Hi all,I write a program to generate the ethernet packet using logic cell and implement to ENET_TXD[7:0] (i use gigabit mode). I saw the TX light on the board blinking, while I can not receive any data on my computer (I use a C socket program to receive the data). Anyone know how to fix that? My ethernet packet is followed by this rule: Preamble : 55 55 55 55 55 55 55 SFD: D5 Destination address: 00-26-9E-B4-DA-BB Source address: 00-07-ED-11-80-C9 Length: 00 64 data: 00 00 ... (one hundred 00) CRC: 6C-CC-4B-B2 I use DE3 and a HSMC-NET daughter board Thanks!
