linux-2.6.35内核移植—USB驱动的添加

【实验目的】

在FS2410开发板上进行linux-2.6.22.6内核的移植，这个部分完成USB设备驱动的添加，完成相应的功能。

【实验环境】

1、 Ubuntu 10.10发行版

2、 u-boot-2010.03

3、 FS2410平台

4、 交叉编译器 arm-none-linux-gnueabi-gcc-4.3.2

【实验步骤】

1、 配置内核

Device Drivers --->

SCSI device support --->

<*> SCSI disk support

<*> SCSI generic support

<*> SCSI media changer support

[*] USB support --->

<*> USB Mass Storage support

File systems --->

-*- Native language support --->

<*> Codepage 437 (United States, Canada)

<*> Simplified Chinese charset (CP936, GB2312)

<*> ASCII (United States)

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

2、 编译内核

$ make zImage

3、 拷贝内核镜像到tftpboot目录下

$ cp arch/arm/boot/zImage /tftpboot

4、 重启系统后插入U盘

显示如下内容：

usb 1-1: new full speed USB device using s3c2410-ohci and address2

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

scsi0 : SCSI emulation for USB Mass Storage devices

scsi 0:0:0:0: Direct-Access Netac OnlyDisk 1.00 PQ: 0 ANSI: 2

sd 0:0:0:0: [sda] 2039808 512-byte hardware sectors (1044 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] 2039808 512-byte hardware sectors (1044 MB)

sd 0:0:0:0: [sda] Write Protect is off

sd 0:0:0:0: [sda] Assuming drive cache: write through

sda: sda1

sd 0:0:0:0: [sda] Attached SCSI removable disk

sd 0:0:0:0: Attached scsi generic sg0 type 0

这说明发现了一个usb设备设备名为sda，分区sda1

5、 创建设备节点

# mknod /dev/sda1 b 8 1

6、 挂载U盘

# mount -t vfat /dev/sda1 /mnt

7、 查看U盘内容

# ls /mnt
