Introduction[edit]
This release notes document applies to version 04.02.00.07 of OMAP Linux PSP. It summarizes features supported, known issues and workarounds applicable to the supported platforms - AM3517EVM, OMAP3EVM (OMAP35x, AM/DM37x) and BEAGLE (OMAP35x & AM/DM37x).
Important
This release has undergone complete system test on AM37x EVM (with ES1.2) and AM3517EVM (with ES1.2). It has only been sanity tested on OMAP35x EVM and Beagle/ BeagleXM platforms.
Read This First[edit]
Upstream changes across components (x-loader, u-boot and Linux kernel) have an impact on the usage - as compared to the previous releases. Important changes are being highlighted here. More details (if necessary) are appropriately included in the User Guide.
Important
- The NAND driver in Linux kernel now uses 1-bit hardware ECC. The x-loader and u-boot have been updated to use same ECC scheme.
- It is, therefore, mandatory to update the x-loader and u-boot when using the Linux kernel from this release. Filesystem residing on the NAND partition will need to be re-flashed as well.
- See detailed procedure in the User Guide
- The serial console device has been renamed ttyOn (from ttySn).
- This impacts the bootargs passed to the kernel and console definition in the /etc/inittab of existing filesystems.
- See section Using The Correct Console Device in the User Guide
- When using NFS location for root filesystem, the DHCP script included in the filesystem may need to be changed.
- See section Updating the DHCP Script in the User Guide
- List of parameters passed to create the JFFS2 image via mkfs.jffs2 have changed.
- See section Creating JFFS2 File-system in the User Guide
- The steps for flashing the JFFS2 image to NAND from u-boot have changed.
- See section Flashing File-system from U-Boot in the User Guide
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 | 2.6.37(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 | 2b3ea6aa16956e15f1ba8e7b70898aaacbec2237. History on "pm" branch gets rewritten and hence the commit may not be valid always. |
| U-Boot | 2010.06 | http://git.denx.de/?p=u-boot.git;a=summary | v2010.06 |
The File system is based on the Arago.
The codebase for X-loader, U-Boot and Linux kernel included in this release is also hosted at the following repositories:

The kernel and U-Boot have been compiled with CodeSourcery GNU Toolchain for ARM Processors 2009-q1-203 based on GCC 4.3.3
Obtaining the Release Package[edit]
The PSP release package can be obtained from TI's Technology and Software Publicly Available (TSPA) download site.
Documentation[edit]
- The User Guide provides instructions on how to use this Linux PSP.
- The Feature Performance Guide provides performance benchmarks on select drivers included with the PSP package.
A copy of both these documents is also included in the docs folder inside the release package.
What's Supported[edit]
This Linux PSP includes support for AM3517 platform(AM3517EVM), OMAP35x platforms(OMAP3EVM, Beagle) and AM/DM37x platforms (OMAP3EVM, BEAGLEXM).
OMAP35x and AM/DM37x are binary compatible(same X-loader, U-boot, Kernel binaries can be used) - differences are handled through run time detection.
This Linux PSP supports the following components:
- U-Boot supporting NAND, MMC and NOR (only on AM3517)boot modes
- X-loader supporting NAND, MMC and NOR (only on AM3517) boot modes
- Linux Kernel and device drivers.
- Audio (McBSP)
- Video Display (V4L2 and Fbdev)
- Video Capture (YUV and BT656 mode)
- Ethernet
- NAND
- NOR (on AM3517)
- 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)
- MUSB host supporting MSC, HID and USB Audio/Video
- MUSB gadget supporting File-storage and CDC/RNDIS
