FreeBSD on Allwinner (sunxi) systems

Support policies

Support for all the below is done on a volunteer basis. New devices are added all the time. However, from time to time certain older devices will be dropped unless new developers volunteer to maintain them.

Supported SoCs

FreeBSD supports the following Allwinner SoCs:

Supported boards

These SoCs are found in a large number of development boards and other devices. FreeBSD has support for some of these boards, including (but not limited to) the following:

A10 Supported Boards

Note: A10 support is now in an "only as needed" basis as of 20180620. It is reasonably similar to the more-popular A20, however.

A13 Supported Boards

Note: A13 support is now in an "only as needed" basis as of 20180620. It is reasonably similar to the more-popular A20, however.

A20 Supported Boards

Note: KyleEvans has agreed to take over A20 support, thus it is no longer being considered for deprecation as of 20180620.

A31/A31S Supported Boards

Note: A31 support is being considered for deprecation as of 20180612.

What still needs to be done

The following SoC interfaces are not yet supported by FreeBSD:

The following features are not directly related to Allwinner SoCs but are often implemented on Allwinner boards:

The Allwinner boot process

Most Allwinner systems use U-Boot as the boot program. Please see this page for details.

How to Build an Image

There are several different ways to build an image.

How to setup Xorg

Install the xorg and xf86-video-scfb packages, and add the following to /etc/X11/xorg.conf:

Section "InputDevice"
    Identifier  "Keyboard1"
    Driver      "kbd"
EndSection

Section "InputDevice"
    Identifier  "Mouse1"
    Driver      "mouse"
    Option      "Protocol"      "auto"
    Option      "Device"        "/dev/sysmouse"
EndSection

Section "Monitor"
    Identifier  "Monitor"
EndSection

Section "Device"
    Identifier  "Generic FB"
    Driver      "scfb"
EndSection

Section "Screen"
    Identifier  "Screen"
    Device      "Generic FB"
    Monitor     "Monitor"
    DefaultDepth 24
    SubSection "Display"
       Depth           24
    EndSubsection
EndSection

Section "ServerLayout"
    Identifier  "layout"
    Screen      0 "Screen" 0 0
    InputDevice "Mouse1" "CorePointer"
    InputDevice "Keyboard1" "CoreKeyboard"
EndSection
