Dan Lyle Posted January 7, 2020 Share Posted January 7, 2020 Hello all, I am new to Ethernet and I am trying to learn how to use it on the nexys 4 ddr. I am trying to avoid using ip cores. I am not seeing packets that I am transmitting to the PC on wireshark. Currently the link light led on the nexys 4 ddr board is blinking meaning that I do not have a valid link but the PHY is detecting activity. I am unsure that I am correctly forming a IEEE 802.3 packet in my code and that I am using the PHY IC correctly. currently in my code I am just creating a fixed packet in code and just transmitting that to the PHY. Any help will be appreciated. I have attached my code. I am only creating an Ethernet packet and not a ip or UDP packet should I implement these as well or is just an ethernet packet okay?

D@n Posted January 8, 2020 Share Posted January 8, 2020 @Dan Lyle, I assume this is your post on Reddit as well? Rather than answering twice, I'll let you find my answer there. Dan Link to comment Share on other sites More sharing options...
