Section 1
Overview
1.1 Scope The AT91EB42 Evaluation Board enables real-time code development and evaluation.
It supports the AT91M42800.
This guide focuses on the AT91EB42 Evaluation Board as an evaluation and demon-
stration platform:
Section 1 provides an overview.
Section 2 describes how to set up the evaluation board.
Section 3 details the on-board software.
Section 4 contains a description of the circuit board.
Section 5 and Section 6 are two appendices covering configuration straps and
schematics, including pin connectors.
1.2 Deliverables The evaluation board is delivered with a DB9 plug-to-DB9 socket straight-through serial
cable to connect the target evaluation board to a PC. A bare power lead with a 2.1 mm
jack on one end for connection to a bench power supply is also delivered.
The evaluation board is also delivered with a CD-ROM that contains an evaluation ver-
sion of the 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 AT91EB42
Getting Started Tutorial documents for recommendations on using the evaluation board
in a full debug environment.
