How to use Armbian images

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

Console login

Default login is:

   login: root
   password: 1234

After login you'll be prompt for new password.

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:
   saveenv
  • Reboot the board and you're ready:
   reset

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
   
   defaults:
   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

Update u-boot binary with:

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

Building image

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

  • Clone repository
 # git clone https://github.com/armbian/build.git

Soon (probably) there will be olimex fork with some customizations.

  • Run builder
 # cd build
 # ./compile

Building requires root access. System preparation can take long, depending on system, etc. After that you should see something like that:

Armbian-1.png

Select Full OS Image for flashing. This will create output image for direct flashing on SD-card.

Armbian-2.png

Select Do not change the kernel configuration. All needed configuration should be selected automatically. If you want some kernel modifications, select the other option.

Armbian-3.png

Go to <Show CSC/WIP/ESO>. Currently A20-SOM204 is not officially supported by Armbian team. Instead the board is supported by Olimex team, which is under CSC section. So select that menu and confirm the action.

Armbian-4.png Armbian-5.png

Select olimex-som204-a20.

Armbian-6.png

Select desired distribution. We recommend jessie for server build, and xenial for image with desktop environment.

Armbian-7.png

Select if you want server or desktop.

After build the images and other packages will be in the output folder:

  • 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=Armbian_5.41_Olimex-som204-a20_Debian_jessie_dev_4.15.0.img of=/dev/sdx bs=10M

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