Eloquent branch: Errors running node

[calvertdw]

Platform: Jetson Nano 18.04 Sensor: D435

I built a colcon workspace with:

• ros2_intel_realsense (eloquent)
• librealsense (master)

with ROS 2 Eloquent installed via debs.

I put the serial number into the d435.yml

Running ros2 run realsense_node realsense_node __params:=/home/jetson/dev/realsense_ws/src/ros2_intel_realsense/realsense_examples/config/d435.yaml __ns:=/d435 yields:

what version of librealsense you are using?

This node crashes on startup around 50% of the time for me. The backtraces on each crash are all over the place, sometimes when discovering the camera, sometimes when receiving a frame. IntelRealSense/librealsense#4158 might be related, but I don't want to spend the cycles figuring out how to replace rs2::pipeline from the node

Edit: my issue was unrelated and resolved

@Jconn I am facing the same issue. How did you resolve it?
