2.4.1 Troubleshooting
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 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 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 in the Dynamic C Options > Project Options >
Communications menu. Choose a lower debug baud rate.
If Dynamic C cannot find the target system (error message
"No Rabbit Processor
Detected."
)
:
•
Check that the RabbitCore or PowerCore module is powered correctly — the power
LEDs on the Prototyping Board should be lit when the module is mounted on the Proto-
typing Board and the wall transformer is plugged in.
•
Check to make sure you are using the PROG connector, not the DIAG connector, on the
programming cable.
•
Check both ends of the programming cable to ensure that they are firmly plugged into
the PC and the programming port on the RabbitCore or PowerCore module.
•
Ensure that the RabbitCore or PowerCore module is firmly and correctly installed in its
socket on the Interposer Board.
•
Ensure that the Interposer Board is firmly and correctly installed in its socket on the
Prototyping Board.
•
Select a different COM port within Dynamic C. From the Options menu, select
Project Options , then select Communications . Select another COM port from the list,
then click OK. Press <Ctrl-Y> to force Dynamic C to recompile 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.
