Core dump:Guru Meditation Error: Core 0 panic'ed (Unhandled debug exception)

Postby azz-zza » Sat Oct 12, 2019 2:32 pm

Hello,
im at my wits end and would appreciate your guidance, please.
the following basic code falls with the core dump.

Code: Select all

#include <stdio.h>
#include <string.h>
#include "freertos/FreeRTOS.h"
#include <unistd.h>
#include "esp_timer.h"
#include "esp_log.h"
#include "esp_sleep.h"
#include "sdkconfig.h"
#include "freertos/event_groups.h"
#include "driver/gpio.h"

#define BLUE_PIN GPIO_NUM_2

void CallBack(TimerHandle_t handle);

extern "C" void app_main(void) {
    xTimerHandle timerHndl1Sec;
    BaseType_t timerstarted;

    timerHndl1Sec = xTimerCreate(
                        "timer1Sec", /* name */
                        pdMS_TO_TICKS(1000), /* period/time */
                        pdTRUE, /* auto reload */
                        (void*)0, /* timer ID */
                        CallBack /* callback */
                    );

    gpio_pad_select_gpio(BLUE_PIN);
    gpio_set_direction(BLUE_PIN,GPIO_MODE_OUTPUT);
    gpio_set_level(BLUE_PIN,1);

    if (timerHndl1Sec !=NULL) {
        printf("Starting Timer");
        timerstarted = xTimerStart( timerHndl1Sec, 0 );
        if (timerstarted == pdPASS) {
            vTaskStartScheduler();
        };
    };

    if (timerHndl1Sec==NULL) {
        for(;;); /* failure! */
    };

};

void CallBack(TimerHandle_t handle) {
    printf("turning on and off");
//    gpio_set_level(BLUE_PIN, 1); /* toggle red LED */
//    usleep(2000);
//    gpio_set_level(BLUE_PIN, 0); /* toggle red LED */
};


And the output is

Code: Select all

after adding logging and err checking the error went away and the code started to work //faceplam
