Bringing Can interface up - Operation not supported

Question

I am trying to use a Can module but I get an error message with the following commands:

$ sudo modprobe can
$ sudo ip link add dev can0 type can
RTNETLINK answers: Operation not supported

I have checked the Elinux documentation related to CAN interfaces and the procedure works with the virtual interface

$ sudo modprobe vcan
$ sudo ip link add dev vcan0 type vcan
$ sudo ip link set up vcan0

Do you have any advice?

Answer 1

I am using a can bus module which communicates with a Raspberry Pi using SPI.

I had to enable the spi hardware interface:

dtparam=spi=on
dtoverlay=mcp2515-can0-overlay,oscillator=16000000,interrupt=25 
dtoverlay=spi-bcm2835-overlay

Should be:

dtoverlay=mcp2515-can0,oscillator=16000000,interrupt=25 
dtoverlay=spi-bcm2835
