Pre-requisites

• Debian GNU Linux 7 Wheezy
• Arch i386 is suggested

I suggest to create a dev environment using an LXC container with Debian Wheezy i386. You can find an appropiate template here: https://github.com/daniviga/ix2-200/blob/master/lxc-template/lxc-debian-i386

The config file provided is higly customized and stripped down. Please revise your configuration using make menuconfig before compile the kernel (see below).

Cross compiling the kernel

Setup cross compiler

dpkg --add-architecture armel
apt-get update

apt-get install build-essential fakeroot kernel-package linux-source u-boot-tools zlib1g-dev libncurses5-dev binutils-multiarch

Into your /etc/apt/sources.list add:

echo "deb http://emdebian.org/~thibg/repo/ sid main" >> /etc/apt/sources.list
apt-get update

apt-get install gcc-4.7-arm-linux-gnueabi binutils-arm-linux-gnueabi

update-alternatives --install /usr/bin/arm-linux-gnueabi-gcc arm-linux-gnueabi-gcc /usr/bin/arm-linux-gnueabi-gcc-4.7 46 \
      --slave /usr/bin/arm-linux-gnueabi-gcov arm-linux-gnueabi-gcov /usr/bin/arm-linux-gnueabi-gcov-4.7

Patch the sources

cd /usr/src/
tar xjvf linux-source-3.2.tar.bz2
wget https://raw.github.com/daniviga/ix2-200/master/configs/config-3.2.46-ix2_200-2
wget https://raw.github.com/daniviga/ix2-200/master/0001-Modified-rd88f6281-setup-file-to-support-ix2-200.patch

cd linux-source-3.2
patch -p1 < 0001-Modified-rd88f6281-setup-file-to-support-ix2-200.patch

Configure the kernel

export CC=arm-linux-gnueabi-gcc
export CROSS_COMPILE=arm-linux-gnueabi-
export ARCH=arm
export DEB_HOST_ARCH=armel

make-kpkg clean

cp ../config-3.2.46-ix2_200 .config
make oldconfig
make menuconfig

Build the kernel

fakeroot make-kpkg -j2 --arch arm --cross-compile arm-linux-gnueabi- --append-to-version=-ix2-200 --initrd kernel_image kernel_headers

Install the new kernel on the device

mkimage -A arm -O linux -T ramdisk -C gzip -a 0x00000000 -e 0x00000000 -n initramfs -d initrd.img-3.2.46 uInitrd-ix200
mkimage -A arm -O linux -T kernel  -C none -a 0x00008000 -e 0x00008000 -n Linux-3.2.46 -d vmlinuz-3.2.46 uImage-ix200

flash_eraseall /dev/mtd0
flash_eraseall /dev/mtd1

nandwrite -p /dev/mtd0 /boot/uImage-ix200 
nandwrite -p /dev/mtd1 /boot/uInitrd-ix200 

Boot examples

Boot from USB

usb start

setenv bootargs $(bootargs_console)
ext2load usb 0:1 0x00800000 /uImage-new
ext2load usb 0:1 0x01100000 /uInitrd-new
bootm 0x00800000 0x01100000

Boot from internal flash

setenv mtdparts 'mtdparts=orion_nand:0x100000@0x000000(uboot)ro,0x20000@0xA0000(uboot_env),0x300000@0x100000(uImage),0x1000000@0x540000(uInitrd)'
setenv bootargs_console 'console=ttyS0,115200 mtdparts=orion_nand:0x300000@0x100000(uImage),0x1000000@0x540000(uInitrd) root=/dev/mapper/sata-root'
setenv bootcmd 'setenv bootargs $(bootargs_console); nand read 0x800000 uImage; nand read 0x1100000 uInitrd; bootm 0x00800000 0x01100000'
saveenv
