I am trying to enable six overlays in Xavier like Jetson TX2 using below commands :-
echo 4 > blank
echo 0x0 > device/win_mask
echo 0x3f > device/win_mask
echo 0 > blank
But not able to enable six overlays.
I also find a way to enable six overlay via changing “win-mask=<0x3f>” in tegra194-p2822-disp.dtsi DTB file.
So, I want to know how to enable overlays in Xavier by using sysfs entry or Is DTB file change is the only option to enable overlays ?
I also seen 2 extra framebuffer node in Xavier, How I can use those /dev/fb1 and /dev/fb2 please suggest any reference for that.
