OMAP 5912 Starter Kit

OMAP5912 Starter Kit is a development board available from Spectrum Digital for $US295. It does not include a display but there is a Q-VGA LCD Module (below) and a Wire Wrap Prototyping Module

LCD Modules

Q-VGA from Mistral

Mistral Software Q-VGA LCD Module for OMAP5912 Starter Kit.

Note: a hardware modification is required to use the wakeup button.

    • How to Build Linux for the OMAP5912 Processor

• 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

• Execute kernel in place (XIP) from flash Kernel XIP

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. ;))
