Hi all, Thanks for your care!A few days latter I met a trouble that one of roach2 board doesn't work stable.I try to re-setup it through FTDI usb.Well ,the other problem comes. When I setup it with minicom ,it shows the message like this: ENET Speed is 100 Mbps - FULL duplex connection (EMAC0) BOOTP broadcast 1 *** Unhandled DHCP Option in OFFER/ACK: 28 *** Unhandled DHCP Option in OFFER/ACK: 28 DHCP client bound to address 192.168.100.5 Using ppc_4xx_eth0 device TFTP from server 192.168.100.100; our IP address is 192.168.100.5 Filename 'uImage'. Load address: 0x4000000 Loading: T T T T T T T T T T Retry count exceeded; starting again It tells the loading problem,and star again and again . Has anyone met this before? Best Regards! peter
