Preface

About This Guide

The OMAP35x EVM is an evaluation platform that showcases the OMAP

architecture and lets users evaluate the power and performance of OMAP as

a flexible general purpose platform.

This guide gives you overview information about the board and the software

provided with the board. It is intended to be used as an introductory

document for the EVM. Other documents provide more in-depth information.

See the EVM documentation section of the release notes for a complete list

of documents that have been included with the product.

Notational Conventions

This document uses the following conventions:

Program listings, program examples, and interactive displays are shown in a mono-spaced

font. Examples use bold for emphasis, and interactive displays use bold to distinguish commands that

you enter from items that the system displays (such as prompts, command output, error messages, etc.).

Square brackets ( [ and ] ) identify an optional parameter. If you use an optional parameter, you

specify the information within the brackets. Unless the square brackets are in a bold typeface, do not

enter the brackets themselves.
