Can you please try to use gdb to debug your application?
stop the background service : systemctl stop voxl-tflite-server run the server in foreground : gdb /usr/bin/voxl-tflite-server, press r + enter wait for the server to crash, and type bt + enter to get a back trace of the thread that crashed.We will double check regarding the param in voxl-configure-tflite-server.
