Additional context
Before:

static void my_flash_callback(void *event)
{
	uint32_t event_code = FLASH_ERR_FAILURE;
	event_code = *((uint32_t*)event);
    if((event_code == FLASH_INT_EVENT_WRITE_COMPLETE) || (event_code == FLASH_INT_EVENT_ERASE_COMPLETE))
    {
    	flash_error_code = FLASH_SUCCESS;
    }

After

static void my_flash_callback(void *event)
{
	uint32_t event_code = FLASH_ERR_FAILURE;
	event_code = *((uint32_t*)event);
        flash_error_code = 0xffffffff; /* error */
    if((event_code == FLASH_INT_EVENT_WRITE_COMPLETE) || (event_code == FLASH_INT_EVENT_ERASE_COMPLETE))
    {
    	flash_error_code = FLASH_SUCCESS;
    }

Thank you!
