Linux 2.6.24.4移植到S3C2410(nano2410)之：USB

【平台信息】

目标板(Nano2410)------------------------

CPU: S3C2410X

SDRAM:HY57V561620(32MB)

FLASH: K9F1208(64MB)

NET: CS8900

HOST---------------------------------------

Linux Realse Version:Fecora Cor 8 (FC8)

CrossCompiler:gcc-4.1.1/glibc-2.3.2

问题的提出:

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

查看partitions下的分区信息,没有出现USB设备

root@kevin /proc

$ cat partitions

usbdev1.1usbdev1.1_ep81usbdev1.2_ep00usbdev1.2_ep82

解决方法:

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.

插上U盘后,显示:

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

u盘设备名为sda1.

$ mount -t vfat sda1 /mnt

Unable to load NLS charset cp437

FAT: codepage cp437 not found

mount: mounting sda1 on /mnt failed: Invalid argument

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.

重新mount

root@kevin /

$ mount -t vfat /dev/sda1 /mnt/usb

查看usb目录下被挂载的文件.
