Hi,

i developed a Ethernet UDP\IP module via RMII using the device LAN8720A on the Nexsys DDR board
my problem is that i can see the data only when i using wireshark wich put the NIC in promiscuous mode when i try to the debug the problem using logic analyzer i see the packet structure is as i want to first there is a preamble,SFD, my payload and FCS
did i miss something?
thanks for the help

Are you sure you're using correct destination and source MAC addresses in your packets? Can you post a pcap dump?

I also have a suspicion about ARP support (use tcpdump/wireshark to check what queries are sent by your host machine) but the first thing is to check addresses and checksums.
