PreBuilt Images

If you dont want to compile OpenWrt you can find some prebuilt images here:

http://stud.netgroup.uniroma2.it/~saverio/sunxi/v3/

Prepare the microSD card

use fdisk to make two partitions the first one of 16Mb, and starting at sector 2048 (it should be the default value) the second partition can take all the rest of the SD card

format msdos the first partition: mkfs.msdos /dev/sdb1 format ext4 the second partition mkfs.ext4 /dev/sdb2

now you have to install the u-boot, the bootloader.

dd if=sunxi-spl.bin of=/dev/sdb bs=1024 seek=8
dd if=u-boot.bin of=/dev/sdb bs=1024 seek=32

now copy in th first partition the script.bin file and the kernel openwrt-sunxi-uImage and call the file exactly uImage

in the ext4 partition untar the tar.gz with the OpenWRT root filesystem

mount /dev/sdb1 /mnt/temp
cp openwrt-sunxi-uImage /mnt/temp/uImage
cp script.bin /mnt/temp/uImage
umount /mnt/temp

Prepare files in the ext4 partition

mount /dev/sdb2 /mnt/temp
cd /mnt/temp
tar -zxvf /home/saverio/Dropbox/Firmware/sunxi/v4/openwrt-sunxi-cubie-rootfs.tar.gz
cd ~
umount /mnt/temp

the system will not boot correctly (you will not see /proc) if you dont set init=/etc/preinit in your uboot evironment

you can adjust that with printenv (show all stuff) setenv (change the variable the contains init) saveenv

everything is documented in details here:
