RTL8111h PCIE LAN connect error on Orin NX

[fengzan.zhang]

Hi Nvidia,

I’m porting realtek RTL8111h-CG on Orin NX module and our custom carrier board.

The RTL8111h-CG is connected PCIe2 x1 (C7).
I modify the dts file tegra234-p3509-a02-pcie.dtsi to add:
pcie@141e0000 { /* C7x1 node */
status = “okay”;
phys = <&p2u_gbe_0>;
phy-names = “p2u-0”;
};
The lspci：

As you can see the new RTL device 0007:01:00.0 load normally.But when I insert the net cable to ping, it reports a connect error log below.

Did you also change the ODMATA?

[fengzan.zhang]

No，Can you show me how to modify it?This is the default configuration in the p3767.conf.common file below.
ODMDATA=“gbe-uphy-config-8,hsstp-lane-map-3,hsio-uphy-config-0”;

please refer to document.

[fengzan.zhang]

I have chaned the ODMDATA file and had a try.I find that if our Orin NX module and our custom carrier board is connected to a computer by a router to ping, it can ping ok. But If the network cable is directly connected to the computer and modify their IP address to the same network segment, it is still impossible to ping. The log is below.What’s the reason for this?
