Hello @ChrisHughes ,
The kernel patches are meant for Ubuntu distributions with LTS kernels.
The board you're using runs a different dedicated 4.4.76-aero-1.2 kernel as you mention.

Please also see a related #1320 with instructions on how to integrate D400/Librealsense2 with Aero board

[ev-mp]

Hello @ChrisHughes , please update whether you need a further assistance with this.

[ChrisHughes]

Thanks, the patch on #1320 worked well and solved the issue for me. Would be helpful to have it included officially and in the build docs.
