平臺:全志A33?Android4.4

模塊：RTL8723DS

接口：SDIO、uart1（ttyS1）

kernel：Linux3.4

?

一、?移植8723ds驅動，讓驅動參與編譯

? ? 1.將rtl8723ds驅動源碼放到linux-3.4/drivers/net/wireless/目錄下，并生成一個rtl8723ds目錄

驅動下載地址:https://download.csdn.net/download/Mrdeath/13744931

注意：該驅動不是原版驅動，而是經過了我的修改去適配了A33?Android4.4的SDK，由于A33源碼里面并沒有8723ds的源碼，所以sys_config.fex,以及rf目錄下沒有針對8723ds的電源控制，所以如果你是完全參考我方案來移植，請務必使用該版驅動。

? ? 2.修改配置文件添讓驅動參與編譯：

? ? ? (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 --- 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/Makefile index 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里勾選rtl8723ds驅動，作為模塊編譯

?

配置完上面內容后，rtl8723ds驅動就能正確參與編譯了。

?

二、?配置系統開機自動加載8723ds驅動

? ? 1.修改BoardConfig.mk

SW_BOARD_USR_WIFI、BOARD_WLAN_DEVICE、SW_BOARD_HAVE_BLUETOOTH_NAME值改為8723ds

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

? ?將編譯后的ko文件添加到android4.4/device/softwinner/astar-y3/modules/modules/目錄下。? ??

? ?上面添加完之后，系統開機后就能自動加載8723.ko驅動，具體的加載流程我就不描述了。這里簡單說下加載ko文件是在hardware/libhardware_legacy/wifi/wifi.c下的int wifi_load_driver() 加載對應的wifi驅動

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.將hw_bt_rtl8723ds.tar.gz壓縮包解壓到hardware/realtek/bluetooth目錄下

目錄名字重命名為rtl8723ds

?包下載地址:https://download.csdn.net/download/Mrdeath/13745180

注意：如果你的bt使用的接口不是ttyS1，請修改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參數

1.修改init.sun8i.rc

藍牙串口改為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 --- 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]那一欄，我設置的是8723bs的參數，其實這里我是對8723ds的電源管理參考8723bs進行了修改，所以這些參數同樣針對8723ds能使用，所以這幾項正常打開配置使用就行。

注意：

wifi_mod_sel必須為5，因為我是根據8723bs的參數修改的8723ds驅動，所以這里mod要選擇5

rtl8723bs_lpo_use_apclk為1，我的模塊的32k時鐘是從cpu引出的，所以我這邊設為1，如果你使用的是外部32k時鐘，這里設為0

diff --git a/lichee/tools/pack/chips/sun8iw5p1/configs/y3/sys_config.fex b/lichee/tools/pack/chips/sun8iw5p1/configs/y3/sys_config.fex index 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，驅動就能正常使用了
