Solving Startup Problems
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.
