Automotive FOTA Software Development

Firmware Over-The-Air (FOTA) lets OEMs update ECUs without a workshop visit. Embed IO provides automotive FOTA software development, from the secure bootloader on the ECU to the update flow between the vehicle and the backend.

Bootloader components are part of our software component portfolio for customer integration.

What We Deliver

  • Firmware Over-The-Air integration for automotive ECUs
  • Secure automotive bootloader development and porting
  • UDS-based FOTA update flows
  • Update orchestration with telematics and gateway units
  • Cybersecurity requirements, including those derived from ISO/SAE 21434, considered during design

How an Update Works

  • The update package is delivered to the vehicle through the telematics unit
  • The gateway routes the package to the target ECU
  • The bootloader verifies and flashes the new firmware
  • The ECU reports status back to the backend

Why Embed IO

  • Turnkey embedded hardware and software development under one team
  • Experience across automotive ECUs, connected systems and industrial embedded products
  • Flexible engagement: fixed-scope projects, dedicated engineers or on-site support
  • Chennai-based engineering centre working with customers across India and globally

Frequently Asked Questions

FOTA is the delivery and installation of ECU firmware updates wirelessly, without physically connecting the vehicle to a programming tool.

A secure bootloader is the ECU startup and flashing software that verifies the authenticity and integrity of new firmware before installing and running it.

UDS defines the diagnostic services commonly used to request downloads and transfer data to an ECU during a firmware update.

UNECE Regulation No. 156 sets requirements for software update processes and software update management systems in vehicles. It requires manufacturers to manage and document updates, including those delivered over the air.

The bootloader checks the integrity of the received image, for example with a checksum, and verifies its authenticity, typically with a digital signature, before it erases or writes memory. If verification fails, the update is rejected and the existing firmware is kept.
