买我们TQ的板子已经快两个月了,一直都是自己在研究,最近这段时间频频遇见难题。
  这几天移植内核和根文件系统,内核已经能支持yaffs2   但是启动后按回车却出现这样的问题,求大家帮帮忙~~   下面是我的串口打印的信息:

按了回车键之后光标停在root 左边不能显示目录。
下面是我的根文件系统/etc  下几个文件的代码

请各位大侠帮一下, 我费尽心思还是找不到原因,我用光盘的内核下载到开发板,然后加载我的根文件系统也是不行的,证明是我的根文件系统这一部分有问题。  请各路英雄赐教!!!   不胜感激~~!!!!!!:Q

补充:我再次尝试   按下回车后   我输入ls    居然可以出现根文件   我把串口打印出来

这里的问题是为什么按下回车后  会出现哪些错误    求指点!~~

内核中已经启动了看门狗,而你的文件系统中没有启动看门狗的喂狗程序,所以会重启。
你烧写光盘中的文件系统+你的内核然后试一下。

我直接把光盘的/etc  目录copy 到我的文件系统就解决了。应该是我的/etc 文件出现乱码导致。  谢谢版主!!
