Building LiveSuit image

[Piotr Król]

Hello,
couple of days ago I tried to create LiveSuit image for Cubietruck. I
tried sunxi-bsp (https://github.com/linux-sunxi/sunxi-bsp) and
allwinner-pack-tools (https://github.com/matson-hall/allwinner-pack-tools.git).
Unfortunately no success. First use allwinner-tools repo without A20 files (eFex, eGON, wboot) and
second after long fight created image that doesn't boot.

I tried imgRePacker by RedScorpio
(http://forum.xda-developers.com/showpost.php?p=28329544&postcount=1)
which works great for my needs.

Extracted image present pretty complicated layout (this is based on cubieboard.org image):

==========================[ STOP ]==========================

I tried to combine above files with sunxi-bsp but without success.

Some files are self-explanatory (bootlaoder, rootfs, boot0, boot1). But maybe
someone can explain role of /work/cb-linux-sdk/build/ct-debian/pack ? Are those
files required for booting ?

Is there any documentation describing LiveSuit image layout and method of
creating it for A20 ?

Is there anyone who managed to create LiveSuit image for A20 platform using
open source tools ?
