2.3.1 Troubleshooting
If you receive the message Could Not Open Serial Port, check that the COM port
assigned to the USB programming cable was identified and set up in Dynamic C as
described in the preceding section.
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 RCM5400W 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.
Locate the Serial Options dialog on the “Communications” tab in the Dynamic C
Options > Project Options
menu. Select a slower Max download baud rate. Click OK
to save.
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.
Locate the Serial Options dialog on the “Communications” tab in the Dynamic C
Options > Project Options
menu. Choose a lower debug baud rate. Click OK to save.
Press <Ctrl-Y> to force Dynamic C to recompile the BIOS. You should receive a Bios
compiled successfully
message once this step is completed successfully.
