2.3 Run a Sample Program
Once the RCM4300 is connected as described in the preceding pages, start Dynamic C by
double-clicking on the Dynamic C icon on your desktop or in your

This program shows that the CPU is working. The sample program described in
Section 6.5, “Run the PINGME.C Sample Program,” tests the TCP/IP portion of the board.
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 RCM4300 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
begin debugging, it is possible that your PC cannot handle the default debugging baud
rate. Try lowering the debugging baud rate as follows.
