    Debian Sid on the CuBox-i

I read
http://lifehacker.com/5974087/i-raised-my-kids-on-the-command-lineand-they-love-it,
and I was inspired. I order a CuBox-i2Ultra for my son and installed a custom
configured Debian Sid rootfs. I've provided the steps I took to get it working.
Setting up your environment

Packages you will probably need:

binutils-arm-linux-gnueabi
cpp-4.4-arm-linux-gnueabi
g++-4.4-arm-linux-gnueabi
gcc-4.4-arm-linux-gnueabi
gcc-4.4-arm-linux-gnueabi-base
gcc-4.4-base-armel-cross
libc-bin-armel-cross
libc-dev-bin-armel-cross
libc6-armel-cross
libc6-dev-armel-cross
libgcc1-armel-cross
libgomp1-armel-cross
libstdc++6-4.4-dev-armel-cross
libstdc++6-armel-cross
linux-libc-dev-armel-cross

Installing Packages

su -l # Become root

echo '# You can delete this file or comment out entries when done
deb http://ftp.us.debian.org/debian squeeze main contrib non-free
deb http://www.emdebian.org/debian squeeze main contrib non-free
' > /etc/apt/sources.list.d/emdebian.list

dpkg --add-architecture armhf
apt-get update
apt-get install g++-4.4-arm-linux-gnueabi

cd
mkdir CuBox-i
cd CuBox-i

Create uboot and kernel images

mkdir -p uboot
mkdir -p kernel/modules/
mkdir -p src
cd src
git clone https://github.com/rabeeh/u-boot-imx6.git
cd u-boot-imx6

Follow the instructions found here to build uboot images:
http://imx.solid-run.com/wiki/index.php?title=Building_the_kernel_and_u-boot_for_the_CuBox-i_and_the_HummingBoard
N.B., You might have to compile with platform specific config:
make <config> mx6\_cubox-i{1,2,2ultra,4pro}
cp SPL u-boot.img ../../uboot
cd ..
#git clone https://github.com/SolidRun/linux-imx6.git
#cd linux-imx6
git clone https://github.com/SolidRun/linux-linaro-stable-mx6.git
cd linux-linaro-stable-mx6

Follow the instructions found here to build kernel (i.e. 3.10 LTS):
http://imx.solid-run.com/wiki/index.php?title=Building_the_kernel_and_u-boot_for_the_CuBox-i_and_the_HummingBoard
N.B., you might want to modify the config to add netfilter & iptables spport,
as well as, TUN support. You can use:
ARCH=arm CROSS_COMPILE=/usr/bin/arm-linux-gnueabi- make menuconfig. Gentoo has some
good resources on what options to select.
N.B., I was unable to get iptables working, but I got TUN working by
setting: CONFIG_TUN=y in .config.
