Hey all,
I've a BeagleBone Black here, and I would like to use
_both_ CAN interfaces of the SoC.
Does anybody know how to enable them?
I'm using the debian sd-card image from
http://beagleboard.org/latest-images
Best regards,
Florian

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:
