IMU initialisation (warm up) is part of the normal start-up process. Depending on the ambient temperature when the IMU was calibrated, the 'warm up' period can be a few seconds to almost a couple of minutes. Nothing to worry about though.

Usually I won't get gps safe to fly while the Imu is warming up. That's what was weird

I am have the same issue. I have the green GPS indication after the yellow IMU warmup flag. The first flight goes well. I land, put a second battery in and viola! Can't go anywhere. When I attempt to start the craft, I get a sliding 'warning' that says, "IMU Initializing. Do not move aircraft until initialization is complete."

I've brought the craft inside, let it sit for half an hour, started up as normal, and same result.

I've already checked for firmware updates and there are none, I'm up to date.

Anyone else?

Had the same problem.

It seems fixable by doing the following:
1. Startup Aircraft & Remote
2. go to "Menu" (top right) -> Aircraft button (in the menu the uppermost button) -> "Advanced Settings" -> "Sensors State" -> "IMU Calibration"
3. When done (can take UP TO 10mins!) -> "Check IMU"

After that, you should be able to fly again
Please get back to me, if it did work or not!

Cheers

Just wanted to thank amrun for the walk through.  I'm calibrating now and I hope this problem is resolved... there's a really huge buck wandering my area and I'd like to do a fly over observation to see where he hangs out.

Happened to me today for the first time on my Phantom 3 Advanced. . .almost 2 years old. .weird thing is I already had it up in the air, came down, switched batteries, fired up, green light to go/GPS acquired, attempt to start props and get the IMU Initialasion (yes, initialisasion was misspelled). . .shut down everything, ac/rc and phone, restarted, placed the aircraft in a different position in case there was any interference, and I was able to fly after that. . .thought it had something to do with the battery. . .hmmmmm.  .just an FYI. . .

hope when you did the re-cal, that you set the AC over your home Air Conditioning vents or put the craft in the fridge.
Lots of users have said they did that, and after the calibration was done, they no longer have a large wait time for warm up.  
As the craft is already warmer than when you did the cal.

Bonjour, j'ai un problème de calibration imu. Lors du calibrage il affiche " systeme temperature too low " et la progression se bloque à 10 ou 15%. Je n'ai pas eu de crash. Il volé parfaitement bien. Lors d'un vole il a affiché interférence compas.

I want to thank amrun for this fix.  I am new to drones and bought a used Phantom p3 from a friend.  I flew it a couple of times and then another day got this error.  I remember doing the calibration on a hot day.  On the day of the error it was rather cool and would not start up.  After doing this fix, everything was fine.  KUDOS!

Tried this today (you have to use the DJI app, this isn't an option in the Litchi app), but to the point, this worked like a charm! Thank you!

Va au menu en haut à droite et choisis l'appareil et descend en bas et choisis 'sensor state' et presse sur IMU calibration et ensuite  à Check IMU
