TI's OMAP Linux website has goodies including:
- 2.6.8-rc3_080804.tar.bz2
- a relatively old snapshot of the 2.6 OMAP kernel (warning: ~150MB download)
- u-boot binaries and source - note that old versions use the Innovator-1510 board id, but U-Boot 1.1.2 should is used with 2.6
- rootfsosk.tar.bz2

For current code (2.6.13-rc1-omap1 at this edit) install GIT and run the following command:
-
git clone git://source.mvista.com/git/linux-omap-2.6.git- (This might take a while, the tree is big)
- or just get OMAP-Linux patches less current than the linux-omap GIT tree, against various older http://kernel.org kernels
- you might be able to use kernel.org kernels directly, but some important drivers haven't yet made it upstream

Use buildroot to quickly make a toolchain and rootfs

TODO list
- Flash Recovery Utility (FRU) available above is uses an undocumented usb interface and is only for windows
- Zach Welch wants the protocol specs so a scriptable version can be created for Linux
- GPL'd OMAP Flash Loader listed above duplicates the protocol, but does not document it.
- u-boot sources with correct arch number (515 as listed on http://www.arm.linux.org.uk/developer/machines/) should be available from http://u-boot.sourceforge.net; or use u-boot 1.1.1 with Media:u-boot-1.1.1-osk.diff
- OE should build complete flash image
- uClibc rootfs should be available
- find/post patch info for 2.4 (2.6 is listed above)
- Tim Riker thinks it would be nice to have a uclibc/tuxscreen style buildroot too. ;))
