167Bug Firmware
Introduction
The 167Bug firmware is the layer of software just above the hardware. The
firmware supplies the appropriate initialization for devices on the
MVME167P board upon power-up or reset.
This chapter describes the basics of 167Bug and its architecture, describes
the monitor (interactive command portion of the firmware) in detail, and
gives information on using the debugger and special commands. A list of
167Bug commands appears at the end of the chapter.
For complete user information about 167Bug, refer to the Debugging
Package for Motorola 68K CISC CPUs User’s Manual and to the
MVME167Bug Diagnostics User’s Manual, listed in
.
167Bug Overview
The firmware for the M68000-based (68K) series of board and system
level products has a common genealogy, deriving from the Bug firmware
currently used on all Motorola M68000-based CPUs. The M68000
firmware version implemented on the MVME167P MC68040-based
single-boare computer is known as MVME167Bug, or 167Bug. It includes
diagnostics for testing and configuring IndustryPack modules.
167Bug is a powerful evaluation and debugging tool for systems built
around MVME167P CISC-based microcomputers. Facilities are available
for loading and executing user programs under complete operator control
for system evaluation. The 167Bug firmware provides a high degree of
functionality, user friendliness, portability, and ease of maintenance.
