== How to get the Ubuntu distribution ==

*Ubuntu will target the new ARM EABI.==Overview of How-To==*For now, builds will expect This How-To is meant to be a minimum of starting point for people to learn install an ARMv5 instruction set.*Ubuntu will target ARM with VFP (Vector Floating Point).*We will continue to work with vendors to provide hardware drivers image for various ARMOMAP3-based devices.*Ubuntu will likely have a different set of kernels than Debian (although the specific set is still under discussion)IGEP platforms as quickly and easily as possible.

=== Overview of How-To =Requirements==This How-To is meant to be a starting point for people to learn install an Ubuntu image for IGEP v2 devices as quickly and easily as possible.* A SD card at least 2GB ( recommended 4GB )

$ cp boot.ini /media/boot === Getting =Get a copy of a ARM ubuntu root file system ====In order to get a copy of a ARM ubuntu root file system, you will need to install qemu and a recent version of debootstrap and the qemu package. On some systems you may also need the qemu-kvm-extras package to run the ARM emulation.

In order to $ sudo apt-get a copy of a ARM ubuntu root file system, you will need to install qemu and a recent version of debootstrap and the qemu package<pre> $ sudo apt-get install qemu-kvm-extras $ wget http://ports.ubuntu.com/pool/main/d/debootstrap/debootstrap_1.0.12_all.deb $ sudo dpkg -i debootstrap_1.0.12_all.deb</pre>

<pre> $ wget http://launchpad.net/project-rootstock/trunk/0.1/+download/rootstock-0.1.3.tar.gz $ tar xzf rootstock-0.1.3.tar.gz $ cd rootstock-0.1.3</pre>

<pre> $ sudo ./rootstock --fqdn ubuntu --login jdoe --password letmein --imagesize 3G --seed ubuntu-desktop --dist jaunty</pre>

After few This step can take a long time. For example, building ubuntu-desktop on a Celeron 1.6GHz laptop takes approximately 10 hours. When it is finished, a file named armel-rootfs-[date].tgz will be in your working directory.

<pre> $ sudo tar xzf armel-rootfs-[date].tgz -C /media/rootfs</pre>
