[国嵌攻略][163][linux-usb软件系统架构]

软件系统架构

1.主机端软件架构

USB设备驱动->USB核心->USB主控制器驱动->USB主控制器

2.设备端软件架构

Gadget驱动->Gadget API->UDC驱动->USB控制器

 

MassStrorage驱动体验(host 接口)

可以让主机挂载大容量存储器

1.主控器驱动配置

make menuconfig ARCH=arm

device drivers->usb support->[*]support for host-side usb-><*>ohci hcd support

2.配置设备驱动

device drivers->usb support->[*]support for host-side usb->

usb mass storage support

3.配置热插拔

general setup->[*]configure standard kernel features(for small systems)

->[*]support for hot-pluggable devices

4.配置块设备

device drivers->[*]block devices-><*>low performance usb block driver

device drivers->scsi device support-><*>scsi device support

device drivers->scsi device support-><*>scsi disk suppport

device drivers->scsi device support-><*>scsi generic support

5.配置文件系统

file systems->dos/fat/nt filesystems-><*>msdos fs support

file systems->dos/fat/nt filesystems-><*>vfat(windows-95)fs support

file systems->dos/fat/nt filesystems->(936)default codepage for fat

file systems->dos/fat/nt filesystems->(cp936)default iocharset for fat

file systems->partition types->[*]advance partition selection->

[*]pc bios(msdos partition tables) support

file systems->native language support->

<*>simplified chinese charset(cp936,gb2312)

file systems->native language support-><*>NLS UTF8

5.编译内核

make uImage ARCH=arm CROSS_COMPILE=arm-linux-

6.挂载块设备

mount /dev/uba /mnt

 

RNDIS驱动体验(salve 接口)

可以使USB端口模拟成网卡使用

1.配置控制器驱动

make menuconfig ARCH=arm

device drivers->usb support-><*>usb gadget support->

usb peripheral controller(s3c2410 usb device controller)

2.配置gadget驱动

device drivers->usb support-><*>usb gadget support->[M]usb gadget drivers

device drivers->usb support-><*>usb gadget support->

[M]ethernet gadget(with cdc ethernet support)->[*]rndis support

3.编译内核

make uImage ARCH=arm CROSS_COMPILE=arm-linux-

4.编译模块

make modules ARCH=arm CROSS_COMPILE=arm-linux-

cp drivers/usb/gadget/g_ether.ko .../rootfs

5.安装模块

insmod g_ether.ko

6.启动usb网卡

ifconfig usb0 192.168.30.1

7.安装usb网卡驱动

打开Windows设备管理器->更新驱动程序软件->从计算机的设备驱动程序表中选择->网络适配器->Microsoft Corporation->Remote NDIS Compatible Device

8.设置usb网卡地址

9.测试usb网卡

ping 192.168.30.1
