+JEDEC SPI-NOR Sample
+####################
+
+Overview
+********
+
+This sample demonstrates using the 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 :ref:`devicetree
+<dt-guide>` entry with ``jedec,spi-nor`` as a compatible.

+   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!
