uClinux 编译后不能启动，求助。

johninfo

当run之后，系统显示
Starting programe: /home/uClinux-dist/linux-2.4.x/linux
就不动了。

停止运行后系统显示
setup_processor() at setup.c:145
系统在while(1);中停止。

list 察看代码如下：
if(list>= &__proc_info_end){
       printk("CPU configuration botch(ID %08x),unable"
                  "to continue.\n",processor_id);
       while(1);
}


会是设么原因。

ksh

没有找到对应的processor_id,你用的是什么开发板？

我也出现这个问题，望兄弟们帮把忙

解决了这个问题
用以下skyeye.conf:

mach: at91

感觉是你的文件系统的位置不对，你可以尝试调试一下uclinux，进一步确定问题所在。
