Orin MGBE3 start up error

[user98631]

We used MGBE3. My dtb is configured as following:

/* MGBE - D */
ethernet@6B10000 {
	status = "okay";
	nvidia,mac-addr-idx = <3>;
	nvidia,max-platform-mtu = <16383>;
	/* 0=enable, 1=disable */
	nvidia,pause_frames = <0>;
	//phy-mode = "10gbase-r";
	nvidia,uphy-gbe-mode = <1>;
	/* 0:XFI 10G, 1:XFI 5G, 2:USXGMII 10G, 3:USXGMII 5G */
	nvidia,phy-iface-mode = <2>;
	
	fixed-link{
		speed = <10000>;
		full-duplex;
	};
};

When start up, the following log output periodically:
[ 201.675360] [xpcs_lane_bring_up][416][type:0x4][loga-0x0] Failed to get PCS block lock

Can you help analyze the reason?

Hi,

Sorry that config #3 is not supported. Please move to config #1 or config #2.

Hi, WayneWWW:
We used CONFIG1: gbe-uphy-config-22. The port I used is MGBE3. And NVIDIA doc says that Both CONFIG1 and CONFIG3 support 4 MGBE.

Is the 4 MGBEs really supported on CONFIG1?

[WayneWWW]

Please refer to the design guide again. We only support config 1 as same as the devkit.
