I can't get my CAN bus application (ISO 11898-2, classic "high speed CAN") working and I'm receiving various CAN error frames. These error frames manifest themselves as sequences of 6 bits with my selected bitrate, either high or low. 

Alternatively there is a "bus off" error and nothing works at all - my CAN node is completely silent.

What are the common causes of communication errors and error frames in a CAN network/CAN application and how do I solve them?
