Flash Shell Sample
##################

Overview
********
This is a simple shell module that allows arbitrary boards with flash
driver support to explore the flash device.

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

This project can be built and executed on as follows:

.. zephyr-app-commands::
   :zephyr-app: samples/drivers/flash_shell
