I've read the link at, and know that this board is problematic. I'm an owner
of a A13-OLinuXino.

You have to wait until free drivers come stable.
I tried to install the free driver, but it depends on a nonfree shader
compiler. A free shader compiler has to be written.
The variant without WiFi does not have internal memory.
It can be used in freedom, if you do not use any graphics at all. If you do
not use the internal memory, you can use the IO pins with external hardware.
If you use it as an Ogg Vorbis player, you do not need any nonfree software.
It also run a Web-Server, once Linux-Libre is ported, and WiFi from
ThinkPenguin us used.
I've found out that the board's design is "Open Source", but not Free as in
Freedom, as they use the nonfree CadSoft EAGLE. Does anybody know a free
replacement program that is easy to use and as powerful as EAGLE.
The GNUblin does not have a GPU nor a VPU, they use EAGLE too.
