Keep getting RTCWDT_SYS_RESET

[richard.kang]

I am trying to write a blinky on ESP32 ESP-WROVER-KIT v4 as below, but keep getting RTCWDT_SYS_RESET as error stacks after the codes

What is the best way to debug this? I couldn't get the Watchdog to trigger the debug on the wrover-kit

11. void LEDBlinkTask (void *pvParameters)
12. {
13. //  configPRINTF( ( "Setting GPIO direction...\r\n" ) );
14.     gpio_set_direction(GPIO_NUM_2,GPIO_MODE_OUTPUT);
15.     while(1)
16.     {
17.         vTaskDelay( pdMS_TO_TICKS( 10000 ) );
18.         gpio_set_level(GPIO_NUM_2, 1);
19.  
20.         vTaskDelay( pdMS_TO_TICKS( 10000 ) );
21.         gpio_set_level(GPIO_NUM_2, 0);
22.     }
23. }
24.  
25. void vStartLEDblinkTask( void )
26. {
27.     BaseType_t xReturned;
28.     configPRINTF( ( "Blink...\r\n" ) );
29.  
30.     xReturned = xTaskCreate(LEDBlinkTask, "Blink", 256, NULL, tskIDLE_PRIORITY, NULL);
31.     if( xReturned == pdPASS )
32.     {
33.         configPRINTF( ( "Blink task created...\r\n" ) );
34.     }
35. }
