Hi Tom Zhang,

Thanks for your query.

Can you please share the UART console logs and wireshark captures?

Hi Ashwani,

Thank you for your reply, please check the running log and wireshark capture.

ping test.zip

Hi Tom Zhang,

UART console logs shows static IP address and MAC address as well.

MAC port link is also up.

Which example are you running here?

Regards

Ashwani

Hi Ashwani,

I refer to the example "enet_lwip_cpsw" on am64x-sk board, with sdk version 10.00.00.20.

Hi Ashwani,

I follow the thread but still not resolve the issue.

I'm able to ping other host with my pc, but fail to ping the board in same network environment.

Hi Tom,

Can you check CPSW stats and PHY stats and check where the packets are dropping?

or

These are reaching host but application is not responding them properly?

Regards

Ashwani

Hi Ashwani,

Thank you for your reply.

Could you help to guide me how to enable the CPSW stats and PHY stats in the sdk? 

for CPSW please follow below FAQ.
