    Hi Bulkesh,

    First verify the link is running on cable side by reading register #1. 

    If the link is up on the cable side, then the problem might be on RGMII side, please make sure PHY is in correct RGMII mode, (shift or align) make sure you select the correct one for your application. 

    Best, 

    Alon
