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

[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

为能够是usb wifi能够正常访问网络，还需一些应用软件：iwconfig iwlist 等

Fig1.4 usb wifi在/dev/目录下存在的设备节点1-1
3.wifi应用软件的编译及使用
3.1
同上在解压出来的驱动包有wire tools具体如果应用也有相关文档说明，进入解压后目录找到Makefile文件，同样需要修改一些编译选项
[root@localhost wireless_tools.30.rtl]# pwd
/home/s3c6410/s3c6410/driver/RTL8188C_8192C_8192D_USB_linux_v3.4.2_3727.20120404/wireless_tools/wireless_tools.30.rtl
[root@localhost wireless_tools.30.rtl]#

Fig1.5 修改编译条件

Fig1.6成功编译后将获得绿色显示的工具
图1.6工具在本次中未能够使用到此处略去,日后需要将补上…

3.2
        进入以下目录，同样需修改Makefile文件进行交叉编译得到工具wpa_supplicant
[root@localhost wpa_supplicant]# pwd
/home/s3c6410/s3c6410/driver/RTL8188C_8192C_8192D_USB_linux_v3.4.2_3727.20120404/wpa_supplicant_hostapd/wpa_supplicant_hostapd-0.8/wpa_supplicant
[root@localhost wpa_supplicant]#

Fig1.7 将CC改为arm-linux-gcc
在该目录执行make后将得到下图绿色显示的工具，为能够正常运行，先静态配置wlan0的ip（动态方式后续更新）








Fig1.8 成功编译wpa_supplicant 目录工具
配置wlan0 ip地址：

通过ifconfig后比先前看到的多出wlan0，可见目前已经将wlan0激活。但仍需要要一些应以偶那个设置方能访问网络。
在etc目录下创建wpa_supplicant.conf配置文件，文件内容如下：
# WPA-PSK/TKIP
ctrl_interface=/var/run/wpa_supplicant
network={
        ssid="XTRAMUS"
        scan_ssid=1
        key_mgmt=WPA-EAP WPA-PSK IEEE8021X NONE
        pairwise=TKIP CCMP
        group=CCMP TKIP WEP104 WEP40
        psk="AABBCCDDEF"
}
ssid一个无线局域网分为几个需要不同身份验证的子网络，每一个子网络都需要独立的身份验证，只有通过身份验证的用户才可以进入相应的子网络，防止未被授权的用户进入本网络.
key_mgmt：加密方式 wpa等
psk 我理解成密钥，如理解错在更新

配置文件有了，接下来执行
[root@Xtramus6410 /opt]# wpa_supplicant -Dwext -iwlan0 -c /etc/wpa_supplicant.conf -dd &
结果出来一长串的信息，以后慢慢了解！

大功告成，通过usb wifi可以正常访问外网
题外话：因为ping的是域名地址www.baidu.com需要进行DNS转化因此在etc目录下需要有个resov.conf的文件，文件内容如下：
nameserver 192.168.1.1
nameserver 8.8.8.8
