T4240 SGMII MAC to SGMII MAC interface

[immbalu]

Hello All,

We have connected serdes 2 (sg2.1, sg2.2, sg2.3 and sg2.4) of T4240 first processor  to serdes 2 (sg2.1, sg2.2, sg2.3 and sg2.4) of second T4240 processor without using a PHY.

using the following node as devices tree:

&enet8{

        fixed-link = <2 1 1000 0 0>;

        phy-connection-type = "sgmii";

        status = "okay";

};

&enet9{

        fixed-link = <2 1 1000 0 0>;

        phy-connection-type = "sgmii";

        status = "okay";

};

&enet10{

        fixed-link = <2 1 1000 0 0>;

        phy-connection-type = "sgmii";

        status = "okay";

};

&enet11{

        fixed-link = <2 1 1000 0 0>;

        phy-connection-type = "sgmii";

        status = "okay";

};

we cant able to get link up and device status is always disabled.

i have read the phy registers and it has full duples and link speed is 1G.

any suggestions?

Thanks,

Balaji.G

Please use the modified nodes:

&enet8{

fixed-link = <0 1 1000 0 0>;

phy-connection-type = "sgmii";

};

&enet9{

fixed-link = <1 1 1000 0 0>;

phy-connection-type = "sgmii";

};

&enet10{

fixed-link = <2 1 1000 0 0>;

phy-connection-type = "sgmii";

};

&enet11{

fixed-link=<3 1 1000 0 0>;

phy-connection-type = "sgmii";

};
