This session introduces eSOL’s Full Stack Engineering approach to enabling SDV development, using OTA solutions as an example of a key technology in this field. It also presents practical methods for developing FOTA and reprogramming-capable ECU software using the AUTOSAR-compliant in-vehicle platform AUBIST, the ECU reprogramming module Dr. Repro, and partner products. In particular, the session focuses on methods that use UCM (Update and Configuration Management) as defined in the AUTOSAR specification, illustrated through real-world examples.
