海思Hi3518E移植WIFI驱动(STA模式)

1. 移植驱动

源码下载：

链接：https://pan.baidu.com/s/1EXGMkPs8-GxsdyK0735Sqw
提取码：bx5c

(1)include/rtmp_def.h中1627行左右，修改网络名始终为：wlan

(2)修改Makefile

原来默认的平台是PC，然后添加平台

添加Linux内核源码路径，编译工具链，CPU

ifeq ($(PLATFORM),HISI_3518E)
LINUX_SRC = /home/aston/sambashare/Hi3518E_SDK_V1.0.3.0/osdrv/opensource/kernel/linux-3.4.y
CROSS_COMPILE = arm-hisiv300-linux-
export ARCH = arm
endif

在402行：修改为HISI_3518E

ifeq ($(PLATFORM),DM6446)
    $(MAKE)  ARCH=arm CROSS_COMPILE=arm_v5t_le- -C  $(LINUX_SRC) SUBDIRS=$(RT28xx_DIR)/os/linux modules
else
ifeq ($(PLATFORM),HISI_3518E)//《——————
    $(MAKE) ARCH=arm CROSS_COMPILE=$(CROSS_COMPILE) -C  $(LINUX_SRC) SUBDIRS=$(RT28xx_DIR)/os/linux modules
else
    $(MAKE) -C $(LINUX_SRC) SUBDIRS=$(RT28xx_DIR)/os/linux modules
endif
endif

错误1：

  CC [M]  /home/aston/sambashare/5季/ap/mt7601u/os/linux/../../os/linux/rt_profile.o
/home/aston/sambashare/5季/ap/mt7601u/os/linux/../../os/linux/rt_profile.c:26:23: fatal 
error: rt_config.h: No such file or directory
 #include "rt_config.h"

主要原因是：在编译 ./os/linux/rt_profile.c 的时候找不到文件 rt_config.h 这是因为plags没有设置好

修改：在 ./os/linux/config.mk 中添加

最后编译成功：在 ./os/linux/ 下会生成KO文件 mt7601Uap.ko ，并且向 /tftp/ 下复制一份

为把KO文件复制到我们需要的目录下，因此修改Makefile

2. 部署驱动

(1)先lsusb，然后插入USB WIFI模块，再lsusb，确认模块被识别了

/mnt # lsusb
Bus 001 Device 003: ID 148f:7601  //我的开发板
Bus 001 Device 001: ID 1d6b:0002
Bus 002 Device 001: ID 1d6b:0001

(2)在开发板中创建 /etc/Wireless/RT2870STA 文件夹，把驱动源文件下的 RT2870STA.dat 复制到开发板的这个文件夹中

 mkdir /etc/Wireless/RT2870STA/ -p

修改：/etc/Wireless/RT2870STA/RT2870STA.dat

    SSID=MT7601AP_WPA  //这里的名字是在pc机上看到的连接ssid名
    AuthMode=WPA2PSK  //认证方式
    EncrypType=TKIP;AES  //加密方式
    WPAPSK=1234567890  //这个是密码

装载驱动：insmod mt7601Usta.ko

启动网卡： ifconfig wlan0 up

ifconfig -a

wlan0     Link encap:Ethernet  HWaddr 0E:4B:88:00:87:9D  
          UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1
          RX packets:165 errors:0 dropped:0 overruns:0 frame:0
          TX packets:0 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:1000 
          RX bytes:40386 (39.4 KiB)  TX bytes:0 (0.0 B)

3. 移植 wpa_supplicant 和 openssl

1 源码下载
(1)wpa_supplicant http://hostap.epitest.fi/wpa_supplicant/ 和 https://w1.fi/releases/
(2)openssl ftp://ftp.openssl.org/source/old/0.9.x/

打补丁：

cp wpa_supplicant-2.5/patches/openssl-0.9.8za-tls-extensions.patch ./openssl-0.9.8za

