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!
