 [请教] linux2.6.22 CRAMFS 启动后 ,无控制台。



2. 现在安装说明http://blog.chinaunix.net/u2/69947/showart_1101367.html 制作了cramfs文件系统,驱动时没有错误了,但是 不能进入控制台

网上查看了原因,说是无console, 我已经建过了:

哦,可能是我的内核不支持 dev_fs ; 2.6.22的怎么添加? 只需要修改fs/Kconfig吗? 对应的源码是否需要补充?

不要尝试在2.6的内核上加入已经遗弃很久的devfs,正确的做法是用udev或者busybox的mdev

在dev下面是否有console这个节点?
