Ethernut and Olimex SAM7-EX256 : Registering device failed

Development Boards MicroMod
1

I have followed by viewtopic.php?t=5299&highlight=ethernut but I still cannot run Http demo on Olimex SAM7-EX256 because of RegusterDevice Failed.

Message in Hyperterminal => Nut/OS 4.2.1 HTTP Daemon…Registering device failed

Configure eth0…initial boot…No DHCP…failed

0.0.0.0 ready

If someone know what is the problem let me know please.
