CAN FD Shield on CAN 2.0 networks

Hello.

I just bought a 2CH CAN FD hat for raspberry pi, and did not realized they were FDs.

Is there a way to make them work on a CAN2 network, on automotive environment? With the regular instructions I cant seem to make it work with the other devices. Nothing is recieved or transmitted (250Kbps).

Thanks.

Of course, FD is compatible with the CAN2.0 protocol.
