.. warning:: Ram and Flash values reported by "free" are totally seperate from values the Mecrisp-Stellaris Kernel uses. These values are preset and used when the Kernel is compiled. To configure the Kernel memory values for your MCU see :ref:`Changing Kernel Flash and Ram values<change-kernel-flash-ram>`. Using these preset Kernel memory values, Mecrisp-Stellaris will print warnings when Flash or Ram reserves are exhausted.
