busybox问题

在制作根文件系统时，如果busybox配置项“Build BusyBox as a static binary(no shared libs)”不选中，则编译安装后生成的跟文件系统烧写到nand后，启动失败：
Failed to execute /init.  Attempting defaults...
Kernel panic - not syncing: No init found.  Try passing init= option to kernel. See Linux Documentation/init.txt for guidance.

而如果选中“Build BusyBox as a static binary(no shared libs)”则没有问题，但应用程序无法运行（hello是一个简单的打印程序，打印“hello word”而已）：
-/bin/sh: ./hello: not found
已经拷贝glibc库到/lib

请问有谁遇到过类似问题吗？
