I'm afraid Ethernet is a bit outside our area of expertise, maybe someone else on this forum can help you, or you've got to the Zephyr project for help. I know they've got a mailing list and a Slack or Discord channel.

I assume problem exists in the configuration of Zephyr. I might be missing to enable some parts of TCP stack. But I am unable to track it down.

Well does the problem exist in the nRF device or the modem?

Yeah, I have enabled debug logs in Zephyr and captured logs from terminal application. Please find attached log file and let me know whether it helps or not. Also let me know in case you need more information.

Thanks & Regards,

Do you have any logs from the modem or the nRF device?

This ethernet sniffer trace only tells us that you got no reply to your ping.

I had screenshot of wireshark log. Following are the sequence of events that you can observe in wireshark:

* IP Address of my device is 10.128.8.16 and IP Address of the PC from which I am initiating ping is 10.128.8.103.

* Wireshark is running on PC with IP address 10.128.8.103.

* From the attached image we can observe that PC has sent ping request to my device.

* After that, device has sent a broadcast message seeking for the owner of IP Address 10.128.8.103(PC).

* Then, PC has responded with its MAC ID.

These are the sequence of events that are occurring. I hope this log helps you in understanding the situation. Please let me know if you need more information.

Thanks & Regards,

You need to isolate the issue. Is it it a HW issue, wrong configuration of the Ethernet module, or is the Ethernet driver running on the nRF not behaving as you'd expect.

Do you have any debug logs, SPI sniffer traces, etc?
