Kernel:
get the latest one from friendlyarm
>wget  http://www.friendlyarm.net/dl.php?file=linux-2.6.32.2-mini2440_20110413.tgz
extract and use mini2440_defconfig or other matching config
>make ARCH=arm CROSS_COMPILE=arm-linux-gnueabi- mini2440_defconfig
make changes as neccesery on menuconfig
>make ARCH=arm CROSS_COMPILE=arm-linux-gnueabi- menuconfig
compile the kernel
>make ARCH=arm CROSS_COMPILE=arm-linux-gnueabi- -j8
to create uImage you should had uboot-mkimage
>apt-get install uboot-mkimage
>make ARCH=arm CROSS_COMPILE=arm-linux-gnueabi- uImage


Debootstrap:

get debootstrap
>sudo apt-get install debootstrap
get base debian filesystem on folder called rootfs, change this if you wish.
>sudo debootstrap --foreign --arch=armel squeeze rootfs/ http://ftp.debian.org/debian
create preinstall script as follow, you can make changes as necessery
>vi preinstall

#!/bin/bash
#
#script preinstall debian on arm
#after this run the arm system execute
#./debootstrap/debootstrap --second-stage
#i might also creted install.sh for simplified installation

Save and exit using ":wq" command.
Create install  script as follow, you can makes changes as neccesery
>vi install

#!/bin/bash
mount proc /proc -t proc
export PATH=$PATH:/bin:/sbin:/usr/bin:/usr/sbin:/usr/local/bin:/usr/local/sbin

./debootstrap/debootstrap --second-stage

rm -vrf /dev/.udev

passwd -d root

#rm install
#rm preinstall

cp -f /etc/apt/sources.list.bak /etc/apt/sources.list

rm linuxrc
ln -s /sbin/init /linuxrc

Save and exit using ":wq" command
changes both script into executable
>chmod a+x preinstall install
put them on the top of rootfs/ folder which you had debootstrap debian files.
Execute preintsall
>sudo ./preinstall 
Make modules kernel and install them to rootfs
>sudo make ARCH=arm CROSS_COMPILE=arm-linux-gnueabi- INSTALL_MOD_PATH=../rootfs modules_install

get the mkyaffs2-128M
>mkyaffs2-128M rootfs rootfs.yaffs2


uImage and rootfs
At this point you got uImage at kernel arch/arm/boot directory and debian squeeze preinstalled filesystem on rootfs.yaffs2 files You had to transfer the uImage via tftp to the board.

TFTP Server
>sudo apt-get install tftpd 
>sudo mkdir /srv/tftp -p
>sudo chmod 0777 /srv/tftp
>cp arch/arm/boot/uImage /srv/tftp/.

U-boot
get the working u-boot bin files from ftp://f0045951:friendlyarm@ftp.friendlyarm.net/src/u-boot-mini2440-20111108.zip
or compile yourself from sources

Connect the serial console, run terminal on 115200 baudrate speed no flow control, no hardware handshake. Get the board run on nor flash to start supervivi. If you had superboot, you should repalce it first to supervivi.
Also start the dnw or supervivi usb transfer tools.

press "q" on terminal
supervivi# load ram 0x31000000 [uboot-size] u

send the u-boot via dnw/supervivi transfer tools
supervivi# go 0x31000000
...
mini2440# nand scrub
mini2440# nand createbbt
Wait for it, don't desperate if terminal not response, it took about 20minutes

mini2440# nand write 0x31000000 u-boot
mini2440# dynpart
mini2440# dynenv set 40000

Put the switch/jumper to boot from nand and hit reset
Now transfer the uImage
mini2440# setenv serverip 10.42.43.1 
mini2440# setenv ipaddr 10.42.43.10 
mini2440# saveenv

See mtdparts for offset and sixe of kernel in nand flash
mini2440# nand erase 0x00060000 0x00500000 
mini2440# tftpboot 0x31000000 uImage
mini2440# nand write.e 0x31000000 kernel ${filesize} 
mini2440# setenv bootcmd nand read 0x31000000 kernel ${filesize}\;bootm 0x31000000
mini2440# setenv bootargs console=ttySAC0,115200 rootfstype=ext3 root=/dev/mmcblk0p2 init=/linuxrc 
mini2440# saveenv

Put the switch/jumper back to nor and hit reset
press "y" to get the yaffs2 file system, and send the rootfs.yaffs2 via dnw.

after finish put the switch back to nand and boot.
 you get noname console

run the install script on board
# ./install

hit the reset again. Now you got working debian squeeze filesystem onboard. use login root with no password.
