Overview
3MOTLoad Firmware
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 GT-64260B.
In addition to an overview of the product, this chapter includes a list of
standard MOTLoad commands and the default VME settings that are
changeable by the user, as allowed by the firmware.

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.
Refer to the MOTLoad Firmware Package User’s Manual, listed in
Appendix D, Related Documentation, for more details.

with a wide range of memory (for example, DRAM, external cache,
Flash). Typically, the smallest amount of on-board DRAM that a Motorola
SBC has is 32MB. Each supported Motorola product line has its own
