Hi Team,

I need help to very my device tree and as it is not attached to our custom board, and we are getting ping issue.

below is my device tree: 29 mdio-nexus@1,3 { 30 mdio0@87e005003800 { 31 mdio-in-kernel; 32 phy0: ethernet-phy0 { 33 reg = <0x00> ; //provide correct reg that the device is using, check datasheet for this. 34 //compatible = "ti, ethernet-phy-id2000.a231-c22"; 35 compatible = "ti,2000a231", "ethernet-phy-ieee802.3-c22"; 36 }; 37 // clock-freq = <16666666>; 38 }; 39 }; 40 41 mdio0_uio { 42 compatible = "marvell,mvmdio-uio"; 43 mii-bus = <&mdio0>; 44 }; 45 46 rpm@1 { / GSERM1 / 47 ethernetB0: sgmii@10 { 48 reg = <0>; 49 phy-handle = <&phy0>; 50 // qsfp-slot = <&qsfp_1>; 51 };

after adding this on kernel we are not getting ping with from particular ethernet. Please let us know to add more info if required

Hi Himarawa,

Apologies for the delay in response. Could you let me know what version of Linux you are using? The command 'uname -r' will tell you. Could you also run the following command: 'dmesg | grep -i mdio' and share the output?

I understand that ping isn't working, but is the DP83867 able to link up when the cable is connected? Is register access available?
