No source available for <signal handler called>() at 0xfffffffe

[Kendall7]

Hi,

I am not able to run my FreeRtos in Non secure region when trust zone is enabled.

When I did the debugging it's going to the infinite loop ,getting message as "No source available for <signal handler called>() at 0xfffffffe"

The above are the configuration setting I have enabled.

I am getting the above message when I did the debugging.

  */
void MX_FREERTOS_Init(void) {

  /* creation of defaultTask */
  defaultTaskHandle = osThreadNew(StartDefaultTask, NULL, &defaultTask_attributes);
}

void StartDefaultTask(void *argument)
{
  /* USER CODE BEGIN defaultTask */
  /* Infinite loop */
  for(;;)
  {
	  HAL_GPIO_TogglePin(LED_GPIO_Port,LED_Pin);
	  osDelay(1);
  }
  /* USER CODE END defaultTask */
}

I am doing simple LED_toggle in FreeRtos task in Non secure region.
