嵌入式 RT3070_STA驱动移植到hi3518c平台小结

首先在官方的驱动中不一定支持我们需要的平台，这样就需要我们对需要的平台进行相关的添加，主要修改下面两个文件：

1、根目录下的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：

驱动加载后生成的设备名称是‘ra0’，这个在驱动是可以修改的，在驱动中的位置是：
./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
export PATH=/opt/hisi-linux/x86-arm/gcc-3.4.3-uClibc-0.9.28/usr/bin:$PATH

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

- #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 = /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
export CFLAGS
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

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
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

原因未加载USB驱动

5.1 加载usbcore.ko
insmod /lib/modules/2.6.14-hi3511v100dmeb-release/kernel/drivers/usb/core/usbcore.ko

显示
usbcore: registered new driver usbfs
usbcore: registered new driver hub
加载成功

5.2.1 如果为USB1.1 加载hi3511_usb_1-1.ko

insmod /lib/modules/2.6.14-hi3511v100dmeb-release/misc/hi3511_usb_1-1.ko

显示
USB1_1-M0001C030002 @Hi3511v110_OSDrv_1_0_0_1 2008-11-03 18:35:15

hub 1-0:1.0: USB hub found
hub 1-0:1.0: 2 ports detected
usb 1-1: new full speed USB device using hisilicon-ohci and address 2
加载成功

5.2.2 如果为USB2.0 加载hiusb.ko

insmod /lib/modules/2.6.14-hi3511v100dmeb-release/misc/hiusb.ko

显示
<6>hiusb-hcd hiusb-hcd.0: Hisilicon USB host controller
hiusb-hcd hiusb-hcd.0: new USB bus registered, assigned bus number 1
hiusb-hcd hiusb-hcd.0: irq 23, io base 0x80090000
hub 1-0:1.0: USB hub found
hub 1-0:1.0: 1 port detected

加载成功

5.3 然后再加载rt3070sta.ko
insmod /xxx/rt3070sta.ko
显示
rtusb init 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

启动成功

6.2 设置ip
#ifconfig ra0 192.168.1.230 netmask 255.255.255.0

6.3 扫描无线网络
#iwlist ra0 scan
===>rt_ioctl_giwscan. 9(9) BSS returned, data->length = 1476
ra0 Scan completed :
Cell 01 - Address: F0:7D:68:96:A6:C2

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
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"

设置完一会，等网络连接好就可以了。
