.. 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`.

한국어 전문 번역

개요

이 sample은 SPI NOR serial flash memory device에서 flash API를 사용하는 방법을 보여줍니다. 간단한 예제지만 flash에 직접 접근하여 정상 동작과 automatic power saving 구현을 확인할 수 있습니다.

Build와 실행

Application은 devicetree node에 다음 binding 중 하나가 compatible로 지정된 target에서만 build됩니다.

  • jedec,spi-nor
  • st,stm32-qspi-nor
  • st,stm32-ospi-nor
  • nordic,qspi-nor
west build -b nrf52840dk/nrf52840 samples/drivers/spi_flash
west flash

Sample 출력

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