Linux/AM3357: Ethernet configuration

Hello Sir,

Sir I could able to get the activity lights on Ethernet port, but in Linux I am not able to get the eth0 interface.

I am not able to access the Ethernet registers also.

I can see the gmii sel register, I can see the mac_id0/1 registers but what's wrong with Ethernet registets

Hello Sir,

I am sorry I couldn't able to give full detailed description as i was travelling,

ours is the custom board based on am3357 evm.

 Here is the Uboot and Kernel Boot log

After the linux is booted, both the LEDs at transceiver were on.

we are using Atheros AR8031  transceiver, according to the datasheet of AR8031

when both LEDs are on at the transceiver LINK_1000M is ON and it will be active when it blinks.

Here are some more information,

Hello Sir,

Thank you

I have applied the below patch, which i had found in forum only, after adding that patch, i am able to get eth0 interface.

even after getting that i am not able to ping.

after adding this results are quite positive, nut still MDIO is a problem.

please check the txt file which i have added below,
