移植Linux内核到S3C2410开发板的问题

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

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!
