Design and implementation of a bootloader in the context of intelligent vehicle systems

Due to the growth of electronic complexity inside an intelligent vehicle system, improved diagnosis and reprogramming methods are currently researched and tested. In this context, a flash bootloader is the core of such approaches because it verifies the software's validity at each engine start and waits for an external reprogramming request. Further on, it offers the possibility of ECU reprograming inside the communication network of the car. This paper is presenting the steps needed to obtain a flash bootloader for an intelligent vehicle system and also offers insights into the performance of using such an application.
