I am using AXI Ethernet subsystem ip and configured it in SGMII mode for connected to MARVEL IC 88E1111-B2-BAB1I000. The PHY address has been set to 0 is IP. I have used the SDK Ethernet example design available for the testing.
I have checked the GTH clock which is 125MHz and is fine and PLL lock has happened. But I am not able to see the MDC clock being generated. Also I have probed the user clocks through ILA and it looks fine. I am not able debug further.
can you tell me the possible reasons for MDC clock for not getting generated ?
Also suggest further ways for debugging the MDC clock.
Thanks and Regards

Since I have used SDK Ethernet example design, I have put mdc clock in trigger in ILA and then run the application. But I didn't get any clock on mdc pin.
