IA2	FlexRay 2.1

This course covers the FlexRay specification version 2.1

Objectives The course details the hardware implementation and describes the tests required to check the compliance of an equipment. The communication scheme which enables both Time and event-triggered communications is explained. The course focuses on error recovery mechanisms. Implementation examples are described through Freescale and Philips existing devices. A Lecroy analyser is used to capture and display FlexRay traffic.   •A lot of traces are included in the material. A more detailed course description is available on request at info@ac6-training.com

Prerequisites
	Experience of a digital bus is mandatory.
