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?
oh ,i use md_dio and md_dc pin(config6 set 0) ,phy_address"10010",register address"0x14",and read registers 0x14 data "0xffff".I think it is my error,but I can't find where the error is !!

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?
