Why I could not find Device address not found on IIC bus

I could Device address not found on IIC bus when I’ve CSI connected the camera to TX2 .(15PIN CSI camera:IMX219 )
I had add the driver of IMX219 to kernel.
The problem was that the camera device address could not be found on IIC bus
so sad.

What’s do you mean couldn’t find it on i2c bus?

You may need to check the sensor programing guide first.

I have recompiled system kernel with the camera sensor driver (imx219) but tx2 always could not Identify the camera device

Does the v4l2-ctl --list-device have any video device?
Did you implement your device tree?
