缺少  please press Enter to acktivate console  这句话进入文件目录，can't open /dev/        “  tq2440_serial0: No such file or director ”一直在这一句循环。大家帮我看看谢谢了。

如果是使用的自己移植的内核，在Linux移植手册中12.1章节讲了串口设备名要改为tq2440_serial，你没有修改它。或者你修改文件系统中的所有和tq2440_serial0相关的字样为你设定的串口设备名。

2# 亚瑟王 ，太感谢了，都怪自己没看后面的步骤，确实是串口配出了问题。现在烧写进去，可以在控制台操作了。统可以正常启动了，但又出了个问题。情况是刚刚启动不久（一般十几秒），系统就自动重启了了。  还有这样的信息：
mount: can't find devpts/dev/pts in /etc/fstab
hostname: can't open '/etc/sysconfig/HOSTNEME': No such file or directory

可是这些文件我在做成系统的过程中并没有遗忘啊，都按照步骤加载了。系我有点不明白，亲指点一下。在下不胜感激。

1、过段时间重启是因为你的内核配置时选择了看门狗，而文件系统中又没有喂狗程序导致的。
2、剩下两个错误是因为你的文件系统缺少组件导致的，建议你再看一下天嵌科技的Linux移植手册。

4# 亚瑟王 关于“重复发帖”的情况是我当时有些着急了，确实不好意思。这里还有一个不情之请，能不能把你的文件系统源码“root_2.6.30.4”给我发一份。我的邮箱 tell_who@sina.com  如有麻烦请多多见谅。

文件系统的原始文件在天嵌科技的光盘中：“Linux资源\Linux源码包\2.6.30.4\root_qtopia_2.2.0_2.6.30.4_20091216.tar.bz2”

6# 亚瑟王 多谢了！我好好看看源文件。

6# 亚瑟王
您好，我这里也出现同样的问题，不过我烧上你们提供的4.5版的root后可以正常启动，然后内核里面也有qt2440_serial0,应该是我root弄的有问题，能否提供一下你们的版本的包？谢谢。我的邮箱：602559817@qq.com

不懂你这个“你们的版本的包”是什么意思。

9# 亚瑟王
不好意思，表述问题，就是你们的文件系统，我这里只有用mkyaffsimage_2生成的，我想要原始的，我想看看我做的文件系统为什么会出现这个错误。谢谢

你的开发板的Nand是256MB的呢？还是64MB的？256MB的是使用mkyaffs2image，64MB的是mkyaffsimage_2。

11# 亚瑟王
您好，我的是64M的，我是用mkyaffisimage_2的。

原始的文件系统包在光盘中的，在6楼我已经回答了。
