The very first result that Google gave me when trying to find information on running XBMC on the CubieBoard (which is powered by the Allwinner A10), was this link.

This, in clear letters states…
“Avoid hardware that uses the Allwinner series of chips (such as the Allwinner A10). Development is not going well for these devices.”
Yes, “Avoid” really is written in bold. This does not bode well.
I shall try, none-the-less. After all, I have my backup img files for when things go horribly wrong.
