Introduction

This is Release 03.00.01.06 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:

Component	Repository (Branch)	Baseline Tag	Release Tag
OMAP Linux Kernel	http://arago-project.org/git/projects/?p=linux-omap3.git;a=summary (OMAPPSP_03.00.01.06)	OMAPPSP_03.00.01.06_baseline	v2.6.32_OMAPPSP_03.00.01.06

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.

What's Supported

SDK package includes support for AM3517 platform(AM3517EVM), OMAP35x platforms(OMAP3EVM). Support for AM/DM37x has been included as part of this release.

OMAP35x and AM/DM37x are binary compatible(same x-loader,u-boot,kernel binaries can be used) - differences are handled through run time detection.

The SDK package supports the following components:

• U-Boot supporting NAND, MMC boot modes
• X-loader supporting NAND, MMC boot modes
• Linux Kernel and device drivers.
  • Audio (McBSP)
  • Video Display (V4L2 and Fbdev)
  • Video Capture (BT656 mode)
  • Video Resizer (Only on OMAP35x, AM/DM37x)
  • Ethernet
  • MUSB host supporting MSC, HID and USB Audio/Video
  • MUSB gadget supporting File-storage and CDC/RNDIS
  • MUSB OTG supporting HNP/SRP
  • EHCI host supporting MSC, HID(via a HS hub) and USB Audio/Video
  • NAND
  • MMC/SD/SDIO
  • UART
  • I2C
  • TouchScreen
  • SPI
  • RTC
  • WDT
  • Keypad
  • CAN - SocketCAN implementation (on AM3517)
  • Power Management ICs (TPS65023 on AM3517, TPS65950 on OMAP35x, AM/DM37x)
    
• Audio and video examples.
• Pre-built binaries for X-loader, U-Boot, Linux kernel and filesystem.

Important
For OMAP35x, the U-boot pre-built binaries support Micron NAND part only. For older OMAP35x EVM with OneNAND parts, the u-boot binary needs to be re-built with OneNAND support. Please refer the Getting Started Guide for detailed instructions

For AM/DM37x, Rev.C Processor card with Hynix memory part is supported. Older versions with Micron Memory part are not supported with this release

What's Not Supported

• Following are not supported:
  • U-boot (Unified binary supporting Nand/OneNand on OMAP35x platform)
  • NOR support (on AM3517EVM)
  • AM/DM37x Processor card with Micron Memory
