CameraServer is lost on code deploy to roborio

[bruingineer]

Everytime we deploy code to the roboRIO, the CameraServer does not show up in network tables. After a power cycle of the robot, the camera server shows up again.

Has anyone seen this behavior before?

in robotInit():

var cameraName = "mmal_service_16.1";
camera = new PhotonCamera(cameraName);

I solved this by adding

var cameraName = "mmal_service_16.1";
if (camera == null)
        camera = new PhotonCamera(cameraName);

to robotPeriodic() or similar

We are still getting

PhotonVision coprocessor at path /photonvision/mmal_service_16.1 not found on NetworkTable!

in our robot log when we deploy code to the robot.

It resolves itself on a robot power cycle.

We have also experienced this issue as well. It appears to be very inconsistent on when it appears.

We're seeing this as well. Restarting photon or unplugging/replugging our coprocessor seems to be a working temporary fix.

Is this issue still happening?

var cameraName = "mmal_service_16.1";
if (camera == null)
        camera = new PhotonCamera(cameraName);

to robotPeriodic() or similar

I would need to see more of your code implementation to trace an issue here. It could be in your robot code or the backend not publishing data to NT
