ap6212移植
1.ap6212
功能：wifi station、softap、wifi direct、bt、
接口类型：sdio、uart
调试方案：octopus-f1，下面以A83T平台android4.4为例说明ap6212的移植过程
2、软硬件设计部份差异说明
(1) ap6212采用的是26M晶振，A框去掉，即不需要反相器；
(2) ap6212硬件上第29脚悬空，与ap6210不同；
(3)ap6212必须采用bcmhd新驱动1.201.34.x版本，如附件；
(4)ap6212 firmware部分如附件请覆盖至\hardware\broadcom\wlan\bcmdhd\firmware。
3内核配置
3.1 .config
.config中需要配置如下选项，将wifi driver编译进内核
CONFIG_BCMDHD = y
CONFIG_BCMDHD_OOB = y
同时把ap6212驱动代码加到/android/hardware/broadcom/wlan/bcmdhd/firmware路径下。
3.2 BoardConfig.mk
BoardConfig.mk文件决定android要加载哪一款wifi模组、是否开启蓝牙和使用哪一款蓝牙模组，要配置成使用ap6212模组并启用wifi和蓝牙功能需要把BoardConfig.mk文件的相关代码修改成如下。
| # wifi and bt configuration # 1. Wifi Configuration #BOARD_WIFI_VENDOR := realtek BOARD_WIFI_VENDOR := broadcom # 1.1 broadcom wifi support ifeq ($(BOARD_WIFI_VENDOR), broadcom) BOARD_WPA_SUPPLICANT_DRIVER := NL80211 WPA_SUPPLICANT_VERSION := VER_0_8_X BOARD_WPA_SUPPLICANT_PRIVATE_LIB := lib_driver_cmd_bcmdhd BOARD_HOSTAPD_DRIVER := NL80211 BOARD_HOSTAPD_PRIVATE_LIB := lib_driver_cmd_bcmdhd BOARD_WLAN_DEVICE := bcmdhd WIFI_DRIVER_FW_PATH_PARAM := "/sys/module/bcmdhd/parameters/firmware_path" BOARD_USR_WIFI := ap6212 include hardware/broadcom/wlan/bcmdhd/firmware/$(BOARD_USR_WIFI)/device-bcm.mk endif # 2. Bluetooth Configuration # make sure BOARD_HAVE_BLUETOOTH is true for every bt vendor BOARD_HAVE_BLUETOOTH := true BOARD_HAVE_BLUETOOTH_BCM := true #BOARD_HAVE_BLUETOOTH_RTK := true #BLUETOOTH_HCI_USE_RTK_H5 := true BOARD_HAVE_BLUETOOTH_NAME := ap6212 BOARD_BLUETOOTH_BDROID_BUILDCFG_INCLUDE_DIR := device/softwinner/tulip-t1/bluetooth/ |
说明：
1、“#”符号起注释作用；
2、“BOARD_USR_WIFI := AP6210”宏指明wifi选用ap6212；
3、“BOARD_HAVE_BLUETOOTH := true”宏指明使用蓝牙；
4、“BOARD_HAVE_BLUETOOTH_BCM := true”宏指定蓝牙厂商为Broadcom；
5、“BOARD_HAVE_BLUETOOTH_NAME := ap6212”宏指明蓝牙模组名字；
6、“BOARD_BLUETOOTH_BDROID_BUILDCFG_INCLUDE_DIR := device/softwinner/tulip-t1/bluetooth/”宏指明配置文件bdroid_buildcfg.h路径；
注意：
1、需注释掉#BOARD_HAVE_BLUETOOTH_RTK := true
2、若不需要蓝牙功能只需要把相关宏注释掉就可以。
3、OARD_USR_WIFI的大小写根据你在3.1中命名规则来写。
3.3 init.sun8i.rc
这部分只要注意两点：
注意：
1、若init.sun50iw1p1.rc文件无修改后代码，可手动添加；
2、需注释掉realtek wifi和bluetooth相关内容。
3.3 octopus-f1
octopus-f1.mk文件会在编译时拷贝指定文件到特定目录下，使用ap6212需要确认如下修改：

注意：
1、android.hardware.wifi.xml拷贝到指定目录，以使设置界面显示wifi
2、android.hardware.wifi.direct.xml是在wifi设备中显示wifi direct选项
3、android.hardware.bluetooth.xml是在setting界面中显示蓝牙
4、“PRODUCT_PACKAGES += Bluetooth”指定去编译Bluetooth.apk
3.4config.xml
config.xml文件路径：\android5.1\device\softwinner\tulip-t1\overlay\frameworks\base\core\res\res
\values\config.xml
要打开蓝牙功能，需要在config.xml中把蓝牙的bt-pan网口打开，修改的部分代码如下。
