ODROID-N2+ is a revision from ODROID-N2.
– Maximum CPU clock of Quad-core Cortex-A73 is increased to 2.4Ghz from 1.8Ghz.
– Maximum CPU clock of Dual-core Cortex-A53 is increased to 2.0Ghz from 1.9Ghz.
– On-board RTC backup battery holder is mounted on the board.

The main CPU is based on big.Little architecture which integrates a quad-core ARM Cortex-A73 CPU cluster and a dual core Cortex-A53 cluster with a new generation Mali-G52 GPU.

Software support

Ubuntu 20.04 LTS images are available with Kernel version 4.9.230 LTS as of today. This LTS kernel version will be officially supported until Jan, 2023.
The Mali G52 GPU Linux driver works only on the framebuffer and Wayland. We tested the latest PPSSPP emulation and it can handle x3 scaling on a 4K display nicely with well implemented VSYNC.
The fb-dev Mali driver supports OpenGL-ES 1.1, 2.0, 3.0 and 3.1 as well as OpenCL-1.2 and 2.0 at this moment. Note that you have to use the Minimal Ubuntu OS image to utilize the GPU acceleration instead of the Ubuntu Mate image.

There is a Linux Wayland driver too. Ubuntu 20.04 Gnome desktop works with fully accelerated hardware GPU on a modern Kernel 5.7.
This trial upstream OS image is available on the forum.

Android 9 Pie is ready, and you can access a source code BSP and pre-built image together. Note that GUI layer(SurfaceFlinger) resolution is limited at 2K while the video layer is true 4K.
The Android platform is based on a full 64bit system software with a Vulkan capable GPU driver.
