Overview

This sample demonstrates using the MSPI API on a MSPI memory device. The asynchronous transceive call need to be supported either by a software queue or hardware queue from the controller hardware. To this sample, however, the implementation should make no difference.

Building and Running

The application will build only for a target that has a devicetree dev0 alias that refers to an entry with the following bindings as a compatible:

ambiq,mspi-device, mspi-aps6404l

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