Hi Team,
We are connecting AR0531 and AR0821 which are 2-lane camera to Dev KIt of Xavier NX.
we are getting ‘3c’ address on i2c-bus instead of ‘3d’. Where We are getting correct address with AR0234.

sudo i2cdetect -y -r 12
0 1 2 3 4 5 6 7 8 9 a b c d e f

It’s depend on HW. You may checking with sensor board HW designer.

Hi @ShaneCCC,

But when we connect 2-lane to 4-lane connector it works fine.

I don’t think the MIPI lanes would change the slave address.
I would suggest consult with vendor and HW designer to check it.

Thanks
