(AndrewDB) had started working on a port of Ubuntu for the platform. It appears he has been pretty busy, as there has been some progress in the meantime…
AndrewDB managed to run Ubuntu on UG802 HDMI Stick. Wifi is starting to work, although there are still some minor issues to resolve. He plans to have a dual-boot Android/Linux ROM available in several weeks for RK3066 based devices such as the UG802 and MK808. Eventually, AndrewDB also intends to release a dual boot ROM Android Jelly Bean + Ubuntu for RK3066 tablets.
That’s all the information I have for now. This is still work in progress (See TODO List) and no binary has been released yet.
