Allwinner H3 (sun8iw7p1) SoC features a Quad-Core Cortex-A7 ARM CPU, and a Mali400 MP2 GPU from ARM. The Allwinner H3 is a highly cost-efficient quad-core OTT box processor, primarily marketed as being for "home entertainment" systems.

It has a nearly-compatible variant known now, H2+.

It's rated to run at 1.296GHz, anything higher is overclocking (and usually overvolting). If you run it without heatsink, fan and proper dvfs settings, you risk overheating.

Variants

H2+ is a variant of H3, targeted at low-end OTT boxes, which lacks Gigabit MAC and 4K HDMI output support.

H3 images are proven to run on H2+.

According to the source code of BSP[1], variants differ by the last byte of the first word of SID. 0x42 and 0x83 indicates H2+, 0x00 and 0x81 indicates H3, and 0x58 indicates H3D (a still unknown variant).

U-Boot

Allwinner

Mainline U-Boot

Starting with version 2016.01, the official mainline U-Boot has supported the H3 SoC and various boards with it. This is the recommended way of booting boards when not using BSP kernels.

U-Boot defconfigs still missing for these H3 boards:

* Orange Pi Mini 2 (as a workaround, please use orangepi_2 defconfig)
* Orange Pi Plus 2 (as a workaround, please use orangepi_plus defconfig)
* pcDuino4 Nano (as a workaround, please use orangepi_one defconfig)

Kernel code

Allwinner

Sunxi Community

The mainline Linux kernel supports the H3 SoC quite well. For a more comprehensive list of supported features, see the status matrix for mainline kernels.

Device tree configs still missing for these H3 boards:

* Orange Pi Mini 2 (as a workaround, please use sun8i-h3-orangepi-2.dtb)
* Orange Pi Plus 2 (as a workaround, please use sun8i-h3-orangepi-plus.dtb)
* pcDuino4 Nano (as a workaround, please use sun8i-h3-orangepi-one.dtb)
