Although the computer IP address has been configured according to the tutorial, the computer could still not connect to the board via Ethernet. We use Wireshark to record Ethernet packages and found that ARP packages got no response from the board. Then we manually set the ARP table and connect the board using mmWave studio. In Wireshark we could see UDP packets sent by the laptop, but there is no UDP packets from the board. There is no other error message or indicator. Could you please let me know what might be the solution?
