Introduction

This is Release 03.00.00.03 of OMAP 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 AM3517EVM and OMAP3EVM. 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)
OMAP Linux Kernel 2.6.32-rc5 (Linux kernel version) The baseline was chosen from "pm" branch of http://git.kernel.org/?p=linux/kernel/git/tmlind/linux-omap-2.6.git;a=shortlog;h=refs/heads/pm 25c7b64bf80176463aa741407318e0e6b21cfd71. History on "pm" branch gets rewritten and hence the commit may not be valid always.
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 repositories:

Component Repository (Branch) Baseline Tag Release Tag

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
