Hi, I have been using Adafruit IMU (Adafruit 9-DOF Absolute Orientation IMU Fusion Breakout - BNO055 : ID 2472 : $34.95 : Adafruit Industries, Unique & fun DIY electronics and kits) with Jetson TX2 and it worked very well. Now, I am trying to use it with Xavier NX but it did not seem to work. The imu was linked to NX by GPIO i2c pins. I use the pin 27 and 28 for SDA and SCL, which are for bus 1. However, when I do

sudo i2cdetect -y -r 1

It did not show anything.

Can anyone help?

You may need to probe to confirm device have ack.
