You have to take your PHY out of reset. How to do this depends on your board. On the ADS8260 the PHY reset line goes to the BCSR and you must write the above to BCSR register 1 to tell it to change the pin level. On your board you may need to use GPIO, or you may need to do nothing at all. Read your schematics! Regards, Alex
