Make sure you have a good & reliable SD card and a proper power supply. Archives can be uncompressed with 7-Zip on Windows, Keka on OS X and 7z on Linux (apt-get install p7zip-full). RAW images can be written with Etcher (all OS).

How to boot?

Insert SD card into a slot and power the board. First boot takes around 3 minutes then it might reboot and you will need to wait another one minute to login. This delay is because system creates 128Mb emergency SWAP and expand SD card to it's full capacity. Worst case scenario boot (with DHCP) takes up to 35 seconds.

How to login?

Login as root on HDMI / serial console or via SSH and use password 1234. You will be prompted to change this password at first login. Next you will be asked to create a normal user account that is sudo enabled (beware of default QWERTY keyboard settings at this stage).

Legacy kernel images (all boards) (default branch)

  • HDMI output (if exists) supports only limited number of predefined resolutions
  • TV Out doesn't work as expected (only PAL/NTSC resolution, overscanning, no h3disp support, notes for OPi Zero)
  • 1-Wire protocol, reading out DHT11/DHT22 sensors or S/PDIF requires setting the minimum CPU frequency to 480MHz or higher
  • Hardware accelerated video decoding supports only limited number of video formats
  • 'Out of memory' (OOM) issues are possible due to a kernel bug

Mainline kernel images (all boards) (next/dev branches)

  • No Mali drivers
  • No hardware accelerated video decoding
  • schedutil CPU governor may cause clicks and pops on audio output - change(d) to ondemand to work around this issue

Board: Orange Pi Zero

  • Onboard wireless chip (XR819) has poor software support so wireless connection issues are expected
