Hereflow UAVCAN not working

Hello everyone, I’m trying to get the hereflow to work but I’m getting an error -13. I just connected the hereflow to can1/2 and set UAVCAN_ENABLE=2 according to the manual.

Dmesg is showing:
WARN [uavcan] CentralizedServer init: -13
WARN [uavcan] Node init failed: -13
ERROR [uavcan] Firmware Server Failed to Start -13

uavcan status is showing multiple sensor drivers to be active but no online node is shown.

I checked for SD card issues and reformatted to be sure, but nothing helped.

I’m using the latest stable px4 stack (PX4 Pro Firmware v1.12). I tried multiple pixhawk-cubes of profiCNC (orange, black) with different carrier boards (normal, mini). In every configuration I’m getting the same error.

Does anyone have an idea of a possible root cause?
FYI: I have also posted this on Hereflow UAVCAN not working - PX4 Autopilot - Discussion Forum, for PX4, Pixhawk, QGroundControl, MAVSDK, MAVLink

@philip could you point me in the good direction or do I need to request an RMA?

Can you try to setup on Ardupilot, just to verify if it works there?

Dear Alvin, Will do that this weekend.

Best Regards,
Tim
