GMSL cameras on different PX2 boards cannot work together

We found a tricky problem today. We have two PX2 in the office and connected to the Internet with different IP addresses. When both of us try to run ./sample_camera_gmsl, both of our cameras cannot be connected. But when either one turned off, the other one’s camera is working. Not sure what happened to this? Is this because of stream something?

Also,Is that possible to get the GMSL camera ID or similar information to work with openCV capture function? Thanks!

You need to change the IP address of the AURIX on one of the devices since the AURIX is what controls the power to the cameras. The file on the tegras is in /etc/tacp but you also have to change the IP on the AURIX using the serial console.
