    Device Tree Configuration of Picozed

    maggi.lgi@gmail.com

      Hi,

       

      I try to configure device tree of Petalinux platform on Picozed board (PicoZed_7015_Rev_C03 S/N: BD-Z7PZP-7Z015I-G). The board is plugged on PicoZed FMC Carrier Gen2 and the PHY device is marvell,88e1512.

      Unfortunately  the ethernet device is not recognized by operating system; at the boot the message "Cannot find eth0 device" appear.

      In the following my device tree "system-conf.dtsi" file:

       

      /include/ "system-conf.dtsi"

      / {

      };

      &gem0 {

           status = "okay";

           phy-mode = "rgmii-id";

           phy-handle = <&phy0>;

           mdio {

                     #address-cells = <1>;

                     #size-cells = <0>;

                     phy0: phy@0 {

                     compatible = "marvell,88e1512";

                     device_type = "ethernet-phy";

                     reg = <0>;

                     } ;

           } ;

      };

       

      Can sombody check if the device tree configuration is ok ?

       

      Thanks

       

      Best regards
