本章节讲解如何在 Luban-Lite 系统中配置 SDIO 接口的 AIC8800 无线网络模块。
配置 SDMC 接口和 WiFi 模组
使用 SDMC 接口前，选中对应的 SDMC 接口，以 KunLun Pi 开发板为例。
- 使用
scons--meunconfig命令，配置下列内容：Board options [*] Using SDMC0 # 硬件连接哪个 SDMC 接口，选择哪个 SDMC -*- Enable the interrupt of SDMC SDMC0 Parameter ---> Select SDMC0 BUSWIDTH (sdmc 4-bit mode) ---> [ ] Using SDcard hotplug detection (NEW) [*] SDMC0 connect to a SDIO device (3) SDMC0 driver phase (NEW) (0) SDMC0 sample phase (NEW) (40000000) SDMC0 CMU clock frequency (NEW) # 建议使用 40Mhz [*] Using Wireless lan ---> [*] Using Realtek wlan driver ---> [*] AIC8800 wlan driver ---> Wlan0 Parameter ---> Select AIC8800 MODEL (select AIC8800D40L) ---> (PD.7) aic8800 wlan0 power on gpio () aic8800 wlan0 reset gpio # Kunlun Pi WiFi 接口没有连接 reset 引脚，故不做设定 - 在 pinmux.c 中配置 WiFi
模块所需使用的引脚：
struct aic_pinmux aic_pinmux_config[] = { ... #ifdef AIC_WIRELESS_LAN {1, PIN_PULL_DIS, 3, AIC_DEV_AIC8800_WLAN0_PWR_GPIO}, // WIFI_PWR_ON {1, PIN_PULL_DIS, 3, AIC_DEV_AIC8800_WLAN0_RST_GPIO}, // WIFI_RST_ON #endif ... };

测试命令
完成所有配置后，保存退出，编译、烧录。待系统启动后，可执行如下命令进行验证：
wifi -d mode sta wlan0 wifi join SSID PASSWORD // 连接 wifi ping 192.168.1.1 // 假设网关 IP 为 192.168.1.1，ping 一下验证通路
