Orange Pi 2
The H3 and Orange Pi 2 support is progressing nicely. It is possible to find a usable mainline 4.x kernel (plus some patches) and a legacy 3.4 kernel in various work-in-progress git branches. See the Manual build section for more details.
You can build things for yourself by following our Manual build howto and by choosing from the configurations available below.
Use the orangepi_2 (supported since v2016.05) build target.
The H3 boards can boot from SD, 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.
- Siarhei Siamashka's branch '20151207-embedded-lima-memtester-h3'
- Yann Dirson's fork added a few more fixes and adopted most of
- Boris Lovosevic' great initial work on Allwinner's H3 kernel
Configure this kernel using sun8i_h3_defconfig, the rest is explained in the kernel compilation guide.
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:
- 3.4-lichee-based kernel, based on work by ssvb and loboris
- Yocto support here glues together all the required parts to get this kernel to work with mainline u-boot, as well as accelerated X11/GLES support
- A newer H3 BSP variant appeared with tons of fixes which has been made available by FriendlyARM.
- A cleaned up fork has been adopted by Armbian project. On top of that Armbian maintains a bunch of 3.4.x patches for H3 devices.
The H3 SoC has decent support in mainline kernels. For cpufreq, thermal, ethernet, and HDMI, a) third party patches or b) a pre-patched distro (e.g. Armbian) is needed. The ethernet support was planned for kernel 4.13 but it was eventually reverted due to DT stability issues (will be fixed later), although the ethernet port is already accessible with U-Boot.
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Repositories with H3 patches (some already outdated):
Maxime Ripard's branch 'sunxi/for-next' (very basic H3 support, without USB)
Hans de Goede's branch 'sunxi-wip' (many work-in-progress patches, including H3 and USB support for it)
Siarhei Siamashka's branch '20151223-h3-mainline-smp-hack' (minimal set of H3 patches, with USB and SMP)
Chen-Yu Tsai's branch 'h3-emac' (working Ethernet and USB)
- Ondřej Jirman's branch for H3 based orange Pi (kernel 4.13) (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)
- Working HDMI driver (v6 patches from moinejf ported to sunxi-ng clk driver)
Use the sun8i-h3-orangepi-2.dtb device-tree binary.
Tips, Tricks, Caveats
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
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.
The Orange Pi 2 exposes a 2.54mm pitch connector.

Adding a serial port
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.
- 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.
