aic8800_netdrv（aic8800_netdrv.ko）和aic8800_usb（aic8800_fdrv.ko和aic_load_fw.ko）是USB接口（受build-usb开关控制）。

aic8800dc（aic8800_bsp.ko、aic8800_btlpm.ko和aic8800_fdrv.ko）是SDIO接口（受build-sdio开关控制）。

 

USB和SDIO两种接口各有一个aic8800_fdrv.ko，两个ko虽然名字是一样的，但是内容是不一样的。

编译的时候两个都编译了，但只复制了SDIO接口的那个aic8800_fdrv.ko，所以insmod就走了SDIO接口，当然就检测不到设备了。

export RK_ENABLE_WIFI=y
export RK_ENABLE_WIFI_CHIP="AIC8800DW_USB"

正常编译出来的以aic8800开头的ko文件应该只有一个：/oem/usr/ko/aic8800_fdrv.ko

 

开机后的模块插入顺序：

就可以成功了。

 

可以用ifconfig看到wlan0接口。

今天发现根本不需要把固件文件复制到/lib/firmware里面，可以直接用/oem/usr/ko/aic_fw里面的bin文件。只要在插入aic_load_fw.ko模块的时候指定aic_fw_path参数就行了。

insmod /oem/usr/ko/cfg80211.ko
insmod /oem/usr/ko/aic_load_fw.ko aic_fw_path=/oem/usr/ko/aic_fw
insmod /oem/usr/ko/aic8800_fdrv.ko

【sysdrv/drv_ko/wifi/insmod_wifi.sh】

把下面的代码删除掉。

#aic8800
if [ -n "$(cat /proc/device-tree/model | grep "W")" ]; then
 insmod cfg80211.ko
 insmod libarc4.ko
 insmod ctr.ko
 insmod ccm.ko
 insmod libaes.ko
 insmod aes_generic.ko
 insmod aic8800_bsp.ko
 sleep 0.2
 insmod aic8800_fdrv.ko
 sleep 2
 insmod aic8800_btlpm.ko
 sleep 0.1
fi

改成

#aic8800
if [ -f /oem/usr/ko/aic8800_fdrv.ko ]
then
 insmod /oem/usr/ko/cfg80211.ko
 insmod /oem/usr/ko/aic_load_fw.ko aic_fw_path=/oem/usr/ko/aic_fw
 insmod /oem/usr/ko/aic8800_fdrv.ko
fi

 

【project/cfg/BoardConfig_IPC/BoardConfig-SPI_NAND-Buildroot-RV1106_Luckfox_Pico_Pro-IPC.mk】

添加下面的内容。

# enable rockchip wifi
export RK_ENABLE_WIFI=y
export RK_ENABLE_WIFI_CHIP=AIC8800DW_USB

# config wifi ssid and passwd
# this will generate /etc/wpa_supplicant.conf
export LF_WIFI_SSID="路由器名称"
export LF_WIFI_PSK="路由器密码"

 

编译镜像，烧录并重启板子后，就能看到板子的wifi已经自动连上热点了，能获取到IP地址，还能ping通百度。
