ARM/Creating ARM image using MeeGo Image Creator

Revision as of 10:21, 21 July 2010

Under construction

Requirements

 * Fedora 12 or Fedora 13
 * mkfs.ubifs, ubinize and meego-arm-static from meego-tools repositories (install instructions below).
 * MeeGo Image Creator from git
     * requires git-core (# yum install git-core)

Install qemu-arm-static, mkfs.ubifs and ubinize

NOTE: Fedora has its own mtd-utils package, but that does not include the required tools for ubi creation.

NOTE: You need both of the repositories below for Fedora 12/13, because some packages are only available in Fedora 11 currently.

Add following lines to for example /etc/yum.repos.d/meego-tools.repo

[meego-tools-f12]
name=Meego tools F12
failovermethod=priority
baseurl=http://repo.meego.com/tools/repos/fedora/12/
enabled=1
gpgcheck=0

[meego-tools-f11]
name=Meego tools F11
failovermethod=priority
baseurl=http://repo.meego.com/tools/repos/fedora/11/
enabled=1
gpgcheck=0

Install the required package:

sudo yum install mtd-utils mtd-utils-ubi qemu-arm-static

Get and install MeeGo Image Creator code

If Git version control system or make are missing those can be installed with commands:

sudo yum install git

Git clone the Meego Image Creator sources to temporary directory and install the codes:

git clone git://gitorious.org/meego-developer-tools/image-creator.git
cd image-creator
sudo tools/mic-check-alldeps
make clean
make
sudo make install
cd ..

Run MeeGo Image Creator

Create a working directory and copy your kickstart file there. Sample kickstart files can be found here. In the working directory run either of the following commands as root:

Image will be created in working directory.

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.

Ubifs image (OBSOLETE)

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

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 

You will get a directory which ends with -raw suffix and file that includes vmlinuz in its name. The directory contains the *.raw file that is put to the memory card and vmlinuz is put to the N900 with flasher. For information on writing the image/flashing the kernel see: Installation methods

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:

echo "0" > /selinux/enforce

This fix is valid until you reboot your device.
