Here are my voxl-vision-px4 -o readouts;
There are definitely errors in the VIO data through the pipe, I just don't know how to fix it.If anyone has any ideas to fix this issue, I'm all ears

Could this issue be coming from imu0 and imu1?
-
Has anyone had this error message on their system?

From the Troubleshooting VIO docs, can you try these steps?
QVIO Overlay in voxl-portal
voxl-inspect-qvio -
@Chad-Sweet Yes, I have read through those steps and tried them. All of my cameras are viewable in voxl-portal. I have also ran the voxl-inspect-qvio and the status was ok with no error's.
-
Can you please share the output of those steps?
-

@Chad-Sweet What would you like to see in my voxl portal?
-
Here I have turned the drone about an inch to the left.

The qvio-overlay in voxl-portal is interesting, but from the voxl-inspect-qvio it looks like VIO is working properly. It's mostly likely PX4 is rejecting position mode, usually because it requires a magnetometer.
This section covers position mode rejected issues
Do you have a magnetometer connected? If not, are you sure PX4 is not expecting one?
-
@Chad-Sweet I haven't added anything special to my Seeker setup.
-
@Chad-Sweet
SYS_HAS_MAG
EKF2_MAG_TYPE
So, I should enter the 0 value for SYS_HAS_MAG
and 5 for the EKF2_MAG_TYPE? -
If you are using PX4 1.12 or later, and do not have a magnetometer, and want to use VIO, yes.
-
@Chad-Sweet OK
I’ll try that 
-
@Chad-Sweet There is not an option for 5 in EKF2_MAG_TYPE.
Should I leave this at “Automatic” or select “None” ? -
@Chad-Sweet I selected "None" for the EKF2_MAG_TYPE and entered "0" for the SYS_HAS_MAG.
The Odometry x y values are still at 0.

-
I unplugged the GPS from the Seeker. I am still not able to get position control in MAVLink and my Odometry x y values are still at 0.
Maybe the last option to do is to re-calibrate my cameras... -
If voxl-inspect-qvio shows functioning VIO data, there is no need to calibrate cameras. VIO is working. PX4 is most likely misconfigured.
If you have a GPS, then you likely have a magnetometer?
Seeker should have arrived pre-configured for VIO flight. No need to change anything. VIO is flight tested for 20 minutes before being shipped.
-
-
@Chad-Sweet
Yes, I have this GPS/Magnetometer that is on the back of the Seeker above the battery compartment.
If my PX4 is possibly misconfigured, should I just remove PX4 and start clean?
Or, is there something you might know that could be causing the problem in PX4?
