how to make mac10 work normal in ls1046ardb

[940785652]

   I have a board and it has the same hardware between mac9 and mac10.mac9 is fine,but mac10's Autonegotiation has a problem which doesn't work when  network interface is connected,and it shows link up,but ping is failed,but ifconfig fm1-mac10 down,ifconfig fm1-mac10 up,mac10 is ok.

   how to modify code to solve this probelm?

Hello siyao qi,

Which version LSDK are you using? I use LSDK 1906, didn't reproduce your problem.

Please refer to my following procedure.

root@localhost:~# ifconfig fm1-mac10 100.10.1.9

Connect MAC10 Ethernet interface to the server PC

Hello,yiping:

I solve it,I write mac10's device tree as mac9,mac10 works as i say,mac9 works normally.

but mac10 works normally when i delete the function phy_start_machine.

but I don't know why it is .can you tell me why it is ?

Hello siyao qi,

On LS1046ARDB, interface ethernet@f2000 is 10G SFP (phy-less) port.

The dts should be defined as the following.

        ethernet@f2000 { /* 10GEC2 */
                fixed-link = <0 1 1000 0 0>;
                phy-connection-type = "xgmii";
        };

Thanks,

Yiping
