booted up and got this warning. Never seen that before. Wasn’t asked for any calibration and all sensors, gpd were solid. Turned off and turned on and didn’t come back. Ideas?
IMU redundancy switch?

I'm thinking more, dilithium crystals ~ but it could be the capacitor. Get it up to 88 MPH and see what happens. Seriously though, I've never seen that before on any of my DJI drones. That's an odd one.
The Mavic has dual IMU's for redundancy as a failsafe as well as 2 compasses. If one of your IMU's is misbehaving, it will automatically switch to the other, but whenever I see that message, it means that the drone is relying on a single IMU, and its best to land asap. Sometimes the culprit is the accelerometer.
Also, best to do a full calibration including IMU, and other sensors and see if the error comes back. If so, it might be a mechanical problem and will need to be addressed.

That’s what I’ve read. It was still in my hand as I hand launch and land. I hold it for a min or two to let all the connections get made. Controller with iPhone was under my arm but not sure why this error would come up without even taking off
Is it an indicator of an underlying problem or likely just a one time glitch?
The IMU's are responsible for various functions, and sometimes need a little while to initialize after power on. I get the IMU initializing message alot, but it usually goes away if the drone is untouched until the IMUs have gone through their routine.
You will have to be the judge of that. If it happens repeatedly upon startup or ever happens in flight, and you are under warranty, I would send it in.
Ya I hold and let it get gps lock, watch for compass calibration, check sensors and do the compass Facing check. About 1 min after power up that message fired up. So not sure what caused it as it had to errors anywhere, never took off. More worried about something on the inside acting up or just a fluke error?

Thunder ~ could moving the drone around in your hand during its boot-up cause issues with the gyros or IMU? I remember on my P2, I had to leave it pretty still on the ground during boot, or it couldn't figure out which way was up.
Wonder if it’s related to latest firmware. I’ve done well over 200 flights with the air, 90 percent hand land and launch. First time
I’ve seen this error

Yes absolutely. Sometimes when I start a drone I get an IMU message and it says "IMU Initializing. Do not move aircraft until initialization is complete." Sometimes it takes a few seconds and on some drones alot longer.
I hit up support just to let them know I
Got it. Will refresh firmware today and calibrate IMU from dji assistant

I asked this question, as I was wondering if the OP, @Jameslavis, who says he hand launches/catches, might be holding the drone while it's initializing.....?
Ya always. I’ve basically done all my take offs and initial Turn ins while in hand. Sure there is a chance it was maybe tilted or something covered. Just funny how 190 flights in and this happens.
Thats exactly what I was thinking. The drone really needs to be started on a level surface until all systems have been initialized. Hand launching is one thing, but it should be started on a level surface first before launching.
After 190+ hand launches, my hand would be shaking too
It shook more when I put it up the first few times! Pricey investment. Will initialize flat and see if it comes back
