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=rootfs.ext4 bs=1M count=1024
   mkfs.ext4 -F -L linuxroot rootfs.ext4 #kernel use the label linuxroot to mount the rootfs as /
   sudo mount -o loop rootfs.ext4 /mnt

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

   wget http://releases.linaro.org/14.10/ubuntu/trusty-images/alip/linaro-trusty-alip-20141024-684.tar.gz
   sudo tar zxvf linaro-*.tar.gz -C /mnt
   cd /mnt
   sudo mv binary/* .
   sudo rmdir binary

Copy the kernel modules you built from Building the kernel

   sudo mkdir -p /mnt/lib/modules
   sudo cp -r /path/to/linux-rockchip/modules/lib/modules/3.0.36+ /mnt/lib/modules

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 configuration

   sudo chroot /mnt

Now we are in the target rootfs, let's continue to configure the system.

Change the default shell to bash.

   root@target:# rm /bin/sh && ln -s /bin/bash /bin/sh

Install the pre-installed packages

   root@target:# apt-get update
   root@target:# apt-get install ssh vim usbutils wpasupplicant wireless-tools

Add a script to link the mtd blocks to names

   root@target:# vim /usr/local/bin/mtd-by-name.sh

Add the following

   #!/bin/sh -e
   # mtd-by-name link the mtdblock to name
   # radxa.com, thanks to naobsd
   rm -rf /dev/block/mtd/by-name/
   mkdir -p /dev/block/mtd/by-name
   for i in `ls -d /sys/class/mtd/mtd*[0-9]`; do
       name=`cat $i/name`
       tmp="`echo $i | sed -e 's/mtd/mtdblock/g'`"
       dev="`echo $tmp |sed -e 's/\/sys\/class\/mtdblock/\/dev/g'`"
       ln -s $dev /dev/block/mtd/by-name/$name
   done

Add the mtd-by-name script to rc.local to get executed every time system boots

   root@target:# vim /etc/rc.local

Add this line before exit 0

   /usr/local/bin/mtd-by-name.sh

Now we are done! :D

   root@target:# exit
   sync
   sudo umount /mnt

Now you have rootfs.ext4 as the rootfs image for RR.


Trouble shooting

bluez package configure error

Setting up bluez (4.101-0ubuntu8b1) ...
reload: Unknown instance: 
invoke-rc.d: initscript dbus, action "force-reload" failed.
start: Job failed to start
invoke-rc.d: initscript bluetooth, action "start" failed.
dpkg: error processing bluez (--configure):
subprocess installed post-installation script returned error exit status 1
dpkg: dependency problems prevent configuration of blueman:
blueman depends on bluez (>= 4.25); however:
Package bluez is not configured yet.
...

It turns out the bluez package needs the dbus service running in order to configure properly. The following works:

   service dbus start
   dbus start/running, process 24551
   dpkg --configure bluez

Non root user can not use the network

Edit /etc/group and add

   inet:x:3003:root
   net_raw:x:3004:root

and then run

   gpasswd -a username inet

Alternative way

you can prepare your own ubuntu rootfs on Radxa Rock
