rtl8723bu rtl8723du在mstar平台上移植
调试平台为MSTAR芯片的 android 6.0平台，转载请注明出处，谢谢：https://blog.csdn.net/xiangzi10/article/details/83145296
wifi
重点注意：wifi.cfg文件修改一定要使用vim，使用notepad++或其他文本编辑工具很容易格式不对，导致不能启动
1、首先拿到wifi模块厂家的驱动包：
RTL8723BU_WiFi_linux_v5.2.17.1_26947_COEX20180201-6f52.20180307.rar
https://download.csdn.net/download/xiangzi10/10774452 下载页面
rtl8723du WiFi驱动，移植SDK
https://download.csdn.net/download/xiangzi10/10915017 下载页面
mstar的简单说明文档：
https://download.csdn.net/download/xiangzi10/11162108 下载页面
2、将driver文件夹下解压，解压出来的目录拷贝至mstar源码kernel下，vendor\mstar\kernel\linaro\drivers\net\wireless下并更改文件夹名称为rtl8723bu，修改makefile.mk
CONFIG_PLATFORM_I386_PC = n
CONFIG_PLATFORM_MSTAR = y
ifeq ($(CONFIG_PLATFORM_MSTAR), y)
EXTRA_CFLAGS += -DCONFIG_CONCURRENT_MODE
EXTRA_CFLAGS += -DCONFIG_IOCTL_CFG80211 -DRTW_USE_CFG80211_STA_EVENT
EXTRA_CFLAGS += -DCONFIG_LITTLE_ENDIAN
EXTRA_CFLAGS += -DCONFIG_PLATFORM_MSTAR
EXTRA_CFLAGS += -DCONFIG_PLATFORM_MSTAR_HIGH
ifeq ($(CONFIG_USB_HCI), y)
EXTRA_CFLAGS += -DCONFIG_USE_USB_BUFFER_ALLOC_TX -DCONFIG_FIX_NR_BULKIN_BUFFER
endif
ARCH:=$(R_ARCH)
CROSS_COMPILE:= $(R_CROSS_COMPILE)
KVER:= 3.10.86
KSRC:= $(KERNEL_BUILD_PATH)
MODULE_NAME := 8723bu
endif
修改drivers\net\wireless的makefile.mk，增加
obj-$(CONFIG_RTL8723BU) += rtl8723bu/
修改Kconfig，增加：
source "drivers/net/wireless/rtl8723bu/Kconfig"
make menuconfig
3、编译kernel，发生编译错误：
*** No rule to make target ` /hal/phydm/phydm.mk
修改rel8723bu文件夹下的makefile.mk：
export TopDIR ?= $(shell pwd)修改为
export TopDIR ?= $(shell pwd)/drivers/net/wireless/rtl8723bu
编译成功
4、insmod 8723bu.ko 错误
root@almond:/system/lib/modules # insmod 8723bu.ko
[21073.743551] 8723bu: Unknown symbol wiphy_register (err 0)

[21073.798477] 8723bu: Unknown symbol cfg80211_del_sta (err 0)
这个是没有先安装cfg80211.ko导致的。
先 insmod cfg80211.ko,再 insmod 8723bu.ko后，
5、使用iw命令手动启动测试wifi模块
# ifconfig wlan0 up
#iwlist wlan0 sacn能扫描出所有网络了，于是我手机设了一个没有密码的wifi热点，用IW去连
#iwconfig wlan0 mode Managed
#iwconfig wlan0 essid "HUAWEI nova"，连上了，但是没有IP，下面不知道怎么弄了
#ifconfig wlan0 192.168.34.123 netmask 255.255.255.0
#ifconfig
wlan0 Link encap:Ethernet HWaddr 8C:18:D9:9E:44:3F

换成路由器的open 设置的wifi

以上问题在于没有IP地址，查看相关文档，修改如下：其实iw命令已经包含 iwconfig，iwlist等这些命令，iw命令更新
#ifconfig wlan0 up
#ifconfig
#iw wlan0 scan
#iw wlan0 connect RD1 此时没有ip
#ifconfig wlan0 192.168.1.156 netmask 255.255.255.0设置IP
#busybox iproute add default via 192.168.1.1 添加网关
#ping 192.168.1.1 OK了
#ping 180.97.33.107 （百度IP）也ok了
接下来就是手动调试wpa_supplicant
#wpa_supplicant -d -iwlan0 -Dnl80211 -c/data/misc/wifi/wpa_supplicant.conf -B&
#wpa_cli -p/var/run/wpa_supplicant scan
Using interface 'wlan0'
Failed to connect to non-global ctrl_ifname: wlan0 error: No such file or directory
原因是 wpa_supplicant.conf 里面设置ctrl_interface=/var/run/wpa_supplicant
但是/var目录下没有/var/run/wpa_supplicant
新建一个可以解决此问题
# wpa_cli -p/var/run/wpa_supplicant scan_results
Selected interface 'wlan0'

