我的带有busybox的armlinux终于成功了!
虽然遇到的问题都是小问题,但是对于我这样的新手还是挺郁闷的.不过现在弄出来了,感觉还是很爽的:) (linux-2.4.18.tar.bz2+patch-2.4.18-rmk7+busybox-1.01.tar.bz2)
现在太忙,我要是什么时候有时间就把过程整理给大家:)

dev home linuxrc mnt sbin var 热烈关注，我也在学这方面的知识 希望能够把你的成功过程记录下来,让更多的人知道. 我会加为精华! 我用busybox做的image为什么不行呢？使用的同样的armlinux版本。用斑竹贴出来的image是可以正常跑到shell的。

最初我是用arm-linux-gcc编译busybox-1.01，执行/sbin/init时停掉了。后来改用了uClibc-gcc(一次选支持浮点，有FPU；另一次选不支持浮点)编译busybox，如上报非法指令。

大虾们是否能给些指点。或者诸位的不是使用busybox的工具包的话，那用的是怎么生成的呢？ 我现在使用arm-linux-gcc编译busybox1.2.2.1就在init.c的时候报错
说file truncated
我无言。。。不知为何 不知道是不是因为工具版本太低？
