Hi,
I am using LX2160A in my custom hardware. i need to configure serdes 1 first 2 lines as SGMII(lane 0 and lane 1). I have added the below snippet in my "fsl-lx2160a-rdb.dts" file.
&dpmac3 {
status = "okay";
phy-connection-type = "sgmii";
managed = "in-band-status";
};
&dpmac4 {
status = "okay";
phy-connection-type = "sgmii";
managed = "in-band-status";
};
I can see link is UP and RUNNING, but still i can't able to ping the other end. LX2160A is directly connected to Ethernet Switch without any external phy. While performing ping test TX packets increases where RX remains 0.

Can someone help on this.
