【ARM-Linux开发】Rico Board上编译USB WiFi RT3070驱动

1.附件中提供了RT3070驱动源码包DPO_RT5572_LinuxSTA_2.6.1.3_20121022.tar.gz和编译好的驱动，这里选择使用taget_file.tar.gz中已经编译好的文件，其中还包括了与驱动相匹配的linux-3.12.10内核镜像。
2.将target_file目录下的RT2870STA.dat和rt3070sta.ko拷贝进Rico Board板子中

1 2 3 4 5

mkdir –p /etc/Wireless/RT2870STA/      cp RT2870STA.dat /etc/Wireless/RT2870STA/      cp rt3070sta.ko /home

3.加载驱动

1 2 3 4 5 6 7

root@RicoBoard home# insmod rt3070sta.ko rtusb init rt2870 ---> === pAd = e0936000, size = 512288 ===   <-- RTMPAllocAdapterBlock, Status=0 NVM is EFUSE usbcore: registered new interface driver rt2870

4.然后可以通过ifconfig -a 可以看到系统已经正确识别网卡，名称为ra0
5 启动网卡ifconfig -a 

01 02 03 04 05 06 07 08 09 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31

root@RicoBoard home# ifconfig ra0 up NICLoadFirmware: We need to load firmware <-- RTMPAllocTxRxRingMemory, Status=0 RTMP_TimerListAdd: add timer obj e097e0b8!

注：如果出现ERROR: 256 KiB atomic DMA coherent pool is too small!的错误，请将 coherent_pool=2M，添加在uboot的启动参数qspiargs后面。
6 .配置wpa_supplicant配置文件（wpa_supplicant相关工具已经移植好，包含在我们提供的文件系统中）

1	vi /etc/wpa_supplicant.conf

编辑如下形式

1 2 3 4 5 6 7 8 9

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

注：ssid无线网名字，psk为无线网密码，请根据自己具体路由设置进行编辑配置文件
7.连接 wpa_supplicant -Dwext -ira0 -c/etc/wpa_supplicant.conf&

1 2 3 4 5 6 7 8

root@RicoBoard home# wpa_supplicant -Dwext -ira0 -c/etc/wpa_supplicant.conf& Successfully initialized wpa_supplicant ===>rt_ioctl_giwscan. 7(7) BSS returned, data->length = 1509 ra0: Trying to associate with 38:83:45:2c:c8:00 ==>rt_ioctl_siwfreq::SIOCSIWFREQ(Channel=1) (SSID='TP-LINK-1201' freq=2412 MHz) ra0: Associated with 38:83:45:2c:c8:00 ra0: WPA: Key negotiation completed with 38:83:45:2c:c8:00 [PTK=CCMP GTK=CCMP] ra0: CTRL-EVENT-CONNECTED - Connection to 38:83:45:2c:c8:00 completed [id=0 id_str=]

8.ping通外网

01 02 03 04 05 06 07 08 09 10 11 12
