How to use Armbian images

The great Armbian documentation is available here: https://docs.armbian.com

Where to get the Armbian images

All official Armbian-based images are available at this FTP location, refer to the README.txt file inside:


You can download these images either directly from the FTP or from the torrents available in the FTP. Sometimes the torrents inside are faster way to get the images.

Console login

Default login is:

   login: root
   password: 1234

After login you'll be prompt for new password.

You could use the USB_OTG connector as serial port. Connect the board to a host computer via USB-mini cable. Wait some time for the board to boot. In the system log you should see something like:

   usb 3-2: new high-speed USB device number 5 using xhci_hcd
   usb 3-2: New USB device found, idVendor=0525, idProduct=a4a7
   usb 3-2: New USB device strings: Mfr=1, Product=2, SerialNumber=0
   usb 3-2: Product: Gadget Serial v2.4
   usb 3-2: Manufacturer: Linux 4.19.5-sunxi with musb-hdrc
   cdc_acm 3-2:2.0: ttyACM0: USB ACM device

Then use picocom, minicom, etc to login:

   picocom -b 115200 /dev/ttyACM0
   18.04.1 LTS olinuxino ttyGS0
   olinuxino login:

Selecting video output

On most boards you can select between HDMI and LCD output

  • A20-OLinuXino
    • HDMI
    • LCD
  • A33-OLinuXino
    • LCD

HDMI output if always with highest priority. That means you you plug HDMI cable, the output always will be on the monitor, regardless of other settings.

If HDMI is not present, then LCD output will be used. By default the image tries to use auto-detect method for the LCD. This will only work on newer panels and boards. You can manually override this in the u-boot console as follows.

  • Stop in the u-boot
   Autoboot in 1 seconds, press <Space> to stop
  • List all supported LCD panels:
   olinuxino monitor list
   Supported video outputs:
   LCD-OLinuXino                  - Video outout to the LCD connector with AUTO detect function
   LCD-OLinuXino-4.3TS            - Video output to LCD-OLinuXino-4.3TS
   LCD-OLinuXino-7                - Video output to LCD-OLinuXino-7
   LCD-OLinuXino-5                - Video output to LCD-OLinuXino-5
   LCD-OLinuXino-10               - Video output to LCD-OLinuXino-10
  • Set configuration, for example LCD-OLinuXino-7
   olinuxino monitor set LCD-OLinuXino-7
  • You can make changes permanent with:
  • Reboot the board and you're ready:

Selecting bootlog console

You can select the bootlog to be displayed on HDMI/LCD or on the debug serial port. This is done via armbianEnv.txt file.

Open the file:

   nano /boot/armbianEnv.txt

For bootlog on the serial port use:


For bootlog on HDMI/LCD console:


Save the file and reboot the board.

Updating image

You can update the the board using apt.

Building u-boot

Get the latest sources:

 git clone https://github.com/OLIMEX/u-boot.git
 cd u-boot

Build it:

 make A20-OLinuXino_defconfig
 make CROSS_COMPILE=arm-linux-gnueabihf-

Updating via USB

You can write the new u-boot to MMC, eMMC, SPI Flash or NAND (not fully supported) using DFU protocol.

Boot the board and stop at u-boot console. Connect USB-mini cable to a host PC.

Update SPI flash

Check the available partitions with:

   => mtd
   device nor0 <flash.0>, # parts = 4
    #: name		size		offset		mask_flags
    0: SPI.u-boot          0x00200000	0x00000000	0
    1: SPI.u-boot-env      0x00020000	0x00200000	0
    2: SPI.u-boot-env.backup0x00020000	0x00220000	0
    3: SPI.user            0x00dc0000	0x00240000	0
   active partition: nor0,0 - (SPI.u-boot) 0x00200000 @ 0x00000000
   mtdids  : nand0=nand.0,nor0=nor.0
   mtdparts: mtdparts=nand.0:4m(NAND.SPL),4m(NAND.SPL.backup),4m(NAND.u-boot),4m(NAND.u-boot.backup),4m(NAND.u-boot-env),4m(NAND.u-boot-env.backup),4m(NAND.dtb),16m(NAND.kernel),-(NAND.rootfs);nor.0:2m(SPI.u-boot),128k(SPI.u-boot-env),128k(SPI.u-boot-env.backup),-(SPI.user)

Activate DFU protocol with:

