[U-Boot-Users] [newbie]: ping implementation

Hi all, and sorry again for wasting time with my silly questions ;)

Thanks in andvance for your answers, always quick, ready and complete!

The question is: I managed to boot the MP8260ADS with u-boot. I configured the network. I tried to ping it from the host pc and get "host unreachable" message. Instead if i ping the host from the board i get only "the host is alive" message. I don't think this is completely normal. Am I wrong? Another matter is the "Bad Magic Number" notice just before the u-boot prompt. I searched for help about it but did not find anything. What does it mean?

Thanks a lot for your patience

Lele
