i have xilinx zynq xc020 soc . i am new to the PTP implementation.
in my design i have three ethernet one is connected to PS through mii.one more is connected to gmii_to_rgmii ip core through zynq emii. one more is connected to axi-1G/2.5G ethernet subsystem. The external Phy is microchip(KSZ9031RNX). is same for three ethernet's.
Is there any possibility is there to implement the PTP in this system.if there is any way please give me the solution for this ?

PTP is zynq GEM is not supported. It's not accurate enough.
You can use AXI Ethernet subsystem to implement PTP. For more info, please refer to PG138.

Thank you for responding to my query.
In my design i have AXI-subsytem ethernet with GMII interface . Is it posible to implemnet in GMII interface for PTP core.
