Erasing flash during RTOS task execution on STM32F4

[SGasp.1]

Hi ..

I am using this function to erase some sectors on the flash

bool FLASH_EraseSectors(uint32_t starting_sector , uint8_t number_of_sectors)
{
	FLASH_EraseInitTypeDef erase_init;
	uint32_t page_error;
 
    /* Erase the user Flash area */
	erase_init.Banks        = FLASH_BANK_1;
	erase_init.TypeErase   	= FLASH_TYPEERASE_SECTORS;
	erase_init.NbSectors 	= number_of_sectors;
	erase_init.Sector     	= starting_sector;
	erase_init.VoltageRange = FLASH_VOLTAGE_RANGE_3;
 
	/* Unlock the Flash to enable the flash control register access *************/
	FLASH_Unlock();
 
	if (HAL_FLASHEx_Erase(&erase_init, &page_error) != HAL_OK)
	{
		FLASH_Lock();
		return false;
	}
	if (HAL_FLASHEx_Erase(&erase_init, &page_error) == HAL_OK)
	{
		FLASH_Lock();
		return true;
	}
 
}

I would like to erase some sectors without breaking the 2 tasks running...

The point is that it seems to destroy the tasks...

Is there a safe way to delete the sectors in flash during a task execution in FREERTOS ?

Thanks a lot

If it's blocking then how can this FLASH_WaitForLastOperation run after FLASH_Program_Word?

By stalling do you mean it stops until erase is done? Not permanently stalling I guess.
