开发板挂载U盘

1、插上U盘，串口终端显示：

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

2、fdisk -l

没有任何输出，有可能是U盘的驱动没有安装上

3、配置内核的USB部分

-> Device Drivers 

-> USB support

<*>  USB Mass Storage support

-> Device Drivers

<*> SCSI device support 

配置好以后，make ,重新做好 uImage，替换原来的内核

4、用替换的内核，完全启动后，插入U盘，串口终端显示

usb 1-1: new full speed USB device using s3c2410-ohci and address 2
usb 1-1: configuration #1 chosen from 1 choice
scsi0 : SCSI emulation for USB Mass Storage devices
scsi 0:0:0:0: Direct-Access     Teclast  CoolFlash        0.00 PQ: 0 ANSI: 2
sd 0:0:0:0: [sda] 3948544 512-byte hardware sectors (2022 MB)
sd 0:0:0:0: [sda] Write Protect is off
sd 0:0:0:0: [sda] Assuming drive cache: write through
sd 0:0:0:0: [sda] 3948544 512-byte hardware sectors (2022 MB)
sd 0:0:0:0: [sda] Write Protect is off
sd 0:0:0:0: [sda] Assuming drive cache: write through
 sda: unknown partition table
sd 0:0:0:0: [sda] Attached SCSI removable disk

注意上面的红色部分，那是因为U盘还没有被分区，重新在linux下面分区，使用

fdisk /dev/sdb  当然了，看具体情况而定。我是按照这个网页来进行操作的，

5、将分区后的U盘，重新插上，显示如下信息

 

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
scsi 1:0:0:0: Direct-Access     Teclast  CoolFlash        0.00 PQ: 0 ANSI: 2
sd 1:0:0:0: [sda] 3948544 512-byte hardware sectors (2022 MB)
sd 1:0:0:0: [sda] Write Protect is off
sd 1:0:0:0: [sda] Assuming drive cache: write through
sd 1:0:0:0: [sda] 3948544 512-byte hardware sectors (2022 MB)
sd 1:0:0:0: [sda] Write Protect is off
sd 1:0:0:0: [sda] Assuming drive cache: write through
sda: sda1
sd 1:0:0:0: [sda] Attached SCSI removable disk

6、注意上面的蓝色字体，我们用

mount -t vfat /dev/sda1 /mnt

得到的显示信息为：

# mount -t vfat /dev/sda1 /mnt/
Unable to load NLS charset cp437
FAT: codepage cp437 not found
mount: mounting /dev/sda1 on /mnt/ failed: Invalid argument

7、重新配置内核

File systems
               ->  Native language support

                     <*>   Codepage 437 (United States, Canada) 

File systems
                -> Native language support

                     <*>   NLS ISO 8859-1  (Latin 1; Western European Languages)  

8、重新 make,将重新做好的uImage 替换原来的内核

mount -t vfat /dev/sda1 /mnt 就可以成功挂载。
