开发板挂载U盘
(2012-02-21 21:04)
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
- # 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。
