AT91EB55 Evaluation Board User Guide

1-1

Section 1

Overview

1.1

Scope

The AT91EB55 Evaluation Board enables real-time code development and evaluation.

It supports the AT91M55800A.

This user guide focuses on the AT91 Evaluation Board as an evaluation and demonstra-

tion platform:

Section 1 provides an overview.

Section 2 describes how to setup the evaluation board.

Section 3 describes the on-board software.

Section 4 contains a description of the circuit board.

Appendixes A and B cover configuration straps and schematics including pin

connectors.

1.2

Deliverables

The evaluation board is supplied with a DB9 plug to DB9 socket straight through serial

cable to connect the target evaluation board to a PC. There is also a bare power lead

with a 2.1 mm jack on one end for connection to a bench power supply.

The evaluation board is also delivered with a CD-ROM that contains an evaluation ver-

sion of Software Development Toolkit and the documentation that outlines the AT91

microcontroller family.

The evaluation board is capable of supporting different kinds of debugging systems

using an ICE interface or the on-board Angel™ Debug Monitor. Refer to the EB55 “Get-

ting Started” tutorial documents for recommendations on using the evaluation board in a

full debugging environment.
