Ethernet Example Design on Cyclone III Dev Board (3C120F780)

IIRC there is something special to do to set up the interface in rgmii mode, as it is on the 3C120 kit. I don't remember it exactly but a search on the forum could help.

Looking in the software templates in Quartus 10.1 they seem to have created special rgmii templates, maybe you can try those.

Hi,

I tried out the SimpleSocketServer_RGMII and this one is running. It seems so, that the 3C120 Dev Board needs a RGMII-Design in Nios.

Thanks a lot to Daixiwen! You gave me the special tip.

Possibly Altera adds the RGMII code to the 3c120-board tuturial.

Best Regards

Mark

To anyone who's curious, I think this was the solution:

This a all things you need, If it help for you. Thanks to me so much

Above all, You should test define in "simple_socket_server.h"

there a numerous at "web_server.h"

in addition, I think that define for IP address have a problem.

please posted full code it will show how code error.

Hi all,

i got a NEEK 3c25 board, i've followed instructions step by step but at the end when i launch Eclipse project the console output get stuck with:

PHY INFO: waiting on PHY link...

and nothing happens, no IP is assigned to the board and lights on Ethernet connector of the NEEK board remains on with no blinking.

If i attach/detach ethernet plug to NEEK board it's the same..

My configuration is PC LAN with DHCP and NEEK LAN connected to a switch.

I've tried also to uncheck dhcp in BSD properties but this action lead to impossility to compile eclipse project i have a lot of errors...

Hi Mark,

May be this thread is too old. But I am also stuck with the same problem now. I have a relatively old Cyclone III FPGA board, bought in 2009 I think. It could not run the "simple_socket_server_rgmii" example provided in "altera\12.1\nios2eds\examples\software". It cannot run even the recently downloaded example from: http://www.altera.com/support/examples/nios2/exm-using-nichestack.html . I added -DTSE_MY_SYSTEM flag and also commented out "IOWR(&pmac->mdio1.reg14, 0, dat); " line as suggested here: http://www.niosii.com/support/kdb/solutions/rd01042012_567.html

The "tse_my_system.c" file is already provided in the recent example with the necessary code. Do you have any idea what might have gone wrong? Do I need to change any settings on my computer?

Thanks,
