Hi Everyone,
I am looking for information on how to use the CAN driver for the MPC5200b. I have built the kernel (2.6.27) with the MPC5200b can bus drivers and I see them being initialized on start up.
[ 37.122041] can: controller area network core (rev 20071116 abi 8)
[ 37.128687] NET: Registered protocol family 29
[ 37.133379] can: raw protocol (rev 20071116)
[ 37.137807] can: broadcast manager protocol (rev 20080415)
Do I have to define a UDEV rule? Has anyone already written a rule to make the can driver visible in /dev?
Any pointers or snippets of code would be greatly appreciated.
Nick

I'm pretty sure this is just the SocketCAN interface.
You still need a hardware driver (and one which is SocketCAN compatible).
I don't see such a driver for the MSCAN (the hardware on the MPC5200) in
the stock 2.6.27 tree.

The drivers for MPC5200B's mscan are still in the SocketCAN repository,
right. The team is working on getting the patches ready for mainline.
