VIO Showing the wrong value

[moo poo]

When I lift my VOXL m500(which has a VOXL Flight on it) up, I saw from "qvio" that the X-axis value is changing but the Z-axis value stays still. That shouldn't be happening, I mean I expect the Z-axis value changing.

I have checked the extrinsic.conf and configure the qvio again, the results remain the same.

Weirdly, with the same extrinsic.conf, another VOXL Flight(with a older system flash image) shows the correct value. Could it be due the system image since the "faulty VOXL Flight" uses the latest system image? Or other .conf files?
