Step:
1、在linux/drivers/net/wireless/realtek 目录下，git clone https://gitee.com/buyadong/TL-WN722N-V2.git
2、cd TL-WN722N-V2
3、修改Makefile文件
CONFIG_POWER_SAVING = n
CONFIG_PLATFORM_I386_PC = n
# 增加型号
CONFIG_PLATFORM_ARM_SUNIV = y
# 增加编译路径
ifeq ($(CONFIG_PLATFORM_ARM_SUNIV), y)
EXTRA_CFLAGS += -DCONFIG_LITTLE_ENDIAN
EXTRA_CFLAGS += -DCONFIG_PLATFORM_ARM_SUNIV
# default setting for Android 4.1, 4.2
EXTRA_CFLAGS += -DCONFIG_CONCURRENT_MODE
EXTRA_CFLAGS += -DCONFIG_IOCTL_CFG80211 -DRTW_USE_CFG80211_STA_EVENT
EXTRA_CFLAGS += -DDCONFIG_P2P_IPS
EXTRA_CFLAGS += -DCONFIG_PLATFORM_OPS
ifeq ($(CONFIG_USB_HCI), y)
EXTRA_CFLAGS += -DCONFIG_USE_USB_BUFFER_ALLOC_TX
_PLATFORM_FILES += platform/platform_ARM_SUNxI_usb.o
endif
ifeq ($(CONFIG_SDIO_HCI), y)
# default setting for A10-EVB mmc0
#EXTRA_CFLAGS += -DCONFIG_WITS_EVB_V13
_PLATFORM_FILES += platform/platform_ARM_SUNxI_sdio.o
endif
ARCH := arm
CROSS_COMPILE := arm-none-linux-gnueabi-
#CROSS_COMPILE=/home/android_sdk/Allwinner/a10/android-jb42/lichee-jb42/buildroot/output/external-toolchain/bin/arm-none-linux-gnueabi-
KVER := 4.15.0
KSRC:= ../../../../../
#KSRC=/home/android_sdk/Allwinner/a10/android-jb42/lichee-jb42/linux-3.0
endif
4、修改TL-WN722N-V2/platform/platform_ARM_SUNxI_usb.c
//#include <mach/sys_config.h>
5、修改realtek目录下Kconfig，增加一行 source "drivers/net/wireless/realtek/TL-WN722N-V2/Kconfig"
6、修改realtek目录下Makefile，增加一行 obj-$(CONFIG_RTL8188EU) += TL-WN722N-V2/
7、配置kernel的menuconfig : make CROSS_COMPILE=arm-linux-gnueabi- ARCH=arm menuconfig
[ * ] Device Drivers ---> [ * ] Network device Support ---> [ * ] Wireless LAN ---> [ * ] Realtek devices ---> <M> Realtek 8188E USB Wifi
8、编译 make CROSS_COMPILE=arm-linux-gnueabi- ARCH=arm -j4
9、拷贝TL-WN722N-V2文件中 8188eu.ko文件到nano，并加载.
======================================================================
不知道怎么回事，我加载了8188eu之后，内核会崩溃

[ 35.776845] Kernel panic - not syncing: Fatal exception in interrupt
[ 35.791052] Rebooting in 5 seconds..看第二个问题：
inline u32 rtw_get_on_cur_ch_time(_adapter *adapter)
{
if (adapter->mlmeextpriv.cur_channel == adapter_to_dvobj(adapter)->oper_channel)
return adapter_to_dvobj(adapter)->on_oper_ch_time;
else
return 0;
}
主要是adapter_to_dvobj(adapter) 也就是 adapter->dvobj 是空指针，导致出错，但是如果加上判断 if (adapter_to_dvobj(adapter) == NULL) return 0; 就会包mod_timer那里空指针。 搞不定了
