RT3070和wpa_supplicant

Published: 09 Aug 2013 Category: linux

前段时间搞了一下RT73与wpa_supplicant，调通了，无论是什么加密方式和认证类型，RT73都可以良好的工作。可又由于RT73停产了，被迫要使用RT3070。刚开始我以为应该和RT73差不多，果不其然，用法十分接近，但是也有一点点区别的。

首先RT73使用的是rausb0表示的，而RT3070使用ra0表示。
RT3070的驱动差不多是RT73的两倍多。
另外，在使用wpasupplicant上也有点小区别，主要是wpasupplicant版本的问题。

下面，我就说一下我的使用过程，希望可以帮助到大家！首先是驱动的编译，从网上下了好多RT3070的驱动，都没交叉编译过去，只有20091106RT3070LinuxSTA_V2.1.1.0.bz2这一版本的编译过去了，呵呵！

交叉编译过程：

tar -jxvf 20091106RT3070LinuxSTA_V2.1.1.0.bz2
cd 20091106RT3070LinuxSTA_V2.1.1.0
vi makefile

修改如下：

    #PLATFORM: Target platform
    #PLATFORM = PC
    PLATFORM = 5VT
    #PLATFORM = IKANOS_V160
    #PLATFORM = IKANOS_V180
    #PLATFORM = SIGMA
    #PLATFORM = SIGMA_8622
    #PLATFORM = INIC
    #PLATFORM = STAR
    #PLATFORM = IXP
    #PLATFORM = INF_TWINPASS
    #PLATFORM = INF_DANUBE
    #PLATFORM = BRCM_6358
    #PLATFORM = INF_AMAZON_SE
    #PLATFORM = CAVM_OCTEON
    #PLATFORM = CMPC
    #PLATFORM = RALINK_2880  
    ifeq ($(PLATFORM),5VT)
    LINUX_SRC = /home/Hi3511_VSSDK_V1.1.2.2/pub/kbuild-FULL_REL
    CROSS_COMPILE = arm-hismall-linux-
    endif

cd os/linux

vi config.mk

#ifdef WPA_SUPPLICANT_SUPPORT
#Support Wpa_Supplicant
HAS_WPA_SUPPLICANT=y
#endif // WPA_SUPPLICANT_SUPPORT //
#ifdef NATIVE_WPA_SUPPLICANT_SUPPORT
# Support Native WpaSupplicant for Network Maganger
HAS_NATIVE_WPA_SUPPLICANT_SUPPORT=y
#endif // NATIVE_WPA_SUPPLICANT_SUPPORT //

cd ../../common

vi rtusb_io.c  

if (ret < 0) {
    //DBGPRINT(RT_DEBUG_OFF, ("#/n"));
        RTMPusecDelay(5000);
    }

否则，加载驱动后会一直打印"#",很烦！！！！！

cd ../../..
make 这时，应该就编译通过了。在20091106RT3070LinuxSTA_V2.1.1.0/os/linux目录下生成了rt3070sta.ko,也就是RT3070的驱动了。
把RT2870STA.dat拷贝到/etc/Wireless/RT2870STA目录下加载驱动过程
```
insmod rt3070sta.ko
```

看一下打印消息：

    rtusb init --->


    === pAd = ca901000, size = 465920 ===

    <-- RTMPAllocAdapterBlock, Status=0
    usbcore: registered new driver rt2870

iwconfig看一下

    ra0 RT2870 Wireless ESSID:""

    Link Quality=10/100 Signal level:-256 dBm Noise level:-143 dBm
    Rx invalid nwid:0 Rx invalid crypt:0 Rx invalid frag:0
    Tx excessive retries:0 Invalid misc:0 Missed beacon:0

注意wirelesstools之前要移植到开发板上！接下来就是wpasupplicant的交叉编译，这个比较麻烦，在这里就不详细说明了，给个网址给大家，我也是参考着做的： http://blog.csdn.net/farsight2009/archive/2010/06/10/5660878.aspx 不过，我使用的是0.6.10这个版本，其他版本我都没用起来！由于这个版本比较高，上述网址中的

    #cp ../2009_0713_RT73_Linux_STA_Drv1.1.0.3/WPA_Supplicant-0.5.8/driver_ralink.* ./
    #cp ../2009_0713_RT73_Linux_STA_Drv1.1.0.3/WPA_Supplicant-0.5.8/driver.h ./
    #cp ../2009_0713_RT73_Linux_STA_Drv1.1.0.3/WPA_Supplicant-0.5.8/events.c ./
    #cp ../2009_0713_RT73_Linux_STA_Drv1.1.0.3/WPA_Supplicant-0.5.8/wpa_supplicant.c ./
    #cp ../2009_0713_RT73_Linux_STA_Drv1.1.0.3/WPA_Supplicant-0.5.8/wpa_supplicant_i.h ./
    #cp ../2009_0713_RT73_Linux_STA_Drv1.1.0.3/WPA_Supplicant-0.5.8/defconfig ./
    #cp ../2009_0713_RT73_Linux_STA_Drv1.1.0.3/WPA_Supplicant-0.5.8/drivers.c ./
    #cp ../2009_0713_RT73_Linux_STA_Drv1.1.0.3/WPA_Supplicant-0.5.8/Makefile ./

这些部分就可以略去了，不用做了，呵呵！顺利地话，就可以在wpasupplicant-0.6.10/wpasupplicant下生成wpasupplicant了！接着就是把wpasupplicant拷贝到开发板中。关于wpa_supplicant的使用：

把wpasupplicant.conf拷贝到/etc目录下，当然要根据情况修改wpasupplicant.conf的内容了！这里我提供一个我修改的模板，屡试不爽！

ctrl_interface=/var/run/wpa_supplicant
network={
    ssid="XXXXXX"
    scan_ssid=1
    key_mgmt=WPA-EAP WPA-PSK IEEE8021X NONE    
    pairwise=TKIP CCMP    
    group=CCMP TKIP WEP104 WEP40    
    psk="XXXXXX"
}

其中XXXXXX要替换成相应的ssid和密码！无论是什么加密方式和认证类型，都搞定！WEP除外，因为WEP加密比较简单，在后面会提到，呵呵！！！

mkdir -p /var/run/wpa_supplicant

最后就是用命令

wpa_supplicant -B -ira0 -c /etc/wpa_supplicant.conf -Dwext

看一下超级终端的打印：

    <-- RTMPAllocTxRxRingMemory, Status=0
    -->RTUSBVenderReset
    <--RTUSBVenderReset

    1. Phy Mode = 9
    2. Phy Mode = 9
    NVM is Efuse and its size =2d[2d0-2fc]
    3. Phy Mode = 9

    MCS Set = ff 00 00 00 01

    ==>rt_ioctl_siwfreq::SIOCSIWFREQ[cmd=0x8b04] (Channel=1)

这过程可能要花费几秒钟！接着ifconfig一下它的ip，ping一下无线路由器，应该能ping通的。当然，这些都是让RT3070工作在managed模式下的，工作在ad-hoc模式下的配置跟简单，不需要使用wpasupplicant! 可以参考里面的iwprivusage.txt进行配置，我配置了一下，发现其中有几种情况配置不成功，这里我把配置成功的罗列下来：
