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, Related Documentation.

5.8Diagnostic 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.
