Linux/AM5K2E04: 10G Ethernet (PSDK)

Hi,

On first glance the dtsi looks correct. Can you also post your mdio nodes from keystone-k2e.dtsi & keystone-k2e-evm.dts?

eth2 and eth3 are coming up. I could set the ipaddress for eth2 and the link shows that eth2 is up for K2E

This means that eth2 and eth3 are detected & initialized upon kernel boot. However i guess you set the ip address for eth2 with ifconfig, right?

Can you try using ifup eth2 and post the result? Also can you post the result of ping?

I tested the ping command on my EVMK2Hx running kernel 4.4.32 (SDK_03.02.00.05) on both eth interfaces (eth0 & eth1), here is the result:
On eth1:

My board is connected to a host pc & the pc ethernetl card is configured as dhcp server. The EVMK2Hx is also configured to use dhcp.

So maybe verify that you have correctly configured both devices to use static IP, or dhcp.
