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
[root@rk3399:/]# find . -name *.ko
[root@rk3399:/]# lsmod
Module Size Used by Not tainted
[root@rk3399:/]#
在kernel路径下执行make menuconfig,然后按/输入8822,Ok
Symbol: RTL8822CE [=m] │ │ Type : tristate │ │ Prompt: Realtek 8822C PCIE WiFi │ │ Location: │ │ -> Device Drivers │ │ -> Network device support (NETDEVICES [=y]) │ │ -> Wireless LAN (WLAN [=y]) │ │ -> Rockchip Wireless LAN support (WL_ROCKCHIP [=y]) │ │ (3) -> Realtek Wireless Device Driver Support (RTL_WIRELESS_SOLUTION [=y]) │ │ Defined at drivers/net/wireless/rockchip_wlan/rtl8822ce/Kconfig:1 │ │ Depends on: NETDEVICES [=y] && WLAN [=y] && WL_ROCKCHIP [=y] && RTL_WIRELESS_SOLUTION [=y] && PCI [=y]
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

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;

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(此方法编译时间比较长,而且之前遇到错误还需要重新处理,可以使用下面的方法)

网上也有说如果需要重新编译某个package可以删除.stamp_相关的文件或make clean,如
rkwifibt-1.0.0,rm -rf buildroot/output/rockchip_rk3399_tinkerboard2/build/rkwifibt-1.0.0/.stamp_*
开机自动加载wifi驱动(自动加载的.ko文件是根据./buildroot/package/Config.in配置的BR2_PACKAGE_RKWIFIBT_WIFI_KO属性)
