GEPPCBug Firmware Package User’s Manual Parts 1 & 2

Ground the Instrument.

To minimize shock hazard, the equipment chassis and enclosure must be connected to an electrical ground.

The equipment is supplied with a three-conductor ac power cable. The power cable must be plugged into

an approved three-contact electrical outlet. The power jack and mating plug of the power cable meet

International Electrotechnical Commission (IEC) safety standards.

Do Not Operate in an Explosive Atmosphere.

Do not operate the equipment in the presence of flammable gases or fumes. Operation of any electrical

equipment in such an environment constitutes a definite safety hazard.

Keep Away From Live Circuits.

Operating personnel must not remove equipment covers. Only Factory Authorized Service Personnel or

other qualified maintenance personnel may remove equipment covers for internal subassembly or

component replacement or any internal adjustment. Do not replace components with power cable

connected. Under certain conditions, dangerous voltages may exist even with the power cable removed. To

avoid injuries, always disconnect power and discharge circuits before touching them.

Do Not Service or Adjust Alone.

Do not attempt internal service or adjustment unless another person capable of rendering first aid and

resuscitation is present.

Use Caution When Exposing or Handling the CRT.

Breakage of the Cathode-Ray Tube (CRT) causes a high-velocity scattering of glass fragments (implosion).

To prevent CRT implosion, avoid rough handling or jarring of the equipment. Handling of the CRT should

be done only by qualified maintenance personnel using approved safety mask and gloves.

Do Not Substitute Parts or Modify Equipment.

Because of the danger of introducing additional hazards, do not install substitute parts or perform any

unauthorized modification of the equipment. Contact your local Motorola representative for service and

repair to ensure that safety features are maintained.

Dangerous Procedure Warnings.

Warnings, such as the example below, precede potentially dangerous procedures throughout this manual.

Instructions contained in the warnings must be followed. You should also employ all other safety

precautions which you deem necessary for the operation of the equipment in your operating environment.

PPCBug Overview

PPCBug is a powerful evaluation and debugging tool for systems 

built around the Motorola PowerPC microprocessors. PPCBug 

firmware consists of three parts:

❏ Command-driven user-interactive software debugger. It is 

hereafter referred to as the debugger, which is described in this 

manual. Debugging commands are available for loading and 

executing user programs under complete operator control for 

system evaluation. 

❏ Command-driven diagnostic package for testing and 

troubleshooting the PowerPC board, which is hereafter called 

the diagnostics. Refer to the PPC1Bug Diagnostics Manual.for 

information on the diagnostics and the diagnostics utilities 

and self-tests.

❏ MPU, firmware, and hardware initialization routines, which 

are described in this manual.

The PPCBug firmware is implemented on the following Motorola 

PowerPC-based products:

❏ MVME230x VME Processor Modules

❏ MVME260x Single Board Computers

❏ MVME3604 VME Processor Modules

❏ MVME4604 VME Dual Processor Modules

❏ MTX Embedded ATX Motherboards

❏ MCP750 PowerPC Single Board Computers

A PMCspan board added to any of these also interfaces with PPCBug.

They are collectively referred to in this manual as the PowerPC board
