Orange Pi 2 is H3 based development board produced by Xunlong. The concept is based on the original Orange Pi. Both, Orange Pi 2 and its smaller cousin Orange Pi Mini 2 (similar to Orange Pi Mini) were released in March 2015. The board is based on a quad-core H3 CPU, and offers a TF card slot, onboard Ethernet (10/100M Ethernet RJ45) and WiFi (802.11 b/g/n), 40 pin GPIO and 4 x USB type A connectors, but does not come with the SATA port like the A20 based original Orange Pi did.

Sunxi support

Current status

The H3 SoC support has matured since its introduction in kernel 4.2. Most of the board functionality for boards such as Orange Pi 2 are available with current mainline kernels. Some features (hw accelerated crypto, hw spinlocks, and thermal) 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 (supported since v2016.05) build target. The U-Boot repository and toolchain is described in the Mainline U-Boot howto.

The H3 boards can boot from SD cards, eMMC, NAND or SPI 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. The .fex file can be found here for now orangepi2.fex. This was extracted from the android sdcard image.

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 mainline kernel has good support for the H3 SoC. Please refer to the status matrix for a more detailed list of the development process, links to patches and links to kernel fork repositories. Minor drivers that are currently work-in-progress may require a) third party patches (see also arm-linux mailing list) or b) a pre-patched distro (e.g. Armbian).

Repositories with H3 patches:


Use the sun8i-h3-orangepi-2.dtb 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 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 2's LED activity is good. The red power LED (D7) can be turned off.

Expansion Ports

The Orange Pi 2 exposes a 2.54mm pitch connector.

Adding a serial port

UART pads

Locating the UART

The UART pins are located on J3 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.

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 smaller cousin Orange Pi Mini 2 (similar to Orange Pi Mini) were also released in March 2015.

There are several websites about Orange Pi 2 and claiming to support it. It has to be clarified, what is "official" and who is behind this sites.

Currently only an android image for an sdcard is provided via OrangePi's Website.
