在ubuntu10.04下移植,下面记录过程。

版本:wpa_supplicant-2.0.tar.gz

           openssl-1.0.1e

编译器:linaro - arm-linux-gcc-4.7.3

备注:

经过测试发现openssl-0.9.8e + wpa_supplicant-0.7.3 or wpa_supplicant-2.0 连接时会出错:

> wlan0: authenticate with 48:02:2a:17:84:55

然后使用openssl-1.0.1e版本+wpa_supplicant2.0版本可以正常连接。

------------------------------------------------------------------------------------------------------------------

先移植openssl-1.0.1e:
./config no-asm shared --prefix=/home/xuewt/share/yocto/build/tmp/work/socfpga_cyclone5-poky-linux-gnueabi/altera-image-1.0-r0/wireless/openssl-1.0.1e/_install

shared表示要生成动态库,否则默认生成的是静态库。


再移植wpa_supplicant2.0:
vi .config
CC=arm-linux-gnueabihf-gcc  -L/home/xuewt/share/yocto/build/tmp/work/socfpga_cyclone5-poky-linux-gnueabi/altera-image-1.0-r0/wireless/openssl-1.0.1e/_install/lib/
CFLAGS +=-I/home/xuewt/share/yocto/build/tmp/work/socfpga_cyclone5-poky-linux-gnueabi/altera-image-1.0-r0/wireless/openssl-1.0.1e/_install/include/
LIBS +=-L/home/xuewt/share/yocto/build/tmp/work/socfpga_cyclone5-poky-linux-gnueabi/altera-image-1.0-r0/wireless/openssl-1.0.1e/_install/lib/

注意如果出现netlink编译错误,可以把.config中netlink driver配置屏蔽掉,在wpa-0.7.3默认是屏蔽掉的。
然后make,就会在当前目录下生成3个我们需要的文件:wpa_supplicant,wpa_cli,wpa_passphrase。


cp wpa_supplicant/examples/wpa-psk-tkip.conf   wpa_supplicant.conf


编辑conf的内容:

network={
        ssid="name"
        #psk="123456"
        key_mgmt=WPA-PSK
        proto=WPA
        pairwise=TKIP
        group=TKIP
        #priority=20
        psk=fa4b84264af8dcf3876f3c612d52dea90c3d20c0fedfd87775144ea0a463ad55
        #frequency=2412
}   

./wpa_passphrase ssid name 123456 就会生成一个加密后的密码,然后把这个密码填到conf文件里,把明码屏蔽掉,如上所示。

然后把它们下载到开发板上。


ifconfig eth0 down

ifconfig wlan0 up

./wpa_supplicant -Dwext -iwlan0 -c/etc/wpa_supplicant.conf -B    

-B表示是个守护进程,在后台一直运行。 -Dwext 表示使用扩展WIFI接口。

./wpa_cli scan

./wpa_cli scan_results

./wpa_cli


add_network  添加一个网络,假设返回0

set_network 0 ssid "name"  设置用户名

有密码时:set_network 0 psk "123456"
没有密码时:set_network 0 key_mgmt NONE

select_network 0
enable_network 0

udhcpc -i wlan0  动态获取IP


然后可以使用wget去网络下载一些文件测试一下稳定性。


备注:删除指定网络0:./wpa_cli remove_network 0
