Thank you for your reply.
After I connect I2C_0 to TCA9534,i2cdeteclt -y 0 did not capture the device address 0x38, I want to ask is need to add a new device tree node about TCA9534 in the device tree I2C_0, if I want to add, then in which file to add? Modify the device tree of orin nx, which file is modified?
Thank you

it’s could using DTBO, i.e. device tree overlay to register the camera module.
or, you may To register a device using the main platform device tree file.

I can’t see the device address of the TCA9534 through i2cdetect-r-y 1 on orin nx and nx, but I can see the signal on SCL and SDA。 I don’t know what‘s the reason。Can you help me.

Sorry for the late response, have you managed to get issue resolved or still need the support? Thanks

OK,I switched to another chip, and the device can recognize the address. And the new chip is already working.

Hi，kayccc
I used PCA9654, and this chip works normally, meeting my expectations.
