We may want to install lubuntu desktop/​server to SD card, here is a guide for you. This guide is for Linux platform only. We take Desktop as a example in this guide. If you are interested in Server, just replace the images with server one.

• Any Linux environment,​ we want fdisk, dd, tar, wget commands
• An SD Card(at least 2GB)

We assume card=/dev/sdd here

$card=/dev/sdd
$sudo dd if=/dev/zero of=${card} bs=1024 seek=544 count=128

$sudo dd if=u-boot-sunxi-with-spl-ct-20131102.bin of=$card bs=1024 seek=8

$ sudo fdisk /dev/sdd

Using the fdisk command to create 2 partitions on the SD Card, e.g.

• 1st partitions start from 2048 sectors, 64MB in size
• 2nd partitions just keep it all default

Show bellow

 Device Boot      Start         End      Blocks   Id  System
/dev/sdd1            2048      133119       65536   83  Linux
/dev/sdd2          133120    15278079     7572480   83  Linux

Also we recommend you to look at Bootable_SD_card

$sudo mkfs.ext2 ${card}1
$sudo mkfs.ext4 ${card}2
	 

$mkdir /tmp/sdd1 /tmp/sdd2
$sudo mount -t ext2 ${card}1 /tmp/sdd1
$sudo mount -t ext4 ${card}2 /tmp/sdd2
$sudo tar -C /tmp/sdd1 -xvf bootfs-part1.tar.gz
$sudo tar -C /tmp/sdd2 -xvf rootfs-part2.tar.gz
$sync
$sudo umount /tmp/sdd1
$sudo umount /tmp/sdd2

• Mount rootfs partitions

After login to lubuntu system on Cubietruck with linaro,

$sudo su - root   --> change to root user
#mkdir /tmp/1 /tmp/target
#mount /dev/mmcblk0p2 /tmp/1
#mkfs.ext4 /dev/sda1
#mount /dev/sda1 /tmp/target

• Moving rootfs

#(cd /tmp/1; tar --backup -c *) |tar -C /tmp/target -xv

• Changing Kernel Parameters

#mount /dev/mmcblk0p1 /mnt/
#vi /mnt/uEnv.txt
(Change root=/dev/sda1)

So the file's content would like bellow

cat /mnt/uEnv.txt
root=/dev/sda1
extraargs=console=tty0 hdmi.audio=EDID:0 disp.screen0_output_mode=EDID:1280x720p50 rootwait panic=10 rootfstype=ext4 rootflags=discard

• Sync to disk, and reboot to your hard drive

#sync
#umount /mnt
#reboot

After installing rootfs to SSD, we will get much more better experience。

If we want to change to VGA output default, we need to modify the script.bin at the 1st partition

$bin2fex script.bin 1.fex
$vim 1.fex (and change screen0_output_type to 4)
$fex2bin 1.fex script.bin

Cubietruck have AP6210 wifi/bt module combo on board, to load the module,

#modprobe bcmdhd
