ESP-IDF || CORE dump

I was writing a simple program for the led blink, the program was working fine with GPIO_NUM_2 but when the led pin num is changed to GPIO_NUM_2 the program started behave oddly, and I don't know why that is happening. Please explain what mistake I am making.

#include "freertos/FreeRTOS.h"
#include "freertos/task.h"
#include "driver/gpio.h"


# define led1 GPIO_NUM_7


void task1(void* pvParametes){
    gpio_reset_pin(led1);
    gpio_set_direction(led1, GPIO_MODE_OUTPUT);
    while (true)    
    {
        gpio_set_level(led1, 1);
        vTaskDelay(pdMS_TO_TICKS(1000));
        gpio_set_level(led1, 0);
        vTaskDelay(pdMS_TO_TICKS(1000));
    }
}

void app_main(void)
{
    xTaskCreate(task1, "LedBlink", 4096, NULL, 1, NULL);
}

GPIOs 6 to 11 are usually connected to the SPI flash memory. If you try to use them for something else, the MCU can no longer read the program it is executing and will fail.
