I need help for setting the STM32H753 FDCAN as Calssic CAN with Simulink

Moved from this thread.

Hi TOlli,
Hope you will see this message. I'm having trouble using FD CAN communication as simple CAN with the NUCLEO-H753ZI. I use Simulink to create my program and it gives me error when I select the "Classic Mode" for Frame Format, asking me to choose between the other two modes. Using the "not BitRate Switching" I managed to succecfully communicate with a NUCLEO-F446 with CAN, but unfortunately the NUCLEO-H753ZI doesn't receive the CAN message from the NUCLEO-F446.

I'm using for both devices two CAN/FD CAN lines to check that the messages are transmitted correctly.
Do you know how I might solve this problem?

Thanks for your time,

Giaggio
