Hello,
We purchased a Dingo-D with a Jetson Orin. The Orin was installed with Jetpack 6.1 and ROS2 Humble under Ubuntu 22.04. For our internal R&D purposes, we attached a deserializer board to the Orin to control GMSL cameras and upgraded to Jetpack 6.2. So far so good.
When we connected to the robot, we noticed the robot PC was running ROS2 Jazzy under Ubuntu 24.04. The problem is that (inter-distribution) communication between Humble and Jazzy is (reportedly) not supported. During first experiments, we observed the same out-of-memory (OOM) symptoms as described in Running a subscriber on Humble with publishing from Jazzy / Rolling uses up all memory · Issue #797 · ros2/rmw_fastrtps · GitHub. Using rmw_cyclone_cpp as RMW seems to solve the OOM issues, but several topics are not interpreted (correctly).
On the clearpath page it is stated in Nvidia Jetson Installation | Clearpath Robotics Documentation that Humble is no longer actively maintained, on the NVidia page it is mentioned that ROS2 Jazzy cannot be used on Jetsons at this time.
Do you have suggestions on how to proceed ?
