Introduction
This manual describes the complete set of hardware diagnostics included
in the PPCBug Debugging Package, intended for testing and
troubleshooting Motorola’s PowerPC-based boards. This member of the
PPCBug firmware family, known as PPCBug diagnostics, is implemented
on many of the Motorola PowerPC-based products as part of a standard
proprietary debugging and diagnostic tool set.
Boards using this tool set are referred to in this manual as the PowerPC
board or board. When necessary to refer to them individually, they are
referred to by their individual product names, such as MVME210x,
MVME230x, MVME360x, MVME510x, MCP750, MTX, etc.
This introductory chapter includes information about the operation and use
of the diagnostics. Chapter 2 contains descriptions of the diagnostic
utilities. Chapter 3 contains descriptions of the diagnostic test routines.
Before using the PPCBug diagnostics, ensure that the PowerPC board and
other hardware are properly configured and connected, according to the
installation guide for that particular PowerPC board. The two-volume
manual for the PPCBug Debugging Package, PPCBug Firmware Package
User’s Manual, should also be available. It contains a complete description
of PPCBug, the start-up procedure, all general software debugging
commands, and other information about the debugger.
