BBB CAN Baud Rate

[edwin...@gmail.com]

I have the Beaglebone Black tested and working on a CAN bus at 33.766k.  At the moment, I do not have a way to test different baud rates.  What other data rates would be acceptable for the Beaglebone Black?  Can the BBB communicate CAN at 100Mb/s or faster?

Thanks

I believe the CAN bus on the beaglebone is hardware limited to 1Mbit. Running CAN faster than that is pretty unusual.

CAN is fast, but not that fast. The maximum bit speed is 1 Mbit/s with the current standard ISO11898. The next generation, called CAN FD is expected to work up to 8 Mbit/s. In industrial applications a set of bit rates is defined e.g. for CANopen by the CAN in Automation (CiA). These bit rates are supported by Linux drivers like can4linux or SocketCAN.

What drivers/libraries have you used to get CAN working on the BeagleBone?
