		The TF-M integration sample :ref:`tfm_ipc` can be run on a STM32L562E-DK Discovery,
		using the ``stm32l562e_dk_ns`` target. When building a ``*_ns`` image with TF-M,
		a ``build/tfm/postbuild.sh`` bash script will be run automatically as a post-build step
		to make some required flash layout changes. The ``build/tfm/regression.sh`` script will
		need to be run to perform device initialization, and then run ``west flash --hex-file build/tfm_merged.hex``
		to flash the board.

		Check the ``build/tfm`` directory to ensure that the commands required by these scripts
		(``readlink``, etc.) are available on your system. Please also check ``STM32_Programmer_CLI``
		used for initialization is available in the PATH.