   => dfu 0 sf "0:0:25000000:0"
   interface: sf, devstr: 0:0:25000000:0

Next, on the host PC run:

   dfu-util -l
   dfu-util 0.9

   Found DFU: [15ba:0041] ver=0215, devnum=6, cfg=1, intf=0, path="3-2", alt=2, name="SPI.u-boot-env.backup", serial="ffffffff"

   Found DFU: [15ba:0041] ver=0215, devnum=6, cfg=1, intf=0, path="3-2", alt=0, name="SPI.u-boot", serial="ffffffff"

Update u-boot binary with:

   dfu-util -D spl/u-boot-spl.bin -a SPI.u-boot

Update SD/eMMC card

Stop loading in the u-boot. To check available MMC devices run:

   mmc list

If the board is booted from SD card and you also have eMMC, the output will be:

   mmc@01c0f000: 0 (SD)
   mmc@01c11000: 1 (eMMC)

Connect USB-mini cable enter:

   ums 0 mmc 0


   ums 0 mmc 1

New mass storage device will show-up on the host computer. To write u-boot use:

   sudo dd if=u-boot-sunxi-with-spl.bin of=/dev/sdX seek=16 conv=sync

where /dev/sdX should be replaced with the new device, /dev/sdb, /dev/sdc, etc.

Building image

Make sure to take a look at the official Armbian documentation here: https://docs.armbian.com

  • Clone repository
 git clone --branch olimex https://github.com/olimex/build
  • Run build script
   cd build

Building requires root access. System preparation can take long, depending on system, internet connection, etc. After everything is ready a prompt will appear:

   Select what to build:
       -> U-boot and kernel packages 
       -> Full OS image for flashing

The first option will build only u-boot and kernel packages. This is suitable for updating image. The second option will make ready to use image with u-boot, kernel and rootfs.

   Select the kernel configuration:
       -> Do not change the kernel configuration
       -> Show a kernel configuration menu before compilation

Here you can modify kernel configuration, before build. After that target must be selected. Olimex's images are not officially supported by Armbian team, so you must select Show CSC/WIP/EOS option.

   Select the target board. Displaying:
       -  (CSC)  -  Community Supported Configuration
       -  (WIP)  -  Work In Progress
       -  (ESO)  -  End Of Support

Here select either:

   olinuxino-a20  - Common configuration file for All A20-OLinuXino boards


   olinuxino-a33  - A33 quad core 1Gb Soc

Next kernel variant must be selected. Here select next branch:

   Select the target kernel branch
   Exact kernel versions depend on selected board
       -> default  Vendor provided / legacy (3.4.x - 4.4.x)
       -> next     Mainline (@kernel.org)   (4.x)
       -> dev      Development version      (4.x)

Next select distribution:

   Select the target OS release
       -> jessie   Debian 8 Jessie / unsupported
       -> stretch  Debian 9 Stretch
       -> xenial   Ubuntu Xenial 16.04 LTS
       -> bionic   Ununtu Bionic 18.04 LTS

Finally select building desktop environment or not:

   Select the target image type
       -> Image with console interface (server)
       -> Image with desktop environment

After some time the image / packages will be available in the output directory. For example:

   tree output
   |-- debs
   |   |-- armbian-config_5.65_all.deb
   |   |-- armbian-firmware_5.65_all.deb
   |   |-- armbian-firmware-full_5.65_all.deb
   |   |-- armbian-tools-bionic_5.65_armhf.deb
   |   |-- bionic
   |   |   |-- armbian-bionic-desktop_5.65_all.deb
   |   |   |-- linux-bionic-root-next-olinuxino-a20_5.65_armhf.deb
   |   |-- linux-dtb-next-sunxi_5.65_armhf.deb
   |   |-- linux-headers-next-sunxi_5.65_armhf.deb
   |   |-- linux-image-next-sunxi_5.65_armhf.deb
   |   |-- linux-source-next-sunxi_5.65_all.deb
   |   |-- linux-u-boot-next-olinuxino-a20_5.65_armhf.deb
   |   |-- Armbian_5.65_Olinuxino-a20_Ubuntu_bionic_next_4.19.5_desktop.img
  • Flashing image

Put sdcard in the host PC. New device should appear, e.g. /dev/sdc. Flash the image using the following command:

 # dd if=/path/to/Armbian_5.65_Olinuxino-a20_Ubuntu_bionic_next_4.19.5_desktop.img.img of=/dev/sdx bs=10M

Replace /dev/sdx with your device. You must use /dev/sdx, not /dev/sdx1!
