在skyeye下仿真linux 2.6.24,busybox为1.13.3,gcc编译器是从"友善之臂"的网站上下的,版本为4.3.2,skyeye提供的编译环境arm-2008-11-24.iso也试过,出现同样的问题。
我尝试将skyeye-testsuite-1.2.5中s3c2410x-2.6.14的文件系统的内容复制到我自己做的文件系统中,结果文件系统可以正常启动了。
可以肯定是busybox编译的问题。
怀疑是mdev原因,但可能性不大,因为skyeye-testsuite-1.2.5中s3c2410x-2.6.14的文件系统并不支持mdev,文件系统还是可以启动的,网上提到的要支持tmpfs、sysfs、Kernel Features、Floating point emulation等相关项也已经选择上的,问题依旧。
此外,我还尝试过用qemu仿真过自己做的文件系统,结果动态编译的可以正常运行,而静态编译的则提示找不到设备,skyeye-testsuite-1.2.5中s3c2410x-2.6.14的文件系统是静态编译的,在qemu下也是可以运行的。

busybox编译到最后,无论是动态编译还是静态编译都会揭示:
Trying libraries: crypt m
Library crypt is needed
Library m is needed
Final link with: crypt m
我的理解静态编译时不应该出现,不知道是什么原因?

现可确定是busybox的问题,但不知道问题在哪里,请高人指点。

实验中的skyeye.conf内容
#skyeye config file sample

#lcd:type=s3c2410x,mod=gtk
load_addr:base=0x30000000, mask=0xFFFFFF

如果实在解决不了,请兄弟们传我一个已经编译好的busybox(带mdev功能),静态或动态编译的都行,谢谢!!!

我也是同样的问题静态动态编译都不行
