Kernel疑问

求教大家，我照着天嵌《Linux移植STEP BY STEP》手册操作，完成了STEP 1-12，当把制作完成的kernel和文件系统烧录到开发板时，发现依旧无法进入console。自己也试了好几次了，都没有成功。超级终端上的回显信息如下：

open device leds: No such file or directory

wuweidong 发表于 2012-4-15 08:57
楼主还有信息没贴出来

请问版主，到了open device leds: No such file or directory 这里就停住了，还需要哪些信息呢？

wuweidong 发表于 2012-4-17 21:48
open device leds: No such file or directory如果卡住了，
可以修改脚本不要运行led应用程序先

请问，这应该是内核中的哪个脚本文件呢？
