Hi, I’ve been trying to interface with some ODrive Pros through CAN and haven’t had any success. In all tests I used the default configuration, and verified that the can interface was enabled. I have also tried with both the termination resistor connected and disconnected.
Test 1: Using Linux Socket CAN, listening to the bus using candump received no messages. Verified that baudrates were equal. This setup had successfully been communicating to other CAN devices.
Test 2: Two odrives with their can cables plugged into each other with the same IDs (trying to force a “DUPLICATE_CAN_ID” error), no errors, n_restarts counting up on both boards
Test 3: Oscilloscope probe between CAN_L and CAN_H as well as CAN_H/L to CAN_GND, no signals observed.
I feel like I’m missing something simple here, is there an initialisation process that needs to happen such as a specific frame being sent on the bus?
Thanks in advance for your help!
