不明白别人的就算不行也没有最后的4行，我的却有，不明白啊，各位大哥大姐帮帮哦啊

看起来yaffs文件系统已经挂载成功了，问题是/initrc无法执行。文件系统也是用4.3.2的交叉编译器编译的？

我直接下的yaffs2打的补丁，应该可以用吧？
我想就算不能用的话，也不应该有最后那4行,对么？？

最后四行是因为init进程退出引起的，任何原因导致init进程退出都会出现。
你还没有回答我的问题，对么??

今天我又做了个文件系统，用的也是4.3.2编译的，这个文件系统没有问题，换个内核镜像就正常启动了，但用这个内核还是不行，bootloader传递的命令行也是正确的，不明白啊

自己小顶一下哈

这是啥意思？？
你的kernel + 做的文件系统==不行
换个kernel镜像+做的文件系统==OK？？

我分析，一下不就是BUSYBOX 好像与kernel没关系，，还是rootfs的问题吧。。。请高人解答哦。。

我也在mini2440上遇到了同样的问题，期待高手指导

我也碰到这个问题了，烧到NAND flash里的是友善提供的yaffs2文件系统映像，后来尝试了用nfs挂载友善的root_qtopia，也不成功。

从官网上下了一个Linux2.6.34版本的内核，由于已经加入了对mini2440的支持，加入对yaffs2的支持后，我自己就编译了一个内核，在配置内核时，选择了nfs挂载根文件系统的支持，用U-boot通过nfs下载内核启动后却挂载不成功，详细的信息如下：

然后我又换友善的内核，可以成功通过nfs挂载根文件系统，详细的信息如下：

主机的nfs服务是成功开启的，请各路大侠帮忙分析下有可能是什么原因。

nfs挂载的问题解决了，要打补丁。
