基于SDIO接口的WIFI，在应用上，功耗低于USB接口，且无须USB Device支持，满足某些应用场景

1 硬件连接

2 Vivado工程配置

3 驱动编译

3.1 KERNRL CONFIG (build ENV) 修改

复制代码

    export KERNELPATH=<path of kernel header>
    export TOOLCHAIN=<path of toolchain>
    export KERNELARCH=arm
    export CROSS_COMPILE=${TOOLCHAIN}/arm-none-linux-gnueabi-
    export TOOLPREFIX=${CROSS_COMPILE}
    # For backports
    export KLIB=${KERNELPATH}
    export KLIB_BUILD=${KERNELPATH}

3.2 Build And Compile

复制代码

make BOARD_TYPE=cus12-9  IF_TYPE=SDIO

3.3 .KO

复制代码

in ~/rootfs-cus12-9.build/lib/modules$

3.4 FW install

复制代码

copy "~/meta_build/load_meta/wlan_firmware"  to  "/lib/firmware"
       cd ~/meta_build/load_meta
       cp -frv wlan_firmware /lib/firmare
copy configuraiton files    to "/lib/firmware/wlan" 
       cd ~/meta_build/load_meta
       cp -frv AIO/rootfs-cus12-9.build/lib/firmware/wlan  /lib/firmare/wlan

3.5 Insmod KO

复制代码

      sh  wlan-load.sh    or
      insmod $MODULE_PATH/compat.ko
      insmod $MODULE_PATH/cfg80211.ko
      insmod $MODULE_PATH/wlan.ko
