The N2 GPIO interface is similar to C2 and fully supports a 3.3Volt interface while N1 could only support 2.8Volt IO. This is beneficial for using various peripherals without complicated level shifters. Amlogic S922X Processor (12nm fab) Quad-core Cortex-A73(up to 2.4Ghz) and Dual-core Cortex-A53 (up to 2Ghz) 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. The Mali G52 GPU Linux driver works only on the framebuffer. We tested the latest PPSSPP emulation and it can handle x3 scaling on a 4K display nicely with well implemented VSYNC.

Extra Storage issue fixed. 16gb eMMC is not enough after a while. I don't have bigger emmc and such material is very difficult and very expensive to get in my country. Attributes: { Content type: AUDIO_CONTENT_TYPE_UNKNOWN Usage: AUDIO_USAGE_UNKNOWN Source: AUDIO_SOURCE_DEFAULT Flags: 0x4 Tags: }

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. An Ubuntu 18.04 LTS image is available with Kernel version 4.9.152 LTS at this moment. This kernel version will be officially supported until Jan, 2023. On average, the ODROID-N2 is 30–35% faster than Firefly RK3399, my default board. Also it has way better memory throughput, up to 40% faster. I also benchmarked other RK3399 boards in the past and they all score close to the Firefly numbers. The CPU multi-core performance is around 20% faster and the 4GByte DDR4 RAM is 35% faster than the N1. The N2’s DDR4 RAM is running at 1320Mhz while N1’s DDR3 was running at 800Mhz.W KernelCpuProcStringReader: File not found.

To get started, we suggest the ODROID N2+, the board that powers our Home Assistant Blue, or the ODROID M1.
