Introduction

This is Release 03.20.00.08 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-L137 and OMAP-L138 EVMs. 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)
DaVinci Linux Kernel	2.6.32-rc6 (Linux kernel version)	http://git.kernel.org/?p=linux/kernel/git/khilman/linux-davinci.git;a=summary	d9d2b372d8641f93720da204a6a756e789e83590
U-Boot	2009.08	http://git.denx.de/?p=u-boot.git;a=summary	v2009.08

The File system is based on the Arago, version 2009.09.

The codebase for Linux kernel and U-Boot included in this release is also hosted at the following publicly visible repositories:

Component	Repository	Baseline Tag	Release Tag
DaVinci Linux Kernel	http://arago-project.org/git/people/?p=sekhar/linux-omapl1.git	v2.6.32-rc6-03.20.00.08-baseline	REL_DAVINCIPSP_03.20.00.08_beta
U-Boot	http://arago-project.org/git/people/?p=sekhar/u-boot-omapl1.git	v2009.08	REL_DAVINCIPSP_03.20.00.08_beta

The Baseline Tag is applied to the commit from Kevin Hilman's DaVinci GIT tree based on which this release was made. The Release Tag should be used to access the source tree corresponding to the release.

For detailed information on the various software components included in the release and how to use them, please refer to the User's Guide.

The kernel and U-Boot have been compiled with CodeSourcery GNU Toolchain for ARM Processors 2009-q1-203 based on GCC 4.3.3

Installation and Usage

Please look for detailed installation and usage instructions in 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 any incompatibility with previous version.

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 DA830/OMAP-L137 and DA850/OMAP-L138 Evaluation Modules (EVMs).

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 03.20.00.08 of DaVinci PSP SDK product.
