In the event of difficulty with your CPU board, try the simple
troubleshooting steps on the following pages before calling for help or
sending the board back for repair. Some of the procedures will return the
board to the factory debugger environment (the board was tested under
those conditions before it left the factory). The self-tests may not run in all
user-customized environments.
