Overview - Motorola MVME2700 Series Installation And Use Manual

Overview

The PowerPC debugger, PPCBug, is a versatile tool used to evaluate and
debug systems built around Motorola PowerPC microcomputers. Its
primary uses are to test and initialize the system hardware, determine the
hardware configuration, and boot the operating system. Facilities are also
available for loading and executing user programs under complete
operator control for system evaluation.
The PowerPC debugger provides a high degree of functionality and user
friendliness, and yet stresses portability and ease of maintenance. It
achieves these features because it was written entirely in the C
programming language, except where necessary to use assembler
functions.
PPCBug includes commands for display and modification of memory,
breakpoint and tracing capabilities, a powerful assembler and disassembler
useful for patching programs, and a "self-test at power-up" feature which
verifies the integrity of the main CPU board. Various PPCBug routines
that handle I/O, data conversion, and string functions are available to user
programs through the System Call handler. PPCBug consists of three
parts:
When using PPCBug, you operate from within either the debugger
directory (PPC1-Bug) or the diagnostic directory (PPC1-Diag) which
tells you the current directory.
