Hello, it's my first time posting here. I have 2 Beelink MX III S905 devices with 2/16. I'm using mainly kszaq's LibreElec on them with his gxbb_p200_2G_1Gbit.dtb with great success so far.
My elder parents still use an old core2quad desktop pc, my plan is to swap one of my boxes with it, around december.
Last week i tried your "Armbian_5.27_S905_Ubuntu_xenial_4.12.0-next-20170516+_mate.img.xz" image, in first round with the included dtb-s. I booted it up from android update/backup menu with an USB3 flash drive. Some dtb worked, some not, if you're interested i can talk more about it.
The most successul boot was with your "meson-gxbb-p200-lan.dtb" file. Wireless works about half times, wired ethernet works all the times, but it's settings are uneditable by gui. The box boots up in low resolution, in this resolution the second test files play nicely in windowed mode, in fullscreen it does not. After setting 1080p via gui, the test video does not start anymore.
After Installing VLC from Synaptic package manager, i managed to play both files in windowed. I uploaded to the box some h264 coded 1080p 60fps videos, those played surprisingly well too in windowed. Fullscreen does not work so far, instant freezes, but the time counter continues. I monitored it in htop, i've seen full load on all cores, probably the resizing algorithm is at fault.
Browsing works, i tried out chromium, with adblocker it is better than expected. Most videos play, fullscreen freezes videos.
I noticed there is no sound and bluetooth so far, also the highest resolution available is 1080p from MATE gui.
Now this is so far
Thank you for your work so far. Let me know if i can help by testing, providing logs, and others. I have no uart acces so far, but i can operate via ssh if there is no screen.
Cheers,
