ADSP-SC584 Running LwIP INETD application on SC584-Ezkit. Not Enabling MAC

I am trying to run LwIP INETD application on ADSP-SC584 Ezkit board using ICE-1000 Emulator in Debug mode. 

I have referred this link https://ez.analog.com/dsp/sharc-processors/adsp-sc5xxadsp-215xx/w/documents/5044/lwip-on-sc584-ezkit

But during execution i am getting "Failed to enable EMAC" with error code 6 (ADI_ETHER_RESULT_PHYINIT_FAILED). 

On the same board I am able to run power on self test for Ethernet successfully with EMAC enabled. Can anyone please help or provide any suggestion on how to resolve the issue??

Thanks.
