I've found that IAR use similiar flag; --no_unaligned_access. So, now I get progressed , and see packes recieved and send. Yet, for some reason althoyugh everything looks without errors in wireshark, I get "request time out" for ping from PC. I tried to ping from several PC but it didn't help. Can you see the attached pcap if anything can explain this behaviour ? Wireshark shows no errors, that's the strange thing. I see request and replies. The response time is ~40msec so I tried to change to ping -w 200 , but I see the same results. https://drive.google.com/file/d/0B22GsWueReZTZ0hfU2dRdE9rR2s/view?usp=sharing
Thank you for any suggestion.
