CAN transmission works well at SDK02 but does not work at SDK03

[kimjunghyun]

Hi.

Recently I made CAN message transmission code and it worked well. I confirmed it on the CANoe

* I had some problems so I asked here and PetrS helped me so I could handle it.

  The problem was clock.

But after I updated S32DS, this code did not transmit CAN message.

* Of course I changed all components which I used from SDK02 to SDK03.

So I made another new project and I used same code. But CAN transmission did not work.

* Digital input and output worked well.

* CAN related functions executed during debuging (I checked it)

Why this code do not transmit CAN message?

MCU : S32K144_64pin

TX : PTC7(51pin)

Hello,

this question is very similar to your second question posted in this thread:

https://community.nxp.com/message/885252 

I sent question to SDK application team and I am waiting for answer. I will write you the answer to the second thread as soon as I have any information for you.

Regards,

Martin
