Code:

sudo dtc -I dts -O dtb -o /boot/overlays/gt911.dtbo GT9110_overlay.dts
That's not sufficient for an overlay - you need at least the "-@" parameter.

My usual build line for overlays is:

Code:

dtc -@ -Hepapr -I dts -O dtb -o whatever.dtbo whatever-overlay.dts
but using the "kdtc" tool in our utils repo (https://github.com/pelwell/utils/tree/kdtc/kdtc) you can simplify that to:

Code:

kdtc whatever-overlay.dts whatever.dtbo
