If I face this kind of error, I'll capture the traffic with the WireShark on the source PC and the destination PC.

so the destination PC received and replied ICMP packets? did you take a look at the contents of the ICMP packets? How frequently did you send ICMP ping reset?

I am continuously sending ping requests from both the side from the PC & from the board, but out of 20-30 requests I am getting response for 2-3 requests in about 2 -3 seconds delay. For rest cases I am getting host unreachable on board side & request timed out on the pc side..!!!
