FAQ

How do I update the Raspberry Pi Pico SDK?

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 Raspberry Pi Pico SDK and record the version, date and changelog. If anything changed, subscribers watching this device get an email.

Is this an official Raspberry Pi page?

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