Introduction

This is Release 03.00.00.05 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(OMAP35x, AM/DM37x). 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(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 3fd5969a81a9324b58a1c19cf510c0da97c99565. History on "pm" branch gets rewritten and hence the commit may not be valid always.
U-Boot 2009.11 http://git.denx.de/?p=u-boot.git;a=summary v2009.11

The File system is based on the Arago, version 2009.11-rc2.


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

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

Documentation

The User Guide provides instructions on how to use the PSP SDK package. A copy of the User Guide is included in the docs folder of the SDK package.

The datasheet included in the docs folder of the SDK package provides performance benchmarks on drivers included with the PSP SDK package.

Known Issues

Issue Identifier Issue headline Known Workaround(s)
SDOCM00034288 Video Display: Mirroring of RGB888 images fails Hardware issue
SDOCM00034465 Video Display: switching back and forth between ntsc and pal standard results into display corruption. Avoid disabling display when output is on TV.

SDOCM00053357 Video Display: Flicker and color corruption observed on TV Display None
SDOCM00053359 Video Display: Sharpness is reduced when image is up-scaled. Hardware behavior: Fine tuning the scaling coeff. may give better result

SDOCM00067898 <Video Display>On suspend system hangs if the display output is on TV out. This is cross dependency with MUSB, so disable MUSb from default configuration.
SDOCM00065165 MUSB (AM3517) : SRP from device is not detected by host Start session from host side where mini-A plug is inserted.
SDOCM00067556 TSC: Wake-up event is not working. None.
