ECU OTA Software Update Development

Developing ECU OTA (Over-The-Air) software update capability is a complex but essential task in Software-Defined Vehicles (SDVs). It enables secure, remote updates of ECU firmware, application software, configuration files, or even bootloaders — without requiring physical access to the vehicle.
This feature improves serviceability, enables new features post-sale, and reduces recall costs. It requires close coordination across bootloaders, diagnostic protocols, secure communication, campaign management, and fail-safe mechanisms.

ECU OTA Software Update Development

Here is a structured breakdown of all major components and steps:

  • Bootloader Development (Flashing Core): The bootloader is a small software module that initializes the ECU in a minimal mode
  • UDS/DoIP Diagnostic Support: ECUs use the UDS protocol (ISO 14229) over: CAN or Ethernet
  • Software Package Preparation: Prepare update images in a secure, encrypted format.
  • Security Infrastructure: Secure the whole software update process
  • In-Vehicle Update Orchestration: n connected vehicles, update control and orchestration.
  • Vehicle-to-Cloud Communication: Requests updates, downloads packages from the cloud and respond the update status
