How to get the Linaro distribution

How to get the Linaro distribution

Linaro™ brings together the open source community and the electronics industry to work on key projects, deliver great tools, reduce industry wide fragmentation and provide common foundations for Linux software distributions and stacks to land on.

Overview of How-To

This How-To is meant to be a starting point for people to learn install a Linaro image for OMAP3-based IGEP platforms as quickly and easily as possible.

Unless otherwise noted, this How-To works with the Ubuntu 10.10 but most of the contents are valid also for other GNU/Linux distributions. We do not issue any guarantee that this will work on other distributions.

Linaro releases

Linaro 10.11 (snapshot 20101022)

WORK IN PROGRESS, PLEASE CONTRIBUTE

Install needed packages, on Ubuntu

sudo apt-get install uboot-mkimage uuid-runtime realpath

Workdir

mkdir linaro
cd linaro

download latest linaro-media-create to a location in your PATH, e.g. $HOME/bin/:

bzr branch lp:linaro-image-tools
cp linaro-image-tools/linaro-media-create $HOME/bin

Use dlimage script to download the image files and verify the sha1sums.

wget http://people.canonical.com/~plars/linaro/dlimage
chmod +x dlimage

./dlimage http://snapshots.linaro.org/10.11-daily/linaro-alip/20101022/0/images/tar

cd image

Now it's time to get a hardware pack for the IGEP board. (For now the hardware packs are only available on the Hudson instance running on jameswestby.net, but soon we should have them mirrored somewhere on linaro.org)

wget http://jameswestby.net:8080/view/Hardware%20Packs/job/linaro-igep%20hwpack/lastSuccessfulBuild/artifact/hwpack_linaro-igep_20101021-23_armel.tar.gz

Next plug in your SD card and ensure you know the device node for your sd card reader. We are assuming device node of /dev/mmcblk0, run linaro-media-create

linaro-media-create --rootfs ext3 --mmc /dev/mmcblk0 --dev igep --binary linaro-m-alip-tar-20101022-0.tar.gz --hwpack hwpack_linaro-igep_20101021-23_armel.tar.gz

Finally, plug the SD card in your board and boot.
