== 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 x-loader + u-boot + kernel) not works, so we need to replace. First download and extract this package wget https://edge.launchpad.net/ubuntu/+source/linux/2.6.35-22.33/+buildjob/1970697/+files/linux-image-2.6.35-22-omap_2.6.35-22.33_armel.deb ar -x linux-image-2.6.35-22-omap_2.6.35-22.33_armel.deb tar jxf data.tar.bz2 sudo cp -fr boot lib usr /media/<rootfs> # change <rootfs> with appropriate SD rootfs partition then, create an uImage file with mkimage -A arm -O linux -T kernel -C none -a 0x80008000 -e 0x80008000 -n "Linux" -d boot/vmlinuz-2.6.35-22-omap uImage cp uImage /media/<bootfs> # change <bootfs> with appropriate SD boot partition next, download and copy x-loader from wget http://downloads.isee.biz/pub/SW_Releases/binaries/x-loader/v1.4.4-3/x-load-1.4.4-3.igep0020-sdcard.bin.ift cp x-load-1.4.4-3.igep0020-sdcard.bin.ift /media/<bootfs>/MLO # change <bootfs> with appropriate SD boot partition and finally, do the specific set same with u-boot wget http://downloads.isee.biz/pub/SW_Releases/binaries/u-boot-arm/v2010.06-3/u-boot-arm-2010.06-3.igep0020.bin cp u-boot-arm-2010.06-3.igep0020.bin /media/<bootfs>/u-boot.bin # change <bootfs> with appropriate SD boot partition The last step is copy boot.scr to boot.ini cp /media/<bootfs>/boot.scr /media/<bootfs>/boot.ini # change <bootfs> with appropriate SD boot partition Umount bootfs and rootfs partitions, push your SD card in your IGEP socket, power up and enjoy ! ====System Testing and known issues====* Can't bring up eth0, no network - this is a known issue that has been fixed but may not have been applied yet.** https://bugs.launchpad.net/ubuntu/+source/linux/+bug/645689 (see tips and tricks for solution) ====Tips and tricks=========Upgrade kernel to 2.6.35-23=====Note: This solves the eth0 issue. Donwload and copy the 2.6.35-23 kernel wget http://downloads.igep.es/ubuntu/maverick/linux-image-2.6.35-23-omap_2.6.35-23.40_armel.deb sudo cp linux-image-2.6.35-23-omap_2.6.35-23.40_armel.deb /media/<rootfs> # change <rootfs> with appropriate SD rootfs partition Boot up your Ubuntu , open a terminal and install sudo dpkg -i linux-image-2.6.35-23-omap_2.6.35-23.40_armel.deb Reboot your system, now the ethernet an wifi should work. '''Note:''' Some users have encountered that after kernel update still booting the old kernel, to solve this issue do: mkimage -A arm -O linux -T ramdisk -C none -a 0 -e 0 -n initramfs -d /media/<rootfs>/boot/initrd.img-2.6.35-23-omap /media/<bootfs>/uInitrd mkimage -A arm -O linux -T kernel -C none -a 0x80008000 -e 0x80008000 -n 2.6.35-23-omap -d /media/<rootfs>/boot/vmlinuz-2.6.35-23-omap /media/<bootfs>/uImage =====How to get SGX Video Acceleration (under discussionconstruction, not tested yet)=====src: https://wiki.ubuntu.com/ARM/OMAP/Graphics First we'll install kernel headers wget http://downloads.igep.es/ubuntu/maverick/linux-headers-2.6.35-23-omap_2.6.35-23.40_armel.deb sudo dpkg --install --force-depends linux-headers-2.6.35-23-omap_2.6.35-23.40_armel.deb Activate the universe and multiverse repositories, then install the following packages:

Unless otherwise noted, this How-To works with the '''Ubuntu 8.04 IGEP v2.0 SDK Virtual MachineBefore using it just be sure your user is also included at 'video'' 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 distributionsgroup.
This How-To will start out by a '''Make a bootable MMC card on Linux'''. sudo adduser <your user> video
And thenNow you can test the SGX with a DEMO, we will cover grab and untar the '''Getting a copy of a ubuntu root file system''' for various Ubuntu releases. These should give you a good basis overview of creating an ubuntu-based ARM root filesystem.SDK Demo Package
== Requirements == wget http://neuvoo.org/neuvoo/distfiles/SGX-3.01.00.07-SDK.tar.gz*A SD card at least 2GB ( recommended 4GB ) tar xzf SGX-3.01.00.07-SDK.tar.gz

===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
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
Finally, umount the SD card, insert the card in your board and power up.
=== Ubuntu 10.10 (Maverick Meerkat BETA) === First, download the compressed image from http://cdimage.ubuntu.com/ubuntu-netbook/ports/releases/ wget http://cdimage.ubuntu.com/ubuntu-netbook/ports/releases/maverick/beta/ubuntu-netbook-10.10-beta-preinstalled-netbook-armel+omap.img.gz Next, uncompress the image with gunzip ubuntu-netbook-10.10-beta-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 Remove all file but uImage from /media/rootfs and create a boot.source file like this setenv bootcmd 'mmc init; fatload mmc 0:1 0x80300000 uImage; bootm 0x80300000' setenv bootargs 'mem=512M console=ttyS2,115200n8 console=tty0 omapfb.mode=dvi:1024x768MR-16@60 root=/dev/mmcblk0p2 rw rootwaitThat' boot create the boot.ini with $ mkimage -A arm -O linux -T script -C none -a 0 -e 0 -n 'Boot setup script' -d boot.source boot.ini I have only an ethernet cable, so I'm going on. Put these lines in /media/rootfs/etc/rc.local : <br> <pre>apt-get install -y openssh-server 2>&1 | tee /root/install.loguseradd -G admin,root -s /bin/bash all folks -m igepecho "igep:igep" | chpasswdexit 0</pre> Check /etc/interfaces for "auto eth0", then boot the board with ethernet cable and wait some minutes. You can verify sshd status for example with (I've used a mac so nmap may differ):<br> <pre>sudo nmap -sS -PN -e <interface> -p22 <ip></pre>If you prefer passwordless ssh key authentication, create a key with ssh-keygen and copy the content of your .ssh/id_rsa.pub in authorized_keys :<br> <pre>* ON THE IGEP *$ cd /media/rootfs/home/igep$ mkdir .ssh$ chmod 700 .ssh$ touch authorized_keys$ chmod 600 authorized_keys$ cat /wherever/it/is/your's/id_rsa.pub >> authorized_keys</pre> Remember to enable PubkeyAuthentication in /media/rootfs/etc/ssh/sshd_config :<br> <pre>PubkeyAuthentication yes</pre> ==== Minor problems<br> ==== */etc/hosts is missing and generates a sudo error
