Linux 2.6.24.4移植到S3C2410(nano2410)之：USB

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

major minor  #blocks  name

 

  31     0       1024 mtdblock0

  31     1       3072 mtdblock1

  31     2      40960 mtdblock2

  31     3      20480 mtdblock3

 

root@kevin /dev

$ ls u*

urandom         usbdev1.1_ep00  usbdev1.2       usbdev1.2_ep01

usbdev1.1       usbdev1.1_ep81  usbdev1.2_ep00  usbdev1.2_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

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

用dmesg查看信息:

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.

root@kevin /

$ ls /mnt/usb

OK,　U盘挂载成功了~~~
