全志A33 Android4.4 RTL8723DS WIFI/BT驱动调试

平台:全志A33 Android4.4

模块:RTL8723DS

接口:SDIO、uart1(ttyS1)

kernel:Linux3.4

 

一、 移植8723ds驱动,让驱动参与编译

    1.将rtl8723ds驱动源码放到linux-3.4/drivers/net/wireless/目录下,并生成一个rtl8723ds目录

驱动下载地址:https://download.csdn.net/download/Mrdeath/13744931

注意:该驱动不是原版驱动,而是经过了我的修改去适配了A33 Android4.4的SDK,由于A33源码里面并没有8723ds的源码,所以sys_config.fex,以及rf目录下没有针对8723ds的电源控制,所以如果你是完全参考我方案来移植,请务必使用该版驱动。

    2.修改配置文件添让驱动参与编译:

      (1).修改Kconfig文件

--git a/lichee/linux-3.4/drivers/net/wireless/Kconfig b/lichee/linux-3.4/drivers/net/wireless/Kconfig
index 33409594d0..0055f4567c 100755

+source "drivers/net/wireless/rtl8723ds/Kconfig"
 endif # WLAN

    (2).修改Makefile文件

--git a/lichee/linux-3.4/drivers/net/wireless/Makefile b/lichee/linux-3.4/drivers/net/wireless/Makefile

    (3).menuconfig里勾选rtl8723ds驱动,作为模块编译

 

配置完上面内容后,rtl8723ds驱动就能正确参与编译了。

 

二、 配置系统开机自动加载8723ds驱动

    1.修改BoardConfig.mk

SW_BOARD_USR_WIFI、BOARD_WLAN_DEVICE、SW_BOARD_HAVE_BLUETOOTH_NAME值改为8723ds

diff --git a/android4.4/device/softwinner/astar-y3/BoardConfig.mk b/android4.4/device/softwinner/astar-y3/BoardConfig.mk

      2.修改 hardware/libhardware_legacy/wifi/Android.mk

       3.修改hardware/libhardware_legacy/wifi/wifi.c

index ce32ea4b43..fac4e489c6 100755

     #ifndef WIFI_DRIVER_MODULE_PATH

   将编译后的ko文件添加到android4.4/device/softwinner/astar-y3/modules/modules/目录下。    

   上面添加完之后,系统开机后就能自动加载8723.ko驱动,具体的加载流程我就不描述了。这里简单说下加载ko文件是在hardware/libhardware_legacy/wifi/wifi.c下的int wifi_load_driver() 加载对应的wifi驱动

 

三、添加fw和config固件

   1.修改astar_y3.mk

--- a/android4.4/device/softwinner/astar-y3/astar_y3.mk
+++ b/android4.4/device/softwinner/astar-y3/astar_y3.mk
@@ -71,6 +71,9 @@ PRODUCT_COPY_FILES += \

+
 #rtl8723bs bt fw and config
 $(call inherit-product, hardware/realtek/bluetooth/rtl8723bs/firmware/rtlbtfw_cfg.mk)

   2.将hw_bt_rtl8723ds.tar.gz压缩包解压到hardware/realtek/bluetooth目录下

目录名字重命名为rtl8723ds

 包下载地址:https://download.csdn.net/download/Mrdeath/13745180

注意:如果你的bt使用的接口不是ttyS1,请修改hardware/realtek/bluetooth/rtl8723ds/libbt-vendor/include/vnd_astar-y3.txt文件下的BLUETOOTH_UART_DEVICE_PORT = "/dev/ttyS*"

 

四、配置8723ds参数

1.修改init.sun8i.rc

蓝牙串口改为ttyS1

 diff --git a/android4.4/device/softwinner/astar-y3/init.sun8i.rc b/android4.4/device/softwinner/astar-y3/init.sun8i.rc
index 7a9d9f63f1..df52fac6e0 100755

+     chmod 0666 /dev/ttyS1
+     chown bluetooth net_bt_stack /dev/ttyS1
 #
     # power up/down interface
 	chmod 0660 /sys/class/rfkill/rfkill0/state

2.修改sys_config文件

在[wifi_para]那一栏,我设置的是8723bs的参数,其实这里我是对8723ds的电源管理参考8723bs进行了修改,所以这些参数同样针对8723ds能使用,所以这几项正常打开配置使用就行。

注意:

wifi_mod_sel必须为5,因为我是根据8723bs的参数修改的8723ds驱动,所以这里mod要选择5

rtl8723bs_lpo_use_apclk为1,我的模块的32k时钟是从cpu引出的,所以我这边设为1,如果你使用的是外部32k时钟,这里设为0
