Anas Nashif 3ae52624ff license: cleanup: add SPDX Apache-2.0 license identifier
Update the files which contain no license information with the
'Apache-2.0' SPDX license identifier.  Many source files in the tree are
missing licensing information, which makes it harder for compliance
tools to determine the correct license.

By default all files without license information are under the default
license of Zephyr, which is Apache version 2.

FAT Filesystem Sample Application
###################################

Overview
********

This sample app demonstrates use of the filesystem API and uses the FAT file
system driver to mount an SDHC card connected over SPI bus.

Requirements
************

This project requires a SDHC or microSD card formatted with FAT filesystem.
See the :ref:`SDHC_disks` documentation for Zephyr implementation details.

Building and Running
********************

This sample can be built for an ``nrf52840_blip`` board. It requires
both the ``nrf52840_blip.overlay`` and the ``dts_fixup.h`` for nrf52840_blip
to work:

.. zephyr-app-commands::
   :zephyr-app: samples/subsys/fs
   :board: nrf52840_blip
   :goals: build
   :compact:

To run this sample, a FAT formatted microSD card should be present in the
microSD slot of ``nrf52840_blip`` board. If there are any files or directories
present in the card, the sample lists them out on the debug serial output.
