Hi Ivan, Last week I went through call of duty to create working LiveSuit image for my Cubietruck. I asked about some things that are not clear to me here: https://groups.google.com/d/msg/linux-sunxi/N301MZXe6AM/zLUgZgwkCQAJ and here: http://www.cubieforums.com/index.php/topic,3887.msg24181.html#msg24181 but not much interest in this topic. > > Actually the biggest problem is that none of this is documented and these > programs usually do not give you any version or help.

I extracted some parts from dl.cubieboard.org image but this cause: update mbr: partcount = 4 update mbr file ok fsbuild error.

Can offer testing on Cubietruck and writing some articles.
