问题:


内核配置时使用smdk2410的默认配置. U盘不能挂载!


插拔U盘提示信息为:


$ usb 1-1: USB disconnect, address 2


usb 1-1: new full speed USB device using s3c2410-ohci and address 3


usb 1-1: configuration #1 chosen from 1 choice


办法:


重新配置内核, 启用SCSI device support,SCSI相关模块最好编译进内核,不要以module形式编译。


再次插上U盘提示信息为:


插上U盘后,显示:


usb 1-1: new full speed USB device using s3c2410-ohci and address 3


usb 1-1: configuration #1 chosen from 1 choice


scsi1 : SCSI emulation for USB Mass Storage devices

sda: p1 exceeds device capacity

U盘的设备名称为sda1,执行命令挂载:


#mount -t vfat sda1 /mnt


提示错误信息:


Unable to load NLS charset cp437


FAT: codepage cp437 not found


mount: mounting sda1 on /mnt failed: Invalid argument


原因是内核缺少cp437字符集。


重新配置内核,在filesystems-->native language support-> 中选择Codepage 437和其他的一些常用的字符集。


再次执行命令挂载:


#mount -t vfat sda1 /mnt


挂载成功,无任何错误信息输出!
