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

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

3.2 Build And Compile

make BOARD_TYPE=cus12-9  IF_TYPE=SDIO

3.3 .KO

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

3.4 FW install

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

3.5 Insmod KO

      sh  wlan-load.sh    orinsmod $MODULE_PATH/compat.koinsmod $MODULE_PATH/cfg80211.koinsmod $MODULE_PATH/wlan.ko
