What are the messages?

I guess you configured the IP address statically on your board. Please
make sure that the board is in the same network. For example, if you use
192.168.1.0/24 as your network, you won't be able to ping 192.168.0.222
unless you have defined some routing or a separate IP address in the
192.168.0.0/24 network.

Well, I can't really help you with that. Also, it seems you are using
the current lwip port available in the CVS (or ecos 3.0). I have not
used that port, as it was rather dated, so I ported a newer lwip
version. You could try my port too, a snapshot is available:
