Link Problem with BroadR-Reach/100BASE-T1 PHY

Here you find some hints that will help you to solve the Link down problematic:

1. No link can be set up / Link down is displayed in CANoe Trace

How are the two devices connected to each other?

  • Both lines (P/N see VN5610 manual) must be connected correctly, namely P with P and N with N.

How is the master/slave configuration selected?

  • For BroadR-Reach/100BASE-T1 & 1000BASE-T1 you need a Master and a Slave. If both PHYs are configured identically, no link can be established.

2. A link cannot always be established when disconnecting and reconnecting the cable between the VN5610 and the ECU

  • This problem was solved in driver version 9.8. Which driver version does the customer use? Update drivers, if necessary (see Download Center).

Note:
If these hints do no help you further please send us a description of your issue together with a Configuration Report like indicated in KnowledgeBase article Necessary Data to Analyze HW Problem.
