Diagnostic Tests
The PPCBug hardware diagnostics are intended for testing and troubleshooting the CPCI-6020
module.
In order to use the diagnostics, you must change to the diagnostic directory. You may change
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
PPC-Bug>
displays, and all of the
debugger commands are available. Diagnostics commands cannot be entered at the
PPC-
Bug>
prompt.
If you are in the diagnostic directory, the diagnostic prompt
PPC-Diag>
displays, and all of the
debugger and diagnostic commands are available.
Note that not all tests are valid for the CPCI-6020. 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.
You may enter command names in either uppercase or lowercase.
Some diagnostics depend on restart defaults that are set up only in a particular restart mode.
Refer to the documentation on a particular diagnostic for the correct mode.
Some test groups have subtests. For example, enter the command
PPC-Bug>he
ram
to
access the RAM test group subtests. This will display the subtests, which you can run
separately as RAM tests.

Data Loss
Although a command that allows erasing and reprogramming of flash memory is
available, note that reprogramming any portion of the CPCI-6020 baseboard’s flash
memory (Bank B) will erase everything currently contained in the baseboard flash,
including the PPCBug debugger.
Use caution when reprogramming or erasing flash memory. Refer to the programming
documents listed in
Appendix A,
