Automotive Ethernet is a newly introduced in-vehicle bus that allows unicast communication between ECUs. It is based on the OSI model of Ethernet, with a few modifications on the physical layer and newly introduced application protocols. AUTOSAR, a consortium of automotive OEMs, Tier-1 suppliers and tool vendors has defined a standard software architecture that simplifies the ECU software development with its well defined software specifications and APIs. The Automotive Ethernet stack is now an integral part of the latest AUTOSAR specification release 4.2. Infineon Aurix TriCore TC27x microcontroller is a popular board used in ADAS applications. The board has support for Fast Ethernet. This thesis investigates the setting up of an Ethernet communication on the TriCore board running under AUTOSAR software architecture. The various modules of the AUTOSAR Ethernet stack are familiarized and configured. This is followed up by validating the implementation on the Ethernet physical layer. The validation is based on a real Ethernet communication between the TriCore board and the Vector VN5610 network interface card. TCP and UDP based connections between the AUTOSAR compliant board and the VN5610 are tested and validated. A test suite for evaluating the protocol conformance of the AUTOSAR Ethernet stack exists at Bertrandt. The final step of this thesis involved the execution strategies for this test suite.
