I have Board with LAN7500 connected to USB2 iMX6(Freescale). This Board is under Linux 3.10.17 Kernel. As I boot the Board and connect LAN7500 EthernetConnector to Ethernet Cable I see green LED and orange LED are on.Then make LAN7500 UP, check LINK, Ping 172.20.20.20 over eth1(LAN7500). 100% Packet loss. Can you help me in this problem?

Regards Alex
