CPU and EKF error

Having an issue with a rig that is flying erratically.

What is the meaning of the error, err:cpu-1, err:cpu-0


And what is the meaning of the error, err: EKK_CHECK-2 and err: FAILSAFE_EKF-1?

Any suggestions on troubleshooting what is happening would be most appreciated. Log files are here

Cheers,
Tim

@gmorph Grant, here is the issue(s) I was referring to.

Is there a different forum to be posting this to?

This setup has at least 60 missions with this config/setup. It began with an erratic flight, and then the accel and compass were re-calibrated, and no luck.

Thoughts?

This is what lead me to create the other post related to log analysis. Thanks for the links as well!

Cheers,
T
