Hello Florian,
the problem is that the pins for DCAN0 are usually used by the I2C for the
EEPROM that contains device-tree informations for the beagle-cape.
So you need to disable the I2C device-tree automatism (if enabled) and then
assign the two pins to be DCAN0.
The best tutorial I've seen so far is here:

Regards,
Oliver
