[ROS2] Multiple cameras not working on Jetson Orin

[JulioPlaced]

Hello, We are using two Blackfly S GigE cameras connected to a Jetson Orin AGX (Ubuntu 22 & ROS2 Humble) using a switch (since the Orin only has one ethernet port). The two cameras are correctly configured and we can see both of them at the same time using Spinview.

However, when we launch the driver, only one of the cameras work. Both cameras are found (serials are correct), and the network bandwidth should not be a problem (they work on Spinview and camera rate/image size have been reduced to test this). Using the launch file provided for multiple cameras, the following error shows up:

rate [Hz] in 10.0 out 0.00 drop 0% INCOMPLETE 100%

This page relates this error to a bandwith problem, although we are sure that is not the case.

Any help would be greatly appreciated.
