Introduction

This is Release 03.20.00.06 of DaVinci PSP Software Development Kit (SDK). The SDK serves to provide a fundamental software platform for development, deployment and execution of Linux based applications on Texas Instruments OMAP-L138 EVM. The Linux kernel and U-Boot software in this release are based on the following open source repositories:

Component	Version	Base Repository	Base Tag (or commit id)

Installation and Usage

Please look for detailed installation and usage instructions in the User's Guide

Upgrade and Compatibility Information

To upgrade to new PSP release, simply delete the old release and extract the new release in its place.

This version does not have an in-compatibility with previous versions.

Dependencies

The DaVinci PSP release depends on Code Sourcery tool chain and Code Composer Studio (CCStudio). CCStudio is needed for initial (or recovery) flashing of UBL and U-Boot (Serial Flash utility is an alternate option without having to use CCS). As long as U-Boot remains functional on the EVM, CCStudio will not be needed.

Device Support

This release supports the Texas Instruments OMAP-L138 Evaluation Module (EVM).

Validation Information

Please use the Linux Functional Test Bench (LFTB) included in the release package for validating the release. Documentation on using LFTB is included in the LFTB package itself.

Versioning

This is Release 03.20.00.06 of DaVinci PSP SDK product.
