GY-521 Calibration

[RonPeeters]

Maybe a not so intelligent question:
My IMU Calibration takes forever. And the value 16384 never decreases. Is this normal on the first calibration?

It's not normal at all
DMP Initialization Fail is not good.
Can you share picture of your wiring and jumper ?

Weird behaviour.

Measured 3.3v between vcc and ground.
I switched sda and scl. rebooted and got error connecting to MPU6050.
Switched back to original and now it seems to be doing something.

The issue keeps coming back randomly.
Initializing DMP fails then.

I have replaced cabling, without results.
So I have ordered a few new ones from the shop. Let's see if that brings any luck.

No need to share the wiring ;-)
The wiki is really clear on this, and also the text on the PCB1.4

I never test the PCB1.4 , but to be sure issue is on the IMU you can test the branch named MPU6050 on I2C1 and connect IMU on I2C1 port.
Normaly the I2C1 is directly connected to DUE without component between DUE and IMU

Thanks for the tip. Will try this, but I honestly think the fault is in the module.

I replaced the unit and the issue is gone. Thanks for the help.
