希望能尽快得到解决

不能打开网卡，因为内核中的网卡没有设置mac值。
dm9000 Ethernet Driver
eth%d: Invalid ethernet MAC address.  Please set using ifconfig
eth0: dm9000 at c485e000,c4860004 IRQ 51 MAC: ff:ff:ff:ff:ff:ff
解决方法：修改Linux内核源码drivers/net/dm9000.c文件，对网卡添加上一个mac值即可解决。

能提供一下源码吗？

你看一下http://bbs.embedsky.net/viewthre ... &extra=page%3D2这个帖子的答案。
