Can you point me in right direction? I'm trying to enable CAN driver for olinuxino. I managed to compile and insert module from https://github.com/GBert/sunxi-can-driver. But no device appeared in /dev (no messages in dmesg also). There is sun7i-a20.dtsi file in this repo, but i don't know what should i do with it. Any help?
How are you using it, and is this something you'd be interested in sharing via a blog/wiki/whatever?

OK, i've figured it out. CAN works (:)

Nothing much to talk about. Just copied provided files, made some tweaks (as in example provided on github). Then "make a20-olinuxino-micro.dtb" and copied file to /boot/dtb- directory on microSD card. If you are interested i'll try to describe these steps tomorrow.

Is this CANbus you are speaking of? And does your board have a CANbus interface?
Yes it's CANbus. And it works OK. With Python it's a matter of three lines (:)
Would like to have one for my Cubies...
I'd like to run IP over CAN, but it seems impossible.

Oh, don't get me started. I was there in '94 for the USCAR CANbus decision and argued against it. My ideas would at $.25 per device and that was a non-starter.
There are CANbus overlays but they are very cludgy. There is CANbus-FM that will make overlays easier.
Better there is an IETF 6lo draft for BACnet IP. I would like to run that in a car, replacing CAN.
