How can I test and view the CAN bus mttcan error counters?
We have a custom carrier board with a TCAN1043 CAN bus transceiver. We are able to send and receive data, but have not seen the error counters increase from 0.
I want to verify that the error counters work (as shown with ifconfig can0).
I’ve tried grounding CAN_H while sending/receiving CAN bus data, but the error counts shown with ifconfig stay at zero.
Is there something else I need to do? Our CAN bus analyzer doesn’t support inserting bad CRC or error conditions but we will get one with more features if necessary.
