关于RT3070(RT2870)和wpa_supplicant的使用
2011-04-06 14:10 zhuqing_739 阅读(4344) 评论(1) 编辑 收藏 举报前段时间搞了一下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。
1.首先RT73使用的是rausb0表示的，而RT3070使用ra0表示。
2.RT3070的驱动差不多是RT73的两倍多。
3.另外，在使用wpa_supplicant上也有点小区别，主要是wpa_supplicant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2009_1106_RT3070_Linux_STA_V2.1.1.0.bz2这一版本的编译过去了，呵呵！
交叉编译过程：
1.tar -jxvf 2009_1106_RT3070_Linux_STA_V2.1.1.0.bz2
2. cd 2009_1106_RT3070_Linux_STA_V2.1.1.0
3.vi makefile
- #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
4.cd os/linux
5.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 //
6.cd ../../../
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！！！！！
7.cd http://www.cnblogs.com/..
8.make
这时，应该就编译通过了。在2009_1106_RT3070_Linux_STA_V2.1.1.0/os/linux目录下生成了rt3070sta.ko,也就是RT3070的驱动了。
9.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:""
- Mode:Auto Frequency=2.412 GHz
- 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wireless_tools之前要移植到开发板上！
接下来就是wpa_supplicant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 ./

这些部分就可以略去了，不用做了，呵呵！
顺利地话，就可以在wpa_supplicant-0.6.10\wpa_supplicant下生成wpa_supplicant了！接着就是把wpa_supplicant拷贝到开发板中。
关于wpa_supplicant的使用：
1.把wpa_supplicant.conf拷贝到/etc目录下，当然要根据情况修改wpa_supplicant.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！！！
2.mkdir -p /var/run/wpa_supplicant
3.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
- Key1Str is Invalid key length(0) or Type(0)
- Key2Str is Invalid key length(0) or Type(0)
- Key3Str is Invalid key length(0) or Type(0)
- Key4Str is Invalid key length(0) or Type(0)
- 1. Phy Mode = 9
- 2. Phy Mode = 9
- NVM is Efuse and its size =2d[2d0-2fc]
- 3. Phy Mode = 9
- RTMPSetPhyMode: channel is out of range, use first channel=1
- MCS Set = ff 00 00 00 01
- <==== rt28xx_init, Status=0
- 0x1300 = 00064300
- /mnt $ ===>rt_ioctl_giwscan. 4(4) BSS returned, data->length = 447
- ==>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wpa_supplicant!
可以参考里面的iwpriv_usage.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：
