Sunxi support

Current status

The H5 SoC support has matured since its introduction in kernel 4.12. Most of the board functionality for boards such as Orange Pi Prime, including 3D graphics, hardware accelerated video and crypto, and DVFS are available with current mainline kernels. Only a very few minor features are still being worked on. For a more comprehensive list of supported features, see the status matrix for mainline kernels.

See the Manual build section for more details.

BSP

There are some somewhat abandoned 3.10 BSP code drops available in 'OrangePiLibra' and FriendlyELEC's github repos. Check the orangepi-xunlong and OrangePiLibra repositories in case of interest.

It seems no device settings are contained and the BSP is broken anyway at least with regard to voltage regulation (that's also the reason vendor OS images seem to be limited to 1008 MHz since at this cpufreq those Orange Pi do not immediately crash with BSP kernel).

Manual build

You can build things for yourself by following our Manual build howto and by choosing from the configurations available below.

U-Boot

Mainline U-Boot

Use the orangepi_prime_defconfig (supported since v2017.07) build target.

Linux Kernel

Sunxi/Legacy Kernel

Mainline kernel

The H5 SoC has support in the mainline kernels.

The development process, links to patches and links to kernel fork repositories are listed on the Linux mainlining effort page. Patches can also be found from the arm-linux mailing list.

Repositories with H5 patches:

Ondřej Jirman's branch for H5 based orange Pi (kernel 4.19) (work-in-progress DVFS)
- Thermal regulation (if CPU heats above certain temperature, it will try to cool itself down by reducing CPU frequency)
- HDMI audio support (from Jernej Skrabec)
- Configure on-board micro-switches to perform system power off function
- Wireguard (https://www.wireguard.com/)

Use the sun50i-h5-orangepi-prime.dtb device-tree binary.

Expansion Port

The Orange Pi Prime has a Raspberry Pi model B+ compatible 40-pin, 0.1" connector with several low-speed interfaces.

ESD & over-current protections

Based on the schematic Rev 1.0 (September 29, 2016) the board incorporates the following protections:

Protections x - no protection, ESD - Electrostatic Discharge, OC - Over-current				Comments
1	Power jack	ESD (1)	x	Uses TVS diode, power supply bypass.
2	Micro SD	x	x
4	Camera	x	x
5	Dual USB1	ESD (1)	OC (1.1A)	Over-current protection provided by SY6280, 1.1A shared for both ports, power supply bypass.
6	USB2	ESD (1)	OC (1.1A)	Over-current protection provided by SY6280, power supply bypass.
6	Micro USB	ESD (1)	OC (680mA)	Over-current protection provided by SY6280, power supply bypass.
7	HDMI	ESD (1)	x
8	Ethernet	x	N/A	Over-current protection is not applicable
9	GPIO	x	x
10	Debug UART	x	?
11	Audio jack	x	N/A	Output current is internally limited by SoC

Notes:

On online OrangePi Prime pictures as well as on personal pictures it can be noticed that manufacturer has removed all ESD protection components on all USB ports and on I2C bus of HDMI port.

Adding a serial port

UART pins

The board exposes Debug serial 3-pin port which is located between Reset and Power switches (see picture on the right). The 3-pin port layout is the following:

GND
CPU RX
CPU TX

This connector is connected to UART0 using pins PA4 (TX) and PA5 (RX). Please refer to our UART howto for further details.
