ARM/Creating ARM image using MeeGo Image Creator

Revision as of 16:20, 24 June 2011

Requirements

 * Fedora 12/13/14, Ubuntu 10.10 or other mic compatible linux distribution.
 * Required tools, e.g., qemu-arm-static, btrfs-progs and uboot-tools
 * MeeGo Image Creator tool from MeeGo tools repository

Fedora 12/13

Insert the suitable .repo file for you system from: http://repo.meego.com/MeeGo/tools/repos/fedora/ to /etc/yum.repos.d/

This is likely now broken as the F11 repository is now empty.

For fedora 12 and later, install the qemu-arm-static from Fedora 11 repository:

sudo rpm -Uvh http://repo.meego.com/MeeGo/tools/repos/fedora/11/i386/qemu-arm-static-0.12.3-1.2.i386.rpm

Install the required package:

sudo yum install btrfs-progs mic2

Fedora 14

Add the MeeGo Tools repository for Fedora 14 to your /etc/yum.repos.d from here: http://repo.meego.com/MeeGo/tools/repos/fedora/14/meego-tools.repo

To that, you must also append the equivalent repository Fedora 13, otherwise you will not be able to install all packages due to missing dependencies. The file once merged should look something like this:

[meego-tools]
name=MeeGo Tools
type=rpm-md
baseurl=http://repo.meego.com/MeeGo/tools/repos/fedora/14
gpgcheck=1
enabled=1

[meego-tools-13]
name=MeeGo Tools 13
type=rpm-md
baseurl=http://repo.meego.com/MeeGo/tools/repos/fedora/13
gpgcheck=1
enabled=1

Once that is done, you can now install mic2: sudo yum install mic2

Ubuntu

Add MeeGo tools repository to your sources.list

for ubuntu 10.04

 deb http://repo.meego.com/MeeGo/tools/repos/ubuntu/10.04/ /

for ubuntu 10.10

 deb http://repo.meego.com/MeeGo/tools/repos/ubuntu/10.10/ /

Get and add the repository key (edit the path to match you ubuntu version).

 wget http://repo.meego.com/MeeGo/tools/repos/ubuntu/10.10/Release.key
 sudo apt-key add Release.key && rm Release.key

Update package lists

 sudo apt-get update

Install the packages

 sudo apt-get install mic2 btrfs-tools qemu-arm-static

Run MeeGo Image Creator

Create a working directory and copy your kickstart file there.

Latest kickstart files can be found gitorious (click appropriate branch and then tree).

NOTE: When using the kickstarts from the gitorious repository shown earlier you need to use also --release= option in mic to get @BUILD_ID@ set properly. If you wish to build current daily define --release=daily.

There are also kickstarts available with the weekly build repos which will generate that specific weekly release.

Image will be created in working directory by default.

Packages will be cached in mycachedir to speed up the next image creation.

If you are behind a proxy, you can set it to mic by adding

proxy=http://proxy.yourcompany.com:8080

to /etc/mic2/mic2.conf.

Loop image

sudo mic-image-creator --run-mode=0 --cache=mycachedir --format=loop --arch=armv7l --config=YOUR_KICKSTART 

Raw image (PREFERRED)

Create the image with following command:

sudo mic-image-creator --run-mode=0 --cache=mycachedir --format=raw --arch=armv7l --save-kernel --config=YOUR_KICKSTART

In the end of the mic-image-creator the output files are listed. In this list the file that contains raw in it name is the rootfs image and file with vmlinuz is the kernel. More information on writing the image/flashing the kernel see the pages for the appropriate device, e.g., N900 MMC installation

Troubleshooting

exit status 255 error

warning: %post(libgcc-4.4.2-12.2.armv5tel) scriptlet failed, exit status 255 

This is caused by SELinux, which can be disabled with:

setenforce 0

or

echo "0" > /selinux/enforce

This fix is valid, until you reboot your device.
