Segmentation Fault D430 - Raspberry Pi

Morning all,

Ive been struggling to get the D430 working with a Raspberry Pi 3B+ (Raspian Lite) Specifically using the python wrapper.

Ive build the SDK using the following instructions https://github.com/IntelRealSense/librealsense/blob/b99457e002dd4c0501226a52c5bc0682992a0576/doc/installation_raspbian.md

Ive been running the following python script (with a few changes) https://github.com/IntelRealSense/librealsense/blob/master/wrappers/python/examples/opencv_viewer_example.py which opens up the OpenCV window for a few seconds, freezes then closes. The error i see is "Segmentation Fault"

I've ran dmesg which returns the following:

Any ideas what this could be?

There was a similar case in April 2019 where a RealSense user who was using Rasbian was finding that it was getting stuck.

Have you set up a swap file please, as suggested by the instructions? The importance of a swap file is also referenced in the discussion in the link below.

Cheers MartyG!

I think i got a bit excited to set everything up and I missed one important step, upgrading the firmware on the camera! Just sat back down at my desk and everything now working as expected after the upgrade...
