Overview

This user guide provides technical instructions for implementing the IEC60730B Safety library on NXP i.MX8M Mini and i.MX8M Nano application processors. It details hardware configurations for the EVK-MIMX8MM and EVK-MIMX8MN evaluation kits, including switch settings for eMMC and QSPI flash booting. The document explains the integration of safety middleware within the MCUXpresso SDK and provides step-by-step procedures for building and debugging example applications using IAR, Keil, and MCUXpresso IDEs. It also outlines the execution of specific Class B safety tests, including CPU core registers, RAM, Flash memory, and digital I/O (DIO) peripheral testing.

Use Cases

  • Developing IEC 60730 Class B compliant software for home appliances
  • Implementing functional safety routines on i.MX8M application processors
  • Configuring safety self-test libraries for industrial control systems
  • Setting up hardware evaluation kits for safety-critical embedded applications
