（已解决）skyeye上的armlinux的启动init出错

truesy

我用的开发环境：redhat9，armlinux2.4.18-rmk7+bysybox1.01+arm-linux-
我建了一个ext2的ram文件initrd，然后建立的相应的目录，内核编译和busybox编译通过，但是启动armlinux的时候，提示找不到init。启动信息如下：

我想请教各位大虾，armlinux启动时的init是不是用的是busybox下面的那个init？如果是的话，为什么找不到呢？我的busybox的init是正确安装在/sbin/下面的，而且也是正确链到busybox上的。

紧急求助阿！！！
谢谢！！！

ksh

replace :
Kernel command line: root=/dev/ram init=/linuxrc console=ttyAM0,9600
to :
Kernel command line: root=/dev/ram console=ttyAM0,9600
then try again

斑竹，我试过了。还是一样的错误。不知道有哪位用：
Kernel command line: root=/dev/ram console=ttyAM0,9600 成功过？我怀疑busybox本身的init有问题，不能用。
现在这个问题我已经解决了，修改如下：
Kernel command line: root=/root/initrd console=ttyAM0,9600
即：用我的/文件系统来运行Init，成功进入busybox。用initrd来运行Init也是busybox的配置选项。
注：initrd是我建的ext2文件系统的img文件。
遗留问题：  怎么才能让busybox的/sbin/init可以正常运行？？？？？？？？？？
还请指教！！！！！

现在我已成功在skyeye下运行了armlinux+busybox，这期间我也遇到了很多问题。下一步准备整理一下自己的资料，希望能对面临同样问题的一些参考！
另外，我发点牢骚：《源码开放的嵌入式系统软件分析与实践》那本书，本身其实还是不错的。不过的却有些零乱，比如，我在编译armlinux的时候，光看那一节的介绍根本编译不成功，希望斑竹能够对armlinux ,uc,uII，busybox的编译和配置，在网上能够集中详细介绍一下。这样大家就能快速的建立起这个开发环境。。。。我的一点点感想！
