1.下载RT3070驱动源码
版本：2011_0107_RT3070_RT3370_Linux_STA_v2.5.0.1_DPO
download: 下载页面

选到 T8070/RT3070/RT3370/RT5370/RT5372USB  这个然后随便输入名字和邮箱即可下载。

 

2.RT3070驱动修改

解压 tar-zxvf 2011_0107_RT3070_RT3370_Linux_STA_v2.5.0.1_DPO.tar.gz

进入RT3070_Linux_STA目录，看到有一个README_STA_usb文件，里面介绍了如何加载该驱动,先浏览一下

 

2.1 先设好环境变量
exportPATH=/usr/local/arm/arm-2007q1/bin:$PATH

 

2.2 makefile修改 (-为去掉设置，+为新加的设置)
#vimakefile

-#PLATFORM = PC
+ PLATFORM = IXP
#(选用的是IXP)

ifeq($(PLATFORM),IXP)

-LINUX_SRC = /project/stable/Gmtek/snapgear-uclibc/linux-2.6.x
-CROSS_COMPILE = arm-linux-
+ LINUX_SRC = /home/rpf413/at91/linux/linux-2.6.30
+ CROSS_COMPILE = /usr/local/arm/arm-2007q1/bin/arm-none-linux-gnueabi-
endif

2.3 /os/linux/config.mk修改
#cd/os/linux/
#vi config.mk

#Support Wpa_Supplicant
- HAS_WPA_SUPPLICANT=n
+HAS_WPA_SUPPLICANT=y

#Support Native WpaSupplicant for Network Maganger
-HAS_NATIVE_WPA_SUPPLICANT_SUPPORT=n
+HAS_NATIVE_WPA_SUPPLICANT_SUPPORT=y

ifeq($(PLATFORM),IXP)
- WFLAGS +=-DRT_BIG_ENDIAN
#加这个选项，模块运行时显示出错，CPU不能工作
endif

ifeq($(PLATFORM),IXP)

 -CFLAGS := -v -D__KERNEL__ -DMODULE -I$(LINUX_SRC)/include-I$(RT28xx_DIR)/include -mbig-endian -Wall -Wstrict-prototypes-Wno-trigraphs -O2 -fno-strict-aliasing -fno-common -Uarm -fno-common-pipe -mapcs-32 -D__LINUX_ARM_ARCH__=5 -mcpu=xscale -mtune=xscale-malignment-traps -msoft-float $(WFLAGS)
        -EXTRA_CFLAGS := -v $(WFLAGS) -I$(RT28xx_DIR)/include -mbig-endian
 +EXTRA_CFLAGS := -v $(WFLAGS) -I$(RT28xx_DIR)/include
 exportCFLAGS       
endif

 

3、  编译源码
make通过,在2011_0107_RT3070_RT3370_Linux_STA_v2.5.0.1_DPO/os/linux目录下生成了rt3070sta.ko,也就是RT3070的驱动了

 makeKBUILD_NOPEDANTIC=1

4.   拷贝驱动到目标系统
把RT2870STA.dat拷贝到/etc/Wireless/RT2870STA目录下
把rt3070sta.ko拷贝到/xxx/目录下xxx自定

 

5.加载驱动模块
insmod/xxx/rt3070sta.ko

出现以下错误

insmod:error inserting 'rt3070sta.ko': -1 Unknown symbol inmodule
rt3070sta: Unknown symbol usb_alloc_urb
rt3070sta:Unknown symbol usb_free_urb
rt3070sta: Unknown symbolusb_register
rt3070sta: Unknown symbol usb_put_dev
rt3070sta:Unknown symbol usb_get_dev
rt3070sta: Unknown symbolusb_submit_urb
rt3070sta: Unknown symbolusb_control_msg
rt3070sta: Unknown symbolusb_deregister
rt3070sta: Unknown symbol usb_kill_urb
rt3070sta:Unknown symbol usb_buffer_free
rt3070sta: Unknown symbolusb_buffer_alloc
insmod: cannot insert `rt3070sta.ko': Unknownsymbol in module (-1): No such file or directory

原因未加载USB驱动

请修改UTIL/os/linux/usb_main_dev.c文件，在文件的开头加上如下一行程序：

MODULE_LICENSE(“GPL”)

重新编译：

MakeARCH=armCROSS_COMPILE=/usr/local/arm/arm-2007q1/bin/arm-none-linux-gnueabi-

  

5.3 然后再加载rt3070sta.ko

手动添加：/etc/Wireless/RT2870STA/RT2870STA.dat
insmod/xxx/rt3070sta.ko
显示
rtusbinit rt2870 --->

===pAd = d1af4000, size = 514424 ===

<--RTMPAllocTxRxRingMemory, Status=0
<-- RTMPAllocAdapterBlock,Status=0
usbcore: registered new driver rt2870
加载成功

#ifconfig-a 可以查看到ra0设备的存在

若无密码或密码为WEP加密，则此时可以启动无线,若密码为WPA加密,则需移植wpa_supplicant,往后再说移植

 

6.无密码或密码为WEP加密:
6.1 启动无线
#ifconfigra0 up

启动成功

 

6.2 设置ip
#ifconfigra0 192.168.50.166 netmask 255.255.255.0

 

6.3 扫描无线网络
#iwlistra0 scan
===>rt_ioctl_giwscan.9(9) BSS returned, data->length = 1476
ra0       Scancompleted :

                    Quality=18/100  Signallevel=-83 dBm  Noise level=-91dBm
                    Encryptionkey:off
                    BitRates:54 Mb/s

显示以上信息说明模块已经正常工作

 

6.4 设置SSID和WEP加密算法
可以参考里面的iwpriv_usage.txt进行配置，

6.4.1 无密码
ConfigSTA to link with AP which is OPEN/NONE(Authentication/Encryption)
1.iwpriv ra0 set NetworkType=Infra
2. iwpriv ra0 setAuthMode=OPEN
3. iwpriv ra0 set EncrypType=NONE
4. iwpriv ra0set SSID="AP's SSID"

 

6.4.2 WEP加密算法
iwprivra0 set NetworkType=Infra
iwpriv ra0 set AuthMode=SHARED
iwprivra0 set EncrypType=WEP
iwpriv ra0 set DefaultKeyID=1
iwpriv ra0set Key1="AP's wep key"
iwpriv ra0 set SSID="AP'sSSID"

设置完一会，等网络连接好就可以了。

WPA加密详见openssl驱动移植，wpa_supplicant驱动移植。
