GSG: OMAP35x DVEVM Overview

^ Up to main OMAP35x DVEVM Getting Started Guide Table of Contents

This Chapter introduces the OMAP35x DVEVM (Digital Video Evaluation Module).

What’s in the kit?

The OMAP35x DVEVM kit comes with the following hardware items. EVM Hardware Setup tells how to connect these components.

• OMAP35x™ EVM Target Board

• Includes dual-mode touch screen LCD display and stylus

• USB cable
• Serial Cable
• Universal Power supply and power cords. Both U.S. and European style power cables are provided

The kit comes with the following printed documentation:

• OMAP35x™ DVEVM Installation and Registration Instructions
• OMAP35x DVEVM Setup Guide
• Mistral OMAP35x DVEVM Hardware User’s Guide
• OMAP35x DVEVM Getting Started Guide (this document)

The kit comes with the following software CDs. The information on how to use these software components are provided in OMAP35x DVEVM Software Setup

• CD 1: OMAP3530 DVSDK (Digital Video Software Developer’s Kit)
• CD 2: Audio/Video files used by the OMAP3530 DVSDK demonstration software.
• CD 3: Sourcery G++™ evaluation tools from CodeSourcery

Installation and use of the Software Development Kit is described in this document. This document assumes the use of the LITE version of CodeSourcery tools. This version is an unrestricted command line toolchain available free of charge from the CodeSourcery web site (see section Installing the Toolchain)

Alternatively, a full featured IDE 30 Day time limited version of Sourcery G++ is provided. To install and use the evaluation version of CodeSourcery’s Sourcery G++ product, please see the information available on the provided CD.

Identifying Board Variations

There are two variations of the OMAP35x EVM board that have been produced. The following section will help you identify the board you are working with.

The difference in the board variations is the memory used. Both configurations use the package on package configuration, which places the memory part on top of the OMAP processor. The following table shows the key differences.

Different settings are used for the main boards SW4 switch for the two board variations. The switch setting adjusts the SYS_BOOT signals to the OMAP processor that select the boot processing performed by the OMAP Boot-ROM. In addition, the other system software (x-loader, u-boot, Linux kernel) uses these switch settings to identify which type of memory is used on the board.

What’s on the board?

The following block diagram shows the major hardware components.

NOTE: TWL4030 will be replaced with TPS65950 for mass production. These devices are pin and software compatible.

What’s next?

To get started evaluating the DVEVM kit and developing applications for the OMAP35x, 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.

EVM Hardware Setup	Connect the various cables and other basic hardware setup
Running the DVSDK Demonstration	Run the demonstration application that comes with the OMAP3530 DVSDK
OMAP3530 DVSDK Software setup	Setup the development hosts using the OMAP3530 DVSDK installer files and the compiler toolchain
Rebuild software	Rebuild various aspects of the supplied target software
Re-install the target software	Use the supplied, known good software images to re-flash the EVM.
Develop with the OMAP35x EVM board	The final section covers additional operation information on using your OMAP35x EVM board
