Hi,

I monitored the in/out traffic using Wireshark and it shows there is ARP from PC (ip:192.168.0.2) but no trace of ARP respond from the board (ip:192.168.0.4). I know the board ethernet port works with it's demo "Board Update Portal" test app. You are right! At this point, it could be the Hardware level or the kernel Config error. To begin, I tried signal tap the ethernet interface and very quickly to realize the transmit (enet_tx_en) and receive control (enet_rx_dv) signals stay low constantly. Are both signal supposedly not stay low? Attached is both signaltap and wireshark screen capture. Any help is greatly appreciated.

At first, please check the 'link pulse'. Does your PC is linking with your board under the desired speed? And the enet_gtx_clk (125MHz GMII Transmit Clock?) is moving?
