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
