3.4 Starting Dynamic C
Once the RCM2000 module 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 speci-
fied during installation (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 in the next chapter.
3.4.1 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. If it is, check both ends of the programming cable to ensure that it is firmly plugged
into the PC and the RCM2000’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
Project Options
, then 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 > Project Options >
Communications
menu. Change the baud rate to 57,600 bps.
