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/

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

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

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！
