eth1 interface is not working. I can see both eth0 and eth1 ethernet interfaces while running ifconfig command.

Please find the following boot log:

    Hi,

    I have a few questions. Is this a custom board? Which TI SDK Linux kernel are you using?

    From the snippet of the console log is there a message from the MDIO driver like the one here for phy[0] for phy on eth1? It looks like the phy for eth1 is not being detected.

    davinci_mdio 8000f00.mdio: phy[0]: device 8000f00.mdio:00, driver TI DP83867

    From the AM6442 SKEVM board I have this is what I see for the phys attached for eth0 and eth1.

    [ 1.211893] davinci_mdio 8000f00.mdio: phy[0]: device 8000f00.mdio:00, driver TI DP83867
    [ 1.220011] davinci_mdio 8000f00.mdio: phy[1]: device 8000f00.mdio:01, driver TI DP83867

    Best Regards,

    Schuyler

    Hi Schuyler,

    Yes. This is custom board based on AM64xx. We are using TI SDK8.0 with same device tree config for RGMII1 and RGMII2.

    I did not see any phy1 log from the MDIO driver.

     dmesg | grep phy
