The Gumstix Overo COM is supported by the Linaro Project. Linaro is not a distribution but really an effort to make a common framework for unleashing open-source software on embedded systems. The Linaro project is backed by Canonical (the people behind Ubuntu) among others which means this is a great place to start if you want to run Ubuntu on your Overo COM.

Getting the Images

Gumstix is scheduled for inclusion in the next Linaro release due in May 2011. As of Mar 2011, an Alpha 3 release is available although you will want to use the daily snapshots for the most up-to-date fixes. You'll need two components:

Getting the Tools

linaro-media-create is a tool to automatically create a bootable microSD for your Overo. For those running Ubuntu Natty, apparently this will do the trick:

sudo apt-get install linaro-image-tools

For those sporting Maverick (10.10) (and older?) :

sudo add-apt-repository ppa:linaro-maintainers/tools
sudo apt-get update 
sudo apt-get install linaro-image-tools
sudo apt-get install qemu-user-static

More details are available here

Making a Card

The final step is actually creating the microSD card. Navigate to the directory where you downloaded the image and the hardware pack, slip a microSD card into your machine, and issue a command like this:

sudo linaro-media-create --rootfs ext3 --mmc /dev/mmcblk0 --binary linaro-n-ubuntu-desktop-tar-20110314-0.tar.gz --hwpack hwpack_linaro-overo_20110314-0_armel_supported.tar.gz --dev overo

Notes:

  • use dmesg to check that your SD card is actually /dev/mmcblk0 before doing this
  • the --binary argument will depend on which image you chose to download

This command will take a little while to download any extra bits it needs and format your card. For me, this was about 20 minutes total and I waited a long time on the 'Populating rootfs partition' step. Once it is done, unmount the card and slide it into your Overo COM and power on as normal.
