【轉】RT3070驅動移植
STA驅動的移植

#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檔案如下（只給出需要修改的部分，“-”表示刪除的行，“+”表示新增的行）：
|
+#Makefile for RT3070 on MBC-SAM9G45 +#2010_11_13 by liyi RT28xx_MODE = STA TARGET = LINUX CHIPSET = 3070 -PLATFORM = PC +PLATFORM = IXP ifeq ($(PLATFORM),IXP) -LINUX_SRC = /project -CROSS_COMPILE = arm-linux- +LINUX_SRC = /home/Embest_SAM9G45/linux-2.6.30 +CROSS_COMPILE = /usr/local/arm2007q1/bin/arm-none-linux-gnueabi- endif |
修改os/linux資料夾中的config.mk檔案，需要修改的地方如下（只給出需要修改的部分）：
|
# Support Wpa_Supplicant - HAS_WPA_SUPPLICANT=n +HAS_WPA_SUPPLICANT=y # Support Native WpaSupplicant for Network Maganger -HAS_NATIVE_WPA_SUPPLICANT_SUPPORT=n +HAS_NATIVE_WPA_SUPPLICANT_SUPPORT=y ifeq ($(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 |
修改完成以後，通過以下命令編譯：
|
make ARCH=arm KBUILD_NOPEDANTIC=1 |
如果不加KBUILD_NOPEDANTIC=1將出現CFLAGS was changed in …. Fix it to use EXTRA_CFLAGS的錯誤，編譯不能通過。編譯完成後，會在os/linux資料夾中生成rt3070sta.ko的驅動模組。此模組通過下載工具可以下載到/mnt目錄。
在驅動目錄下新建一個資料夾Wireless/RT2870STA，將RT2870STA.dat複製進Wireless/RT2870STAm目錄下，同時將此資料夾拷貝進開發板。從超級終端進入開發板目錄/mnt使用以下命令將Wireless資料夾拷貝到/etc目錄下，將rt3070sta.ko拷貝進/home/root使用者目錄下：
|
#cp /mnt/Wireless /usr –r #cp /mnt/rt3070sta.ko /home/root |
開啟root目錄，載入驅動模組：
|
#cd /home/root #insmod rt3070sta.ko |
如果加載出現一下錯誤：
|
#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 [ 2443.155652] rt2070ap: Unknown symbol usb_submit_urb [ 2443.156164] rt2070ap: Unknown symbol usb_control_msg [ 2443.156553] rt2070ap: Unknown symbol usb_deregister [ 2443.157013] rt2070ap: Unknown symbol usb_kill_urb [ 2443.157116] rt2070ap: Unknown symbol usb_buffer_free [ 2443.157443] rt2070ap: Unknown symbol find_vpid [ 2443.157675] rt2070ap: Unknown symbol usb_buffer_alloc |
則需要在檔案os/linux/usb_main_dev.c檔案的開頭加上如下一行程式碼：
|
MODULE_LICENSE(“GPL”); |
然後重新編譯、重新載入，即可得到正確的結果。
用ifconfig-a命令檢視網路，如果載入成功，不會有任何提示，同時可以檢視到ra0裝置的存在。
載入上模組過後，可以用相關命令設定無線網絡卡。命令包括iwpriv、iwconfig、iwlist、ifconfig等。比如設定無線網絡卡地址為192.168.1.5：
|
ifconfig ra0 192.168.1.5 |
設定無線網路模式為ad-hoc模式：
|
iwpriv ra0 set NetworkType=Adhoc |
設定SSID名為isn313：
|
iwconf ra0 essid isn313 |
檢視無線網路：
|
iwlist ra0 scanning |
SoftAP驅動移植
解壓驅動2010_0203_RT3070_SoftAP_v2.4.0.1_DPA.bz2，然後進入目錄：
|
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（“-”表示刪除的行，“+”表示新增的行）：
|
+#Makefile for RT3070 on MBC-SAM9G45 +#2010_11_13 by liyi RT28xx_MODE = AP TARGET = LINUX CHIPSET = 3070 -PLATFORM = PC +PLATFORM = IXP ……… ifeq ($(PLATFORM),IXP) -Linux_SRC = /project……….. -CROSS_COMPILE = arm-linux- +LINUX_SRC = /home/Embest_SAM9G45/linux-2.6.30 +CROSS_COMPILE = /usr/local/arm2007q1/bin/arm-none-linux-gnueabi- endif |
注意，在2010_0203_RT3070_SoftAP_v2.4.0.1_DPA.bz2驅動中，有三個資料夾，分別為MODULE、NETIF、UTIL，在這三個檔案中均有Makefile，所有的Makefile都需要如上修改，同樣，三個資料夾中的config.mk檔案也都需要修改。
修改config.mk配置檔案。
|
ifeq ($(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 |
所有的config.mk都修改好以後，通過以下命令進行編譯：
|
make ARCH=arm KBUILD_NOPEDANTIC=1 |
如果編譯不能通過，請檢查是否所有的資料夾中的Makefile和config.mk都已經修改。編譯通過後，將在三個資料夾中分別生成三個可載入模組：rt3070ap.ko，rtutil3070ap.ko，rtnet3070ap.ko。通過USB介面將這三個模組和rt2870ap.dat檔案下載到開發板目錄下。並將檔案移動到相應位置：
|
#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資料夾中的.dat檔名必須是大寫的，否則模組將無法讀取。
移動好後，進入root目錄並載入模組：
|
#cd /home/root #insmod rtutil3070ap.ko #insmod rt3070ap.ko #insmod rtnet3070ap.ko #ifconfig ra0 up |
此處，載入模組一定要按此順序載入，否則將出現以下錯誤（用dmesg函式可檢視相關錯誤資訊）：
|

在載入過程中若出現以下錯誤：
|
[421.461365] rt3070ap: module license 'RALINK' taints kernel. [421.461723] Disabling lock debugging due to kernel taint |
請修改UTIL/os/linux/usb_main_dev.c檔案，在檔案的開頭加上如下一行程式：
|
MODULE_LICENSE(“GPL”) |
重新編譯：
|
#make clean #make KBUILD_NOPEDANTIC=1 |
然後再重新下載，按順序載入模組即可成功。
模組載入成功後，用一下命令可檢視相關資訊：
