== How to get the Ubuntu distribution ==
The Ubuntu project is excited to be working with the ARM ecosystem to port Ubuntu for ARM-based devices. This work fits with our goals of making Ubuntu available as an open platform to as many people as possible. Some points to note:
== Overview Requirements==* A SD card at least 2GB ( recommended 4GB ) ==References==Much of this How-To is extracted from different sources. If you would like to read some of the original articles or resources, please visit them and thank the authors: * The Ubuntu website ( http://www.ubuntu.com )* Ubuntu on ARM ( http://www.ubuntu.com/products/whatisubuntu/arm )* The rootstock project ( https://launchpad.net/project-rootstock )* ARM rootfs from scratch ( https://wiki.ubuntu.com/ARM/RootfsFromScratch ) ==Ubuntu releases====Releases==['''TIP'''] If you want to install the ubuntu image you should install the ubuntu rootfs and use the ISEE kernel and bootloader. ['''IMPORTANT'''] ISEE is not responsable about the Ubuntu releases you should read the information about Ubuntu deprecation releases in the Ubuntu webpage. ===Ubuntu 12.04.4 LTS (for IGEPv2, IGEP COM MODULE ISEE devices)===IGEPv2, IGEP COM Module and IGEP COM Proton Ubuntu page is located [[IGEPv2 Ubuntu Distro|here]] ===Ubuntu 12.04.4 LTS Hard Float (for IGEPv5)===IGEPv5 Ubuntu page is located [[IGEPv5 Ubuntu Distro|here]] ===Ubuntu 14.04 Lxde (for IGEP iMX6)===IGEP iMX6 Ubuntu page is located [[IGEP iMX6 Ubuntu Distro|here]] ===Ubuntu Base Firmware (All Boards)===Ubuntu base page is located [[IGEP Firmware Ubuntu|here]] ==Old Releases=====Ubuntu 10.10 (Maverick Meerkat)===First, download the compressed image from http://cdimage.ubuntu.com/ubuntu-netbook/ports/releases/ wget http://cdimage.ubuntu.com/ubuntu-netbook/ports/releases/maverick/release/ubuntu-netbook-10.10-preinstalled-netbook-armel+omap.img.gz Next, uncompress the image with gunzip ubuntu-netbook-10.10-preinstalled-netbook-armel+omap.img.gz Then write the raw image to a blank SD card (the card size should be >2G) sudo dd if=<uncompressed image> of=/dev/mmcblk0 # change /dev/mmcblk0 with appropriate device Current boot file system (x-loader + u-boot + kernel) not works, so we need to replace.

===Ubuntu 9.04 (Jaunty Jackalope)===
====Make a bootable MMC card on Linux====
Thanks to Graeme Gregory and Steve Sakoman, you can now use [http://www.sakoman.com/OMAP3/a-script-for-partitioningformatting-a-bootable-sdmicrosd-card.html a script to automate the tedious process of creating a bootable SD/microSD card.]
bootm 80200000
And use the mkimage tool to convert this file into a script image which can be executed using U-Boot's source command.
$ source /usr/local/poky/eabi-glibc/arm/environment-setup
$ mkimage -A arm -O linux -T script -C none -a 0 -e 0 -n 'Boot setup script' -d boot-ini.source boot.ini
If you are not using IGEP's virtual machine, you can download and install the Poky SDK from http://www.igep.es/index.php?option=com_content&view=article&id=99&Itemid=112&dir=/var/www/vhosts/igep.es/httpdocs/downloads/01-ISEE_Products/IGEPv2/SW_Releases/poky/purple-3.2/v3.2.1-0/sdk once logged in. This will provide the /usr/local/poky directory. If you use this option, the appropriate source command is <tt>source /usr/local/poky/eabi-glibc/environment-setup-arm-none-linux-gnueabi</tt>.
The result will be a boot.ini file which you will copy to SD card boot partition
$ cp boot.ini /media/boot
== Ubuntu releases == Get a copy of a ARM ubuntu root file system=== Ubuntu 9.04 (Jaunty Jackalope) === 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.
$ sudo apt-get install qemu
$ 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
--seed lxde,gdm
Next, mount your SD card ext3 partition (/media/rootfs) and untar the rootfs
Finally, umount the SD card, insert the card in your board and power up.
