Using the Monitor/Debug Firmware
The MPC564EVB single board computer has a resident firmware package that provides a
self-contained programming and operating environment. The firmware, named dBUG, provides
the user with monitor/debug interface, inline assembler and disassembly, program download,
register and memory manipulation, and I/O control functions. This chapter is a how-to-use
description of the dBUG package, including the user interface and command structure.
3.1 What Is dBUG?
dBUG is a traditional ROM monitor/debugger that offers a comfortable and intuitive command
line interface that can be used to download and execute code. It contains all the primary features
needed in a debugger to create a useful debugging environment.
The firmware (stored in the upper 1MByte of the Flash ROM device) provides a self-contained
programming and operating environment. dBUG interacts with the user through pre-defined
commands that are entered via the terminal. These commands are defined in Section 3.4,
“Commands”.
The user interface to dBUG is the command line. A number of features have been implemented to
achieve an easy and intuitive command line interface.
dBUG assumes that an 80x24 character dumb-terminal is utilized to connect to the debugger. For
serial communications, dBUG requires eight data bits, no parity, and one stop bit, 8N1 with no flow
control. The default baud rate is 19200 but can be changed after the power-up.
The command line prompt is “dBUG> “. Any dBUG command may be entered from this prompt.
dBUG does not allow command lines to exceed 80 characters. Wherever possible, dBUG displays
data in 80 columns or less. dBUG echoes each character as it is typed, eliminating the need for any
“local echo” on the terminal side.
In general, dBUG is not case sensitive. Commands may be entered either in upper or lower case,
depending upon the user’s equipment and preference. Only symbol names require that the exact
case be used.
