cannot ping serverip from u-boot.

[Mahesh Kurapati]

Hello Jonathan, 

We have two NICs.  One is connected to i350 for NC-SI, and other one is over the Marvel PHY on which I am trying to connect.  ethact variable is set correctly. I have not tried the NC-SI Interface @1e660000).

Thank you
Mahesh

Does your system have two NICs?

Is your network cable plugged into the NIC specified by the ethact U-Boot setting?

Have you tried changing the ethact line to point to the second NIC address (e.g. ethernet at 1e690000)?
