Subject: Re: Enable both CAN interfaces of BeagleBone Black

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
