OpenCore Emac dosen't work!

I have a OpenCore EMAC bought from Microtronix. I installed and built it in Quartus 4.2 and Nios II IDE 1.1 according to Linux and OpenCore guide manual and then uploaded it to Nios 2 Evaluation Kit, but even though I could log in Linux through nios2 terminal successfully, I could never connect it to the network! What's the problem? Because of my doubt of the procedures of doing such things, I did it repetitively but had the same results! In addition, after logging in Linux I set up IP address with the command like '#ifconfig eth0 xxx.xxx.xxx.xxx netmask 255.255.0.0' but after CPU reset all IP settings are also reset! The OpenCore EMAC does not work ever even before or after IP setup. Please help me!?

    Have you tried the OpenCore MAC SOPC component from Altera which you get freely? (o;

    I purchased it from Microtronix Corporation, not Altera. I have tried to do all things specified by Linux Manual and Microtronix's OpenCore EMAC method. But I can't operate it on Nios II evaluation kit. If Microtronix-related engineer see my complaint about EMAC, Why does not she/he respond it? At least, I think they must tell me about that problem.

    Well... "#ifconfing eth0 xxxx...." is not related with EMAC core..

    I think you should re-make "ramdisk" image.(or boot load image)

    Are you korean?

    If you are, and also wanna more info. send me e-mail.

    Good luck to you ^^

    Can you post a copy of the boot messages and also a copy of any output that comes after your ifconfig command.

    Thanks,
