CAN FD in S32k146

Hello community,

I am trying to implement a CAN FD system in my S32k146 board. It consists in sending to the board over CAN 0 and receiving from the board (to the CAN tool) over CAN 1. For transmission, when I am using a payload of 8 everything seems to be going fine. I send fine and receive fine as well. 

The problem comes when I want to send messages with a DLC>8, they are received by the board, and I receive back in my CAN tool the ID of the message, but not the data nor the message lentgh as shown in the picture.

For fixing this issue, I think that I need to put a bigger payload, so I select 16 or 32 or 64, but in that case, the system stops working, meaning that the board doesn't receive the messages anymore, and of course doesn't send back anything to the CAN tool.

Any help would be appreciated.
