First create a SD card. Please get some instruction from below site:

NOTE: After formatting SD card, you must pull out SD card and insert it into the computer, then unpack and install rootfs, otherwise it may appear the phenomenon which can not mount EXT3 partition. It's better that the capacity of SD Card bigger than 2G.

Short Version:

255 Heads 63 Sectors nn cylinders
cylinders = Byte/255/63/512 
Round down the cylinders
Create 1 FAT32 Partition (LABEL1)
Create 1 Linux Partition (LABEL2)
Create FAT File System
mkfs.msdos -F 32 /dev/sdx1 -n LABEL1
/dev/sdx1 has to be your SD Card
Create EXt3 File System
mkfs.ext3 -L LABEL2 /dev/sdix2
/dev/sdx2 has to be your SD Card

Kernel and RootFS

After you created the SD-Card go to the directory of the devkit8000 Distribution on the CD\devkit8000\linux\image.

Copy MLO,uboot.bin and uImage from CD to /media/LABEL1  (FAT32 Partition)

Get a Ubuntu rootfs from here:

Unpack and install rootfs

7za x ubuntu-9.10-minimal-armel.tar.7z
tar xvf ubuntu-9.10-minimal-armel-1.1.tar
cd ubuntu-9.10-minimal-armel-1.1
tar xvf armel-rootfs-200912081224.tgz -C /media/LABEL2/ (EXT3 Partition)

System configuartion

Edit /etc/network/interfaces add:

auto eth0
iface eth0 inet dhcp

or edit /media/2/etc/network/interfaces add:

auto eth0
iface eth0 inet static

To get a IP on startup.

Edit /etc/rc.local add:


This sets the clock while booting.

Edit /media/2/etc/resolv.conf add:


This sets the DNS,determined based on your area

System Deveplopment Environment

Put the SD Card、7inch LCD、Serial Line 、5V power supply and net Cable in the DEVKIT8000.

u-boot env

Power on DEVKIT8000 and boot,press Spacebar while bootdelay.

On the DEVKIT8000 u-boot commandline edit the Bootcmd and Bootargs Env Var.

setenv bootcmd 'mmcinit;fatload mmc 0 80300000 uImage;bootm 80300000'
setenv bootargs 'console=ttyS2,115200n8 root=/dev/mmcblk0p2 rw rootwait video=omapfb:mode:7inch_LCD'
