3.3 Starting Dynamic C
Once the RCM3100 is set up and connected as described in Chapter 2 and Dynamic C has
been installed, start Dynamic C by double-clicking on the Dynamic C icon. Dynamic C
should start, then look for the target system on the COM port you specified during installa-
tion (by default, COM1). Once detected, Dynamic C should go through a sequence of
steps to cold-boot the module and compile the BIOS.
If you receive the message beginning
"BIOS successfully compiled"
you are
ready to continue with the sample programs.
3.3.1 Communication Error Messages
If you receive the message
"No Rabbit Processor Detected,"
the programming
cable may be connected to a different 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 JP1 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 RCM3100 series module’s programming port. If you
are using the Prototyping Board, ensure that the module is firmly and correctly installed in
its connectors.
If there are no faults with the hardware, select a different COM port within Dynamic C.
From the Options menu, select Communications. The dialog shown should appear.
Select another COM port from the list, then click OK. Press <Ctrl-Y> to force Dynamic C to recom-
pile the BIOS. If Dynamic C still reports it is unable to locate the target system, repeat the above
steps until you locate the active COM port.
If Dynamic C appears to compile the BIOS successfully, but you then receive a communi-
cation error message, it is possible that your PC cannot handle the 115,200 bps baud rate.
Try changing the baud rate to 57,600 bps as follows.
•
Locate the Serial Options dialog in the Dynamic C Options > Communications
menu. Change the baud rate to 57,600 bps.
