Successful startup of Compliance Verification:

  • The first OPEN ALLIANCE TC8 Test Specification has been released
  • A complete test process over all OSI/ ISO layers has been put into reality.

Test setups are already finished to make the test process reality.

  • The Test Process has been successfully integrated into

OEMs boardnet development projects.

  • The first projects have been realized at the compliance test lab.

RUETZ SYSTEM SOLUTIONS has successfully executed tests against TIER1 components and TIER2 devices.

Initial considerations

  • How to get started as OEM?
  • How to get started as TIER 1?
  • What Test Scopes are important?
  • What about quality?
  • What kind of contribution

is desirable / necessary?

Physical Layer Findings:

Experiences

16

  • Signal integrity violations
  • Link up after power on too late,

caused by unsufficient aplication

slide-17
SLIDE 17

www.ruetz-system-solutions.com experts in automotive data communication

MAC Layer Findings

  • MAC Address incremented for every new frame transmitted
  • VLAN ingress filter does not distinguish between Tag Protocol

Identifier and Tag Control Information

  • Unsufficient switch configuration as root cause

to busload an security issues:

  • Forbidden VLAN tags and Ethertypes were not dropped
  • VLAN hopping possible due to wrong ingress filters for double tags

Experiences

TCP / IP

  • 3 way handshake timeouts
  • SYN-ACK too late (> 3sec!)
  • FIN-ACK not sent
  • Bootloader Flash Interruption

due to wrong configuration of

  • Congestion Control / Flow Control
  • Nagle Algorythm
  • Address management errors within:
  • Auto IP mechanisms
  • IP Addressing

Experiences

SOME/ IP

  • Ports not configured (ICMP port unreachable)
  • Subscribe with wrong port values
  • Timings (cyclic offer) not correctly implemented
  • Wrong Headers
  • Serializer not correctly implemented
  • SD state machines

not correctly implemented

  • Subscribe without offer

 cyclic ARP requests

The Compliance Process is up and running now!

  • It introduces standardized test methods
  • It converges new Automotive Standards to reliable systems
  • It provides an ecosystem for component and ECU verification
  • It eases the entry for new OEMs and Suppliers
