JESD216 Sample
##############

Overview
********

This sample demonstrates how to use the JESD216 flash API to extract
information from a compatible serial device, and serves as utility to
generate ``jedec,spi-nor`` devicetree property values for the device.

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

The application will build only for a target that has a devicetree entry
with ``jedec,spi-nor`` as a compatible, and for which the driver
supports :kconfig:option:`CONFIG_FLASH_JESD216_API`.
