Hi!
I have a board with Virtex-6 and C6474, I need to connect them via emac. As I can see on a my scheme, the only 6474 EMAC pins that are enabled are SGMIIRXN, SGMIIRXP, SGMIITXN, SGMIITXP. The MDIO pin is disabled. Is it necessary to do any PHY initialization to make my Xilinx MAC-to-DSP MAC connection? Or it's quite enough to config SGMII registers and interrupts.
Unfortunately all existing EMAC examples are either loopback or on physical layer - it don't fit to my case.
