RTL8119I PCIE LAN mc-err error on Orin NX

Hi Nvidia,

I’m porting realtek RTL8119I-CG on Orin NX module and our custom carrier board.

The RTL8119I-CG is connected Option2 PCIe3 x1 (C9). (The Green line in picture.)

PCIE3639×694 97.3 KB

I follow Nvidia document to modify the dts file.

p3767.conf.common

ODMDATA="gbe-uphy-config-9,hsstp-lane-map-3,hsio-uphy-config-0";

cvb/tegra234-p3509-a02-pcie.dtsi

pcie@141e0000 { /* C7x1 node */

                status = "okay";

                phys = <&p2u_gbe_0>;

                phy-names = "p2u-0";

        };



        pcie@140c0000 { /* C9x1 */

                status = "okay";

                phys = <&p2u_gbe_1>;

                phy-names = "p2u-0";

        };

But I got following errors when system boot up.

I can get eth0 and pci device in the lspci.

I add the mac address to eth0 but it still can’t connect ethernet when I plug in the eth cable.

Does anyone can help us?

Thanks.
