Francois Ramu ffa1532be2 samples: drivers flash add a test case for stm32 octospi This add a new sample application to test and validate the stm32 octospi driver on the NOR octo-flash present on stm32 disco kits There should be a special case to erase the complete flash.

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.

   *** Booting Zephyr OS build zephyr-v2.3.0-2142-gca01d2e1d748  ***

   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!
