Introduction

The PPCBug firmware is the layer of software just above the hardware. The firmware provides
the proper initialization for the devices on the MVME5100 upon powerup or reset.
This chapter describes the basics of the PPCBug and its architecture. It also describes the
monitor (interactive command portion of the firmware), and provides information on using the
PPCBug debugger and the special commands. A complete list of PPCBug commands is also
provided.
For full user information about PPCBug, refer to the PPCBug Firmware Package User's Manual
and the PPCBug Diagnostics Manual, listed in

PPCBug Overview

The PPCBug debugger firmware is a powerful evaluation and debugging tool for systems built
around Motorola microprocessor. Facilities are available for loading and executing user
programs under complete operator control for system evaluation. The PPCBug provides a high
degree of functionality, user friendliness, portability and ease of maintenance.
The PPCBug also achieves its portability because it was written entirely in the C programming
language, except where necessary to use assembler functions.
PPCBug includes commands for:
PPCBug consists of three parts:
When using PPCBug, you operate out of either the debugger directory or the diagnostic
directory.
Display and modification of memory
Breakpoint and tracing capabilities
A powerful assembler and disassembler useful for patching programs
A self-test at powerup feature which verifies the integrity of the system
A command-driven, user-interactive software debugger, described in the PPCBug
Firmware Package User's Manual, listed in
(hereafter referred to as "debugger" or "PPCBug").
A command-driven diagnostics package for the MVME5100 hardware (hereafter
referred to as "diagnostics"). The diagnostics package is described in the PPCBug
Diagnostics Manual, listed in
A user interface or debug/diagnostics monitor that accepts commands from the
system console terminal.
