History

Aksel Skauge Mellbye bc6c363bc9 boards: silabs: Consistently name dev kits Rename all Silicon Labs dev kits to always use the official kit name as board target name. Previous kit names used various naming schemes, including putting part of the SoC name in the board name. With HWMv2, SoC names (if needed) should go in the SoC board qualifier. Use HWMv2 revisions for the two variants of SLTB010A. Split the xG27 Dev Kit from the EFR32BG22 Thunderboard. This attempt at deduplication is confusing due to the very different kit names and use of different ICs (BG22 vs BG27), and was not continued with the xG24 Dev Kit, meaning that it wasn't consistent.

.. zephyr:code-sample:: jesd216
   :name: JESD216 flash
   :relevant-api: flash_interface

   Use the JESD216 flash API to extract information from a compatible serial memory device.

Overview
********

This sample demonstrates how to use the JESD216 flash API to extract
information from a compatible serial device, and serves as utility to
generate ``jedec,spi-nor`` devicetree property values for the device.

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

The application will build only for a target that has a devicetree entry
with ``jedec,spi-nor`` as a compatible, and for which the driver
supports :kconfig:option:`CONFIG_FLASH_JESD216_API`.
