急问:arm板上linux系统起来进不了命令提示符

suntek-video

请问各位大侠:arm板上linux系统起来进不了命令提示符,一般是由什么原因导致的

bitmilong

樓主確定linux系統已經啟動了?

suntek-video

是的

然后下面就没了,没有显示:

Enter 'help' for a list of built-in commands.


还有同一个系统下到两块不同的板子上,一个有命令提示符,一个没,板子也是同一批次出来的

可以将busybox上的inittab、rcS等配置文件贴出来吗？

恩。最好在配置文件里用echo打印一些信息
你的linuxrc是怎样配置的？用busybox的话，应该会首先运行这个脚本

suntek-video

这个系统现在是在有的板子上出命令提示符,而有的板子上没有命令提示符,这批板子将近有40%没有命令提示符,还有用的是uclinux没找到对应的linuxrc,只有一个rc文件

suntek-video

首先感谢二位的帮忙,经检查,确定是由于rtc的原因造成的
