2.3 Starting Dynamic C
Once the RCM3600 is connected as described in the preceding pages, start Dynamic C by
double-clicking on the Dynamic C icon or by double-clicking on
dcrabXXXX.exe
in
the Dynamic C root directory, where
XXXX
are version-specific characters. Dynamic C
uses the serial COM port on your PC that you specified during installation.
If you are using a USB port to connect your computer to the RCM3600 module, choose
Options > Project Options
and select “Use USB to Serial Converter.”
2.4 Run a Sample Program
Use the
File
menu to open the sample program
PONG.C
, which is in the Dynamic C
SAMPLES
folder. Press function key F9 to compile and run the program. The STDIO win-
dow will open on your PC and will display a small square bouncing around in a box.
2.4.1 Troubleshooting
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 there are any other problems:
•
Check that the RCM3600 is powered correctly — the power LED above the
RESET
button on the Prototyping Board should be lit.
•
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 RCM3600.
•
Ensure that the RCM3600 module is firmly and correctly installed in its connectors 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.
