RTL8723BU-WiFi-BT模块移植WiFi部分

1、. 本次修改基于厂商提供的包下载：一修改记录：1.配置linu*核 (1)Networking support -Wireless下增加802.11 协议栈的支持- Wireless cfg80211 - wireless configuration API* nl80211 testmode mand * enable developer warnings * cfg80211 regulatory debugging* enable powersave by default cfg80211 DebugFS entries use statically piled regulatory r

2、ules database * cfg80211 wireless e*tensions patibility * Wireless e*tensions sysfs files-*- mon routines for IEEE802.11 drivers lib80211 debugging messages * Allow reconnect while already connected Generic IEEE 802.11 Networking Stack (mac80211) PID controller based rate control algorithm * Minstre

3、l* Minstrel 802.11n support Default rate control algorithm (Minstrel) - * Enable mac80211 mesh networking (pre-802.11s) support * Enable LED triggers E*port mac80211 internals in DebugFS Select mac80211 debugging features -(2) 配置Device Drivers -USB support - USB Wireless Device Management support 支持

4、WIFI2.将下的压缩包拷贝到ANDROID_SDK/kernel_im*/drivers/net/wireless下，解压，修改其Makefile，编译wifi驱动模块,修改容如下：CONFIG_PLATFORM_IM*6Q = yifeq ($(CONFIG_PLATFORM_IM*6Q), y)E*TRA_CFLAGS += -DCONFIG_LITTLE_ENDIANE*TRA_CFLAGS += -DCONFIG_IOCTL_CFG80211 -DRTW_USE_CFG80211_STA_EVENT -DCONFIG_PLATFORM_ANDROID -DCONFIG_ANDROID

7、iphy_registerrtl8723bu: Unknown symbol wiphy_register (err -22)原因就是：编译WiFi模块时会去KSRC所指的路径下找相应的库，假设果相关的编译选项没有选上会导致*些库缺失，从而导致编出来的WiFi模块不完整。上述是由于编译核时有勾选80211协议栈导致。3.用厂商提供的hardware/realtek 替换hardware/realtek4.用厂商提供的替换ANDROID_SDK/e*tern/wpa_supplicant_8，并修改文件夹的名字为wpa_supplicant_8。5.hardware/libhardware_le

17、te*ts上述步骤完成后，到根目录下执行make 编译整个系统。二测试1.安装cfg80211.ko，8723bu.ko依赖此模块，缺省会报如下错误：8723bu: Unknown symbol cfg80211_ready_on_channel (err 0)8723bu: Unknown symbol _ieee80211_get_channel (err 0)8723bu: Unknown symbol cfg80211_roamed (err 0)8723bu: Unknown symbol wiphy_register (err 0)8723bu: Unknown symbol cf

20、bin/wpa_supplicant -Dnl80211 -iwlan0 -c/etc/wifi/wpa_supplicant.conf，启动wpa_supplicant进程。启动过程报如下错误：E/wpa_supplicant( 3251): mkdirctrl_interface=wlan0: Permission deniedE/wpa_supplicant( 3251): Failed to initialize control interface wlan0.E/wpa_supplicant( 3251): You may have another wpa_supplicant pr

22、，没有匹配成功，导致进程启动失败。原来ctrl_interface的路径是/var/run/wpa_supplicant，把ctrl_interface改成/data/misc/wifi/wpa_supplicant就可以了。ctrl_interface在哪里？在工程下的e*ternal/wpa_supplicant_8/wpa_supplicant/wpa_supplicant.conf中。深入分析：wpa_supplicant_init_iface函数分析init_iface初始化的第一个工作是解析运行时配置文件。其中，wpa_s-confname的值为/data/misc/wifi/wp

23、a_supplicant.conf,解析函数是wpa_config_read。wpa_s-ctrl_iface = wpa_supplicant_ctrl_iface_init(wpa_s); if (wpa_s-ctrl_iface = NULL) wpa_printf(MSG_ERROR, Failed to initialize control interface %s.n You may have another wpa_supplicant process already running or the file wasn left by an unclean termination

24、of wpa_supplicant in which case you will needn to manually remove this file before starting wpa_supplicant again.n, wpa_s-conf-ctrl_interface); return -1; 如果是linu*系统，可能没有wpa_supplicant工具，可参考wpa_supplicant-2.6穿插编译，移植此工具。5.执行system/bin/wpa_cli -p/data/misc/wifi/wpa_supplicant，配置并连接wifi热点。Could not con
