RT3070驱动移植

无线网卡为RT3070，驱动分为STA驱动和SoftAP驱动两种，STA驱动支持无线网卡工作在STA模式下，而SoftAP的驱动支持无线网卡工作在软AP的模式下，可以作为一个软的接入点。STA驱动为2010_0831_RT3070_Linux_STA_v2.3.0.0_DPO.bz2。SoftAP的驱动是：2010_0203_RT3070_SoftAP_v2.4.0.1_DPA.bz2。需要移植STA驱动和SoftAP驱动，两款驱动的移植步骤差不多。下边首先对STA驱动进行移植。

 

STA驱动的移植

 

#tar jxvf 2010_0831_RT3070_Linux_STA_v2.3.0.0_DPO.bz2

cd 2010_0831_RT3070_Linux_STA_v2.3.0.0_DPO

修改原有的Makefile文件如下（只给出需要修改的部分，“-”表示删除的行，“+”表示添加的行）：

+#Makefile for RT3070 on MBC-SAM9G45

+#2010_11_13 by liyi

RT28xx_MODE = STA

TARGET = LINUX

CHIPSET = 3070

-PLATFORM = PC

+PLATFORM = IXP

 

ifeq ($(PLATFORM),IXP)

-LINUX_SRC = /project

-CROSS_COMPILE = arm-linux-

+LINUX_SRC = /home/Embest_SAM9G45/linux-2.6.30

+CROSS_COMPILE = /usr/local/arm2007q1/bin/arm-none-linux-gnueabi-

endif

修改os/linux文件夹中的config.mk文件，需要修改的地方如下（只给出需要修改的部分）：

# 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

+#WFLAGS += -DRT_BIG_ENDIAN

endif

 

ifeq ($(PLATFORM),IXP)

        EXTRA_CFLAGS := -v $(WFLAGS) -I$(RT28xx_DIR)/include

endif

 

ifeq ($(PLATFORM),IXP)

-         CFLAGS := -v -D__KERNEL__ -DMODULE -I$(LINUX_SRC)/include -I$(RT28xx_DIR)/include -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

-         export CFLAGS       

-

+

endif

修改完成以后，通过以下命令编译：

make ARCH=arm KBUILD_NOPEDANTIC=1

如果不加KBUILD_NOPEDANTIC=1将出现CFLAGS was changed in …. Fix it to use EXTRA_CFLAGS的错误，编译不能通过。编译完成后，会在os/linux文件夹中生成rt3070sta.ko的驱动模块。此模块通过下载工具可以下载到/mnt目录。

在驱动目录下新建一个文件夹Wireless/RT2870STA，将RT2870STA.dat复制进Wireless/RT2870STAm目录下，同时将此文件夹拷贝进开发板。从超级终端进入开发板目录/mnt使用以下命令将Wireless文件夹拷贝到/etc目录下，将rt3070sta.ko拷贝进/home/root用户目录下：

#cp /mnt/Wireless /usr –r

#cp /mnt/rt3070sta.ko /home/root

打开root目录，加载驱动模块：

#cd /home/root

#insmod rt3070sta.ko

如果加载出现一下错误：

#insmod rt3070sta.ko

insmod: error inserting 'rt3070sta.ko': -1 Unknown symbol in module

#dmesg | grep rt3070

[ 2443.154486] rt2070ap: Unknown symbol usb_alloc_urb

[ 2443.154628] rt2070ap: Unknown symbol usb_free_urb

[ 2443.155032] rt2070ap: Unknown symbol usb_register_driver

[ 2443.155324] rt2070ap: Unknown symbol usb_put_dev

[ 2443.155439] rt2070ap: Unknown symbol usb_get_dev

[ 2443.157116] rt2070ap: Unknown symbol usb_buffer_free

[ 2443.157443] rt2070ap: Unknown symbol find_vpid

[ 2443.157675] rt2070ap: Unknown symbol usb_buffer_alloc

则需要在文件os/linux/usb_main_dev.c文件的开头加上如下一行代码：

MODULE_LICENSE(“GPL”);

然后重新编译、重新加载，即可得到正确的结果。

用ifconfig  -a命令查看网络，如果加载成功，不会有任何提示，同时可以查看到ra0设备的存在。

加载上模块过后，可以用相关命令设置无线网卡。命令包括iwpriv、iwconfig、iwlist、ifconfig等。比如设置无线网卡地址为192.168.1.5：

ifconfig ra0 192.168.1.5

设置无线网络模式为ad-hoc模式：

iwpriv ra0 set NetworkType=Adhoc

设置SSID名为isn313：

iwconf ra0 essid isn313

查看无线网络：

iwlist ra0 scanning

SoftAP驱动移植

解压驱动2010_0203_RT3070_SoftAP_v2.4.0.1_DPA.bz2，然后进入目录：

tar jxvf 2010_0203_RT3070_SoftAP_v2.4.0.1_DPA.bz2

cd 2010_0203_RT3070_SoftAP_v2.4.0.1_DPA

修改Makefile如下（“-”表示删除的行，“+”表示添加的行）：

+#Makefile for RT3070 on MBC-SAM9G45

+#2010_11_13 by liyi

RT28xx_MODE = AP

TARGET = LINUX

CHIPSET = 3070

-PLATFORM = PC

+PLATFORM = IXP

………

ifeq ($(PLATFORM),IXP)

-Linux_SRC = /project………..

