Hello

Excuse my English in advance.

I'm also using DE4 and DUAL XAUI TO SFP+ HSMC board, and have almost the same problem as you have. Unfortunately DUAL XAUI TO SFP+ HSMC board datasheet I've received from Altera, don't contain any information about BCM8727 and its registers. But, I've found list of MDIO registers in DP83848VYB datasheet. Maybe it will help you. And could you please tell me, what are these "magic number" that you send over MDIO interface?
