Honored ContributorHi.. Daixiwen,
Thanks for your reminding again. I use SignalTap to check the signals and found out that enet_rx_clk and enet_tx_clk were not moving at all.. I think that's the reason i didn't see any rx data or tx data. However, what's the reason to make them like this? Since i can talk to PHY through MDIO.. is that my design problem? Just don't understand why.. I follow almost everything from the standard example of cyclone III. Can you give me some suggestions? BTW i attached the start up log here for simple socket server. Thanks again for your help. ****************************************************** nios2-terminal: connected to hardware target using JTAG UART on cable nios2-terminal: "USB-Blaster [USB-0]", device 1, instance 0 nios2-terminal: (Use the IDE stop button or Ctrl-C to terminate) =============== Software License Reminder ================ This software project uses an unlicensed version of the NicheStack TCP/IP Network Stack - Nios II Edition.
