Correct. Edit uEnv.ini to use the "meson-sm1-x96-air-gbit.dtb" as it's probably a close match. SM1 boxes have some known issues with hardware decoding so if you hit lockups you'll need to disable it (DRMPRIME on, Hardware Decode off).
Just got the box and after few hours i read your post again and now i have it working but wifi is not working at all? Should i try another dtb file?
Wifi is working correctly on CE image.
Is there a way to check wifi chipset without opening the box?
