Okay I'll try it tomorrow. What does the " sudo setpci -s 0001:01:00.0 ECAP15+4.l ECAP15+8.l" command exactly do ? > Well you rather need to ask if anybody has sample PCIe configuration for > GPUs in general.

At least I know what is the missing point now. The problem is probably because of the .dtsi and u-boot config files. Memory ranges are overwriting like you said. I'll ask nxp to take some sample PCIe configuration for GPUs. Thank you for your interest Christian.
