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.
Note, however, that both banks A and B of Flash contain
the PPCBug debugger.
The PPCBug hardware diagnostics are intended for testing and
troubleshooting the MVME230x 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
displays, and all of the debugger commands are
PPC1-Bug>
available. Diagnostics commands cannot be entered at the
prompt.
PPC1-Bug>
If you are in the diagnostic directory, the diagnostic prompt
displays, and all of the debugger and diagnostic
PPC1-Diag>
commands are available.
PPCBugÕs diagnostic test groups are listed in the Table 5-2. Note
that not all tests are performed on the MVME230x. 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.
