Keep getting RTCWDT_SYS_RESET

Postby richard.kang » Thu Nov 15, 2018 3:20 pm

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
  1. /* Standard includes. */
  2. #include <stdio.h>
  3. #include <string.h>
  4.  
  5. /* FreeRTOS includes. */
  6. #include "FreeRTOS.h"
  7. #include "task.h"
  8.  
  9. #include "driver/gpio.h"
  10.  
  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. }

Where's your main() function and what does it do?
