= Build the Android sources =
Just go to the source directory and make:
{{{
$ cd /usr/src/android/mydroid
$ . build/envsetup.sh 
$ lunch a5it-userdebug
$ make -j4
}}}

The build process should go until it shows:
{{{
Install system fs image: out/target/product/gen7/system.img
Installed file list: out/target/product/gen7/installed-files.txt
}}}

= Create your image =
The Android 2.2 port for A5IT use the OpenAOS multiroot facility. The Android image will system in an ext3 image

== Create and mount an ext3 image ==
{{{
$ dd if=/dev/zero of=/usr/src/android/rootfsfroyo.img bs=1M count=128
$ mke2fs -j /usr/src/android/rootfsfroyo.img
$ mkdir /usr/src/android/rootfs
$ sudo mount -o loop /usr/src/android/rootfsfroyo.img /usr/src/android/rootfs
}}}

== Copy the build output to your image ==
{{{
$ cd /usr/src/android/mydroid/out/target/product/gen7/root
$ tar cf - . | ( cd /usr/src/android/rootfs ; tar xfBp -)
$ cd ../system
$ tar cf - . | ( cd /usr/src/android/rootfs/system ; tar xfBp -)
}}}

== Add the SGX libraries ==
 
To do this you need to get and install the omap android sdk as mentioned [http://code.google.com/p/rowboat/wiki/ConfigureAndBuild#Install_the_Android_Graphics_SGX_SDK_on_Host_Machine here].
{{{
$ cd [OMAP_ANDROID_SDK_DIRECTORY]/gfx_rel_es3.x_android
$ DISCIMAGE=/usr/src/android/rootfs ./install.sh
}}}

You only need to do this once for each image you create. Once you've done it once you can copy new builds into the same image file.

== Change the ownership of the image files and unmount the image ==
{{{
$ sudo chown -R root:root /usr/src/android/rootfs/.
$ sudo umount /usr/src/android/rootfs 
}}}

== Put the system image on your device ==
First, you should reboot your device using recovery mode, then choose from the '''Developer Edition Menu''' the option '''Acess HDD using a PC''' and connect your device on a USB port of your computer.

Once the disk of the Archos is mounted on your system, copy the image to it
{{{
$ cp /usr/src/android/rootfsfroyo.img /media/ARCHOS
}}}

== Set up menu.lst ==
The menu.lst file at the root of the archos disk should contain teh following line to boot your image
{{{
Android|/dev/sda1|rootfsfroyo.img|/init
}}}
Once it is set, you can umount the Archos and reboot you !
