C++ error: Guru Meditation Error: Core 0 panic'ed (InstructionFetchError). Exception was unhandled
Posted: Mon Mar 20, 2023 5:03 pm
I'm buiding a simple task project with C++, with the following code:
My root CMakeLists.txt:
# For more information about build system see
# https://docs.espressif.com/projects/esp ... ystem.html
# The following five lines of boilerplate have to be in your project's
# CMakeLists in this exact order for cmake to work correctly
cmake_minimum_required(VERSION 3.16)
set(CMAKE_CXX_STANDARD 17)
set(EXTRA_COMPONENT_DIRS components)
include($ENV{IDF_PATH}/tools/cmake/project.cmake)
project(test)
When running on the device I'm getting the following error in a loop:
I can't find out what is wrong or if this is something related to C++.
Help appreciated to make my code run without errors.
Code: Select all
#include <stdio.h>
#include "esp_log.h"
#include <freertos/FreeRTOS.h>
#include <freertos/task.h>
static const char *TAG = "main";
void task(void *params)
{
while (true)
{
ESP_LOGD(TAG, "Tick...");
vTaskDelay(1000);
}
}
extern "C" void app_main(void)
{
ESP_LOGI(TAG, "Starting the scheduler...");
xTaskCreate(&task, "Test Task", 10000, NULL, 1, NULL);
vTaskStartScheduler();
while (true)
{
ESP_LOGE(TAG, "Problem with heap memory...");
}
}
