugging baud rate as follows.
