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:`CONFIG_FLASH_JESD216_API`.
