Hi Guys, How did you add the support for this switch in the kernel. I am using similar switch KSZ8873, and i have selected this in kernel config also. But when the kernel is booting I get a error message "„no PHY, assuming direct connection to switch". Looks like while scanning for phy the kernel is not finding anything. In my device tree its using generic phy. I am new to this can some one please share some information on this.

Thanks

I faced the same problem, i had the message "no PHY, assuming direct connection to switch".

I modified my dts to add mdio node and now i get only:

IP-Config: Failed to open eth1

IP-Config: Device `eth1' not found

&fec2 {

        pinctrl-names = "default";

        pinctrl-0 = <&pinctrl_enet2>;

        phy-mode = "rmii";

        phy-handle = <&ethphy2>;

        phy-reset-gpios = <&gpio2 7 GPIO_ACTIVE_LOW>; /* GPIO2_7 */

        status = "okay";

        mdio {

                #address-cells = <1>;

                #size-cells = <0>;

                ethphy2: ethernet-phy@0 {

                        compatible = "micrel,ksz8081";

                        device_type = "ethernet-phy";

                        reg = <0>;

                };

        };

};

I try to boot on NFS. The kernel is well load throught TFTP but impossible to load rootfs.

Did you solved your problem?

Did you ever fix this issue? I am trying to connect to a KSZ9031 PHY device but getting the same type of error message.

IP-Config: Failed to open eth0

IP-Config: No network devices available

Yes, i solved my problem, in fec driver 3.14.28, mdio node nedded to be in fec1. That was the only mistake.
