Hi Andy,

Thank you for your information. So the driver is not the issue, but  
better to upgraded.

I will check the board once more. The PHY doesn't work because the  
8bit bus between MAC and PHY is locked(TX_EN and RX_DV all disabled  
from the scope's view) and also you can't see any signals exist at  
the Magnetic side(nor LED signals). It seems that only MDC/MDIO and  
CLOCK reference pin works. The PHY's ID must be read from MDC/MDIO  
interface and Clocks are right showed on the scope.

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
