 mini2440不识别U盘

刚拿到手的2440,开机后插上U盘没反应,U盘是8G的FAT32的,请问怎样可以识别并打开U盘里的文件?

你的U盘不包含一个合法的分区表,因此友善之臂的root_qtopia文件系统镜像没法自动挂载它。理由看这里

你可以尝试在命令行上手动挂载U盘:
#mount /dev/sda /udisk

我不清楚默认的文件系统镜像里有没有PDF的阅读器,如果有的话,用上面的命令挂载U盘后,让阅读器打开/udisk目录应该就能找到U盘上保存的PDF文件了。视频播放器也是一样的。

如果没有/dev/sda, 用
#mknod /dev/sda b 8 0

如果没有/udisk, 用
#mkdir /udisk
