I have actual Flexray log from a car and the hardware to read/write to the FR bus. Let me know if you need any help.

@TheMutley The Flexray log is definitely helpful, can you send the log to me or share it on slack? I'd like to do some analysis and share the result.

@nanamiwang , in 2-3 months we will do a openpilot port to a car that uses FlexRay (we have a nice Cadillac CT6 :)), possibly by leveraging this work. So that would be a way to verify this PR and unlock the bounty. Alternatively, any verification from the community would also be ok.

@rbiasini this is ok for me, take your time. I am trying AUDI A4 porting to verify my work.
BTW, a question, why the official AUDI A4 porting bounty is removed? Bounty will encourage me to work more time on this.

Ah, yes, we removed it 8 months ago. It was probably removed because we bought the CT6 and we plan to do the port ourselves. I can put a bounty back, specific for Audi.

This would be so useful. Does anybody have a clue where to look for a flexray socket in a car? I believe I have 2 cars which should have one, I just have no idea where.

Verification will be done with my A4 :-D

There is no standard flexray socket in a car. You have to look at wiring diagrams at your car.

Anyway, I don't think that this place is the right one to speak about such things (offtopic). Please join us at discord. Thank you.
