关于测试U盘实验

插入U盘后,超级终端没有显示U盘的设备文件号,象<开发板使用手册V2.0>那样的
该怎么挂载??

看看 mnt/udisk目录下有没有你U盘的内容呢？
有，就可以访问了，我是有的。

没有
mnt下面有udisk和sd两个文件夹,但里面没有内容

挂载失败

Partition table entries are not in disk order
[root@EmbedSky /]# mount /dev/sda /mnt/udisk
[root@EmbedSky /]# cd /mnt/udisk
[root@EmbedSky udisk]# ls
sss.txt
[root@EmbedSky udisk]#

以上,我用mount /dev/sda /mnt/udisk
就可以挂载成功了,好象和使用手册说的方法不同,
高手可以告诉我有什么区别吗??

楼主没有仔细看手册哦，手册里面讲了的，对于只出现sda而不出现sda1的需要重新配置自动挂载脚本或手动挂载U盘哦。
