Hello Jetson community,
I’m encountering an issue with a board I’ve developed for the Jetson Nano. Everything on the board (e.g., other ports and interfaces) works fine; however, in the CSI section, although I expect two outputs, only one (video0) is available while the other does not appear at all. Additionally, I am using the TCA9548A chip as an I2C mux.
Detailed Information:

Note: The publishing code above gives an error while streaming video. When I stop and restart it, it freezes
Although it detects video0, I can’t stream from this port. In fact, I am facing two problems:
- It doesn’t detect the second CSI port; it only recognizes devices connected to one of them.
- Although video0 is visible, I can’t stream video.
I used an oscilloscope to monitor the SCL and SDA pins of the TCA9548 chip, but I only observed signal activity on port 0 of the chip
Does anyone with experience or suggestions have any insights on how to resolve this? Your help would be greatly appreciated. Thank you!
