内核版本 ：linux-4.1.15
交叉编译链：arm-linux-gnueabihf-
文件系统：L4115-fsl-image-qt5-myimx6a7.tar.bz2
WIFI源码：rtl8723BU_WiFi_linux_v5.8.4_33660.20190516_COEX20181129-7272.tar.gz
BT源码：Linux_BT_USB_v3.10_20171108_8723BU_BTCOEX_20171128-6d50.tgz
1.BT
a.解压源码
tar xvf Linux_BT_USB_v3.10_20171108_8723BU_BTCOEX_20171128-6d50.tgz
cd Linux_BT_USB_v3.10_20171108_8723BU_BTCOEX_20171128-6d50/bluetooth_usb_driver
b.设置交叉编译环境变量
export ARCH=armexport CROSS_COMPILE=~/my-work/imx6/4.1/gcc-linaro-5.3-2016.02-x86_64_arm-linux-gnueabihf/bin/arm-linux-gnueabihf-c.修改Makefile
...
KDIR := /home/linyn/my-work/imx6/4.1/wifi/linux-4.1.15
...
d.编译
make -j4
可以看到编译的出的rtk_btusb.ko
e.测试（复制zImage和模块rtk_btusb.ko到板子上）cp rtl8723b_fwrtl8723bu_config /lib/firmware/insmod 8723bu.kohciconfig hci0 up hciconfig hci0 piscan
hciconfig -a
hcitool scan
