加载与功能验证

加载

编译烧录程序，Luban 开机脚本默认自动加载 ko 文件，所以上电后会默认自动加载 aic8800 相关驱动。

lsmod

Module                  Size  Used by    Not tainted

STA 模式测试

网络连接。
本文使用 wpa_supplicant 工具进行测试。先将 WiFi 信息写入 wpa_supplicant.conf 文件，然后用工具加入 WiFi，这是基于已知 WiFi 账号密码的情况下进行测试。更多 wpa_supplicant 工具使用方法，请查阅官方相关文档。
```
touch /tmp/wpa_supplicant.conf
wpa_passphrase my-test 12345678 > /tmp/wpa_supplicant.conf
wpa_supplicant -B -d -i wlan0 -c /tmp/wpa_supplicant.conf
udhcpc -i wlan0
```

网络通信测试。

执行完上述命令后，可看见路由分配了相应的 IP 地址给开发板。下面我们查看 IP 并测试与路由的通信情况。

AP 模式测试

AP 模式使用 hostapd 工具进行测试。此处提供两个配置文件，udhcpd.conf 与 hostapd.conf，分别用作 DHCP 与 AP 模式配置。

interface wlan0

在开发板中应用配置。

hostapd -B -i wlan0 hostapd.conf
ifconfig wlan0 192.168.1.1
udhcpd dhcpd.conf

使用其他 PC 或者开发板连接生成的热点，然后使用 iperf3 进行网络测试。
