I have MXV+ device 1G, 1 Gbit (MXV+ (MXV Plus) Review: Android TV Box powered by 64bit Amlogic S905 • AndroidTVBOX.eu). Android says that it´s p201 board. But I have LE configuration with gxbb_p200_1G_1Gbit_RealtekWiFi.dtb device tree and everything works great.
I have a mxv+ as well i tried that gxbb_p200_1G_1Gbit_RealtekWiFi.dtb and my ethernet won`t pull an IP dchp now, what build are you running it on .... also does your clock still work
