IGEPv2 Ubuntu Distro
From IGEP - ISEE Wiki
How to get the Ubuntu 12.04.4 LTS
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.
Overview of How-To
This How-To is meant to be a starting point for people to learn install an Ubuntu image for OMAP3-based IGEP platforms as quickly and easily as possible.
This How-To covers IGEPv2, IGEP COM Module and IGEP COM Proton boards. if you are looking Ubuntu for IGEPv5 go to this other Howto.
Contents
Host Enviroment
We suggest use Ubuntu 12.04.4 LTS (32 bits) in your host, you can download it from our server using this link or directly from Ubuntu (Canonical) website. You can install it in a Virtual Machine environment using any Virtualization software or directly in your PC.
Material
- IGEPv2, IGEP COM Module or IGEP COM Proton.
- 1 MicroSD Card with 512 MiB minimum space.
- Serial Cable and conversor for attach the serial debug console.
- Ethernet cable (optional)
- Hub (optional)
- Keyboard and mouse (optional)
- HDMI/DVI Monitor (optional)
Download the Ubuntu 12.04.4 LTS Distribution and tools
The Ubuntu 12.04.4 LTS distribution can be downloaded from here or if you want to use the hard float version you should use this other link.
The first boot must be done using the first boot package, inside you've the bootloader, igep.ini and temporary kernel.
You can download this script for create the right partitions in the microsd card (Only is valid for microsd card, it cannot be used for prepare the raw Nand flash)
Prepare the Environment
Check if you've the packages bc and dosfstools
Install both packages as:
apt-get install bc dosfstools
Prepare the MicroSD card
Insert the microsd card in your host, after that you should see any similar to this output:
mcaro@mcaro-vm-u12:~$ lsblk NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT fd0 2:0 1 4K 0 disk sda 8:0 0 100G 0 disk ├─sda1 8:1 0 98G 0 part / ├─sda2 8:2 0 1K 0 part └─sda5 8:5 0 2G 0 part sdb 8:16 1 3.8G 0 disk ├─sdb1 8:17 1 70.6M 0 part /media/boot └─sdb2 8:18 1 3.7G 0 part /media/rootfs sr0 11:0 1 1024M 0 rom
here you can see the device sdb (it's the 4 GiB microsd card) be careful due in your host can be other device like sdc if you doubt check the dmesg output it should show you the device as:
[258974.855508] sd 33:0:0:0: [sdb] 7882752 512-byte logical blocks: (4.03 GB/3.75 GiB) [258974.862052] sd 33:0:0:0: [sdb] No Caching mode page found [258974.862057] sd 33:0:0:0: [sdb] Assuming drive cache: write through [258974.869338] sd 33:0:0:0: [sdb] No Caching mode page found [258974.869341] sd 33:0:0:0: [sdb] Assuming drive cache: write through [258974.871258] sdb: sdb1 sdb2 [258975.642423] EXT4-fs (sdb2): mounted filesystem with ordered data mode. Opts: (null)
Now you should execute the script prepare-disk.sh
mcaro@mcaro-vm-u12:~$ ./prepare-disk.sh fd0 2:0 1 4K 0 disk sda 8:0 0 100G 0 disk sdb 8:16 1 3.8G 0 disk Select the disk: [sdx or mmcblkx]
Here you should write the device name in our case sdb
sdb sdb Erase disk: /dev/sdb Are your sure? Y/n y
Verify the disk selected is correct if this is the situation then set Y

After finish the microsd card will be ready for install the Ubuntu the microsd card will show you two partitions, the first one formated with FAT32 and the second one formated with EXT4.
TIP: you can prepare the microsd card manually using this other howto.
TIP: If the microsd card is not mounted eject the microsd card and insert it in the microsd reader again and the system will mount it automatically or mount the card manually.
Copy the Content into the MicroSD Card
Uncompress the boot package into the boot partition (normally mounted on /media/boot)
$ cd /media/boot $ tar xvfj ubuntu-12.04.4-isee-igeo00x0-boot.tar.bz2
After uncompress the content you should see inside the /media/boot these content:
$ zImage MLO igep.ini
The default configuration is set for boot IGEPv2 board if you wish boot the IGEP COM Module or IGEP COM Proton then you must edit the file igep.ini and set the variable:
MachineID=<board id>
Where board id:
IGEP Module => 2717
IGEPv2 => 2344
IGEP COM PROTON => 3203
Save the file
Now enter into the rootfs partition (normally mounted on /media/rootfs) and uncompress the ubuntu 12.04.4 package on it as:
$ tar xvfj ubuntu-12.04.04-lts-isee-igep00x0-20140606-armel.tar.bz2
After that sync and eject the microsd card.
First Time Boot
Insert the microsd card in the IGEPv2 board (or IGEP COM Module / IGEP COM Proton)
Plug the power cord and you should see a similar boot like this:

After first boot
When the system boot (for a first time) you will see this error related to the kernel modules:
modprobe: FATAL: Could not load /lib/modules/2.6.37/modules.dep: No such file or directory
modprobe: FATAL: Could not load /lib/modules/2.6.37/modules.dep: No such file or directory
This is normal due we didn't install the kernel yet ...
login using the serial console:
username: root password: letmein
Verify the boot partition
Check the boot partition (verify that you've the boot partition mounted in the boot directory)
$ mount /dev/mmcblk0p1 on /boot type vfat (rw,relatime,fmask=0022,dmask=0022,codepage=cp437,iocharset=iso8859-1,shortname=mixed,errors=remount-ro)
if the microsd card first partition is not mounted (not show the upper message) mount it manually as
$ mount /dev/mmcblk0p1 /boot
Install the kernel package
Go to /root/packages directory
$ cd /root/packages $ dpkg -i linux-image-2.6.37_0009.isee_armel.deb $ dpkg -i igep-fw-wifi-marvell-8686_0.1_all.deb $ dpkg -i dpkg -i igep-fw-wifi-ti-wl1271_0.1_all.deb
Due the first partition uses FAT32 is not possible create symbolic links to the kernel image installed, after install the package go to /boot directory
$ cd /boot $ ls -al
