Xavier camera i2c issure

Hi, guys:
I am working on Xavier’s camera. When i use i2ctool “i2cdetect -y 3” to check i2c3 which is use to camera, the dmesg shows timeout. And i2c5 either. Whats problem with my i2c?

if you used the camera connector of xavier(J509) it’s i2c3,but i think you should check your i2c device used:sudo i2cdetect -r -y 2
