MOTLoad Firmware
Introduction
This chapter describes the basic features of the MOTLoad firmware product, designed by
Motorola as the next generation initialization, debugger, and diagnostic tool for high-
performance embedded board products using state-of-the-art system memory controllers and
bridge chips, such as the MPC8540 processor.

In addition to an overview of the product, this chapter includes a list of standard MOTLoad
commands, the default VME and firmware settings that are changeable by the user, remote
start, and the alternate boot procedure.

Overview
The MOTLoad firmware package serves as a board power-up and initialization package, as well
as a vehicle from which user applications can be booted. A secondary function of the MOTLoad
firmware is to serve in some respects as a test suite providing individual tests for certain
devices.

MOTLoad is controlled through an easy-to-use, UNIX-like, command line interface. The
MOTLoad software package is similar to many end-user applications designed for the
embedded market, such as the real time operating systems currently available.

MOTLoad Implementation and Memory Requirements
The implementation of MOTLoad and its memory requirements are product specific. The
MVME3100 single-board computer (SBC) is offered with a range of memory (for example,
DRAM or flash). Typically, the smallest amount of on-board DRAM that a Motorola SBC has is
32MB. Each supported Motorola product line has its own unique MOTLoad binary image(s).
Currently the largest MOTLoad compressed image is less than 1MB in size.

MOTLoad Commands
MOTLoad supports two types of commands (applications): utilities and tests. Both types of
commands are invoked from the MOTLoad command line in a similar fashion. Beyond that,
MOTLoad utilities and MOTLoad tests are distinctly different.
