The big.little issues in the past were caused by Samsung branded units.
The Odroid N2+ is not a Samsung design so should not suffer.
There are some posts on this forum from people that had fixes for the issues with the Samsung based Odroid XU4 boards, so it was solvable.
A user posted the N2+ is working fine with Openhab so I will be getting two of them when they are back in stock.
