This is the documentation for the latest (main) development branch of Zephyr. If you are looking for the documentation of previous releases, use the drop-down list at the bottom of the left panel and select the desired version.



This sample demonstrates using the flash API on a MSPI 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 flash0 alias that refers to an entry with the following bindings as a compatible:

west build -b apollo3p_evb samples/drivers/mspi/mspi_flash
west flash

Sample Output

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