http://blog.csdn.net/pb09013037/article/details/37760405

1、 内核配置

硬件上将USB的ID引脚接地

内核将DM365的USB配置成USB HOST工作模式

[*] USB_SUPPORT --->

<*>Inventra Highspeed Dual Role Controller (TI,ADI,...)

        *****Platform Glue Layer

<*>      Davinci

            Driver Mode  (USB Host)   ---->

配置DM368开启wifi的配置项

网络协议配置开启80211相关协议

[*] Networking support  --->

关闭USB CPPI DMA功能（这里调试了很久，wifi连接上AP，ping也可以ping通一段时间后面就报错，后面尝试着将这个选项关掉，问题解决，但是有缺陷，cpu在做运算密集型操作的时候可能掉包，usb bulk传输有瓶颈）

[*]   Disable DMA (always use PIO) 

2、8188EUS驱动的编译

A、MAKEFILE的修改

驱动版本rtl8188EUS_rtl8189ES_linux_v4.1.7_1529.20140106_B

关闭CONFIG_PLATFORM_I386_PC= n

开启CONFIG_PLATFORM_TI_DM365= y

修改交叉编译器的路径和内核目录路径

ifeq ($(CONFIG_PLATFORM_TI_DM365), y)

EXTRA_CFLAGS += -DCONFIG_LITTLE_ENDIAN-DCONFIG_PLATFORM_TI_DM365

ARCH := arm

CROSS_COMPILE :=/usr/local/ipnc/Source/dvsdk_ipnctools/linux-devkit/bin/arm-arago-linux-gnueabi-

KVER := 2.6.37

KSRC:=/usr/local/yourapp/Source/dvsdk_ipnctools/ipnc_psp_03_21_00_04/kernel

Endif

B、make生成的8188eu.ko拷贝到nfs的文件系统下面,运行下面的命令

加载ko：            insmod 8188eu.ko

打开wlan0：          ifconfig wlan0 up

设置一个同一网段的IP：ifconfig wlan0 192.168.2.103

后台运行wpa_supplicant:  ./wpa_supplicant -Dwext -iwlan0 -c./wpa_supplicant.conf -B &

测试ping网关：        ping 192.168.2.1 &

3、 wireless tools工具和wpa_supplicant工具的交叉编译

进入wireless_tools.30.rtl，

Gcc 改为/usr/local/ipnc/Source/dvsdk_ipnctools/linux-devkit/bin/arm-arago-linux-gnueabi-gcc

AR改为/usr/local/ipnc/Source/dvsdk_ipnctools/linux-devkit/bin/arm-arago-linux-gnueabi-ar

Ranlib改为RANLIB =/usr/local/ipnc/Source/dvsdk_ipnctools/linux-devkit/bin/arm-arago-linux-gnueabi-ranlib

然后编译，将生成的iwconfig、iwevent、iwgetid、iwlist、iwpriv、iwspy拷贝到开发板中

进入wpa_supplicant-0.8

要编译wpa_supplicant工具前先要编译OPENSSL

(A)将openssl解压

Tar zxvf openssl-0.9.8e.tar.gz

(B)将wpa_supplicant下的patch中的openssl-0.9.8e-tls-extensions.patch拷贝到openssl目录下

Cp wpa_supplicant-0.8/patches/openssl-0.9.8e-tls-extensions.patchopenssl-0.9.8e/

(C)patch –p1 <oepnssl-0.9.8e-tls-extensions.patch

(D)Openssl工具的编译

1. 动态链接库

配置安装路径 ./config no-asm shared --prefix=/usr/local/openssl

2.

修改Makefile

CC=/usr/local/ipnc/Source/dvsdk_ipnctools/linux-devkit/bin/arm-arago-linux-gnueabi-gcc

AR=  /usr/local/ipnc/Source/dvsdk_ipnctools/linux-devkit/bin/arm-arago-linux-gnueabi-gcc-ar$(ARFLAGS) r

RANLIB=  /usr/local/ipnc/Source/dvsdk_ipnctools/linux-devkit/bin/arm-arago-linux-gnueabi-gcc-ranlib

make

3.

make install

产生libssl.a及libcrypto.a

 

 

 

 

 

 

Wpa_supplicant工具的编译

进入wpa_supplicant目录

#cp defconfig       .config

#vim .config

CC= arm-linux-gcc -L/usr/local/ssl/lib/

CFLAGS += -I/usr/local/ssl/include/

LIBS += -L/usr/local/ssl/lib/

#make

拷贝工具以及库到目标板

wpa_supplicant用法：

wpa_supplicant-D wext -c ./wpa_supplicant.conf -i wlan0 -B

其中wpa_supplicant.config 可参考内容如下：

ctrl_interface=/var/run/wpa_supplicant

ap_scan=1

network={

proto=RSN

key_mgmt=WPA-PSK

pairwise=CCMPTKIP

group=CCMP TKIP

ssid="TEST"       连接的ap

psk="123456"   密码

}
