Most likely not. There is support for resizing the VRAM BAR, but usually you can only make it larger and not smaller.
Please give me the output of "sudo setpci -s 0001:01:00.0 ECAP15+4.l ECAP15+8.l" if you want to double check that.
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. That problem is not really E9171 related. You might want to ask NXP for that maybe.
Sorry, no idea if that is correct or not. You need to ask NXP for help with that.
Okay no problem. 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.

Then I canged 256 MB to 4GB in .dtsi and U-boot conf file. I also changed 64KB I/O size to 1MB . When I do this, I wasn't able to reach the linux console because board was freezing. But driver was successfull at this time. I already mentioned successfull driver console logs up.Christian König <ckoenig.leichtzumerken@xxxxxxxxx>, 2 Ara 2019 Pzt, 15:28 tarihinde şunu yazdı:
Hi Yusuf,
Am 02.12.19 um 12:41 schrieb Yusuf Altıparmak:
My embedded board is freezing when I put E9171 on PCIe. What is the meaning of Unrecoverable Machine Check error about GPU?
Well see the explanation on Wikipedia for example: https://en.wikipedia.org/wiki/Machine-check_exception
In general it means you have messed up something in your hardware configuration.
Could PCIe settings in .dts file cause this problem?
Possible, but rather unlikely. My best guess is that it is some problem with the power supply.
If it is, is there any sample PCIe configuration for E9171?
The E9171 is just a PCIe device, so the dtsi is actually rather uninteresting. What we really need is a full dmesg and maybe lspci output would help as well.

Christian.
Hi Christian,
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.
