If i activate the gpu in the device tree manually by setting the status from "disable" to "okay", then it works with the 6.6 kernel.
So there is maybe something wrong with the overlay.
I tried the "next" build (kernel 6.13.7). For the orange pi zero 3 everything worked fine and gpu overlay also.
The orange pi zero 2w instead does not boot up. The green led, which indicates that the kernel is loaded, stays off.
If i use the zero 3 image for the zero2w, the zero 2w boots up. What is wrong there?
