.. zephyr:code-sample:: spi-nor
   :name: JEDEC SPI-NOR flash
   :relevant-api: flash_interface

   Use the flash API to interact with an SPI NOR serial flash memory device.

Overview
********

This sample demonstrates using the :ref:`flash API <flash_api>` on a SPI NOR serial flash
memory device.  While trivial it is an example of direct access and
allows confirmation that the flash is working and that automatic power
savings is correctly implemented.

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

The application will build only for a target that has a devicetree node with one of the
following bindings as a compatible:

* :dtcompatible:`jedec,spi-nor`,
* :dtcompatible:`st,stm32-qspi-nor`,
* :dtcompatible:`st,stm32-ospi-nor`,
* :dtcompatible:`nordic,qspi-nor`.

   JEDEC QSPI-NOR SPI flash testing
   ==========================

   Test 1: Flash erase
   Flash erase succeeded!

   Test 2: Flash write
   Attempting to write 4 bytes
   Data read matches data written. Good!
