zhangjie,

You did not need to double post - or address an individual because everyone sees these posts and might reply if they can help. Sure, you can address the previous replier to a post of yours but no need for a double entry.

The error can be caused by compiler optimization. Also, bit 31 is set of the address (being a non-cached pointer) and that may be causing the symbol lookup to fail.

udp_send can fail if ARP responses are not working. Packets cannot be sent until the address is resolved by ARP. However, I think a ping causes ARP to be resolved so UDP should work too. Can you receive UDP and just not send? Wireshark will show you the ARP resolution (Who has?). Also check your firewall - I'm not sure which side of it Wireshark is watching.

Regards,
