3.5.1 Diagnostics
The PPCBug hardware diagnostics are intended for testing and troubleshooting the
MVME5100.
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 PPC6-Bug> is displayed, and all of
the debugger commands are available. Diagnostics commands cannot be entered at the PPC6-
Bug> prompt.
If you are in the diagnostic directory, the diagnostic prompt PPC6-Diag> is displayed, and all of
the debugger and diagnostic commands are available.
PPCBug’s diagnostic test groups are listed in Table 3-2 . Note that not all tests are performed on
the MVME5100. Using the HE command, you can list the diagnostic routines available in each
test group. Refer to the PPCBug Diagnostics Manual, listed in
Appendix D, Related
Documentation for complete descriptions of the diagnostic routines and instructions on how to
invoke them.

Command Description
Although a command (PFLASH) 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, if the target
address addresses the bank in which it resides.
