says that there is a

handles the CAN FD controller.
The ATSAME70N19 is connected somehow to the Intel Atom-Prozessor E3805.
So I won't assume, that you can access the CAN controller from the Intel
CPU.
I tried to set it up but get the following error

RTNETLINK answers: Operation not supported
You can not "add" a real CAN interface with "ip link add ..." - this
works only for virtual CANs.
Try
ip -det link show
where some CAN interface (e.g. can0) should be visible, if you have one.
