当我ping我的主机IP时，提示：ping：sendto：network   is  unreachable
我用板子自带的img文件试过，网卡正常
请教高手这怎么回事啊？

是不是，我的文件系统的配置文件的IP需要改啊

试试先设置IP再Ping：
ifconfig eth0 192.168.1.199 up

进入控制台后，
Please press Enter to activate this console.
[mini2440]#ifconfig eth0 192.168.0.2 up
ifconfig: SIOCSIFFLAGS: Cannot assign requested address
[mini2440]#ifconfig

这里好像没有eth0？但是我的启动信息明明显示了：
eth0: dm9000e at c486e300,c4872304 IRQ 51 MAC: 08:08:11:18:12:27 (chip)
