Zephyr OTA Firmware Updates and Device Management

Make Your Zephyr IoT Product Update-Ready

A connected product is not truly production-ready until it has a disciplined firmware update path.

This course takes the next step.
You will learn how to add professional firmware update capability to a Zephyr product using MCUboot, signed images, image slots, firmware versioning, rollback behavior, MCUmgr workflows, update diagnostics, and release-ready update discipline.

Why This Course Matters

Connected devices are expected to live beyond the first firmware image shipped to the field.
Bugs must be fixed.
Features must be improved.
Security issues must be addressed.
Configuration and compatibility problems must be corrected.
That means serious embedded products need more than connectivity. They need a safe, repeatable, testable update process.
This course teaches that process inside the Zephyr ecosystem.

By the end of this course, you will understand how to make a Zephyr-based IoT product update-ready.

You will know how to build signed firmware images, manage image slots, test firmware updates, confirm successful images, observe rollback behavior, report update state, and package a professional update workflow.
If the main Zephyr IoT course teaches you how to build the connected product, this course teaches you how to update it.
