MPU-9250 not detected

[gaultierq]

Running python pypilot/boatimu.py with a MPU-9250 plugged gives me No IMU detected, even though sudo i2cdetect -y 1 finds it on 0x68.
Moreover the output of
watch -n.1 python gyro.py
gives me some confidence that the MPU is healthy.

What version of rtimulib2 are you using.

I tried many, but mainly https://github.com/seandepagnier/RTIMULib2/

There is an example program in RTIMULib2/Linux/Drive This tests only rtimulib2 and uses no python. Make sure to delete the .ini file before running. Are you sure you don't have a system RTIMULib installed somehow? Can you try tinypilot image on your raspberry pi?

If you are in Raspbian you may have already installed rtimulib from another package, try:
sudo apt autoremove sense-hat

[gaultierq]

Apparently sense-hat was not installed.
I installed a fresh openplotter_v1.0.0.img and connected my MPU-9250/6500
trying RTIMULibDrive from /home/pi gave the same No IMU found
The python is working.

[seandepagnier]

What is the output? What does i2cdetect say?

It must be something in the code that considers your mpu9255 not to be detected. At this point I would get a working mpu9255, or single step the rtimulib2 code to find out why it doesn't detect the device on 0x68.

Logging the result value gives: 0x78 instead of 0x71 or 0x73
