三、设置开机启动

开发板：荔枝派zero dock
linux：5.2.y
rootfs：buildroot 2020.02.04

参考：https://blog.csdn.net/xiangkezhi167810/article/details/111564192

一、配置Linux内核

1、配置RTL8762

Linux 内核配置里面使能编译成模块，编译后的.ko驱动文件在drivers/staging/rtl8723bs目录下：

将r8723bs.ko驱动模块文件拷贝到根文件系统的/lib/moduel
将WiFi固件rtl8723bs_nic.bin拷到根文件系统分区/lib/firmware/rtlwifi目录下

在这里插入图片描述

2、配置Wireless

make ARCH=arm menuconfig

配置Networking support
配置Wireless
配置cfg80211 - wireless configuration API
配置Generic IEEE 802.11 Networking Stack (mac80211)

在这里插入图片描述

Networking support ----->
 Wireless--------->

二、加载模块


# insmod r8723bs.ko
[   36.481676] r8723bs: module is from the staging directory, the quality is unknown, you have been warned.
[   36.511062] RTL8723BS: module init start
[   36.515010] RTL8723BS: rtl8723bs v4.3.5.5_12290.20140916_BTCOEX20140507-4E40
[   36.522154] RTL8723BS: rtl8723bs BT-Coex version = BTCOEX20140507-4E40
[   36.530386] pnetdev = 962276c2
[   36.566061] RTL8723BS: rtw_ndev_init(wlan0)
[   36.574579] RTL8723BS: module init ret =0
# [   36.668467] rtl8723bs: acquire FW from file:rtlwifi/rtl8723bs_nic.bin
[   36.676667] rtl8723bs mmc1:0001:1: Direct firmware load for rtlwifi/rtl8723bs_nic.bin failed with error -2
[   36.686451] Request firmware failed with error 0xfffffffe

2.1 缺固件

在根文件系统里面新建一个文件夹：mkdir /lib/firmware/rtlwifi
将rtl8723bs_nic.bin文件拷贝进去
再次加载模块，OK啦！

# insmod /lib/modules/r8723bs.ko
[   18.907777] r8723bs: module is from the staging directory, the quality is unknown, you have been warned.
[   18.936518] RTL8723BS: module init start
[   18.940558] RTL8723BS: rtl8723bs v4.3.5.5_12290.20140916_BTCOEX20140507-4E40
[   18.947601] RTL8723BS: rtl8723bs BT-Coex version = BTCOEX20140507-4E40
[   18.956571] pnetdev = (ptrval)
[   18.997777] RTL8723BS: rtw_ndev_init(wlan0)
[   19.006120] RTL8723BS: module init ret =0
# [   19.099402] rtl8723bs: acquire FW from file:rtlwifi/rtl8723bs_nic.bin
[   19.206303] random: crng init done
[   19.209732] random: 3 urandom warning(s) missed due to ratelimiting

2.2 打开wlan0

# ifconfig wlan0 up
# ifconfig
lo        Link encap:Local Loopback
          inet addr:127.0.0.1  Mask:255.0.0.0
          UP LOOPBACK RUNNING  MTU:65536  Metric:1
          RX packets:64 errors:0 dropped:0 overruns:0 frame:0
          TX packets:64 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:1000
          RX bytes:4736 (4.6 KiB)  TX bytes:4736 (4.6 KiB)

wlan0     Link encap:Ethernet  HWaddr 84:20:96:AB:33:12
          UP BROADCAST MULTICAST  MTU:1500  Metric:1
          RX packets:0 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:0 (0.0 B)  TX bytes:0 (0.0 B)

2.3 配置连接WiFi

编辑vi /etc/network/interfaces文件

# Configure Loopback
auto lo
iface lo inet loopback
# wlan0
auto wlan0
iface wlan0 inet dhcp

wpa_supplicant连接WIFI的时候会从配置文件中读取账号和密码，以及加密方式等，所以我们再运行wpa_supplicant工具的时候要提前写好配置文件。
配置文件名称自定，但是要以 .conf 为后缀，并保存在 /etc/ 目录下，这边给出一个配置文件的例子。
编辑vi /etc/wpa_supplicant.conf 文件:

ctrl_interface=/var/run/wpa_supplicant
ctrl_interface_group=0
ap_scan=1
network={
    ssid="KKKK"
    scan_ssid=1
    key_mgmt=WPA-EAP WPA-PSK IEEE8021X NONE
    pairwise=TKIP CCMP
    group=CCMP TKIP WEP104 WEP40
    psk="99999999"
    priority=5
}

