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.

1.2 What’s next?

To get started on evaluating the OMAP35x Graphics capabilities and developing applications using the

SGX accelerator for OMAP35x EVM, begin by using this Getting Started guide. It is suggested that the

user follow the sequence described in the document. The sequence is outlined below.

•OMAP35x DVEVM Software Setup for Graphics SDK

•Executing the Graphics SDK Demonstration Software

•Building the NFS Target File System with Graphics SDK Demos

•Building the OMAP35x Graphics Demo Software

•Building the Graphics Kernel Modules

1.3 Command Prompts in this Guide

In this guide, commands are preceded by prompts that indicate the environment where the command is

to be typed. For example:

•host $

Indicates command to be typed into the shell window of the host Linux workstation.

•OMAP3EVM #

Indicates commands to be typed into the U-Boot shell in a console window connected to the EVM

board's serial port.

•target $

Indicates commands to be typed into the Linux shell in the terminal window connected to the

EVM board's serial port.

1.4 Updates & Further information

Please be sure to register your EVM at:
