在尝试挂载S3C2440开发板上的U盘时遇到"No such file or directory"错误。通过查看设备和分区，发现sda1设备节点未在/dev目录下。解决方法是手动创建设备节点sda1，使用mknod命令，然后成功挂载并能查看到U盘内的文件。

今天学习了下S3C2440的U盘挂载，发现No such file or directory问题，

挂载方法操作如下:

1,开发板插入U盘，串口输出如下：

# usb 1-1: new full speed USB device using s3c2410-ohci and address 2

usb 1-1: configuration #1 chosen from 1 choice
scsi0 : SCSI emulation for USB Mass Storage devices

2，创建挂载目录

mkdir /mnt/udisk
