3. DA1470x

3.1. Tutorials

This guide is intended to help customers setup the hardware development environment, install required software and download and run an example application on the DA1470x development platform.

This document describes the architecture and usage of System RAM memory in DA1470x. It gives an analysis of the way a project configures the system’s RAM through linker scripts and the way changes are made according to custom needs. DA1470x SNC template project is used as an example. Finally, the mem_report python script is also presented and used on the example project, to verify the result of the changes.

The DA1470x is a family of multi-core wireless microcontrollers, combining the latest Arm Cortex M33™ application processor with floating-point unit together with a dedicated sensor node controller. It also provides advanced power management functionality, a Display Controller and a Graphic Processing Unit (GPU), a cryptographic security engine, analog and digital peripherals, and a software configurable protocol engine with a Bluetooth® 5.2 low energy radio. This document focuses on the operation of the Voice Activity Detection (VAD) engine of DA1470x. It describes additionally how the VAD can be combined with a voice recognition engine from Cyberon to support a complete hot word detection solution for predefined commands.

This tutorial aims to provide an in-depth analysis of the secure boot feature on the DA1470x Bluetooth SoC.
