各位高手！我刚接触嵌入式不久，遇到了很多问题，现在正在做S3C2410的根文件系统，可是怎么试都不能顺利启动挂载。我的内核是2.6.14，基本步骤如下（参考《Linux系统移植》）：<br /><br />1.创建根文件系统的基本目录结构。（包含bin&nbsp;dev&nbsp;etc&nbsp;lib&nbsp;proc&nbsp;sbin&nbsp;sys&nbsp;usr&nbsp;等目录）<br />2.配置、编译和安装Busybox-1.1.3<br />3.修改和创建必要的文件。（增加为SHELL导入全局变量的文件/etc/profile、增加初始化文件、增加初始化脚本、创建inetd.conf配置文件等）<br />4.建立根文件系统包（利用cramfs-1.1制作cramfs包）<br />5.将制作好的my_rootfs.cramfs烧写到flash中。<br /><br />结果启动时总是显示:<br />VIVI&nbsp;version&nbsp;0.1.4&nbsp;(root@localhost.localdomain)&nbsp;(gcc&nbsp;version&nbsp;2.95.3&nbsp;20010315&nbsp;(re<br
