Hi3518E开发板上添加RT5370模块

最近在搞摄像头，手上雄迈的3518e板子引出了usb接口，正好也扒出来一块带着rt5370的小板，然后焊点线就行了，剩下的就是搞移植了。

0.准备工作

虚拟机中已正常安装海思交叉工具链且path也export了，这里使用arm-hisiv100nptl-linux，内核代码，这里是linux-3.0.y，绝对路径为/work/hi3518/linux-3.0.y。

待移植源码
2011_0719_RT3070_RT3370_RT5370_RT5372_Linux_STA_V2.5.0.3_DPO.bz2
openssl-1.0.1e.tar.gz
wpa_supplicant-0.7.3.tar.gz
wireless_tools.29.tar.gz

1.配置内核
Networking support==>Wireless 下80211相关配置选上，至于debug开关酌情考虑
Device Drivers==>Network deivce support==>Wireless LAN==><*> USB ZD1201 based Wireless device support
Device Drivers==>USB support下EHCI HCD support、OHCI HCD support 、USB Wireless Device Management support
make uImage

2.移植rt5370驱动

a.解压源码

2011_0719_RT3070_RT3370_RT5370_RT5372_Linux_STA_V2.5.0.3_DPO.bz2

b.修改顶层Makefile
修改平台为Hi3518E：
#PLATFORM = PC
PLATFORM = HI3518E
添加平台内核路径及编译工具
ifeq ($(PLATFORM),HI3518E)
LINUX_SRC = /work/hi3518/linux-3.0.y
CROSS_COMPILE = arm-hisiv100nptl-linux-
endif
c.修改配置文件
修改os/linux/config.mk
使能wpa supplicant
# Support Wpa_Supplicant
HAS_WPA_SUPPLICANT=y
# Support Native WpaSupplicant for Network Maganger
HAS_NATIVE_WPA_SUPPLICANT_SUPPORT=y
添加平台的EXTRT_CFLAGS
ifeq ($(PLATFORM),HI3518E) 
EXTRA_CFLAGS := $(WFLAGS) -I$(RT28xx_DIR)/include
endif
d.修改设备名称
修改include/rtmp_def.h
将宏
#define INF_MAIN_DEV_NAME"ra"
#define INF_MBSSID_DEV_NAME"ra"
修改为
#define INF_MAIN_DEV_NAME"wlan"
#define INF_MBSSID_DEV_NAME"wlan"
这样加载驱动后，添加的网卡名称为wlan0
e.编译 make
f.部署到开发板饿
将os/linux/rt5370sta.ko放入开发板ko目录下
将RT2870STA.dat放入开发板/etc/Wireless/RT2870STA/目录下
f.加载5370驱动
#insmod rt5370sta.ko
#rtusb init rt2870 --->

=== pAd = c31c3000, size = 510192 ===

 RTMPAllocTxRxRingMemory, Status=0
 RTMPAllocAdapterBlock, Status=0
usbcore: registered new interface driver rt2870

ifconfig -a  之后会看到有个wlan0

#ifconfig wlan0 up

3.移植wpa supplicant
wpa supplicant需要用到ssl库,为此需先编译openssl，
a.解压源码
解压openssl-1.0.1e.tar.gz与wpa_supplicant-0.7.3.tar.gz
b.编译OpenSSL库
将上一步解压出来wpa_supplicant-0.7.3中的patches/openssl-0.9.8e-tls-extensions.patch复制到openssl-1.0.1e目录下。
建立一个openssl的安装目录，例如work/hi3518/openssl.
修改顶层Makefile
CC= arm-hisiv100nptl-linux-gcc
AR= arm-hisiv100nptl-linux-ar $(ARFLAGS) r
RANLIB= arm-hisiv100nptl-linux-ranlib
INSTALLTOP=/work/hi3518/openssl
OPENSSLDIR=/work/hi3518/openssl
make
make install
c.编译wpa_suppicant
进入目录wpa_supplicant-0.7.3/wpa_supplicant,
cp defconfig .config
修改.config
CC=arm-hisiv100nptl-linux-gcc -L/work/hi3518/openssl/lib/
CFLAGS += -I/work/hi3518/openssl/include
LIBS += -L/work/hi3518/openssl/lib/
编译make
d.部署到开发板
将编译生成的wpa_supplicant、wpa_cli下载到开发板
创建配置文件/etc/wap_supplicant.conf，内容如下：
ctrl_interface=/var/run/wpa_supplicant

network={
ssid="Test-Wifi"
scan_ssid=1
key_mgmt= WPA-EAP WPA-PSK IEEE8021X NONE
pairwise=TKIP CCMP
group=CCMP TKIP WEP104 WEP40
psk="12345678"

}

创建运行目录mkdir /var/run/wpa_supplicant,上面配置文件中ssid、psk为路由wifi名称与密码
e.连接到路由
运行命令
./wpa_supplicant -Dwext -iwlan0 -c/home/wpa_supplicant.conf -dd &
这里-dd可以去掉，关闭调试信息。
这样3518就连接到了路由，路由ssid、密码在wpa_supplicant.conf中配置
f.自动获得ip
busybox中已默认包含udhcpc，只需要在开发板中做配置运行即可
复制busybox中example/udhcp/simple.script到开发板etc目录下，根据其中的RESOLV_CONF="/etc/resolv.conf"在etc下建立resolv.conf文件，修改权限为777

运行命令 udhcpc -i wlan0 -s /etc/udhcpc-default.script &
开发板能够从路由获得ip

4.移植wireless_tools
a.解压源码，修改Makefile
CC = arm-hisiv100nptl-linux-gcc
AR = arm-hisiv100nptl-linux-ar
RANLIB = arm-hisiv100nptl-linux-ranlib
b.编译make

c.部署到开发板

将编译生成的libiw.so.29放到开发板/usr/lib/目录下

将编译生成的iwlist、iwconfig、iwpriv等下载到开发板运行即可，具体使用可查找相关资料。
