######################################

*Number of supported images*

Type: ``int``

Help
====

.. code-block:: none

    Sets how many application images are supported (pairs of secondary and primary slots).
    Setting this to 2 requires MCUMGR_BUF_SIZE to be at least 512b.
    NOTE: The UPDATEABLE_IMAGE_NUMBER of MCUBOOT configuration, even for Zephyr build,
    needs to be set to the same value; this is due to the fact that the mcumgr uses
    boot_util and the UPDATEABLE_IMAGE_NUMBER controls number of images supported
    by that library.
