Overview

This sample demonstrates the usage of ambiq timing scan utility.

Building and Running

The application will build only for a target that has a devicetree flash0 or psram0 alias depending on the interface used. They refers to an entry with the following bindings as a compatible:

ambiq,mspi-device

west build -b apollo5_eb samples/drivers/mspi/mspi_timing_scan
west flash