2 编译openssl

进入openssl路径：打补丁

/openssl-0.9.8za$ patch -p1 < openssl-0.9.8za-tls-extensions.patch
patching file ssl/s3_clnt.c
patching file ssl/s3_srvr.c
patching file ssl/ssl_err.c
patching file ssl/ssl.h
patching file ssl/ssl_sess.c
patching file ssl/t1_lib.c
patching file ssl/tls1.h
patching file util/ssleay.num

开始配置

        #cd openssl-0.9.8e
        #mkdir /home/liu/ARM/test/openssl-0.9.8za/tmp_ssl
        #vim Makefile
                CC= arm-linux-gcc
                AR= arm-linux-ar $(ARFLAGS) r
                RANLIB= arm-linux-ranlib
                INSTALLTOP=/home/liu/ARM/test/openssl-0.9.8za/tmp_ssl
                OPENSSLDIR=/home/liu/ARM/test/openssl-0.9.8za/tmp_ssl
        #make 
        #make install  //执行这一步可能会出错，说什么/usr/bin/pod2man错误，只要删除这个文件就好了

出错1：

smime.pod around line 272: Expected text after =item, not a number
smime.pod around line 276: Expected text after =item, not a number
smime.pod around line 280: Expected text after =item, not a number
smime.pod around line 285: Expected text after =item, not a number
smime.pod around line 289: Expected text after =item, not a number
POD document had syntax errors at /usr/bin/pod2man line 68.
Makefile:686: recipe for target 'install_docs' failed
make: *** [install_docs] Error 1

原因：OpenSSL 与 perl版本不兼容
解决方法：rm -f /usr/bin/pod2man

再次：make install

在/home/liu/ARM/test/openssl-0.9.8za/tmp_ssl目录下安装了ssl库

root@liu-virtual-machine:/home/liu/ARM/test/openssl-0.9.8za/tmp_ssl# ls
bin  certs  include  lib  man  misc  openssl.cnf  private

后面编译 wpa_supplicant 要依赖openssl中的lib和include

3 编译wpa_supplicant

进入wpa_supplicant-0.7.3.tar.gz解压生成的wpa_supplicant-0.7.3/wpa_supplicant目录中：直接在文件中加入这几段命令。

#cp defconfig        .config
#vim .config
    CC=arm-linux-gcc -L/home/liu/ARM/test/openssl-0.9.8za/tmp_ssl/lib/
    CFLAGS += -I/home/liu/ARM/test/openssl-0.9.8za/tmp_ssl/include/
    LIBS += -L/home/liu/ARM/test/openssl-0.9.8za/tmp_ssl/lib/
#make

出错1：

driver_nl80211.c:17:31: fatal error: netlink/genl/genl.h

进入wpa_supplicant目录下.config
将CONFIG_DRIVER_NL80211=y 注释掉即可

继续make，生成wpa_supplicant和wpa_cli后整个移植成功完成

wpa_supplicant是核心程序，它和wpa_cli的关系就是服务和客户端的关系：后台运行wpa_supplicant，使用wpa_cli来搜索、设置、和连接网络。

4 配置wpa_supplicant

(1)首先拷贝wpa_supplicant和wpa-psk-tkip.conf到开发板根文件系统中

cp wpa_cli /home/liu/ARM/rootfs/rootfs2/bin/
cp wpa_supplicant /home/liu/ARM/rootfs/rootfs2/bin/
cp wpa_cli wpa_passphrase /home/liu/ARM/rootfs/rootfs2/bin/
cp examples/wpa-psk-tkip.conf  /home/liu/ARM/rootfs/rootfs2/etc/wpa_supplicant.conf （更改文件名）

(2)设置配置文件

# WPA-PSK/TKIP

ctrl_interface=/var/run/wpa_supplicant

network={
    ssid="vivo Y51A"  #热点的ssid
    scan_ssid=1
    key_mgmt=WPA-EAP WPA-PSK IEEE8021X NONE
    pairwise=TKIP CCMP
    group=CCMP TKIP WEP104 WEP40
    psk="zaq852xsw"  #密码
}

