User’s Manual 152.3.1 Running Dynamic C via Serial Programming CableDynamic C uses the serial port on your PC that you specified during installation.If you are using a USB port to connect your computer to the RCM3365/RCM3375 module,choose Options > Project Options and select “Use USB to Serial Converter” on theCommunications tab.2.3.1.1 Run a Sample ProgramUse the File menu to open the sample program PONG.C, which is in the Dynamic CSAMPLES folder. Press function key F9 to compile and run the program. The STDIOwindow will open on your PC and will display a small square bouncing around in a box.This program shows that the CPU is working. The sample program described inSection 6.5, “Run the PINGME.C Sample Program,” tests the TCP/IP portion of the board.2.3.1.2 TroubleshootingIf Dynamic C cannot find the target system (error message "No Rabbit ProcessorDetected."):• Check that the RCM3365/RCM3375 is powered correctly — the red CORE LED on thePrototyping Board should be lit when the RCM3365/RCM3375 is mounted on the PrototypingBoard and the AC adapter is plugged in.• Check both ends of the programming cable to ensure that they are firmly plugged intothe PC and the PROG connector, not the DIAG connector, is plugged in to the program-ming port on the RCM3365/RCM3375 with the marked (colored) edge of the program-ming cable towards pin 1 of the programming header.• Ensure that the RCM3365/RCM3375 module is firmly and correctly installed in itsconnectors on the Prototyping Board.• Dynamic C uses the COM port specified during installation. Select a different COMport within Dynamic C. From the Options menu, select Project Options, then selectCommunications. Select another COM port from the list, then click OK. Press

to force Dynamic C to recompile the BIOS. If Dynamic C still reports it isunable to locate the target system, repeat the above steps until you locate the COM portused by the programming cable.If Dynamic C appears to compile the BIOS successfully, but you then receive a communi-cation error message when you compile and load the sample program, it is possible thatyour PC cannot handle the higher program-loading baud rate. Try changing the maximumdownload rate to a slower baud rate as follows.• Locate the Serial Options dialog in the Dynamic C Options > Project Options >Communications menu. Select a slower Max download baud rate.If a program compiles and loads, but then loses target communication before you canbegin debugging, it is possible that your PC cannot handle the default debugging baudrate. Try lowering the debugging baud rate as follows.• Locate the Serial Options dialog in the Dynamic C Options > Project Options >Communications menu. Choose a lower debug baud rate.
