SGMII Kernel Configuration

masasi — Mon, 06 Jul 2015 17:31:11 GMT

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";

device_type= "ethernet-phy";

};

};

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,

Hello Maria Saiz,

I found an obvious problem in your Kernel boot log, you didn't specify MAC addresses for eth0 and eth1.

Please configure MAC addresses for them in u-boot, here is an example.

eth10addr=00:E0:0C:00:24:0a

eth11addr=00:E0:0C:00:24:0b

eth12addr=00:E0:0C:00:24:0c

eth13addr=00:E0:0C:00:24:0d

eth14addr=00:E0:0C:00:24:0e

eth15addr=00:E0:0C:00:24:0f

eth1addr=00:E0:0C:00:24:01

eth2addr=00:E0:0C:00:24:02

eth3addr=00:E0:0C:00:24:03

eth4addr=00:E0:0C:00:24:04

eth5addr=00:E0:0C:00:24:05

eth6addr=00:E0:0C:00:24:06

eth7addr=00:E0:0C:00:24:07

eth8addr=00:E0:0C:00:24:08

eth9addr=00:E0:0C:00:24:09

Have a great day,
Yiping

Thank you for your help!!

I was configuring MAC address through Device Tree but did not take into account that whatever I write on the dtb file, the u-boot always rewrites Device Tree MAC addresses with the ones it has been configured with.

I changed uboot MAC addresses and everything worked fine.

Thanks again!
