WIFI_BT
开发板使用的wifi_bt模组是 AW-NB197SM new(43438)
1 WIFI&BT配置
以x2600e_vast_v20_nand_5.10_factory_defconfig为例
1.1 wpa工具配置
打开IConfigTool工具，选择配置文件
若要使⽤wpa 相关应⽤⼯具，那么buildroot 的配置⽂件需要添加，X2600这个默认配置已经添加了，配置为buildroot_x2600_510_wifi_common_defconfig，如果没有添加可以手动选上即可。
bhu@bhu-PC:~/work/build$ cd ../buildroot/buildroot //进入buildroot目录
bhu@bhu-PC:~/work/buildroot/buildroot$ make menuconfig
可以看到wpa 相关应⽤⼯具已经添加，需要保存配置
bhu@bhu-PC:~/work/buildroot/buildroot$ cp .config ../../build/configs/buildroot/buildroot_x2600_510_wifi_common_defconfig
1.2 配置bt&wifi设备驱动
1.3 配置wifi mmc总线
1.4 kernel添加蓝牙通信串口uart3
kenny@kenny-computer:~/source/source_darwin_linux_x2000/build$ grep -nr "kernel" //先查看kernel的配置 configs/x2600e_vast_v20_nand_5.10_factory_defconfig
6:APP_kernel_dir=../kernel/kernel
7:APP_kernel_config=x2600_module_base_linux_sfc_nand_defconfig //kernel配置文件
配置文件位于kernel/kernel/arch/mips/configs目录下
kenny@kenny-computer:~/source/source_darwin_linux_x2000/kernel/kernel/arch/mips/configs$ grep -nr ".dts" ./x2600_module_base_linux_sfc_nand_defconfig
242:CONFIG_DT_X2600_MODULE_BASE_DTS_FILE="x2600_module_base.dts" //关于uart配置
x2600_module_base.dts位于kernel/kernel/module_drivers/dts/目录下,可以对需要用到的串口进行添加修改
通过文档 确定UART2方法 可知该配置用到的串口号为：UART2
/dts-v1/;
#include <dt-bindings/input/input.h>
#include "x2600.dtsi"
#include <dt-bindings/interrupt-controller/irq.h>
#include <generated/autoconf.h>
/ {
compatible = "ingenic,x2600";
/*chosen {
bootargs = "console=ttyS0,115200 mem=128M@0x0ip=off init=/linuxrc ubi.mtd=2 root=ubi0:rootfs ubi.mtd=3 rootfstype=ubifs rw flashtype=nand";
};*/
};
&uart0 {
status = "okay";
pinctrl-names = "default";
pinctrl-0 = <&uart0_pe>;
};
&uart1 {
status = "okay";
pinctrl-names = "default";
pinctrl-0 = <&uart1_pb>;
};
&uart2 {
status = "okay";
pinctrl-names = "default";
pinctrl-0 = <&uart2_pd>;
};
1.5 开机自启wifi,bt
wifi，bt 固件路径存放在⼯程⽬录下的wireless/bcm/firmware/wifi_bcm/43438_infineon，wireless/bcm/firmware/bt_bcm编译时会复制到⽂件系统 的/lib/firmware/wifi_bcm，/lib/firmware/bt_bcm⽬录.
如果选择开机⾃启，系统启动时会⾃动将固件加载
2 编译烧录
重新编译配置
bhu@bhu-PC:~/work/build$ make x2600e_vast_v20_nand_5.10_factory_defconfig
bhu@bhu-PC:~/work/build$ make
烧录固件, 没烧录过见烧录说明
3 WIFI功能验证
使用 WiFi 需要设置想要连接 WiFi 的名称及密码,将配置写入文件,启动 WiFi 时运行配置文件即可
# cd /usr/data/ //进入/usr/data/目录更改wifi配置文件
# cat wpa_supplicant.conf
ctrl_interface=/var/run/wpa_supplicant
update_config=1
network={
ssid="Guest" //需要连接的wifi名称，不要是中文名称
scan_ssid=1
psk="ingenic_guest" //需要连接的wifi密码
priority=1
}
配置完后重启,默认是开机自启wifi
# ifconfig //可以看到有wlan0出现

4 BT功能验证
查看bt是否启动，如果没有启动，则在/run/blue_bsa/目录下没有相关文件，需要手动启动 bt_enable_bsa.sh脚本
# ls /run/blue_bsa/
ble_local_keys bt-avk-fifo bt-daemon-socket
执⾏商家提供的测试命令,这些命令存放在⼯程的 wireless/bcm/bin/xburst2_bsa/app/⽬录下
bhu@bhu-PC:~/work/wireless/bcm/bin/xburst2_bsa/app$ ls
app_ag app_avk app_dg app_hh app_manager app_ops app_tm
app_av app_ble app_hd app_hs app_opc app_pan simple_app
通过adb将测试命令传到⽂件系统的/run/blue_bsa⽬录下，下⾯我⽤app_manager进⾏测试，扫描我的⼿机蓝⽛设备
