Hi,

i am trying to initialize wifi in my project, i had done this earlier i had written small piece of code earlier that was working fine, but i have tried copying same code in new project and it doesnt work, the snippet of code is as below,

Code: Select all

app_main(){
//Initialize NVS
    esp_err_t ret = nvs_flash_init();
    if (ret == ESP_ERR_NVS_NO_FREE_PAGES || ret == ESP_ERR_NVS_NEW_VERSION_FOUND) {
      ESP_ERROR_CHECK(nvs_flash_erase());
      ret = nvs_flash_init();
    }
    ESP_ERROR_CHECK(ret);
    /** init GPIO first for default pin */	
    init_gpio();
    
     #if 1
    // Initialize TCP/IP network interface (should be called only once in application)
    ESP_ERROR_CHECK(esp_netif_init());
    #endif
    // Create default event loop that running in background
    ESP_ERROR_CHECK(esp_event_loop_create_default());
    
    #if 0
    tcpip_adapter_init();

    ESP_ERROR_CHECK(esp_event_loop_create_default());
#endif

	/*V42 onboard esp netif uses instead of tcpip_adapter*/
	esp_netif_t *local_sta_netif = esp_netif_create_default_wifi_sta();

	#if __WIFI_MANAGER_LVL0__
	ESP_LOGI(TAG, "NETIF from sta = 0x%X", (uint32_t) local_sta_netif );
	#endif
	
    wifi_init_config_t cfg = WIFI_INIT_CONFIG_DEFAULT();
    ESP_ERROR_CHECK(esp_wifi_init(&cfg));
	/*loop forever to detect error*/
	for(;;) 
	{}
}

error log generated is as below
