No MDIO

[Altera_Forum]

Hi, 

 I am trying to send data from Cyclone III development board to another (same) board using Ethernet connection.  Data is transmitted successfully from the sending board to the receiving one.   My question is:  Is it possible to connect the two boards without enabling the MDIO option in the TSE MAC?  Thanks in advance  Best Regards

Theorically yes, so You would control the PHY by Yourself. But why do You want to disable it? The core won't be able to communicate with the PHY, e.g. set required registers, reset the PHY, etc...

Well yes, but still You have to control the PHY. MDIO has nothing to do with the transmission itself.
