To reduce the vehicle downtime because of a running OTA update, parts of OTA update process shall be executed during normal operation of ECUs, e.g. while driving. While the current SW is normally executed, the new SW shall be installed in the back-ground.
FOTA Target ECU shall support diagnostic services dedicated for image updates in normal application mode. This is mainly about securely accessing the ECU, erasing dedicated memory parts, requesting to start the installation of the new image, transfer of data and triggering the verification procedure at the end of the transfer.
SBL is a second bootloader used with the FOTA-capable firmware. It manages the update period by verifying and writing the new firmware image to the designated area of internal or external storage devices. SFW is based on FreeRTOS and is designed to implement a complete FOTA process together with SBL.

2023年5月23日 · FOTA updates allow a device's firmware to be updated over a wireless ("air") internet connection. The best way to understand the intricacy of a software update using FOTA is through a diagram: Image: Over-The-Air software update process.
AN229058 explains the different steps involved in developing a secure and reliable Firmware Over-The-Air (FOTA) update in TraveoTM II MCU.
The SFW is based on FreeRTOS and is designed to implement a complete FOTA process together with the SBL. The SFW supports to obtain new firmware image through U-Disk and SD card locally, and remotely through the AWS cloud or Alibaba Cloud.
RSL10 FOTA - Firmware Over the Air - onsemi
Before performing a FOTA update, a developer must first create the new firmware image. The RSL10 SDK provides the tools and sample code to develop and generate a FOTA capable firmware application. Using a mobile phone to perform FOTA is not the only way. FOTA can also easily be performed from a PC.

An embedded systems-centric Firmware Over The Air (FOTA) solution utilizing Raspberry Pi, Firebase, and Embedded Linux for efficient remote firmware upgrades Resources
Open Mobile Alliance (OMA) has set standards for FOTA. This paper presents a review of such existing standard protocols and schemes for FOTA. The short comings in existing techniques are identified and the issues are addressed. Keywords: Connected vehicle, Firmware-Over-The-Air, Internet-of-Things, Open mobile alliance. 1. Introduction.
What is FOTA? How to update firmware over-the-air? - Hexnode
FOTA is a mobile software management technology that enables the updating of a mobile device’s operating system. The download process for FOTA-capable phones is typically less than 10 minutes. FOTA simplifies the process of updating mobile device firmware by allowing manufacturers to provide it through a single, secure and fast method.
