A very thank you to TonyMac32 and the great Armbian comunity!
I've compiled the desktop image with no special options (just select the target) and everything is running very nice.
The CPU clock is set to max 1.5 GHz, slightly overclocked but it runs without headsink around 50-60 °C on high loads the temperatur rise up to around 65-68 °C in my case.
OpenGL (glxgears) and Gles2 (es2gears) runs fine, even the WebGL in Chromium is supported.
Video is not HW accelerated in included mpv and Chromium, I think there are any patches needed, but its ok at the moment.
I have only one problem, there is no audio. Only the DummyOutput is present. aplay -l says no soundcards found...
dmesg has no message related to "sound" or "audio". USB soundcard works pretty well but is not that great experiene
Can someone give me a hint to get sound working? load missing modules etc.?
For easy testing, the image i compiled can be downloaded here (7zip file): https://drive.google.com/open?id=1Xl-4_R1aolxJMZFqlZdb0voNxOxbJ4PC
