JEDEC MSPI-NOR flash
Overview
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:
ambiq,mspi-device, mspi-atxp032
west build -b apollo3p_evb samples/drivers/mspi/mspi_flash
west flash
Sample Output
*** Booting Zephyr OS build zephyr-v2.3.0-2142-gca01d2e1d748 ***
