串口问题

按照setp12中修改完serial之后，串口仍然是can't open /dev/tq2440_serial0:no such file or director 应该如何解决？

kernel panic -not syncing: attempted to kill init

论坛上有这样的帖，你的rcS脚本没有运行成功，你先搜一下。

首先解决你的rcS脚本问题，再来看串口吧。

谢谢楼上的朋友，试试看。

修改串口后没有了这个设备，证明修改错误了嘛！
没有熟练的时候，多多对比来开发哟

对照移植步骤查了好几遍。就是没找到错误在哪。用我编译的内核和天嵌的文件系统能跑起来，可能是我的文件系统有错误

一个一个解决吧。把你的rcS 初始化执行脚本弄好了看看。
