Re: Running android on Dom U. on ARM Cubieboard2.

Hi Dario,

Exactly, I am working on SAMSUNG-alike dual android system.

Yeah, thanks for sharing the information. I had not given thoughts
about these problems and was thinking of Android on Dom0 as well as
DomU.

It will be really helpful if Srinivas and Ian can throw some lights on
the questions raised..

Thanks
