Hi guys, i got a oem box with s905x2 2g ddr4 100m ethernet and rtl8822cs wifi/bt module,its factory system was android9,and it was successful boot with g12a_s905x2_2g dtb but with some errors:
1.wifi is working,but BT is not reconigzed,there is only one sdio device in /sys/bus/sdio/devices/(sdio:0001)
2.there were some errors while booting coreelec like"/init:line67:can’t create /dev/kmsg:Opretion not permitted"
3.hdmi-cec not working.
4.its a little lagging while runing coreelec, and the frames while playing movies not very stable.
I have extracted factory dtb which i decompiled to dts.
