Linux / Hardware : Using a Cubieboard as (web)server

I was searching how to replace my X86 server by some arm based server.  The main objectives was to lesser power comsumption and optimize the fault tolerance of m infrastructure (several am computer is better than one simple x86 machine running virtual machines…).

After a little research on arm computer, I chose the Cubieboard for its good power/price ratio and the support we can find for it.

Basicaly, I found all informations I needed on the following site :

SDCard preparation

The hardware

SanDisk_10xI used a SanDisk microSDHC “ultra 10x” as main drive to insure good speed (the cubieboard’s internal nand flash seems a little bit slow compared to this microSD).


Thanks to sdcard optimization (see article), I got the following results:

  • big files  before optimization : 821 Mb/s, after : 980 Mb/s
  • small files : Before optimizations : 270 Mb/s, after 618 Mb/s


I organized the sdcard as follow :

  • a first partition for /boot of 28 Mb: from block 8192 to 65535 (fat fs, as the cubiboard only support fat for booting)
  • a second part for / starting at block 65536 to the end (ext4 fs)

Deploying the base system

The way I chose to Install Debian on my cubieboard, I chose to get an image of a base install and then copy files to the final destination SdCard (by default, the cubieboard tries to boot from SDcard slot first).

I got the base debian wheezy image from :

Then I wrote this image on a usb stick (need to be >=1Gb):

dd if=debian_wheezy_armhf_v1_mele.img of=/dev/sdc bs=1024


Finaly I used rsync to copy the content of the 2 partitions form the usb stick to the 2 partitions of my SdCard (first part = boot, second part = root)

rsync -avc /source /target

 Make the SdCard bootable

To allow the Cubieboard to boot on a microSD, we need to copy the u-boot bootloader on the very first blocks. In order to do that we have to compile u-boot for this specific board (I’m using archlinux on my laptop and /dev/sdc is the microSd) :

yaourt -S arm-none-linux-gnueabi
git clone git://
cd u-boot-sunxi
make 'cubieboard' CROSS_COMPILE=arm-none-eabi-
dd if=spl/sunxi-spl.bin of=/dev/sdc bs=1024 seek=8
dd if=u-boot.bin of=/dev/sdc bs=1024 seek=32


Then put the card in the cubieboard, And was able to ssh to it after a little research for the ip it had been given by my DHCP (l/p = root/root)

Finalize the system

Basic Customization

echo "<MY_HOSTNAME>" > /etc/hostname



I updated the whole sytem thought apt-get dist-upgrade, then like for my Sheevaplug I made some tmpfs mountpoint in /etc/fstab

I also set the IO Scheduler to Deadline (better than “noop” for nand) and overclocked a little bit the SoC in rc.local:

deadline scheduler
cpufreq-set -u 1.2GHz


Make use of the SATA Port

As I want to use my Cubieboard as a personnal web server with lots of images and/or videos, I needed to use an hardrive in addition to the SdCard.

The Cubieboard provide a Sata Port and suitable cable for a 2.5 inch drive, but the port is not powered by default. To enable this, you have to modify the boot params of the bootloader (the .fex file in /boot):

apt-get install g++
git clone git://
cd sunxi-tools
mount /boot
./bin2fex /boot/script.bin /tmp/script.fex
nano /tmp/script.fex # set sata_power_en = port:PB08<1><default><default><0>
./fex2bin /tmp/script.fex /boot/script.bin
umount /boot
echo "sw_ahci_platform" >> /etc/modules # load sata module at boot


Note that depending on the power your hardrive need, you may have to plug another power supply throught the mini-usb (OTA). In my Case, I had to add an 1A powersupply together with the original one…

After a reboot the hardrive powers on and is recognized by the system.
Installating the Lamp stack is then pretty straight forward, like on any debian server…
