[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
