Troubleshooting
Reasons Why the Debugger Won’t Open
•
If a series of error notifications appear, the debugger may have launched when the board is not
powered. Cancel these messages, close the debugger window, and power up the board before
opening the debugger again.
•
You may not have installed the special edition license key for this version (3.1) of CodeWarrior (see
the CodeWarrior Quick Start Guide included with the CodeWarrior CD provided).
•
If the debugger could not establish a connection, press the RESET button on the DEMO board,
and retry.
•
The COM port on the PC may be in use by another application. If so, disconnect that application
or connection.
•
SW3 switch may not be in the correct position (position 0 to Flash memory and position 1 to run
program). Please check your steps.
Reasons Why the Ping Test Might Fail
•
Ethernet cable may not be secure.
•
IP addresses or masks may not be set correctly. The mask is typically 255.255.255.0. To check
the board’s and the PC’s IP addresses, you must install and open CodeWarrior and do the steps
in “
Set the PC’s IP address and the Ping Test
.”
•
You may not have waited long enough for the PC to regain its IP settings. This shouldn’t take more
than a minute and takes typically 1-20 seconds.
