Hereflow setup


I’m trying to setup the Hereflow on PX4 stable release on mini carrier board. I tried setting up the sensor as depicted here:

Only problem is I cannot switch to position mode. I tried unplugging the GPS and setting EKF2_AID_MASK=2 so that the position mode will only take the Hereflow into account but still the drone won’t accept to be put in position mode. When the GPS is unplugged, I get the ‘‘Primary compass not found’’ error. No error is displayed when I try to switch to position mode.

Is it possible the mini carrier board and the Hereflow are incompatible given it does not have a CAN 1 port? I tried connecting the Hereflow in both CAN 2 and I2C 2 ports.

Has anyone been facing the same issues?

Best regards,
