首先在官方的驅動中不一定支持我們需要的平台，這樣就需要我們對需要的平台進行相關的添加，主要修改下面兩個文件：
1、根目錄下的Makefile：
PLATFORM = HI_3518C
#add by kj ,in the platform hi_3518c
ifeq ($(PLATFORM),HI_3518C)
LINUX_SRC = /home/kongjun/mywork/develop_kj/Hi3518_SDK_V1.0.3.0/osdrv/kernel/linux-3.0.y
LINUX_SRC_MODULE = /home/kongjun/mywork/develop_kj/Hi3518_SDK_V1.0.3.0/osdrv/kernel/linux-3.0.y/drivers/net/wireless/
CROSS_COMPILE = arm-hisiv100nptl-linux-
endif
#end alter by kj
2、./os/linux/config.mk 文件：
#add by kj
ifeq ($(PLATFORM),HI_3518C)
#WFLAGS += -DRT_BIG_ENDIAN
endif
#add by kj
ifeq ($(PLATFORM),HI_3518C)
#CFLAGS := -v -D__KERNEL__ -DMODULE -I$(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
export CFLAGS
endif
3、make即可。
注：
驅動加載後生成的設備名稱是‘ra0’，這個在驅動是可以修改的，在驅動中的位置是：
./include/rtmp_def.h
#define INF_MAIN_DEV_NAME "ra"
#define INF_MBSSID_DEV_NAME "ra"
#define INF_WDS_DEV_NAME "wds"
#define INF_APCLI_DEV_NAME "apcli"
#define INF_MESH_DEV_NAME "mesh"
#define INF_P2P_DEV_NAME "p2p"

2. RT3070驅動修改
解壓 tar -zxvf 2011_0107_RT3070_RT3370_Linux_STA_v2.5.0.1_DPO.tar.gz
進入RT3070_Linux_STA目錄，看到有一個README_STA_usb文件，裡面介紹了如何加載該驅動,先浏覽一下
2.1 先設好環境變量
export PATH=/opt/hisi-linux/x86-arm/gcc-3.4.3-uClibc-0.9.28/usr/bin:$PATH
2.2 makefile修改 (-為去掉設置， +為新加的設置)
#vi makefile
- #PLATFORM = PC
+ PLATFORM = IXP
#(選用的是IXP)
ifeq ($(PLATFORM),IXP)
- LINUX_SRC = /project/stable/Gmtek/snapgear-uclibc/linux-2.6.x
- CROSS_COMPILE = arm-linux-
+ LINUX_SRC = /xxx/kernel/linux-2.6.14
+ CROSS_COMPILE = arm-hismall-linux-
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 ($(PLATFORM),IXP)
- WFLAGS += -DRT_BIG_ENDIAN
#加這個選項，模塊運行時顯示出錯，CPU不能工作
endif
ifeq ($(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
export CFLAGS
endif
3、 編譯源碼
make通過,在2011_0107_RT3070_RT3370_Linux_STA_v2.5.0.1_DPO/os/linux目錄下生成了rt3070sta.ko,也就是RT3070的驅動了
4. 拷貝驅動到目標系統
把RT2870STA.dat拷貝到/etc/Wireless/RT2870STA目錄下
把rt3070sta.ko拷貝到/xxx/ 目錄下 xxx自定
5. 加載驅動模塊
insmod /xxx/rt3070sta.ko
出現以下錯誤
rt3070sta: Unknown symbol usb_alloc_urb
rt3070sta: Unknown symbol usb_free_urb
rt3070sta: Unknown symbol usb_register
rt3070sta: Unknown symbol usb_put_dev
rt3070sta: Unknown symbol usb_get_dev
rt3070sta: Unknown symbol usb_submit_urb
rt3070sta: Unknown symbol usb_control_msg
rt3070sta: Unknown symbol usb_deregister
rt3070sta: Unknown symbol usb_kill_urb
rt3070sta: Unknown symbol usb_buffer_free
rt3070sta: Unknown symbol usb_buffer_alloc
insmod: cannot insert `rt3070sta.ko': Unknown symbol in module (-1): No such file or directory
原因未加載USB驅動
5.1 加載usbcore.ko
insmod /lib/modules/2.6.14-hi3511v100dmeb-release/kernel/drivers/usb/core/usbcore.ko
顯示
usbcore: registered new driver usbfs
usbcore: registered new driver hub
加載成功
5.2.1 如果為USB1.1 加載hi3511_usb_1-1.ko
insmod /lib/modules/2.6.14-hi3511v100dmeb-release/misc/hi3511_usb_1-1.ko
顯示

5.2.2 如果為USB2.0 加載hiusb.ko
insmod /lib/modules/2.6.14-hi3511v100dmeb-release/misc/hiusb.ko
顯示
<6>hiusb-hcd hiusb-hcd.0: Hisilicon USB host controller

hub 1-0:1.0: USB hub found
hub 1-0:1.0: 1 port detected
加載成功
5.3 然後再加載rt3070sta.ko
insmod /xxx/rt3070sta.ko
顯示
rtusb init rt2870 --->
=== pAd = d1af4000, size = 514424 ===
<-- RTMPAllocTxRxRingMemory, Status=0
<-- RTMPAllocAdapterBlock, Status=0
usbcore: registered new driver rt2870
加載成功
#ifconfig -a 可以查看到ra0設備的存在
若無密碼或密碼為WEP加密，則此時可以啟動無線, 若密碼為WPA加密,則需移植wpa_supplicant,往後再說移植
6.無密碼或密碼為WEP加密:
6.1 啟動無線

啟動成功
6.2 設置ip
#ifconfig ra0 192.168.1.230 netmask 255.255.255.0
6.3 掃描無線網絡
#iwlist ra0 scan
===>rt_ioctl_giwscan. 9(9) BSS returned, data->length = 1476
ra0 Scan completed :

顯示以上信息說明模塊已經正常工作
6.4 設置SSID和WEP加密算法
可以參考裡面的iwpriv_usage.txt進行配置，
6.4.1 無密碼
Config STA to link with AP which is OPEN/NONE(Authentication/Encryption)
1. iwpriv ra0 set NetworkType=Infra
2. iwpriv ra0 set AuthMode=OPEN
3. iwpriv ra0 set EncrypType=NONE
4. iwpriv ra0 set SSID="AP's SSID"
6.4.2 WEP加密算法
iwpriv ra0 set NetworkType=Infra
iwpriv ra0 set AuthMode=SHARED
iwpriv ra0 set EncrypType=WEP
iwpriv ra0 set DefaultKeyID=1
iwpriv ra0 set Key1="AP's wep key"
iwpriv ra0 set SSID="AP's SSID"
設置完一會，等網絡連接好就可以了。
