Hi,

  1. Devkit means the nvidia development kit.

  2. Ok, then we will see if other alternative ways to debug this…

Could you share what you’ve done so far? I mean what DTS change and driver update have you done to the original codebase.

Hi:
1: In fact, the work I did was described at the beginning 2, 3 and 4 part.

2: About dts:

pcie@14160000 {
status = “okay”;

            nvidia,pex-wake = <&tegra_main_gpio TEGRA194_MAIN_GPIO(L, 2)
                                    GPIO_ACTIVE_LOW>;
            vddio-pex-ctl-supply = <&p3668_spmic_sd3>;
            nvidia,disable-aspm-states = <0xf>;
            //nvidia,enable-power-down;
            ......
    };
fragement-tegra-pcie-c4-dis {
                    ids = ">=3668-0001-000";
                    override@0 {
                            target = <&{/pcie@14160000}>;
                            _overlay_ {
                                    status = "okay";
                            };
                    };
            };
    };

3: about RTL811G, With the help of RTL FAE. I disabled realtek driver in NX source code, disabled eqos ether.
And update RTL driver(0010-r8168-8.045.08 Linux_r8168-8.047.05.pci-dis.notso and r8168-8.047.04) in NX by make and make install. At the suggestion of FAE, we close ASPM, and check IRQ.

4: We connect NX directly to routers.

sudo busybox udhcpc
sudo ip address add 192.168.1.201 dev eth1 : set static ip address
sudo route add default gw 192.168.1.1 : add gateway

5: We connect NX directly to PC, It has been described above.

One thing I noticed in your error log:

Jan 29 00:45:25 ec-desktop nm-connection-e[21594]: Cannot save connection due to error: Invalid setting IPv4 Settings: ipv4.addresses: this property cannot be empty for 'method=manual'
Jan 29 00:45:26 ec-desktop nm-connection-e[21594]: Cannot save connection due to error: Invalid setting IPv4 Settings: IPv4 address “” invalid
Jan 29 00:45:32 ec-desktop nm-connection-e[21594]: Cannot save connection due to error: Invalid setting IPv4 Settings: IPv4 address netmask “” invalid

I doubt an invalid value would cause the interface to not show up, but what interfaces do you see under “sudo nm-connection-editor”? One thing manual would do though is to guarantee no DHCP request would ever be attempted. You might need to “sudo apt-get install network-manager-gnome” to use nm-connection-editor.

Yes, but we want to check the patch/code directly but not just description. Is there any other change than dts change in pcie?

I also wonder why do you hit this error.

[ 94.976759] r8168 0004:01:00.0 (unnamed net_device) (uninitialized): bad mac address at /chosen/nvidia,ethernet-mac: missing.

This node should be prepared by cboot. Could you share the directory list of /proc/device-tree/chosen?

This problem has been solved, and it is the problem of the circuit. Thank you for your help. Sorry for taking up your time.
