Hi all,
I follow a tutorial in interfacing BNO055 sensor.
It was connected to my Odroid C4 via SCL (pin 5) and SDA (pin 3) and also 3.3V & Gnd.
Ran command `sudo i2cdetect -r -y 0` returns shows the address to be 0x29.
Ran the launch file and errors showed up.

I have already edited the launch file, changing the device path to `/dev/i2c-0` and also the address to `0x29`.
Thank you.
Answer:
For `i2c device open failed`, run command `sudo chmod 666 /dev/i2c-0`
For `incorrect chip id`,Change the launch file address to