创建一个socket通信的目录

mkdir -p /var/run/wpa_supplicant

连接WiFi

wpa_supplicant -B -c /etc/wpa_supplicant.conf -i wlan0

连接上WiFi了！

# wpa_supplicant -B -c /etc/wpa_supplicant.conf -i wlan0
Successfully initialized wpa_supplicant
rfkill: Cannot open RFKILL control device
# [  551.186574] RTL8723BS: rtw_set_802_11_connect(wlan0)  fw_state = 0x00000008

[  551.969865] RTL8723BS: set group key camid:5, addr:c8:e7:d8:34:27:84, kid:1, type:AES

获取IP地址–配置DHCP

# udhcpc -i wlan0
udhcpc: started, v1.31.1
udhcpc: sending discover
udhcpc: sending select for 192.168.1.108
udhcpc: lease of 192.168.1.108 obtained, lease time 7200
deleting routers
adding dns 202.96.134.33
adding dns 202.96.128.68

查看网络状态

# wpa_cli -iwlan0 status
bssid=c8:e7:d8:34:27:84
freq=2437
ssid=MERCURY_2784
id=0
mode=station
pairwise_cipher=CCMP
group_cipher=CCMP
key_mgmt=WPA2-PSK
wpa_state=COMPLETED
ip_address=192.168.1.108
address=84:20:96:ab:33:12
uuid=7574b47e-48e1-5457-ab19-3a4cde3b2130

ping功能测试

# ping www.baidu.com
PING www.baidu.com (14.215.177.38): 56 data bytes

非常nice !

三、设置开机启动

新建一个rc.local文件到/etv/init.d目录下

# vi /etc/init.d/rc.local

内容：

!/bin/sh

sh /etc/init.d/auto_wifi_link.sh
echo "wifi finish!!"

创建脚本auto_wifi_link.sh放到/etc/init.d/目录下

# vi /etc/init.d/auto_wifi_link.sh

内容：

#!/bin/sh
insmod /lib/modules/r8723bs.ko
ifconfig wlan0 up
wpa_supplicant -B -c /etc/wpa_supplicant.conf -i wlan0
sleep 3s
udhcpc -i wlan0

修改开机启动项 vi /etc/inittab
在# now run any rc scripts 后加入如下

::sysinit:/etc/init.d/rc.local

如下：

# /etc/inittab
#
# Copyright (C) 2001 Erik Andersen <andersen@codepoet.org>
#
# Note: BusyBox init doesn't support runlevels.  The runlevels field is
# completely ignored by BusyBox init. If you want runlevels, use
# sysvinit.
#
# Format for each entry: <id>:<runlevels>:<action>:<process>
#
# id        == tty to run on, or empty for /dev/console
# runlevels == ignored
# action    == one of sysinit, respawn, askfirst, wait, and once
# process   == program to run

# Startup the system
::sysinit:/bin/mount -t proc proc /proc
::sysinit:/bin/mount -o remount,rw /
::sysinit:/bin/mkdir -p /dev/pts
::sysinit:/bin/mkdir -p /dev/shm
::sysinit:/bin/mount -a
::sysinit:/bin/hostname -F /etc/hostname
# now run any rc scripts
::sysinit:/etc/init.d/rcS
::sysinit:/etc/init.d/rc.local #看这里！！！！

# Put a getty on the serial port
#console::respawn:/sbin/getty -L  console 0 vt100 # GENERIC_SERIAL
::respawn:-/bin/sh

# Stuff to do for the 3-finger salute
#::ctrlaltdel:/sbin/reboot

# Stuff to do before rebooting
::shutdown:/etc/init.d/rcK
::shutdown:/sbin/swapoff -a
::shutdown:/bin/umount -a -r

修改rc.local 权限

# chmod 755 /etc/init.d/rc.local

rc.local就能够正常工作了。
reboot重启看到自动导入驱动然后连接wifi得到ip地址
