FIRMWARE OVER THE AIR

Firmware Over The Air is a mechanism that facilitates firmware upgrades over the air, in the background, in order to push new features and configuration changes responsible for controlling the underlying hardware. The ECU, capable of FOTA updates, communicates with the FOTA gateway, which is connected to the in-vehicle network. The FOTA (Firmware Over The Air) system consists of three components: a FOTA server that manages vehicle software releases; a FOTA client that communicates with the backend server; and a FOTA agent that performs run-time firmware upgrades.

It’s vital to be able to update the operating systems of linked assets in order to keep them safe, introduce new features, and correct errors. The Internet of Things (IoT) has a lot of potentials, but it also comes with a lot of implementation challenges, including context-aware updates, connection concerns, security risk updates, IoT deployment scale issues, and recovery from interrupted updates. Firmware upgrades have become a standard component of IoT systems so that the massive number of connected devices remain updated and safe. Faststream has provided over-the-air (OTA) software updates for automobiles, medical devices, robotics, and more.

Today, automobiles have advanced to the point where they are incredibly clever. Instead of traditional mechanical components, the software now controls the majority of the vehicles. Software is becoming increasingly common in the automobile industry and accounts for a significant amount of the bill of materials. This rise, along with excessive warranty and recall costs, indicates that FOTA is inevitable.

Through OTA services, firmware updates and downloads for any of the car’s electronic control components are possible. As the number of ECUs keeps increasing in vehicles, sharing diagnostic and operational data from onboard systems may assist automotive manufacturers in improving product quality and operational efficiency, as well as providing post-sale vehicle performance and feature updates.

Software Over The Air

Wireless upgrades should be possible in modern automobiles. A connected automobile that cannot be updated remotely poses a significant cyber security risk. Automotive over-the-air updates have become the most preferred method for the distribution of everything from operating system security patches to infotainment system features and configuration changes or ECU updates.

High demands are placed on the reliability and security of the processes used for the task of updating the critical vehicle functions. Service-oriented communication in the Adaptive AUTOSAR has replaced the signal-based communication used in Classic AUTOSAR. This system architecture has made the integration of new applications into the entire system much easier. Therefore, adaptive AUTOSAR supports differential updates, while the classic AUTOSAR requires a full update of the application software.

Features of FOTA Updates for Remote Device Management :

• Information on device inventories, such as software versions, deployment sites, active devices, and more.
• Failsafe operating system (OS) upgrades are available via secure networks, preventing the bricking of devices.
• To assist with device management, sophisticated reports and analytics are available.
• User permissions, update time, update region, unattended/attended updates, and the utilization of network data are part of the update progress and configuration management.
• Device administration is based on device IDs (IMEI and SN), device groups, or campaigns on a broad scale.
