Thanks for that William. Very handy information. Do you know if anyone
made it work on BBB yet?
I will try that soon I hoop.

The last time I looked, the there was already a kernel driver for this
CAN device.
http://lxr.free-electrons.com/source/drivers/net/can/mcp251x.c?v=3.14
is just one such example for the 3.14.x kernel, but that does not mean
you *need* 3.14.x kernel for it to work.
Anyway, I know several people have gotten this chip to work on the rPI
- Since I googled this chip a couple months ago to see what all was
done with it in Linux. At minimum you should have many things to go by
from the rPI camp. Most of the setup / usage should be similar.

I have a feeling that you will have to change the low level driver
code to include the SPI mechanism. Can is not just a protocol but
there is a lot of bus arbitration type of actions at low level.
I wonder if it would not be easier to look for a high level protocol
that can be piped to any comms driver or even roll your own.

Hey! Just like the title says, I'm interested in doing this. I know I
can use the CAN bus on the Beaglebone, but I want to be able to do it
over SPI. Anyone ever tried this before?
