Arria 10 Ethernet Connection Issue

Honored Contributor I

Hi everyone, 


I am having an issue with the ethernet connection dropping on the Arria 10 board after reprogramming the board with a bit file. On start-up I can ping the host computer from Linux running on the board or from the command line to the device and receive a reply. After reprogramming, any pings between the host computer and board receive no reply. Running ifconfig in the Linux terminal after reprogramming the board still shows the same ip address attached to the board before the reprogram. I've solved the issue in the past by power-cycling the board, closing and reopening Quartus, and programming the board again, but this method only works about 10% of the time. I can't reproduce why the issue is happening or why my fix sometimes works. Does anyone have experience with this or a similar issue? 


Thanks for any help/insight you can provide.
