|
|
|
|
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`.
