== 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 of How-To==This How-To is meant to be a starting point for people to learn install an Ubuntu will target the new ARM EABIimage for OMAP3-based IGEP platforms as quickly and easily as possible. ==Requirements==*For nowA 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, builds will expect a minimum of an ARMv5 instruction setplease visit them and thank the authors: * The Ubuntu website ( http://www.ubuntu.com )*Ubuntu will target on ARM with VFP (Vector Floating Pointhttp://www.ubuntu.com/products/whatisubuntu/arm )* The rootstock project ( https://launchpad.net/project-rootstock )*We will continue ARM rootfs from scratch ( https://wiki.ubuntu.com/ARM/RootfsFromScratch ) ==Ubuntu releases====Releases==['''TIP'''] If you want to work with vendors to provide hardware drivers 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 various ARM-based 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 will likely have 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 different set blank SD card (the card size should be >2G) sudo dd if=<uncompressed image> of kernels than Debian =/dev/mmcblk0 # change /dev/mmcblk0 with appropriate device Current boot file system (although the specific set is still under discussionx-loader + u-boot + kernel)not works, so we need to replace.First download and extract this package

Take care if you do not have your system in English. You have to change Activate the word "Disk" in the former scriptuniverse and multiverse repositories, line #10 with the translation in then install the language of your system.following packages:
Having followed this excellent tutorial it's time to mount your SD card boot partition (/media/boot). With your preferred editor create a boot sudo apt-ini.source file like this.get install libegl1-sgx-omap3 libgles1-sgx-omap3 libgles2-sgx-omap3
# Set bootargs for ubuntu MMC boot setenv bootargs Before using it just be sure your user is also included at 'console=ttyS2,115200n8 console=tty0 omapfb.mode=dvi:1024x768MR-16@60 root=/dev/mmcblk0p2 rw rootwait video' # Read kernel from OneNAND onenand read 80200000 280000 400000 # and boot ..group. 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. sudo adduser <your user> video

The result will be a boot...ini file which you will copy to SD card boot partition

====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.
$ 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
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.
Next, mount your SD card ext3 partition (/media/rootfs) and untar the rootfs
