hi,3c120n_88e1111 no data trans.

hi ,friends,

I have a problem, when use the 3c120n development board,the 88e1111 IC only can receive,but not send.

I see the receive timing

f 5 5 5 5 ... 5 d + ipv4.

and I send IPv4 frome 88e1111 to ethernet ,but no data is recieved in computer.

what's "f 5 5 5 ... 5 d"

why data can't be sended?

    Is the address of the PHY is correct? I think the PHY is connected to the "00000" address. You can download the web server reference design and test it.

    AFAIK quartus allows to generate a time-limited .sof file. At least mine quartus does, but I have to leave JTAG connected. What quartus software do You use?

    Update Your software and also update Your licences. This will allow time-limited .sof file generation and also newer (less bugs) ip cores.
