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~~~