由于WiFi运行要一个运行文件，因此要创建一个文件：

mkdir  -p     /var/run/wpa_supplicant

然后：分配IP地址

• PC：192.168.43.110
• 开发板：192.168.43.2
• 路由器：192.168.43.1

insmod mt7601Usta.ko            //安装驱动程序
ifconfig ra0 up                 //开启无线网卡
ifconfig wlan0 192.168.43.2     //这要根据你的路由器，来设置

ifconfig

wlan0     Link encap:Ethernet  HWaddr 0E:4B:88:00:87:9D  
          inet addr:192.168.0.233  Bcast:192.168.0.255  Mask:255.255.255.0
          UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1
          RX packets:492 errors:0 dropped:0 overruns:0 frame:0
          TX packets:0 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:1000 
          RX bytes:121403 (118.5 KiB)  TX bytes:0 (0.0 B)

连接网络：同时手机上可以显示已经连接了一个设备

 # wpa_supplicant -Dwext -iwlan0 -c/etc/wpa_supplicant.conf -dd &

 # wpa_cli -i wlan0 status

ping通外网：

route add default gw 192.168.43.1 dev ra0                  //配置网关
ping -I ra0 192.168.43.1               //指定网卡 ra0 ping 网关
ping -I ra0 8.8.8.8                    //ping 外网
ping -I ra0 202.108.22.5           //ping 百度的ip地址
vi /etc/resolv.conf              //配置dns
      nameserver 192.168.43.1  
ping -I ra0 www.baidu.com

ping通PC：要先关闭防火墙

 # ping -Iwlan0 192.168.43.110
PING 192.168.43.110 (192.168.43.110): 56 data bytes

让开发板开机自动连上路由器上网

改/etc/profile及其相关文件

cd /tmp
insmod mt7601Usta.ko
ifconfig wlan0 up
mkdir -p /var/run/wpa_supplicant
ifconfig wlan0 192.168.43.2
wpa_supplicant -Dwext -iwlan0 -c/etc/wpa_supplicant.conf -dd &
route add default gw 192.168.43.1 dev wlan0

测试用例

(1)ORTP版本的sample，common/sample_common_venc.c中，修改LOCAL_HOST_IP为192.168.43.110
(2)make clean，make
(3)复制得到的sample_venc到/home/aston/rootfs中

运行结果：

4 设置动态DHCP分配IP地址

动态主机设置协议（Dynamic Host Configuration Protocol, DHCP）是一个局域网的网络协议，使用UDP协议工作，主要有两个用途：
1.给内部网络或网络服务供应商自动分配IP地址
2.给用户给内部网络管理员作为对所有计算机作中央管理的手段。

方法一：dhclient

可以参考：https://www.jb51.net/article/37379.htm

方法二：udhcpc

udhcpc是一个面向嵌入式系统的非常小的DHCP客户端，字母的缩写微- DHCP -客户端（μDHCPc）。

1.udhcpc -i wlan0
udhcpc只是获取一个IP，我们需要把\busybox-1.1.2\examples\udhcp下的脚本simple.script改名为default.script，放在开发板上的/usr/share/dhcpc/目录下，才能将获取的IP写到指定的网卡中。

default.script 依赖于 sample.bound sample.deconfig

所以：复制\busybox-1.1.2\examples\udhcp下的sample.bound sample.deconfig到/usr/share/dhcpc/

由于这两个文件又依赖于/etc/udhcpc/resolv.conf

所以：复制/busybox-1.1.2examples/var_service/fw/etc/resolv.conf 到 /etc/udhcpc/

最后：

# udhcpc -i wlan0
udhcpc (v1.20.2) started

adding dns 192.168.43.1


# ifconfig

64 bytes from 192.168.43.110: seq=2 ttl=128 time=2.764 ms

最后修改 /etc/profile 开机自启动生成 IP 地址

cd /tmp
insmod mt7601Usta.ko
ifconfig wlan0 up
mkdir -p /var/run/wpa_supplicant
ifconfig wlan0 192.168.43.2
wpa_supplicant -Dwext -iwlan0 -c/etc/wpa_supplicant.conf -dd &
route add default gw 192.168.43.1 dev wlan0
udhcpc -i wlan0  #动态获得IP
