   NetBSD supports many boards based on Allwinner SoCs. Starting with NetBSD 8.0, FDT is used to configure devices. As a result, a large number of boards and configurations can be supported with a single kernel.

 # Installation  # Installation
   
 ## A10 / A20 / A31 based boards  - Download or build **armv7.img** (32-bit) or **arm64.img** (64-bit) from NetBSD -current
   - Write the image to disk: **dd if=armv7.img of=/dev/rld0d bs=1m conv=sync**
   - Install a board-specific U-Boot (2018.05 or later) from pkgsrc to the SD card
     (the `u-boot-sunxi-with-spl.bin`-s are provided by `sysutils/u-boot-<boardname>` packages):
     **dd if=/usr/pkg/share/u-boot/&lt;boardname&gt;/u-boot-sunxi-with-spl.bin of=/dev/rld0d bs=1k seek=8 conv=sync**
   
 * Start with an ARMv7 image from *evbarm-earmv7hf/binary/gzimg/* such as *beagleboard.img*  If your SoC has a SATA controller and you would like to install on
 * Download a U-Boot build for your board  an hard disk and use a SD card only for u-boot please give a look
   * A10/A20: Download from the linux-sunxi web site <http://dl.linux-sunxi.org/nightly/u-boot-sunxi/u-boot-sunxi/u-boot-sunxi-latest/>  to
   * A31: The standard u-boot-sunxi tree doesn't support A31 yet. Until sun6i support is merged, a build is available at <http://dis.invisible.ca/allwinner/a31/  [[NetBSD/evbarm install via sysinst(8) on a SATA hard disk, USB stick or (u)SD card|ports/evbarm/install_using_sysinst]].

 [[!template  id=programlisting text="""  
 # dd if=u-boot-sunxi-with-spl.bin of=beagleboard.img bs=1k seek=8 conv=notrunc  
 """]]  
 * Write the image to an SD card.  
 * Copy the kernel (netbsd.ub) for your board to the root of the MS-DOS partition.  
 * Create or edit uEnv.txt on the MS-DOS partition:

 # Big (endian) fun  On some television models, the borders of the screen may be cut off. If your television doesn't have an option to disable overscan, you can enable overscan compensation by entering the following commands at the U-Boot prompt:
   
 You can run this boards with a little endian (this is the default and implied by above install instructions)      setenv video-mode sunxi:1280x720-24,overscan_x=32,overscan_y=20
 or with a big endian kernel and userland. However, kernel and userland endianness needs to match.      saveenv
       reset
   
 To build a big endian release (or sets) use   ## Pinebook function keys
 [[!template  id=programlisting text="""  
 ./build.sh -m evbearmv7hf-eb   
 """]]  
 where -eb means endianness big, hf is hardware floating point support, and earm is the modern "extended" ABI for ARM CPUs, and finally v7 is version 7 of the supported instruction set.  
   
 # FEX scripts  The sleep (Fn+Esc), home (Fn+F1), volume down (Fn+F3), volume up (Fn+F4), and mute (Fn+F5) keys on the keyboard are mapped to uhid(4) devices.
   
 Board configuration scripts can be found here: <https://github.com/linux-sunxi/sunxi-boards/blob/master/sys_config>. You can compile them with the "fex2bin" tool found here: <https://github.com/linux-sunxi/sunxi-tools>.  Create the following config file:
   
   [[!template  id=filecontent name="/etc/usbhidaction.conf" text="""
   Consumer:Consumer_Control.Consumer:Volume_Up                    1
           mixerctl -n -w outputs.master++

 To use, copy the compiled FEX to your MS-DOS partition, load it with U-Boot, and then tell the kernel where to find it with the "sysconfig=" boot option. For example, uEnv.txt on a Cubieboard2 might look like this:  Then start two copies of usbhidaction:
   
 [[!template  id=programlisting text="""  [[!template  id=programlisting text="""
 bootargs=root=ld0a sysconfig=0x43000000  # /usr/bin/usbhidaction -c /etc/usbhidaction.conf -f /dev/uhid0 -i -p /var/run/usbhidaction-uhid0.pid 
 uenvcmd=mmc dev 0; mmc rescan; fatload mmc 0:1 43000000 cubieboard2.bin; fatload mmc 0:1 82000000 netbsd.ub; bootm 82000000  # /usr/bin/usbhidaction -c /etc/usbhidaction.conf -f /dev/uhid1 -i -p /var/run/usbhidaction-uhid1.pid 
 """]]  """]]
   
 Some pre-compiled .bin files can be found here: <http://ftp.netbsd.org/pub/NetBSD/misc/jmcneill/allwinner/fex/>  ## Pinebook keyboard
   
 # Framebuffer console  The new 11" 1080p model has a slightly different keyboard layout to the 14".
   Using wscons it works perfectly, but using X the \ key next to left shift will display > when pressed.
   To solve this, you need to change the keyboard layout to altgr-intl. This can be done system wide by creating the file:
   
 To use HDMI for the console device, add *console=fb* to bootargs in uEnv.txt.  [[!template  id=filecontent name="/etc/X11/xorg.conf.d/00-system-keyboard.conf" text="""
   Section "InputDevice"
           Identifier "Pinebook 1080p keyboard"
           Driver     "kbd"
           Option     "XkbLayout"  "us"
           Option     "XkbVariant" "altgr-intl"
   EndSection
   """]]
   
 If the connected display does not let you disable overscan, you can add a margin to the framebuffer by with the *fb.margin* bootargs option. For example, to set a 25-pixel margin around the screen, add *fb.margin=25* to uEnv.txt  ## Pinebook screen
   
 # HDMI audio  X11 currently cannot work out the size of the screen, resulting in a very small DPI on a very small screen.
   This file configures X to use an 11.6" screen, which results in very readable a DPI of 190.
   
 The default audio device is the analog audio codec. To change the default device, use the *audiocfg* command:  [[!template  id=filecontent name="/etc/X11/xorg.conf.d/01-pinebook-11-screen.conf" text="""
   Section "Monitor"
           Identifier      "Pinebook 11.6 inch monitor"

 # Board specific notes  
   
 ## Merrii Hummingbird A31  
   
 There doesn't appear to be a meaningful way to generate a MAC address on these boards. U-Boot from the A31 SDK and from the u-boot-sunxi tree both lack GMAC support, and the Security ID registers (at 0x01c23800) appear to be empty.  # Links
   
 To overcome this, you can specify your own MAC address in *uEnv.txt*:  - [[NetBSD/evbarm install via sysinst(8) on a SATA hard disk, USB stick or (u)SD card|ports/evbarm/install_using_sysinst]]
