Sometimes, after a deploy or when the robot starts up, the ds keeps continiously repoting the following error while showing no robot code:
ERROR 4 [CAN SPARK MAX] IDs: 2, WPILib or External HAL Error: CAN: Message not found
(This is not only for id 2, every time it’s a different id)
The error keeps being reported until a redeploy, which almost always fixes it.
When I check said sparkmax it shows a can fx and rx sticky fault
Why might this happen?
I am pretty sure I’ve ran into this issue before and IIRC it was a communication issue (thus the can message not found) I’d check and make sure your can wires are well connected. Also, what is the light pattern on the problem spark max?
I know when we had issues related to the SparkMax with error codes like that it was because of a faulty REV Pneumatics Hub breaking our can chain. I also would say blink codes are more specific in what may be wrong with the Sparks.
I don’t think I saw it changing from the normal blinking pattern (cyan / purple blinking depending on brake / coast)
We don’t have a pneumatics hub but we’ll be sure to check all the can connections again
