Venz v12 ultra device tree for 19.5

I have a Venz v12 ultra (V12 ULTRA) which uses the Amlogic S912 soc.

I am unsure which device tree i should be using. In the past i used gxm_q201_3g_1gbit.dtb but this one doenst seem to be present in the device tree folder after creating a fresh installation media.

I have tried both the gxl_p212_2g_slowemmc.dtb and gxl_p212_3g.dtb. This does seem to work initially as i see the core elec logo and some initial install log lines on the screen but after a while it only shows the core elec logo and doenst do anything after that.

Can anyone please advise?

GXM is no longer supported device.

Use latest compatible version from topic above.
