@SuperAviation001 i think your fb address is different. This is from downstream:

		bootloader_fb {
			compatible = "exynos,fb_handover";
			reg = <0x00 0xf9800000 0x23d2000>;
			phandle = <0xd9>;
		};

a13_eur_open_w00_r00.dts:

				bootloader_fb {
					compatible = "exynos,fb_handover";
					reg = <0x00 0xfa000000 0xd00000>;
					phandle = <0x42>;
				};

0xf9800000 results in a black screen and nothing more.

btw, reopened this pr, didnt need to change anything else.

Yes, i tested with 0xfa000000 and it started outputting the uniloader stuff on screen
0xfa000000 is also the value set up by the device
