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

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)
