修改内核配置，开启无线连接

$ pwd
/home/marsa/hi3798mv/HiSTBLinuxV100R005C00SPC060
$ source env.sh
$ make linux-menuconfig

内核配置打开WIFI，确保CFG80211编入内核
请添加图片描述

添加WIFI驱动

修改SDK配置，添加驱动

板载的WiFi模块的驱动在SDK中可以找到，无需再手动添加驱动。

ubuntu:~/hi3798mv/HiSTBLinuxV100R005C00SPC050$ make menuconfig

打开RTL8188ETV驱动，并设置STA模式
配置路径在Linux(REE) System —>Features —>WiFi Support —> 在这里插入图片描述

构建内核、驱动

$ pwd
/home/marsa/hi3798mv/HiSTBLinuxV100R005C00SPC060
$ make linux -j16

构建输出的内核以及驱动路径如下

/home/marsa/hi3798mv/HiSTBLinuxV100R005C00SPC060/out/hi3798mv100/hi3798mdmo1f/image/emmc_image/hi_kernel.bin
/home/marsa/hi3798mv/HiSTBLinuxV100R005C00SPC060/out/hi3798mv100/hi3798mdmo1f/kmod/rtl8188eu.ko

将新的内核镜像烧入机顶盒，rtl8188eu.ko驱动拷贝到机顶盒根文件系统

连接WIFI

ps：这里有个问题没弄清楚，只有一个无线模块，但是显示了两个无线网络接口，网上查了资料可能是虚拟接口啥的，先不管了

安装rtl8188eu.ko驱动，查看wifi网卡

可能是WIFI，有线双网卡的原因，当连接上wifi后虽然无线网卡显示获取到了ip，但是用无线网卡的ip地址连接SSH会失败
拔下网线重启网络服务后就可以通过WIFI连接到hi3798mv100板子了
