Bootstrap a minimal debian for olinuxino-a20-lime2

Thanks to lukas2511 for quick bootstrap.

Build minimal U-boot

sudo docker pull debian:stable
git clone https://github.com/bleuchtang/olinuxino-a20-lime2
cd olinuxino-a20-lime2 && sudo docker build -t debian/olinux .

Build minimal arm debootstrap

We cannot perform a debootstrap in dockerfile bacause dockerfile doesn't accept privileged mode. For more details see docker issue

sudo docker run --privileged -i -t -v $(pwd)/olinux/:/olinux/ debian/olinux sh ./olinux/create_arm_debootstrap.sh

You shoud have both debootstrap and sunxi directories in olinux/

Install on a sdcard

Partitioning

mmc=/dev/sdc
parted -s ${mmc} mklabel msdos
parted -a optimal ${mmc} mkpart primary fat32 1 16MiB
parted -a optimal ${mmc} mkpart primary fat32 16MiB 100%
mkfs.fat -F 32 ${mmc}1
mkfs.ext4 ${mmc}2

Installation

dd if=olinux/sunxi/u-boot-sunxi/u-boot-sunxi-with-spl.bin of=${mmc} bs=1024 seek=8
mount ${mmc}1 /media/usb/
cp olinux/sunxi/script.bin /media/usb/
cp olinux/sunxi/linux-sunxi/arch/arm/boot/uImage /media/usb/
umount /media/usb
mount ${mmc}2 /media/usb/
cp -r olinux/debootstrap/* /media/usb/

You probably want to Build your own docker image

Because it's quick and easy; tutorial here
Because you shoudn't trust regitry images; demonstration here
