General Information

contains a battery of utilities and tests for exercise, test, and debug

of hardware in the PowerPC board environment. The diagnostics

are menu-driven for ease of use.

❏ A user interface or debug/diagnostics monitor that accepts

commands from the system console terminal. The tests described in

this manual are implemented by the firmware, commands are input,

and results are reported via this monitor, which is the common

device used for both the debugger and the diagnostics. The monitor

is command-line driven and provides input and output facilities,

command parsing, error reporting, interrupt handling, and a multi-

level directory for menu selection.

Debugger and Diagnostic Directories

When using PPCBug, operate from either the debugger directory or the

diagnostic directory:

❏ When in the debugger directory, the debugger prompt PPCx-Bug> is

displayed and all of the debugger commands are available.

Note Earlier versions of this firmware, e.g., PPC1Bug, will not

contain all commands available in later versions, such as

PPC6Bug.

❏ When in the diagnostic directory, the diagnostic prompt PPCx-

Diag>

is displayed and all of the diagnostic commands are

available, as well as all of the debugger commands.

To use the diagnostic part of the firmware, the diagnostic directory must

be open. If the

PPC

-Bug> prompt (debugger directory) is displayed, the

wrong directory is open. To switch to the diagnostic directory enter SD

(Switch Directories command). This displays the diagnostic prompt

PPC

-Diag>.

To examine the commands in the current open directory use the Help (HE)

command.