以上是手动调试用来确认驱动和wpa_supplicant是否正常，以上linux驱动整合OK
修改安卓层，查看android_ref_codes_M_6.x文件夹里的文件进行安卓整合：
1、device/mstar/XXX 的目录下device.mk添加：
BOARD_WIFI_VENDOR := realtek
ifeq ($(BOARD_WIFI_VENDOR), realtek)
WPA_SUPPLICANT_VERSION := VER_0_8_X
BOARD_WPA_SUPPLICANT_DRIVER := NL80211
BOARD_WPA_SUPPLICANT_PRIVATE_LIB := lib_driver_cmd_rtl

else

BOARD_HOSTAPD_PRIVATE_LIB := lib_driver_cmd_bcmdhd
BOARD_WLAN_DEVICE := bcmdhd
endif
ifeq ($(BOARD_WIFI_VENDOR), realtek)
####rtl8723bu

endif
####rtl8723bu
2、去掉其他地方关于wifi的配置BoardConfig.mk，BoardConfigCommon.mk
3、修改init.xxx.rc
service rtw_fwloader /system/bin/rtw_fwloader
class main
disabled
oneshot
######## supplicant patch to startSupplicant #########

######## Realtek wifi patch ####################
p2p_supplicant wpa_supplicant的service不需要添加，因为mstar方案已经将此整合到startSupplicant里面去了
PRODUCT_PROPERTY_OVERRIDES += \
wifi.interface=wlan0
此原文件已有，无需添加
按文档修改ANDROID_SDK/device/ti/panda/overlay/frameworks/base/core/res/res/values/config.xml
使用mstar原有的supplicant
3、device/msar/xxx的 preinstall\preinstall.mk添加
$(LOCAL_PATH)/modules/8723bu.ko:system/lib/modules/8723bu.ko
4、修改preinstall\wifi\wifi.cfg
=====
wifi_vendor_name=RTL8723BU
order=1
count_vid_pid=1
vid_pid=0x0bda:0xb720
sta=1
softap=1
p2p=1
5、修改device\mstar\common\preinstall\wifi下wifi_load_apdriver.sh，wifi_load_driver.sh，wifi_unload_apdriver.sh，wifi_unload_driver.sh，startSupplicant.sh ，修改device\mstar\common\preinstall\preinstall.mk
6、编译AN，报错
make: *** No rule to make target `out/target/product/bennet/obj/STATIC_LIBRARIES/lib_driver_cmd_rtl_intermediates/export_includes', needed by `out/target/product/bennet/obj/EXECUTABLES/hostapd_intermediates/import_includes'. Stop.
7、拷贝wlan到hardware\realtek\wlan
8、再次编译，无错误。升级完成后wifi可用。
蓝牙：
蓝牙移植包下载：https://download.csdn.net/download/xiangzi10/10774468
1、拷贝驱动文件至kernel/drivers/bluetooth/
修改linaro\drivers\bluetooth\Makefile添加
obj-$(CONFIG_BT_RTKBTUSB) += rtk_btusb.o
修改linaro\drivers\bluetooth\Kconfig添加
config BT_RTKBTUSB
tristate "RTK HCI USB driver"
depends on USB
help
RTK Bluetooth HCI USB driver
执行make menuconfig
编译生成rtk_btusb.ko
2、device\mstar\common\sepolicy相关文件修改，依据文档
3、将模块厂家的包rtkbt整合进hardware\realtek\bt
4、修改device\mstar\xxx\ueventd.mainz.rc
/dev/rtk_btusb 0666 bluetooth net_bt_stack
5、修改init.xxx.rc
######rtk_bt
# bluetooth
# change back to bluetooth from system
chown bluetooth net_bt_stack /data/misc/bluetooth
mkdir /data/misc/bluedroid 0777 bluetooth net_bt_stack

####rtk_bt
6、编译升级后蓝牙可用
移植中问题点：
1、打不开蓝牙，lsmod 发现没有加载rtk_btusb.ko，打印logcat，如下：

查找libbluedroid，发现bluetooth.c文件里有pid，vid数组，添加相应的模块id，
static struct bt_vid_pid rtk_tables[] =
{
{0x0bda,0x818c},//RTL8761AW bt + 8192EU wifi combo
{0x0bda,0xb761},//RTL8761AUV bt only
{0x0bda,0xb720},//RTL8723BU bt + wifi combo
{0x0bda,0xb72a},//RTL8723BU bt + wifi combo
{0x0bda,0xd723},//RTL8723DU bt + wifi combo
{0x0bda,0xc820},//RTL8821CU bt + wifi combo
};重新编译后升级，发现lsmod里出现rtk_btusb
2、lsmod里面有rtk_btusb，但是仍然打不开蓝牙，logcat如上还是有：
BluetoothServiceJni: No Bluetooth Library found
BluetoothSdpJni: Bluetooth module is not loaded
解决办法：
rtkbt里面的要对移植包做些修改，根据mstar的demo来修改。修改完成后测试OK，可以打开蓝牙。
3、蓝牙声音发现有声音变调及声音变快问题，已解决。
