本文主要是介绍android-AP6212配置，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！
一、调试背景
硬件平台a33
系统android
wifi:ap6212a
从内核日志看到模块能加载识别到fw_bcm43438a1.bin ,但是nvram加载的配置是nvram_ap6212.txt，虽然能正常工作，但是对比了一下nvram_ap6212.txt 和nvram_ap6212a.txt还是有差异的

};3.3hal 解析底层探测到的wifi设备信息，将解析的模块信息写入
property_set(“wlan.hardware.info”, info);

}3.4 最后查看到wifi_list 只定义device_id = 0x1a9a6 ，解析出来的模块是ap6212
void get_driver_module_arg(char* arg) 设置nvram_path的时候只识别出ap6212
android/hardware/libhardware_legacy/wifi_hardware_info/wifi_hardware_info.c
struct wifi_hardware_info {unsigned long device_id;char *module_name;char *driver_name;char *driver_module_name;char *vendor_name;char *fw_path_sta;char *fw_path_ap;char *fw_path_p2p;
};static const struct wifi_hardware_info wifi_list[] = {{.device_id = 0x1a9a6, //设备ID，通过内核sdio_probe 可以查看到此ID .module_name = "ap6212", //模块名字.driver_name = "bcmdhd", //驱动名字.driver_module_name = "bcmdhd",.vendor_name = "broadcom",.fw_path_sta = "/system/vendor/modules/fw_bcm43438a0.bin", //驱动bin文件.fw_path_ap = "/system/vendor/modules/fw_bcm43438a0_apsta.bin",.fw_path_p2p = "/system/vendor/modules/fw_bcm43438a0_p2p.bin",}
}void get_driver_module_arg(char* arg)
{char module_arg[256] = {0};#if defined(WIFI_VENDOR_NAME) && defined(WIFI_MODULE_NAME) && defined(WIFI_DRIVER_NAME) && defined(WIFI_DRIVER_MODULE_NAME)#ifdef WIFI_DRIVER_MODULE_ARGconst char *driver_module_arg = WIFI_DRIVER_MODULE_ARG;snprintf(module_arg, sizeof(module_arg), "%s", driver_module_arg);
#endif#elseconst char *vendor_name = get_wifi_vendor_name();if(strcmp(vendor_name, "realtek") == 0) {const char *driver_module_arg = "ifname=wlan0 if2name=p2p0";snprintf(module_arg, sizeof(module_arg), "%s", driver_module_arg);} else if(strcmp(vendor_name, "broadcom") == 0) {const char *nvram_path = "nvram_path=/system/vendor/modules/nvram";const char *config_path = "config_path=/system/vendor/modules/config";snprintf(module_arg, sizeof(module_arg), "%s_%s.txt %s_%s.txt",nvram_path, get_wifi_module_name(), config_path, get_wifi_module_name());}else if(strcmp(get_wifi_vendor_name(), "xradio") == 0) {const char *driver_module_arg = "";snprintf(module_arg, sizeof(module_arg), "%s", driver_module_arg);} else if(strcmp(vendor_name, "atheros") == 0){const char *driver_module_arg = "";snprintf(module_arg, sizeof(module_arg), "%s", driver_module_arg);}
#endifstrcpy(arg, module_arg);
}
解决如下：
android/hardware/libhardware_legacy/wifi_hardware_info/wifi_hardware_info.cstatic const struct wifi_hardware_info wifi_list[] = {{.device_id = 0x0a9a6, //设备ID，通过内核sdio_probe 可以查看到此ID .module_name = "ap6212", //模块名字.driver_name = "bcmdhd", //驱动名字.driver_module_name = "bcmdhd",.vendor_name = "broadcom",.fw_path_sta = "/system/vendor/modules/fw_bcm43438a0.bin", //驱动bin文件.fw_path_ap = "/system/vendor/modules/fw_bcm43438a0_apsta.bin",.fw_path_p2p = "/system/vendor/modules/fw_bcm43438a0_p2p.bin",}， {.device_id = 0x1a9a6, //设备ID，通过内核sdio_probe 可以查看到此ID .module_name = "ap6212a", //模块名字.driver_name = "bcmdhd", //驱动名字.driver_module_name = "bcmdhd",.vendor_name = "broadcom",.fw_path_sta = "/system/vendor/modules/fw_bcm43438a1.bin", //驱动bin文件.fw_path_ap = "/system/vendor/modules/fw_bcm43438a1_apsta.bin",.fw_path_p2p = "/system/vendor/modules/fw_bcm43438a1_p2p.bin",}
}
这样就能正确加载nvram_ap6212a.txt
