RK3566开启wifi自适应

系统:linux(buildroot)

一、修改Makefile,使能RTW_ADAPTIVITY

文件路径:..\x3566_linux_v1.2.0\kernel\drivers\net\wireless\rockchip_wlan\rtl8821cs\Makefile

第74行：

CONFIG_RTW_ADAPTIVITY_EN = disable

改为：

CONFIG_RTW_ADAPTIVITY_EN = enable

二、重新编译内核生成8821cs.ko

cd到sdk目录，执行./build.sh kernel

文件路径:..\x3566_linux_v1.2.0\kernel\drivers\net\wireless\rockchip_wlan\rtl8821cs\8821cs.ko

三、替换终端里的8821cs.ko

设备通过USB线连接到电脑，使用adb push命令推送文件到终端：

先将8821cs.ko拷贝到磁盘A:的根目录下，这样路径短一些。

C:\Users\V505L>adb remount
* daemon not running. starting it now on port 5037 *
* daemon started successfully *
remount failed: SuccessC:\Users\V505L>adb push a:\8821cs.ko /system/lib/modules
1567 KB/s (5332832 bytes in 3.323s)

推送完成之后重启终端。

 四、查看是否安装成功

其中CONFIG_RTW_ADAPTIVITY_EN = 1表明配置生效。
