android needs specific kernel patches.
we have a working android kernel for SMP864x and SMP865x... it also works for SMP863x but it does not have the drivers for the SMP863x components like IDE.
it should be possible to port the drivers to this much newer kernel version, but I have no idea how much needs to be adjusted.
second problem is the audio/video driver. The sigma-android implementation uses DCCHD, which is a directFB implementation.
DCCHD is also available for SMP863x so it might work, but there could be android specific modifications in the android DCCHD... nobody tested that yet.
