平台:全志A33Android4.4
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:/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A33Android4.4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/Kconfigindex 33409594d0..0055f4567c 100755--- a/lichee/linux-3.4/drivers/net/wireless/Kconfig+++ b/lichee/linux-3.4/drivers/net/wireless/Kconfig@@ -297,4 +297,5 @@ source "drivers/net/wireless/rtl8189es/Kconfig"source "drivers/net/wireless/rtl8723bs/Kconfig"source "drivers/net/wireless/rtl8723bu/Kconfigsource "drivers/net/wireless/esp8089/Kconfig"+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/Makefileindex 186b119d30..d24cd3cf45 100755--- a/lichee/linux-3.4/drivers/net/wireless/Makefile+++ b/lichee/linux-3.4/drivers/net/wireless/Makefile@@ -30,6 +30,7 @@ obj-$(CONFIG_RTL8189ES) += rtl8189es/obj-$(CONFIG_RTL8723BS) += rtl8723bs/obj-$(CONFIG_RTL8723BS)+= rtl8723bu/obj-$(CONFIG_ESP8089) += esp8089/+obj-$(CONFIG_RTL8723DS)+= rtl8723ds/# 16-bit wireless PCMCIA client driversobj-$(CONFIG_PCMCIA_RAYCS)+= ray_cs.o
(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.mkindex a2669cdbef..c1d191bae7 100755--- a/android4.4/device/softwinner/astar-y3/BoardConfig.mk+++ b/android4.4/device/softwinner/astar-y3/BoardConfig.mk@@ -27,8 +27,8 @@ ifeq ($(BOARD_WIFI_VENDOR), realtek)BOARD_HOSTAPD_DRIVER := NL80211BOARD_HOSTAPD_PRIVATE_LIB := lib_driver_cmd_rtl-SW_BOARD_USR_WIFI := rtl8723bu-BOARD_WLAN_DEVICE := rtl8723bu+ SW_BOARD_USR_WIFI := rtl8723ds+ BOARD_WLAN_DEVICE := rtl8723ds#SW_BOARD_USR_WIFI := rtl8188eu#BOARD_WLAN_DEVICE := rtl8188eu@@ -86,7 +86,7 @@ BOARD_HAVE_BLUETOOTH := true#SW_BOARD_HAVE_BLUETOOTH_NAME := ap6330BOARD_HAVE_BLUETOOTH_RTK := true#BLUETOOTH_HCI_USE_RTK_H5 := true-SW_BOARD_HAVE_BLUETOOTH_NAME := rtl8723bs+SW_BOARD_HAVE_BLUETOOTH_NAME := rtl8723ds# boostup code will on command to set CPU roomage and DDR freq# default enable
2.修改 hardware/libhardware_legacy/wifi/Android.mk
diff --git a/android4.4/hardware/libhardware_legacy/wifi/Android.mk b/android4.4/hardware/libhardware_legacy/wifi/Android.mkindex bd89033896..f99f28038d 100755--- a/android4.4/hardware/libhardware_legacy/wifi/Android.mk+++ b/android4.4/hardware/libhardware_legacy/wifi/Android.mk@@ -55,6 +55,12 @@ LOCAL_CFLAGS += -DRTL_8723BU_WIFI_USEDLOCAL_CFLAGS += -DRTL_WIFI_VENDORendif+#realtek sdio wifi+bt module+ifeq ($(SW_BOARD_USR_WIFI), rtl8723ds)+LOCAL_CFLAGS += -DRTL_8723DS_WIFI_USED+LOCAL_CFLAGS += -DRTL_WIFI_VENDOR+endif+#espressif sdio wifi moduleifeq ($(SW_BOARD_USR_WIFI), esp8089)LOCAL_CFLAGS += -DESPRESSIF_ESP8089_WIFI_USED
3.修改hardware/libhardware_legacy/wifi/wifi.c
diff --git a/android4.4/hardware/libhardware_legacy/wifi/wifi.c b/android4.4/hardware/libhardware_legacy/wifi/wifi.cindex ce32ea4b43..fac4e489c6 100755--- a/android4.4/hardware/libhardware_legacy/wifi/wifi.c+++ b/android4.4/hardware/libhardware_legacy/wifi/wifi.c@@ -116,6 +116,18 @@ static char primary_iface[PROPERTY_VALUE_MAX];#define WIFI_DRIVER_MODULE_ARG"ifname=wlan0 if2name=p2p0"#endif+#elif defined RTL_8723DS_WIFI_USED+ /* rtl8723DS sdio+bt wifi */+ #ifndef WIFI_DRIVER_MODULE_PATH+ #define WIFI_DRIVER_MODULE_PATH "/system/vendor/modules/8723ds.ko"+ #endif+ #ifndef WIFI_DRIVER_MODULE_NAME+ #define WIFI_DRIVER_MODULE_NAME "8723ds"+ #endif+ #ifndef WIFI_DRIVER_MODULE_ARG+ #define WIFI_DRIVER_MODULE_ARG"ifname=wlan0 if2name=p2p0"+ #endif+#elif defined ESPRESSIF_ESP8089_WIFI_USED/* esp8089 sdio wifi */#ifndef WIFI_DRIVER_MODULE_PATH
将编译后的ko文件添加到android4.4/device/softwinner/astar-y3/modules/modules/目录下。
上面添加完之后,系统开机后就能自动加载8723.ko驱动,具体的加载流程我就不描述了。这里简单说下加载ko文件是在hardware/libhardware_legacy/wifi/wifi.c下的int wifi_load_driver() 加载对应的wifi驱动
三、添加fw和config固件
1.修改astar_y3.mk
