SGMII Kernel Configuration

Hi,

I am trying to configure the Gigabit Ethernet on Linux kernel on my board using P1012 microprocessor, it seems that the configuration is correctly done but I keep getting “ifconfig: SIOCSIFFLAGS: Cannot assign requested address” when trying to configure ips for eth0 or eth1.

My configuration is:

 

 

And my device tree:

mdio@24000 {

                        #address-cells = <0x00000001>;

                        #size-cells = <0x00000000>;

                        compatible = "fsl,etsec2-mdio";

And this is the console output I get related to SGMII configuration:

I have also checked TBI and PHY status registers and both have the auto negotiation complete bit set to 1. Can anybody help me with this problem?

 

Thanks in advance,

Maria
