Hi Vamsi_21,

Could you try enable NPDME option and try testing again on hardware?

Best regards,

zying

    Hi,

    I have enabled NPDME option and generated the example design.
    I have given the pin assignments as follows
    NAME pin assigned
    mm_clk BD24
    ref_clk_10g AN8 (modified using clock controller)
    While testing on the hardware , i am getting the below error from system console.
    error:TTK failed reading from PHY slave_2000, cannot enable TTK functionality for this PHY. Please verify the reconfig_clk is running and ensure this PHY is not stuck in reset.
