NVIDIA jetson orin nano didin't send nack signal

I try to use NVIDIA jetson orin nano and raspberry pi to control a camera module by i2c.
When using NVIDIA jetson orin nano, i can’t see the address(when using “i2cdetect -y -r 7”), but raspberry pi can.
Then, I try to use “i2cget 7 0x33 0x00” to get the data. And I can see there are no nack and stop signal at orin nano, but raspberry pi have those signal.

Did you confirm the bus number?
What’s the BSP version?

4

Yes.
BSP version:35.3.1
When using “i2cset” can see the correct signal, but “i2cget” can’t.

Does raspberry pi work for that?

6

Yes!!

8

Which I2C port did you use? What’s the requested voltage level of your camera I2C? Did you probe the signal to check if that is correct?

9

I use bus7 (J12 pin3 and pin5).

3.3v

Yes, i saw there are no ack/nack after the camera send the data. Also there isn’t a stop signal.

Suppose the ack/nack is active by camera. Could you remove the camera module to confirm if any broadcast signal by i2c control while do the i2cdetect command.

Thanks
