Re: can get DHCP IP address, but cannot ping


hello, Andrew

Thank you very much.
I run tcpdump on the host and get the following screen shot. It seems host has received the package and reponded. But I am not confident because I am not farmilar to tcpdump. Could please give me further advice?

192.168.0.59 is the host and 192.169.0.198 is the target.

hello, everyone

I ported SMSC LAN91CXX driver to my sh7760 board. When I boot my board, the
DHCP IP address can be gotten. But I failed to ping to the host. Could you
please give me any advice?
the following is the screen shot. I am sorry the message is long because I
redefined the DEBUG value to output debug message.
Thank you!

Run tcpdump on the host and see if it is receving the ICMP echo request message and repsonding with ICMP echo response messages.
