If by Firmware Over-The-Air (FOTA) you mean updating device firmware wirelessly, you will get better help if you share some context, e.g. device/OS, MCU or SoC, flash/RAM size, connection type (cellular, Wi-Fi, BLE), bootloader in use, full vs delta updates, and any rollback or compliance needs. is right that the topic is broad, so here is a practical starting point you can adapt.

A minimal, safe FOTA flow:

  • Check for an update manifest over HTTPS or MQTT.
  • Verify the manifest signature before downloading anything (TUF-style metadata).
  • Download the image (or delta) to an inactive slot.
  • Verify the image signature, set a pending-boot flag, and reboot to the new slot.
  • Run health checks; if they pass, mark the update as committed. If not, auto-rollback.

Key requirements: signed firmware and secure boot, power-loss tolerance, rollback, rate limiting, and protection against downgrade attacks.

Good, concrete docs and patterns:

If you can share the device and constraints, folks here can point you to specific bootloaders, protocols, and code examples. Thanks to for moving the thread to a better spot.