-CROSS_COMPILE = arm-linux-

+LINUX_SRC = /home/Embest_SAM9G45/linux-2.6.30

+CROSS_COMPILE = /usr/local/arm2007q1/bin/arm-none-linux-gnueabi-

endif

注意，在2010_0203_RT3070_SoftAP_v2.4.0.1_DPA.bz2驱动中，有三个文件夹，分别为MODULE、NETIF、UTIL，在这三个文件中均有Makefile，所有的Makefile都需要如上修改，同样，三个文件夹中的config.mk文件也都需要修改。

修改config.mk配置文件。

ifeq ($(PLATFORM),IXP)

- WFLAGS += -DRT_BIG_ENDIAN

+#WFLAGS += -DRT_BIG_ENDIAN

endif

 

ifeq ($(PLATFORM),IXP)

#WFLAGS += -DRT_BIG_ENDIAN

endif

 

ifeq ($(PLATFORM),IXP)

CFLAGS := -v -D__KERNEL__ -DMODULE -I$(LINUX_SRC)/include -I$(RT28xx_DIR)/include -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

export CFLAGS       

endif

 

对不起，在修改驱动config.mk文件的时候，红色修改部分没有给全，应该是把CFLAGS和EXTRA_FLAGS中的-mbig-endian选项去掉，因为在ARM中采用的小端模式！特此更正！

 

 

所有的config.mk都修改好以后，通过以下命令进行编译：

make ARCH=arm KBUILD_NOPEDANTIC=1

如果编译不能通过，请检查是否所有的文件夹中的Makefile和config.mk都已经修改。编译通过后，将在三个文件夹中分别生成三个可加载模块：rt3070ap.ko，rtutil3070ap.ko，rtnet3070ap.ko。通过USB接口将这三个模块和rt2870ap.dat文件下载到开发板目录下。并将文件移动到相应位置：

#mkdir /etc/Wireless/

#mkdir /etc/Wireless/RT2870AP/

#cp /mnt/rt2870ap.dat /etc/Wireless/RT2870AP/RT2870AP.dat

#cp /mnt/rt3070ap.ko /home/root

#cp /mnt/rtutil3070ap.ko /home/root

#cp /mnt/rtnet3070ap.ko /home/root

第三行中，在RT2870AP文件夹中的.dat文件名必须是大写的，否则模块将无法读取。

移动好后，进入root目录并加载模块：

#cd /home/root

#insmod rtutil3070ap.ko

#insmod rt3070ap.ko

#insmod rtnet3070ap.ko

#ifconfig ra0 up

此处，加载模块一定要按此顺序加载，否则将出现以下错误（用dmesg函数可查看相关错误信息）：

#insmod rt3070sta.ko

insmod: error inserting 'rt3070sta.ko': -1 Unknown symbol in module

#dmesg | grep rt3070

在加载过程中若出现以下错误：

[421.461365] rt3070ap: module license 'RALINK' taints kernel.

[421.461723] Disabling lock debugging due to kernel taint

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：

#make clean

#make KBUILD_NOPEDANTIC=1

然后再重新下载，按顺序加载模块即可成功。

模块加载成功后，用一下命令可查看相关信息：

#ifconfig –a

          Mode:Managed  Channel=11  Access Point: 00:0C:43:41:6F:A6

          Bit Rate=150 Mb/s

用ifconfig命令设定ra0的IP地址：

#ifconfig ra0 192.168.1.1

ra0       Link encap:Ethernet  HWaddr 00:0C:43:41:6F:A6

          inet addr:192.168.1.1  Bcast:192.168.1.255  Mask:255.255.255.0

          collisions:0 txqueuelen:1000

          RX bytes:121922 (119.0 KiB)  TX bytes:9072 (8.8 KiB)

至此，一个默认的名为RT2860AP的网络就建立起来了。用iwconfig命令可修改网络的相关参数。如：

#iwconfig ra0 set SSID=”RT_AP”

#iwconfig ra0

ra0       RTWIFI SoftAP  ESSID:"RT_AP"  Nickname:""

          Mode:Managed  Channel=11  Access Point: 00:0C:43:41:6F:A6

          Bit Rate=150 Mb/s

结束后，可以通过以下命令卸载模块：

#ifconfig ra0 down

#rmmod rtnet3070ap.ko

#rmmod rt3070ap.ko

#rmmod rtutil3070ap.ko
