5、XR829驱动的整合

将全志给的linux4.9的驱动放到lichee\linux-4.9\drivers\net\wireless\xr829这个目录，修改
lichee\linux-4.9\drivers\net\wireless\Makefile
lichee\linux-4.9\drivers\net\wireless\Kconfig
这两个文件，注意跟公版XR819模块的兼容，如下：

lichee\linux-4.9\drivers\net\wireless\Kconfig

...............................

6、android平台OS的配置

android\device\softwinner\k23x3-wb\BoardConfig.mk
BOARD_WIFI_VENDOR := xradio
##BOARD_WIFI_VENDOR := QCOM
..............................
#1.4 xradio wifi config
ifeq ($(BOARD_WIFI_VENDOR), xradio)# WiFi ConfigurationWPA_SUPPLICANT_VERSION := VER_0_8_XBOARD_WPA_SUPPLICANT_DRIVER := NL80211BOARD_WPA_SUPPLICANT_PRIVATE_LIB := lib_driver_cmd_xrBOARD_HOSTAPD_DRIVER        := NL80211BOARD_HOSTAPD_PRIVATE_LIB   := lib_driver_cmd_xrBOARD_WLAN_DEVICE           := xradioWIFI_DRIVER_MODULE_PATH     := "/system/vendor/modules/xradio_wlan.ko"WIFI_DRIVER_MODULE_NAME     := "xradio_wlan"WIFI_DRIVER_MODULE_ARG      := ""include hardware/xradio/wlan/kernel-firmware/xradio-wlan.mk
endif
其它涉及到的文件：
device\softwinner\common\init.wireless.xradio.rc
android\hardware\xradio\
直接使用全志发布的公版代码即可。

以上的文件修改之后，编译整个系统，系统启动后打开WIFI基本就OK了。

二、BT部分的调试

1、android os平台部分的配置

android\device\softwinner\common\init.wireless.xradio.rc
在文件中添加：# to observe dnsmasq.leases file for dhcp information of soft ap.chown dhcp system /data/misc/dhcp#for XR829 by zhjr add#setprop persist.sys.i2s 1setprop persist.bt.sco.uart  1  //蓝牙电话走串口chmod 0666 /sys/class/bt_power/power_statechmod 0666 /sys/class/bt_power/uart_enable#end by zhaojrandroid\device\softwinner\k23x3-wb\BoardConfig.mk
修改：
BOARD_WIFI_VENDOR := xradio
##BOARD_WIFI_VENDOR := QCOM
..................................
#1.4 xradio wifi config
ifeq ($(BOARD_WIFI_VENDOR), xradio)# WiFi ConfigurationWPA_SUPPLICANT_VERSION := VER_0_8_XBOARD_WPA_SUPPLICANT_DRIVER := NL80211BOARD_WPA_SUPPLICANT_PRIVATE_LIB := lib_driver_cmd_xrBOARD_HOSTAPD_DRIVER        := NL80211BOARD_HOSTAPD_PRIVATE_LIB   := lib_driver_cmd_xrBOARD_WLAN_DEVICE           := xradioWIFI_DRIVER_MODULE_PATH     := "/system/vendor/modules/xradio_wlan.ko"WIFI_DRIVER_MODULE_NAME     := "xradio_wlan"WIFI_DRIVER_MODULE_ARG      := ""include hardware/xradio/wlan/kernel-firmware/xradio-wlan.mk
endif
其他部分已经在WIFI中配置OK.固件部分配置：
android\hardware\xradio\wlan\kernel-firmware\xradio-wlan.mk 添加：
hardware/xradio/wlan/kernel-firmware/boot_xr829.bin:$(TARGET_COPY_OUT_VENDOR)/etc/firmware/boot_xr829.bin \hardware/xradio/wlan/kernel-firmware/fw_xr829.bin:$(TARGET_COPY_OUT_VENDOR)/etc/firmware/fw_xr829.bin \hardware/xradio/wlan/kernel-firmware/sdd_xr829.bin:$(TARGET_COPY_OUT_VENDOR)/etc/firmware/sdd_xr829.bin \hardware/xradio/wlan/kernel-firmware/etf_xr829.bin:$(TARGET_COPY_OUT_VENDOR)/etc/firmware/etf_xr829.bin \hardware/xradio/wlan/kernel-firmware/fw_xr829_bt.bin:$(TARGET_COPY_OUT_VENDOR)/etc/firmware/fw_xr829_bt.bin \hardware/xradio/wlan/kernel-firmware/fw_xr829_bt_sco_hci_uart.bin:$(TARGET_COPY_OUT_VENDOR)/etc/firmware/fw_xr829_bt_sco_hci_uart.bin \hardware/xradio/wlan/kernel-firmware/fw_xr829_bt.bin:/system/etc/firmware/fw_xr829_bt.bin  \hardware/xradio/wlan/kernel-firmware/fw_xr829_bt_sco_hci_uart.bin:/system/etc/firmware/fw_xr829_bt_sco_hci_uart.bin //这个主要针对bt声音通道的固件

2、内核部分的配置修改：

lichee\linux-4.9\arch\arm\configs\sun8iw17p1_android_k23x3-wb_defconfig
添加以下配置：CONFIG_WLAN=y

3、系统部分的配置和上电时序

3.1系统配置

lichee\tools\pack\chips\sun8iw17p1\configs\k23x3-wb\sys_config.fex
bt模块的管脚配置（请结合原理图来配置）：
;--------------------------------------------------------------------------------
;bluetooth configuration
;bt_used:           0- no used, 1- used
;clocks:            external low power clock input (32.768KHz)
;bt_power:          input supply voltage
;bt_io_regulator:   bluetooth I/O voltage
;bt_rst_n:          power up/down internal regulators used by BT section
;--------------------------------------------------------------------------------
[bt]
bt_used             = 1
compatible = "allwinner,sunxi-bt"
bt_power            = "vcc-ctp"
;clocks             = 0x55
bt_rst_n            = port:PL07<1><default><default><0>
ap_wakeup_bt        = port:PL06<1><default><1><0>
音频的I2S1的PCM通道不要配置，保留速鼎模块的配置即可，最后XR829模块不用I2S1的PCM通道，走的是串口到主芯片，然后根据切源管理之后到声卡0到MCU的方式出声音(包括蓝牙电话和音乐)

3.2、上电时序

最后将蓝牙协议栈供应商给的gocsdk放到/system/bin下，如下：

adb push gocsdk /system/bin/
adb shell
chmod 777 /system/bin/gocsdk
sync
之后重新上电即可

系统起来之后，到蓝牙电话界面打开，手机连接车机即可，之后打开WIFI连接到路由器，进行协议栈的注册授权，之后就可以使用蓝牙音乐和蓝牙电话了，注意授权只在第一次刷机之后运行的情况，没有刷机是不需要每次都授权的。
