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.

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.
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.
this is lspci -v when GPU
is plugged and Memory size is
256 MB.
