Hello Christian,
I solved this problem weeks ago. The problem was, the system I use could
only give 256 MB address range but GPU was demanding more. Even if I give 4
GB, PCIe slot is only having 256 MB, nothing more. I put a empty area that
is between PCIe2 ( GPU was connected to this) and PCIe3
Right now I am trying to increase MMIO size config to 512 MB
What you could try as well is to use the size 320MB for the MMIO. Those
ranges usually don't need to be a power of two (only the BARs itself are
a power of two) and this way it might even be easier to fit everything
together.

Yes unfortunately there is nothing remained to about GPU side.

Exactly as I thought. The hardware does support BAR resize, but
unfortunately 256MB is already the minimum.
Sorry, but there isn't anything I could do from the GPU drivers point of
view.
The only good news I have is that 256M+2M+512K+128K=260M address space
should be

My "setpci -s 0001:01:00.0 ECAP15+4.l ECAP15+8.l" output is;

That is an expected result. 256MB is not enough for the VRAM BAR
and the doorbell BAR to fit into. But you can still use VGA
emulation that way if I'm not completely mistaken.

Hmm, then what procedure should I follow to take a VGA output. It seems
Graphic Card does not have a VGA output.
Hi Yusuf,
At first, I am using NXP T1042D4RDB-64B which has 256 MB PCIe buffer
according to its. PCIe memory range was arranged to 256 MB in .dts
file and in U-boot configuration file. Driver was giving error with
exit code -12 (OUT_OF_MEMORY). But I was able to reach the linux console.

Could PCIe settings in .dts file cause this problem? If it is, is there any
sample PCIe configuration for E9171? I attached my dts file.
