Orange Pi Prime v1.0
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 are available with current mainline kernels. Some features (hw accelerated crypto, hw spinlocks, and thermal) are still being worked on and the status of some features (video engine) is still unknown due to the lack of testing. For a more comprehensive list of supported features, see the status matrix for mainline kernels.
See the Manual build section for more details.
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).
You can build things for yourself by following our Manual build howto and by choosing from the configurations available below.
Use the orangepi_prime_defconfig (supported since v2017.07) build target.
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/)

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:
x - no protection, ESD - Electrostatic Discharge, OC - Over-current
|1||USB micro (power)||ESD||x||Uses TVS diode, power supply bypass|
|5||Dual USB1||ESD||OC (1.1A)||Over-current protection provided by SY6280, 1.1A shared for both ports, power supply bypass.|
|6||USB2||ESD||OC (1.1A)||Over-current protection provided by SY6280, power supply bypass.|
|6||Micro USB||ESD||OC (680mA)||Over-current protection provided by SY6280, power supply bypass.|
|8||Ethernet||x||N/A||Over-current protection is not applicable|
|11||Audio jack||x||N/A||Output current is internally limited by SoC|
Adding a serial port
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:
- 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.
