网卡移植

我使用的是2.24.6的内核，参照给的教材移植网卡可是始终不能成功，在uboot中进行nfs挂载时出现这样的信息：

是网卡移植出现了问题吗？

是的，网卡驱动有问题，建议你从yaffs启动，然后通过ping命令ping PC或者PC ping开发板来测试网络是否OK。

ping网络是ping不通的
用ifconfig指令显示的是
ifconfig eth0 hw ether 10:23:45:67:89:ab
ifconfig: SIOCSIFADDR: No such device
ifconfig eth0 192.168.1.6 netmask 255.255.255.0 up
route: SIOCADDRT: Network is unreachable
add default gw 192.168.1.2
网卡我已经移植了
串口打印时有这个显示

不知道系统是哪里出错了，或者是还缺少什么，请指教

ifconfig: SIOCSIFADDR: No such device
这个信息表明实际上的网卡加载没有成功，检查一下你的dm9000的驱动吧。
