Error during ''live processing'' with DAVIS 346

[C4sp1]

Hi! I am currently trying to run the pipeline in live mode on ROS-Melodic, Ubuntu 18.04, using DAVIS 346 sensor. I tried to run it with the ''flyingroom rosbag'' and the pipeline started without any errors. When I run it in live mode, SVO node always crushes right away.

I did the following steps:

• put the calibration file in the /home/c4sp1/catkin_ws/src/rpg_dvs_evo_open/dvs_tracking/parameters/calib folder
• run roscore on one terminal
• run davis driver on a second terminal
• run roslaunch dvs_tracking live.launch auto_trigger:=false camera_name:=DAVIS-00000336 events_topic:=/dvs/events

where DAVIS-00000336 is the same calibration file that is saved in the .ros/camera_info folder.

Every time I run roslaunch I get the following error:

[svo-1] process has died [pid 9955, exit code -11, cmd /home/c4sp1/catkin_ws/devel/lib/svo_ros/svo_node events:=/dvs/events remote_key:=/evo/remote_key __name:=svo __log:=/home/c4sp1/.ros/log/a996bfae-f69f-11eb-b50f-b07b25408b14/svo-1.log].
log file: /home/c4sp1/.ros/log/a996bfae-f69f-11eb-b50f-b07b25408b14/svo-1*.log

I also get this warning nevertheless the distorsion model is specified in the calibration file.

[ WARN] [1628256826.590702738]: Camera calibration file did not specify distortion model, assuming plumb bob

Any ideas on what might be the issue?

Thanks

I attach all the terminal output which generate the error
