    Hi Nan,

    Please try the following procedure.

    1) On LS_SERDES_CONTROL_3, set bits 2 and 3.  Do this for all lanes where you would like local loopback.

    2) On HS_TP_CONTROL, try setting bits 3:0 to either 0100 or 1100.  I think one of these should enable local loopback, although it's not clear which based on the register map description.

    Thanks,

    Drew
