Finally, I've finished my EAGLE library for the AP7000.
It was quite a job, as the Atmel manuals did not contain good overviews over the BGA pinout, and because different names were used for the same signal in different places. (And, there was a few doc errors too). I had to dive deep into the 900+ page datasheet to sort it all out.
I've tried to cover the shortcomings of the AP7000 datasheet, by creating some sorted lists with BGAball/signalname crossreferences as well as a Ball layout picture with all signals and color coding on selected signals.
Feedback on this is much appreciated, especially if you find any errors in the documentation or library.