--- a/android4.4/device/softwinner/astar-y3/astar_y3.mk+++ b/android4.4/device/softwinner/astar-y3/astar_y3.mk@@ -71,6 +71,9 @@ PRODUCT_COPY_FILES += \#$(call inherit-product-if-exists, hardware/broadcom/wlan/firmware/ap6210/device-bcm.mk)#$(call inherit-product-if-exists, hardware/broadcom/wlan/firmware/ap6330/device-bcm.mk)+#rtl8723ds bt fw and config+$(call inherit-product, hardware/realtek/bluetooth/rtl8723ds/firmware/rtlbtfw_cfg.mk)+#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:/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.rcindex 7a9d9f63f1..df52fac6e0 100755--- a/android4.4/device/softwinner/astar-y3/init.sun8i.rc+++ b/android4.4/device/softwinner/astar-y3/init.sun8i.rc# UART device-# chmod 0666 /dev/rtk_btusb-# chown bluetooth net_bt_stack /dev/rtk_btusb+chmod 0666 /dev/ttyS1+chown bluetooth net_bt_stack /dev/ttyS1## power up/down interfacechmod 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
diff --git a/lichee/tools/pack/chips/sun8iw5p1/configs/y3/sys_config.fex b/lichee/tools/pack/chips/sun8iw5p1/configs/y3/sys_config.fexindex 47e2de7f28..21ff98692d 100755--- a/lichee/tools/pack/chips/sun8iw5p1/configs/y3/sys_config.fex+++ b/lichee/tools/pack/chips/sun8iw5p1/configs/y3/sys_config.fex@@ -259,11 +259,12 @@ uart_rx = port:PF04<3><1><default><default>[uart1]uart_used = 1-uart_type = 2+uart_port= 1+uart_type = 4uart_tx = port:PG06<2><1><default><default>uart_rx = port:PG07<2><1><default><default>-;uart_rts = port:PG08<2><1><default><default>-;uart_cts = port:PG09<2><1><default><default>+uart_rts = port:PG08<2><1><default><default>+uart_cts = port:PG09<2><1><default><default>[uart2]uart_used = 1@@ -786,19 +787,18 @@ sdc_regulator= "none"[mmc1_para]sdc_used= 1-sdc_detmode = 2+sdc_detmode = 4sdc_buswidth= 4-sdc_clk = port:PG00<2><1><1><default>-sdc_cmd = port:PG01<2><1><1><default>-sdc_d0 = port:PG02<2><1><1><default>-sdc_d1 = port:PG03<2><1><1><default>-sdc_d2 = port:PG04<2><1><1><default>-sdc_d3 = port:PG05<2><1><1><default>-sdc_det = port:PB04<4><1><2><default>-sdc_power_supply = "axp22_dcdc1"+sdc_clk = port:PG00<2><1><2><default>+sdc_cmd = port:PG01<2><1><2><default>+sdc_d0 = port:PG02<2><1><2><default>+sdc_d1 = port:PG03<2><1><2><default>+sdc_d2 = port:PG04<2><1><2><default>+sdc_d3 = port:PG05<2><1><2><default>+sdc_det = sdc_use_wp = 0sdc_wp =-sdc_isio= 0+sdc_isio= 1sdc_regulator= "none"[mmc2_para]@@ -938,13 +938,13 @@ lsm303d = 1;--------------------------------------------------------------------------------[wifi_para]wifi_used= 1-wifi_sdc_id = 0+wifi_sdc_id = 1wifi_usbc_id = 1wifi_usbc_type= 1-wifi_mod_sel = 3-wifi_power = ""-wifi_power_ext1 = ""-wifi_power_ext2 = ""+wifi_mod_sel = 5+wifi_power = +wifi_power_ext1 = +wifi_power_ext2 = wifi_power_switch = ;port:PH09<1><0><default><0>; 1 - ap6181 sdio wifi gpio config@@ -965,13 +965,13 @@ wifi_power_switch = ;port:PH09<1><0><default><0>; 4 - rtl8723au usb wifi + bt; 5 - rtl8723bs sdio wifi + bt-;rtl8723bs_chip_en = port:PL11<1><default><default><0>-;rtl8723bs_wl_regon= port:PL06<1><default><default><0>-;rtl8723bs_wl_host_wake = port:PL07<4><default><default><0>-;rtl8723bs_bt_regon= port:PL08<1><default><default><0>-;rtl8723bs_bt_wake = port:PL10<1><default><default><0>-;rtl8723bs_bt_host_wake = port:PL09<4><default><default><0>-;rtl8723bs_lpo_use_apclk = 0+rtl8723bs_chip_en = +rtl8723bs_wl_regon= port:PL02<1><default><default><0>+rtl8723bs_wl_host_wake = port:PL07<4><default><default><0>+rtl8723bs_bt_regon= port:PL08<1><default><default><0>+rtl8723bs_bt_wake = port:PL10<1><default><default><0>+rtl8723bs_bt_host_wake = port:PL09<4><default><default><0>+rtl8723bs_lpo_use_apclk = 1; 6 - eagle sdio wifi;esp_wl_chip_en = port:PL03<1><default><default><0>@@ -984,7 +984,7 @@ wifi_power_switch = ;port:PH09<1><0><default><0>;--------------------------------------------------------------------------------[bt_para]bt_used = 1-bt_uart_id= ;1+bt_uart_id= 1;--------------------------------------------------------------------------------;3G configuration
以上修改完成后,驱动就能正常使用了
