How to update the RIOT IoT operating system

Read the release notes first — firmware changes can require re-doing your config or calibration.
Use the project's own installer where it has one: a web flasher over USB, or an over-the-air update in its web UI.
Otherwise build or download the binary for your exact board from the releases page — the wrong board file will not boot.
Keep the previous firmware image and your config backed up so you can roll back.

Always download firmware from the manufacturer or project itself. Firmwarely links out; it never hosts firmware.

FAQ

How do I update the RIOT IoT operating system?

See the step-by-step above. Follow the project's release page for the flashing or OTA procedure. Many maker devices update from a web installer or the project's desktop app.

How does Firmwarely know when there's a new version?

Every night we read the manufacturer's official release page for the RIOT IoT operating system and record the version, date and changelog. If anything changed, subscribers watching this device get an email.

Is this an official RIOT page?

No. Firmwarely is independent. Device and brand names belong to their manufacturers; always download firmware from the official source.
