I'm using DJI Assistant 2 for Autopilot to program my N3 flight controller and it will not recognize the compass. We've tried re-loading the firmware (v1.7.7.0) and downgrading the firmware and the update always fails. There is a "PMU Error" at the bottom left of the update.
Any ideas? Is the compass not being recognized a function of a broken PMU? If so, this will be the second module we've bought where the PMU appears to have died. How do we get a replacement PMU?

Thanks - Joey
