I am trying to interface with vehicle engine using Intel EG20T chipset.
This board does have a pinout for CANbus interface, and I believe I have
determined the correct module for the interface is pch_can
http://cateee.net/lkddb/web-lkddb/PCH_CAN.html
Someone told me I may need the i2c module for this chipset as well, so I
have loaded it also (i2c_eg20t)
I have loaded the modules for the can interface (can, can-dev, can-raw,
can-bcm) along with i2c_eg20t and pch_can.
dmesg | grep can reveals
can: controller area network core (rev 20120528 abi 9)
can: raw protocol (rev 20120528)
can: broadcast manager protocol (rev 20120528 t)
but nothing is listed regarding pch_can and the interface can0 is never
listed.
dmesg | grep can0 gives no result and cat /proc/net/dev lists p2p1 and
lo but no can.
can-utils have been built and installed and appear to be working
correctly (although I cannot test without a can interface really)
What am I missing?

I have made some advancement and now have the interface detected but
can't seem to bring it up.
