v1.0b001 2012-6-18 初始版本，介绍在嵌入式linux方面如何移植usb wifi相关
嵌入式linux usb wifi移植参考文档
■ 硬件平台：realARM 6410
■ 操作系统：fedora kernel 2.6.33.3-85.fc13.i686.PAE
■ 交叉编译器：arm-none-linux-gnueabi gcc version 4.3.2
■ WIFI模组：磊科NW336 芯片 realtek 8188cus
【前提 linux系统可以在板子上正常运行】
1. 调试步骤
移植usb wifi首先确定板子上的USB Host功能正常运行，进入内核配置界面，如下图进行配置。
Fig1.0linux kernel 2.6.36打开USB HOST界面
从新编译内核后启动开发板，并插入U盘后，通过mount命令进行U盘加载
Mount /dev/sdb1 /mnt/
Cd /mnt/
Ls
得到下图Fig1.1结果
Fig 1.1 mount U盘成功
2.下载磊科 USB WIFI 对应芯片驱动realtek8188cus，从官网下载linux驱动
http://www.realtek.com/downloads ... oads=true#RTL8192CU
拷贝并解压得到以下目录

[root@localhost RTL8188C_8192C_8192D_USB_linux_v3.4.2_3727.20120404]# cd driver/
进入driver目录并解压rtl8188C_8192C_8192D_usb_linux_v3.4.2_3727.20120404.tar.gz文件
在改目录下找到文件Makefile并作出相应的修改，因为默认情况下是PC平台x86结构的
/home/s3c6410/s3c6410/driver/RTL8188C_8192C_8192D_USB_linux_v3.4.2_3727.20120404/driver/rtl8188C_8192C_8192D_usb_linux_v3.4.2_3727.20120404
Fig 1.2 将s3c6410平台从n改为y
Fig1.3根据自身linux开发环境做修改
在driver目录修改完Makefile后，执行make指令。不出意外将顺利完成编译必应从2.6.34内核到2.6.36内核驱动中涉及到的结构体变动比较小！如果内核跨度大的有可能出现结构体不一致而不得不修改源码。
[root@localhost rtl8188C_8192C_8192D_usb_linux_v3.4.2_3727.20120404]# ls
8192cu.ko 8192cu.mod.o autoconf_rtl8192c_usb_linux.h clean hal include make_drv modules.order os_dep
8192cu.mod.c 8192cu.o autoconf_rtl8192d_usb_linux.h core ifcfg-wlan0 Kconfig Makefile Module.symvers wlan0dhcp
[root@localhost rtl8188C_8192C_8192D_usb_linux_v3.4.2_3727.20120404]#
其中8192cu.ko 将是我们需要的驱动模块文件

v1.0b001 2012-6-18 初始版本，介绍在嵌入式linux方面如何移植usb wifi相关
嵌入式linux usb wifi移植参考文档
■ 硬件平台：realARM 6410
■ 操作系统：fedora kernel 2.6.33.3-85.fc13.i686.PAE
■ 交叉编译器：arm-none-linux-gnueabi gcc version 4.3.2
■ WIFI模组：磊科NW336 芯片 realtek 8188cus
【前提 linux系统可以在板子上正常运行】
1. 调试步骤
移植usb wifi首先确定板子上的USB Host功能正常运行，进入内核配置界面，如下图进行配置。
Fig1.0linux kernel 2.6.36打开USB HOST界面
从新编译内核后启动开发板，并插入U盘后，通过mount命令进行U盘加载
Mount /dev/sdb1 /mnt/
Cd /mnt/
Ls
得到下图Fig1.1结果
Fig 1.1 mount U盘成功
2.下载磊科 USB WIFI 对应芯片驱动realtek8188cus，从官网下载linux驱动
http://www.realtek.com/downloads ... oads=true#RTL8192CU
拷贝并解压得到以下目录

[root@localhost RTL8188C_8192C_8192D_USB_linux_v3.4.2_3727.20120404]# cd driver/
进入driver目录并解压rtl8188C_8192C_8192D_usb_linux_v3.4.2_3727.20120404.tar.gz文件
在改目录下找到文件Makefile并作出相应的修改，因为默认情况下是PC平台x86结构的
/home/s3c6410/s3c6410/driver/RTL8188C_8192C_8192D_USB_linux_v3.4.2_3727.20120404/driver/rtl8188C_8192C_8192D_usb_linux_v3.4.2_3727.20120404
Fig 1.2 将s3c6410平台从n改为y
Fig1.3根据自身linux开发环境做修改
在driver目录修改完Makefile后，执行make指令。不出意外将顺利完成编译必应从2.6.34内核到2.6.36内核驱动中涉及到的结构体变动比较小！如果内核跨度大的有可能出现结构体不一致而不得不修改源码。
[root@localhost rtl8188C_8192C_8192D_usb_linux_v3.4.2_3727.20120404]# ls
8192cu.ko 8192cu.mod.o autoconf_rtl8192c_usb_linux.h clean hal include make_drv modules.order os_dep
8192cu.mod.c 8192cu.o autoconf_rtl8192d_usb_linux.h core ifcfg-wlan0 Kconfig Makefile Module.symvers wlan0dhcp
[root@localhost rtl8188C_8192C_8192D_usb_linux_v3.4.2_3727.20120404]#
其中8192cu.ko 将是我们需要的驱动模块文件

启动的时候顺利识别到usb wifi，说明USB HOST没问题，接着将加载驱动模块不管用何种方式（NFS，or ftp tftp均可）本文档采用的是tftp将模块驱动down到板子/opt/目录上
