【ARM-Linux開發】Rico Board上編譯USB WiFi RT3070驅動

1.附件中提供了RT3070驅動源碼包DPO_RT5572_LinuxSTA_2.6.1.3_20121022.tar.gz和編譯好的驅動，這裡選擇使用taget_file.tar.gz中已經編譯好的檔案，其中還包括了與驅動相比對的linux-3.12.10核心鏡像。

2.将target_file目錄下的RT2870STA.dat和rt3070sta.ko拷貝進Rico Board闆子中

1 2 3 4 5

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

3.加載驅動

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.然後可以通過ifconfig -a 可以看到系統已經正确識别網卡，名稱為ra0

5 啟動網卡ifconfig -a 

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：如果出現ERROR: 256 KiB atomic DMA coherent pool is too small!的錯誤，請将 coherent_pool=2M，添加在uboot的啟動參數qspiargs後面。

6 .配置wpa_supplicant配置檔案（wpa_supplicant相關工具已經移植好，包含在我們提供的檔案系統中）

vi / etc / wpa_supplicant.conf

編輯如下形式

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無線網名字，psk為無線網密碼，請根據自己具體路由設定進行編輯配置檔案

7.連接配接 wpa_supplicant -Dwext -ira0 -c/etc/wpa_supplicant.conf&

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通外網

root@RicoBoard home # ifconfig ra0 192.168.1.24 netmask 255.255.255.0 root@RicoBoard home # route add default gw 192.168.1.1 root@RicoBoard home # ping [url=http://www.baidu.com]www.baidu.com[/url] PING [url=http: //www .baidu.com]www.baidu.com[ /url ] (119.75.217.109): 56 data bytes 64 bytes from 119.75.217.109: seq =0 ttl=53 time =72.089 ms 64 bytes from 119.75.217.109: seq =1 ttl=53 time =73.024 ms 64 bytes from 119.75.217.109: seq =2 ttl=53 time =72.862 ms 64 bytes from 119.75.217.109: seq =3 ttl=53 time =73.278 ms 64 bytes from 119.75.217.109: seq =4 ttl=53 time =73.044 ms 64 bytes from 119.75.217.109: seq =5 ttl=53 time =72.439 ms 64 bytes from 119.75.217.109: seq =6 ttl=53 time =72.777 ms 64 bytes from 119.75.217.109: seq =7 ttl=53 time =73.292 ms
