Did you saw this?
http://download.csdn.net/download/fgwntg/4401182
I have no csdn points, though cannot download it to see what's inside, but words in comments are "Full, Complete" etc (at least google translates it so)
Anyone knows how to download from csdn? It apears to be a kind of chinese developers network (similar to msdn, rsdn, etc..)
is it different than https://github.com/OLIMEX/OLINUXINO/blob/master/HARDWARE/A13-PDFs/A13%20data%20sheet%20.pdf ?
I don't know. I hope it is.
Though it may appear to be completely chinese.
They are the same!
