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[2] 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 !!

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.

I use ip core of the triple speed ethernet,but it isn't permited ,so when I can not generate .sof and .pof .

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?

[Altera_Forum]

quartus 9.1 and nios 9.1, altera ip core is less。

[Altera_Forum]

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