I am trying to make Intel NCS2 works on my Odroid XU3 board (https://hardkernel.com/shop/odroid-xu3/) with Ubuntu 16.04.
I followed the "Install OpenVINO™ toolkit for Raspbian* OS" and see how far I can go.
It was ok until the step "Build and Run Object Detection Sample".
I understand Intel NCS2 may not support Odroid XU3 at all, however, I decide to give it a go.
I am sharing some warning and error I got, hopefully someone can provide some advice to work around these issues.
Here are some details
