This page describe how to customize a ubuntu image for radxa rock.

Install required packages

   sudo apt-get install qemu-user-static binfmt-support

Generate the image

   dd if=/dev/zero of=rock_rootfs.img bs=1M count=1024
   mkfs.ext4 -F rock_rootfs.img
   sudo mount -o loop rock_rootfs.img /mnt

The fast way is to make a ubuntu image is downloading a recent pre-built ubuntu rootfs from linaro

   wget https://releases.linaro.org/13.08/ubuntu/raring-images/alip/linaro-raring-alip-20130826-474.tar.gz
   sudo tar zxvf linaro-raring-alip-20130826-474.tar.gz -C /mnt
   cd /mnt
   sudo mv binary/* .
   sudo rmdir binary

Prepare chroot

   sudo cp /usr/bin/qemu-arm-static /mnt/usr/bin
   sudo modprobe binfmt_misc
   sudo mount -t devpts devpts /mnt/dev/pts
   sudo mount -t proc proc /mnt/proc

Chroot and post configuartion

   sudo chroot /mnt

Now we are in the target rootfs. To be continued...
