I'm thinking in replace a STM32F7 with a STM32H7 on two board that has normal CAN-2.0 transceivers. I would like to know if it will work for CAN-FD frames, keeping the baud below 1 Mbps.
Both CAN modules (FDCAN1 and FDCAN2) are compliant with ISO 11898-1 (CAN protocol specification version 2.0 part A, B) and CAN FD protocol specification version 1.0.
This is what we say in STM32H7 datasheet.
So, the configuration you want to setup for FDCAN should work properly.
You can also refer to AN4936 (Migration of microcontroller applications from STM32F7 Series to STM32H7x3 line microcontrollers) for more hints when migrating from F7 to H7.
