Hello all, thanks for the information. I will come back to this now. I have the data sheet of the PHY and also know about MDIO IF. The question is only, what I do have to do, to get the PHY ready for sending.( I have experience with former projects regarding Xilinx Virtex + PowerPC and Spartan + MAC, but I did not send data directly to PHYs withut a MAC yet. For test purposes, I tried to activate the packet sender and the auto loop function available with the PHY in the last project but did not succeed, however. I did not find out finally, if it was a config problem or a hardware problem of that particular platform.)

Assuming, the DE2-115 is ok and working, I want to repeat this now for Altera Cyclone IV - as said, without a MAC.

I found that basic configuration can be achieved by only the hard wired config if done correctly.

Now I wonder, how I can establish a logical link to a switch?
