Overview

This document presents a step by step procedure for upgrading an M580 CPU, with a firmware version earlier than V4.01, to firmware version 4.01 or later.

To strengthen the firmware integrity check, the boot loader mechanism embedded in the CPU hardware has been enhanced. Consequently, loading the new boot loader into the CPU hardware requires a 2 step upgrade process.

To migrate a legacy CPU (firmware version 3.x and lower) to the newer firmware version 4.01 and higher, follow the 2 steps set forth in this document:

Step 1 - Upgrade the legacy CPU to migration firmware (LDX format) using Unity Loader.

Step 2 - Upgrade the migration firmware to the final firmware (SEDP format) using EcoStruxure Automation Device Maintenance (EADM).
