Guys, I'm considering removing A20 support from master branch, which would also mean no more nightly images and certainly no stable images once LE10 is released. I tested olinuxino micro A20 board today and there is a ton of kernel related issues. In order to fix them I would need to spend considerable amount of time studying various HW cores which I don't want (A20 HW is pretty different in comparison to any other currently supported AW SoC).
Observerd issues:
- HDMI audio driver crashes at resolution switch
- HDMI audio sometimes doesn't work
- HDMI EDID is sometimes read incorrectly (fall back to 1024x768 and no audio)
- HW video decoding crashes (out of memory) during interlaced H264 video playback
- after playback, Kodi GUI may become corrupted (GPU driver issue? Kodi bug? who knows)
In my opinion, above issues make images unusable, except in some not so common cases. Additionally, SoC is very weak and memory has limited bandwith. Even a bit newer H3 is much better supported and has none of the described problems.
If there is someone who wants to fix above and possibly other issues, I will be glad to keep A20 port alive or resurrect it later.
