BuildRoot配置RTL8822CE WIFI&BT模块（WIFI部分）

zoipuus2024-01-14 22:28

TinkerBoard2主板自带的无线模块为RTL8822CE，PCIe接口

之前在风火轮下载的Linux源码编译出来的BuildRoot根文件系统没有相关的驱动文件

Lua 复制代码 
[root@rk3399:/]# find . -name *.ko
[root@rk3399:/]# lsmod
Module                  Size  Used by    Not tainted

1、配置无线网卡驱动

在kernel路径下执行make menuconfig，然后按/输入8822，Ok

确认配置没问题，RTL8822CE编译成模块，其他配置都有打开

在8822ce源码目录也确实编译了8822ce.ko驱动文件，但是打包的时候没有拷贝

在Linux_SDK源码目录下执行make menuconfig，没有8822CE选择，而且wifi chip默认选择AWCM256，导致BR2_PACKAGE_RKWIFIBT_VENDOR的值为CYPRESS

Lua 复制代码

修改./buildroot/package/Config.in，添加RTL8822CE模块，并在make menuconfig里面选中

添加以下四个package

  • iw: 可用于OPEN、WEP这两种"认证/加密"，以及扫描WIFI热点等；

  • wpa_supplicant: 可用于前面4种"认证/加密"；

  • hostapd: 能够使得无线网卡切换为AP模式；

  • dhcp: STA模式使WIFI网卡动态获取IP，AP模式分配IP；

3、使用dhclient配置

执行wifi_start.sh连接网络后可以使用dhclient自动配置IP地址和DNS

[root@rk3399:/]# ifconfig wlp1s0

wifi_start.sh改为

bash 复制代码 
#!/bin/sh
WIFISSID=$1
WIFIPWD=$2
CONF=/tmp/wpa_supplicant.conf

cp /etc/wpa_supplicant.conf /tmp/
echo "connect to WiFi ssid: $WIFISSID, Passwd: $WIFIPWD"
sed -i "s/SSID/$WIFISSID/g" $CONF
sed -i "s/PASSWORD/$WIFIPWD/g" $CONF
killall wpa_supplicant
sleep 1
wpa_supplicant -B -i wlp1s0 -c $CONF
sleep 5
dhclient wlp1s0

4、编译时自动拷贝8822ce.ko

修改./buildroot/package/rockchip/rkwifibt/rkwifibt.mk，编译buildroot时就可以拷贝8822ce.ko到buildroot/output/rockchip_rk3399_tinkerboard2/target/system/lib/modules/8822ce.ko，我是执行rm -rf ./buildroot/output/后再编译buildroot的

diff 复制代码 
diff --git a/package/rockchip/rkwifibt/rkwifibt.mk b/package/rockchip/rkwifibt/rkwifibt.mk
index b50465df..aab7637a 100644

     -$(INSTALL) -D -m 0755 $(@D)/$(SXLOAD_WIFI) $(TARGET_DIR)/etc/init.d/

网上也有说如果需要重新编译某个package可以删除.stamp_相关的文件，如rkwifibt-1.0.0，rm -rf buildroot/output/rockchip_rk3399_tinkerboard2/build/rkwifibt-1.0.0/.stamp_*

或者执行make clean

开机自动加载wifi驱动
