Abstract
Embodiments described herein provide a method for an error logging mechanism operated with controller area network (CAN) buses within an Ethernet network. A first interrupt request indicative of a first error condition that occurs at the first CAN bus is received at an Ethernet bridge and from a first CAN controller connected to a first CAN bus. In response to the first interrupt request, the first interrupt request is serviced by retrieving, from a first error register at the first CAN controller, information relating to the first error condition. The information relating to the first error condition is encapsulated in a first frame in compliance with a layer 2 transport protocol for time-sensitive applications. The encapsulated first frame is then sent, via an Ethernet switch, to an error logging device installed at a location remote to the first CAN bus.
