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.
