But what error are you getting? What are the symptoms of your problem? The GMII interface (the 8-bit bus) is inconsequential to PHY configuration and management. Only the MDC/MDIO bus is used. Therefore the PHY id should be quite readable. What version of Linux are you using? Please describe what the kernel prints out when you boot, and when you try to bring up the interface (assuming you don't do that at boot). Andy
