下載與解壓縮toolschain：

http://www.friendlyarm.net/dl.php?file=arm-linux-gcc-4.4.3.tgz
$ sudo tar xvf ~/arm-linux-gcc-4.4.3.tgz -C /

下載u-boot：

$ mkdir mini2440
$ cd mini2440/
$ git clone git://repo.or.cz/u-boot-openmoko/mini2440.git
$ mv mini2440/ u-boot/
$ cd u-boot/

編譯u-boot：

$ export PATH=/opt/FriendlyARM/toolschain/4.4.3/bin:$PATH
$ export CROSS_COMPILE=arm-none-linux-gnueabi-
$ export ARCH=arm
$ make mini2440_config
$ make all

將NOR開關扳到on，再將開發版電源打開，準備燒入u-boot：

Enter your selection: q                                                         
Supervivi> load flash 0 243360 u                                                
USB host is connected. Waiting a download. 

關掉開發版電源，將NOR開關扳到off，再將開發版電源打開，然後在console輸入下面指令：

MINI2440 # nand scrub
MINI2440 # nand createbbt
MINI2440 # dynenv set 40000
MINI2440 # saveenv
MINI2440 # reset

下載與解壓縮kernel：

http://www.friendlyarm.net/dl.php?file=linux-2.6.32.2-mini2440_20110413.tgz
$ cd ../
$ mkdir kernel
$ cd kernel/
$ tar xvf ~/linux-2.6.32.2-mini2440_20110413.tgz -C ~/mini2440/kernel/
$ cd linux-2.6.32.2/

編譯kernel：

$ cp config_mini2440_vga1024x768 .config
$ make menuconfig
$ make

產生uImage：

$ cd ../../
$ ./u-boot/tools/mkimage -A arm -O linux -T kernel -C none -a 0x30008000 -e \
0x30008000 -d ./kernel/linux-2.6.32.2/arch/arm/boot/zImage ~/tftpboot/uImage

燒入kernel：

MINI2440 # mtdparts
MINI2440 # nand erase 0x60000 0x300000
MINI2440 # tftp 0x32000000 uImage
MINI2440 # nand write 0x32000000 0x60000 0x300000

建立rootfs：

$ cd ../myfs/
$ mkdir rootfs
$ cd rootfs
$ mkdir bin dev etc lib proc sbin sys usr mnt tmp var
$ mkdir usr/bin usr/lib usr/sbin lib/modules
$ cd dev
$ sudo mknod -m 666 console c 5 1
$ sudo mknod -m 666 null c 1 3
$ cd ../etc
$ vim fstab
proc            /proc   proc    defaults    0   0
sysfs           /sys    sysfs   defaults    0   0

$ chmod 755 fstab
$ mkdir init.d
$ vim init.d/rcS
#! /bin/sh

/bin/mount -a
/bin/mount -t tmpfs mdev /dev
/bin/echo /sbin/mdev > /proc/sys/kernel/hotplug
mdev -s

$ chmod 755 init.d/rcS
$ vim inittab
::sysinit:/etc/init.d/rcS
::respawn:-/bin/sh
::ctrlaltdel:/bin/umount -a -r

$ chmod 755 inittab
$ vim profile
# /etc/profile: system-wide .profile file for the Bourne shells

echo
echo -n "Processing /etc/profile... "
# no-op
echo "Done"
echo

$ chmod 755 profile

編譯與安裝busybox：

$ cd ~/
$ wget http://busybox.net/downloads/busybox-1.21.1.tar.bz2
$ tar -xvjpf ~/busybox-1.21.1.tar.bz2
$ cd busybox-1.21.1
$ make menuconfig
$ make
$ make install CONFIG_PREFIX=/home/renee/myfs/rootfs

編譯與安裝kernel模組：

$ cd ../mini2440/kernel/linux-2.6.32.2/
$ make modules
$ make modules_install INSTALL_MOD_PATH=/home/renee/myfs/rootfs

下載yaffs2生成工具與製作：

http://www.friendlyarm.net/dl.php?file=linux_mktools.zip
$ sudo apt-get install zip
$ unzip linux_mktools.zip
$ mkyaffs2image /home/renee/myfs/rootfs rootfs.yaffs2

燒入rootfs.yaffs2：

MINI2440 # tftp 0x30008000 rootfs.yaffs2
MINI2440 # nand erase 0x560000 0x265b900
MINI2440 # nand write.yaffs 0x30008000 0x560000 0x265b900

設定u-boot開機參數，如果你要使用nfs開機，設定如下：

MINI2440 # setenv bootargs console=ttySAC0,115200 noinitrd init=/sbin/init mini2440=1tb 
ip=192.168.200.150:192.168.200.22:192.168.200.1:255.255.255.0 root=/dev/nfs rw 
nfsroot=192.168.200.22:/home/renee/myfs/rootfs
MINI2440 # setenv bootcmd 'nboot.e kernel; bootm'
MINI2440 # saveenv
MINI2440 # boot

如果你要使用yaffs2開機，設定如下：

MINI2440 # setenv bootargs console=ttySAC0,115200 noinitrd root=/dev/mtdblock3 rootfstyle=yaffs2 
init=/sbin/init mini2440=1tb
MINI2440 # setenv bootcmd 'nboot.e kernel; bootm'
MINI2440 # saveenv
MINI2440 # boot
