2.4 编译WiFi驱动
2.4.1 获取WiFi源代码
相关EasyMesh源代码，请联系博主。
2.4.2 Linux内核合入驱动头文件
执行如下命令拷贝AIO/drivers/core_tech_modules/目录下对应文件夹中的cnss2.h、qcn_sdio_al.h及cnss_utils.h文件至内核<kernel_path>/include/net/目录下。
$ sudo cp -r AIO/drivers/core_tech_modules/cnss2/cnss2.h <kernel_path>/include/net/
$ sudo cp -r AIO/drivers/core_tech_modules/inc/qcn_sdio_al.h <kernel_path>/include/net/
$ sudo cp -r AIO/drivers/core_tech_modules/cnss_utils/cnss_utils.h <kernel_path>/include/net/
2.4.3 编译WiFi驱动和相关应用代码
执行如下命令进行编译：
$ cd WiFi_EasyMesh/chss_host_LEA/chss_proc/host/AIO/build
$ make CONFIG_ONE_MSI_BUILD=y CONFIG_PERF_BUILD=y
$ make mesh_daemon MAKECMDGOALS=all
$ make mesh_pack
2.5 加载EasyMesh
2.5.1 准备环境
Step 1: 检查PCIe是否枚举成功
$ lspci
若包含如下显示信息，则表示PCIe枚举成功。
02:00.0 Network controller: Qualcomm Device 1103 (rev 01)
Step 2: 编辑/etc/NetworkManager/NetworkManager.conf
[main]
plugins=ifupdown,keyfile,ofono
dns=dnsmasq
[ifupdown]
managed=false
[keyfile]
unmanaged-devices=interface-name:br-lan,interface-name:wlan*
Step 3: 拷贝Wi-Fi固件、配置文件和应用程序
$ sudo mkdir /lib/firmware/wlan
$ sudo cp WiFi_EasyMesh/meta_build/load_meta/wlan_ firmware/* /lib/firmware/
$ sudo cp WiFi_EasyMesh/meta_build/load_meta/BDF&INI/FC64EABMD/bdwlan* /lib/firmware/
$ sudo cp WiFi_EasyMesh/meta_build/load_meta/BDF&INI/FC64EABMD/wlan/qcom_cfg.ini_ map /lib/firmware/wlan/qcom_cfg.ini
$ sudo cp WiFi_EasyMesh/chss_host_LEA/chss_proc/host/AIO/roofs-ve-f10c1.build/sbin/* /sbin
Step 4: 安装EasyMesh应用，修改WiFi_EasyMesh/chss_host_LEA/chss_proc/host/AIO/emesh _pack/emesh_install.sh脚本中的EMESH_PATH变量为绝对路径后，执行脚本。
备注：配置文件qcom_cfg.ini_map适用于MAP Agent模式，而配置文件qcom_cfg.ini适用于默认的STA模式。
