    Hi guys:
    I was stuck..
    My GIG PHY can only work at 100M mode.
    At 1000M mode, PHY can only receive ,but can not transmit
    data.
    I am sure software and driver are right,and all TX and Rx
    lines are terminated, clock is OK.
    Could anyone provide advices?
    Thanks a lot

    The TX clock for gig goes the other way and is on another pin (probably
    called something like GTXCLK).
