we use XFI connect to switch, config as follow:

    ethernet@6810000 {
            status = "okay";
            nvidia,mac-addr-idx = <0>;
            nvidia,max-platform-mtu = <16383>;
            /* 0=enable, 1=disable */
            nvidia,pause_frames = <0>;
            phy-mode = "5gbase-r";
             /* 1:10G, 0:5G */
            nvidia,uphy-gbe-mode  = <0>;
            /* 0:XFI 10G, 1:XFI 5G, 2:USXGMII 10G, 3:USXGMII 5G */
            nvidia,phy-iface-mode = <1>;
            nvidia,phy-reset-gpio = <&tegra_main_gpio TEGRA234_MAIN_GPIO(Y, 1) 0>;

            fixed-link{
                    speed = <5000>;
                    full-duplex;
            };

}
and driver report error when boot up:

[ 1448.561594] [xpcs_lane_bring_up][436][type:0x4][loga-0x0] Failed to get PCS block lock
[ 1448.569758] [xpcs_init][472][type:0x4][loga-0x0] TX/RX lane bring-up failed

[ 1450.649883] [xpcs_init][472][type:0x4][loga-0x0] TX/RX lane bring-up failed

could you provide any suggestion?

I copy the config following the guide,but still report error.

ethernet@6810000 {
status = “okay”;
/* 0=enable, 1=disable /
/ 1:10G, 0:5G /
nvidia,uphy-gbe-mode = <0>;
/ 0:XFI 10G, 1:XFI 5G, 2:USXGMII 10G, 3:USXGMII 5G */
nvidia,phy-iface-mode = <1>;
nvidia,max-platform-mtu = <16383>;

            fixed-link{
                    speed = <5000>;
                    full-duplex;
            };
    };

confirm one thing: all these are modified in kernel device-tree?

please share full dmesg.

Don’t know what is the point of this question. Please elaborate.

5

I mean do I just need to modify the kernel device-tree, not dts files in bootloader?
attachment is dmsg and dts :
dmesg.txt (93.9 KB)
dtb.txt (515.9 KB)

6

kernel dts shall be sufficient.

Please also make sure hardware connection and switch firmware is correct.
