MPC5744P FlexRay POCSTATE NORMAL ACTIVE can not change

[Ada_Lovelace]

Hi,All

I want to test FlexRay in MPC5744P， I use demo code in community,  I use two boads to Node1 and Node2，but  when I test it ,FlexRay is  always in startup, it can not change to normal active.

The file Application is the demo code, I put it in  MPC5744p，FlexRay_For_Node1 and FlexRay_Fo_Noe2 is the MPC5744P's test code.

I use DEVKIT-MPC5744P and MPC5744P-257DS to test Node1 and Node2.

What should I change to make it work?

Hello,

We have tested your code and it is running correctly on 2 boards of revision E. (we do not have here revB).

So there could be possible issue in jumper settings (please check all the jumpers).

Or there could be issue on RevB board ( we will check that if we are able to find the board here).

Possibly there could be issue in code using 2 flexray channels but on revB there is only 1 (on revE there are 2)

But even if we disconnect 1 channel the code was still running correctly.

Best regards,

Peter

hi,Why is your test OK？i used the code in my project,and The same problem has arisen。

what can i do it in this code?

Hi，Peter

I have only two boards, one for  revB, one for 257DS, I will check my boad ,and you mean the code is running well, it means code don't have problem.

Can you tell me how to do test FlexRay for two boards?  I need to check every step to find the problem.

I want to know  if my test method is wrong.

Thanks.

Hi ,I used your code, and the same problem occurred ！Have you solved the problem?

[Ada_Lovelace]

I do not solve it yet, which board do you use? 257DS or Rev B?
