I think that you hit the command 'ping -c 5 192.168.3.255' from your Nios uClinux system. If so, please consider who will reply the answer. Can your network reply to the 'ping broadcast' ? MS Windows OS ignores such broadcasts and Linux can ignore those by setting 'echo "1" > /proc/sys/net/ipv4/icmp_echo_ignore_broadcasts'.
