Caution

Although a command to allow the erasing and reprogramming of flash memory is available to you, keep in mind that reprogramming any portion of flash memory will erase everything currently contained in flash, including the PPCBug debugger.

Diagnostic Tests

The PPCBug hardware diagnostics are intended for testing and troubleshooting the PrPMC800/800ET module.

In order to use the diagnostics, you must switch to the diagnostic directory. You may switch between directories by using the SD (Switch Directories) command. You may view a list of the commands in the directory that you are currently in by using the HE (Help) command.

If you are in the debugger directory, the debugger prompt PPC7-Bug>displays, and all of the debugger commands are available. Diagnostics commands cannot be entered at the PPC7- Bug> prompt.

If you are in the diagnostic directory, the diagnostic prompt PPC7-Diag>displays, and all of the debugger and diagnostic commands are available.

PPCBug’s diagnostic test groups are listed in the following table. Note that not all tests are performed on the PrPMC800/800ET. Using the HE command, you can list the diagnostic routines available in each test group. Refer to the PPCBug Diagnostics Manual for complete descriptions of the diagnostic routines and instructions on how to invoke them.
