    Jinfei,
    Posting to a previously answered thread may not get your post noticed so I moved your post to a new thread.

    Have you strapped the LAN8710 address pins correctly? Please review section 5.3.9.1 of the LAN8710 data manual for details on how to correctly do so. As for the LAN8710 implementation, MDIO is only 2 pins, a clock and a data...if you had this wrong the interface wouldn't work at all. That said, the BeagleBone Black uses LAN8710...please review it for an example implementation: https://github.com/CircuitCo/BeagleBone-Black/blob/master/BBB_SCH.pdf?raw=true
