Sunxi support

Current status

The H3 chipset support for Orange Pi Mini 2 has been included in mainline kernels since 4.2. Most of the board functionality works out of the box, but support for many features has been added rather recently, which means that a fairly recent kernel version is required. Some features (hw accelerated crypto, graphics/video features, thermal, and DVFS) are still being worked on. For a more comprehensive list of supported features, see the status matrix for mainline kernels. In addition, legacy 3.4 kernels are available in various work-in-progress git branches.

See the Manual build section for more details.


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_2 (as a workaround until Orange Pi Mini 2 defconfig is available) build target. The U-Boot repository and toolchain is described in the Mainline U-Boot howto.

The H3 boards can boot from SD, eMMC, NAND or NOR flash (if available), and via FEL using the OTG USB port. In U-Boot, loading the kernel is also supported from USB or ethernet (netboot). HDMI support in U-Boot is still WIP.

Linux Kernel

Sunxi/Legacy Kernel

The 3.4 kernel from the official Allwinner's git repository does not support H3 yet. But it is possible to use one of the kernel forks, based on the lichee H3 SDK tarball:

Configure this kernel using sun8i_h3_defconfig, the rest is explained in the kernel compilation guide.

Use the .fex file for generating script.bin.


When booting the legacy 3.4 kernel with the mainline U-Boot, add the following line to boot.cmd:

  setenv machid 1029
  setenv bootm_boot_mode sec

Some other legacy kernel repositories:

Mainline kernel

The H3 SoC is supported by the mainline kernels. For cpufreq, thermal, and HDMI, a) third party patches or b) a pre-patched distro (e.g. Armbian) is needed. Although the ethernet port is accessible in U-Boot, the kernel support has stabilized only recently in kernel 4.15.

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 H3 patches:

  • OndÅ™ej Jirman's branch for H3 based orange Pi (kernel 4.14) (work-in-progress DVFS)
    • CPU frequency and voltage scaling (cpufreq)
    • Thermal regulation (if CPU heats above certain temperature, it will try to cool itself down by reducing CPU frequency)
    • DMI output support (patches from jernejsk and icenowy, with DTS changes for H5 by me)
    • Configure on-board micro-switches to perform system power off function
    • Wireguard (https://www.wireguard.com/)


Use the sun8i-h3-orangepi-2.dtb (until a dedicated dtb is available) device-tree binary.

Tips, Tricks, Caveats

FEL mode

The button marked SW3, located between the HDMI and TTL UART, triggers FEL mode when pressed during boot.

To verify you have successfully entered FEL mode, check the output of fel version. For the Orange Pi Mini 2, it should look like:

AWUSBFEX soc=00001680(unknown) 00000001 ver=0001 44 08 scratchpad=00007e00 00000000 00000000

LEDs

For those with a transparent case (or no case at all) the Orange Pi Mini 2's LED activity is good. The red power LED (D7) can be turned off.

Adding a serial port

UART pads

Locating the UART

The UART pins are located between DC input and Uboot Button(SW3) of the board. They are marked as TX, RX and GND on the PCB. Just attach some leads according to our UART Howto. Do not connect the red wire (VCC or 3.3V/5V), as that might damage your board.

Variants

  • The original Orange Pi was released in November 2014. The orange pi features a standard TF card slot and a 26 pin GPIO connector (similar to the Raspberry Pi A/B).
  • The Orange Pi Mini was released in November 2014, too. It has two TF card slots and only has 2 USB Host.
  • The Orange Pi Plus was presented in February 2015. It's a new board, and it uses the AllWinner H3 SoC. It Has a 8GB EMMC Flash, Onboard Network(10/100/1000M Ethernet RJ45), Onboard WIFI(Realtek RTL8189ETV, IEEE 802.11 b/g/n), Video Outputs(Supports HDMI CEC, Supports HDMI 3D function, Integrated CVBS, Supports simultaneous output of HDMI and CVBS) and a 40 pin GPIO header (that mimics the Raspberry Pi A+/B+ models).
  • Now Orange Pi 2 and Orange Pi Mini 2 are released in March 2015. They are both based on a quad-core H3 CPU, and offer TF card slot, onboard Network(10/100M Ethernet RJ45), 40 pin GPIO and 4 USB type A connectors. They are difference in onboard wifi. Orange Pi 2 has wifi module, while Orange Pi Mini 2 does not have. However, the two kinds of devices do not have SATA any more.
