Hello, I can’t enable gpu in DietPi on OPI Zero2W.
I edited dtb file and enabled gpu and install panfrost drivers but there no gpu in GL, also tried ovelays. It was detected by panfrost but not by OpenGL

root@DietPi:/# dmesg | grep panfrost

Hi

How did you applied the overlay ?

With the command G-config-inject ?

3

yes, as it is written here

4

Are you sûre this overlay i’s avalaible with your kernel ?

A screenshoot of your dtb overlay folder ?

5

I think so, I found this.

If you edited your dtb file
Does it seems equal to this fragment

fragment@6 {
		target-path = "/soc";
		__overlay__ {
			gpu: gpu {
			                       compatible = "allwinner,sun50i-h616-mali", "arm,mali-bifrost";
			                       status = "okay";
			                       };
			 };
	};

Thank you for your help and sorry for wasting your time. The problem was only my inexperience with the Linux and now I’ve figured it out.. i’m sorry.
