As the CPU itself is the same on both cards (Mini2440 and Micro2440) they also should act the same. But there is always the risk of small details which are different... > Am 11.07.2012 14:13, schrieb Juergen Beisert: > > The A70 display support is part of the Mini2440 platform since the > > beginning in march 2009 (commit hash is > > 5102aa4acdbde305646ae60c5eec7042b5016a0e).

If the 3.4.4 does not work, even the older ones will not work. It seems the kernel code for the AT070TN83 is broken since the beginning. > The screen itself isn't the problem, by the way - I tried starting the > (chines) linux demo that came installed with the boards, and everything > worked fine. Then you should download their kernel[1] and try it instead of one from my BSP. If that will work for you and your display, we can take a look to the differences and find a solution for more recent kernel revisions.
