Prefetch buffer.

I am trying to enable the prefetch buffer, but this causes the MCU to crash. See below for code snippet.

/* STM32F405x/407x/415x/417x Revision Z devices: prefetch is supported  */
  if (HAL_GetREVID() == 0x1001)
  {
    /* Enable the Flash prefetch */
    __HAL_FLASH_PREFETCH_BUFFER_ENABLE();
  }

Can some one tell me if this is supported in the mbed lib, or why it does not work.
