  • serial console gadget on the OTG port is available after the system boots up. Please make sure that board is properly powered (i.e. with microUSB Y cable or via GPIO pins) because a standard PC USB port will not provide enough current to the board

Known issues

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

  • ‘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 module (XR819) has poor software support so wireless connection issues are expected
  • Onboard wireless module (XR819) is not supported on mainline releases
  • board revision 1.4 report false high CPU temperatures.

Preparation
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).
Boot
Insert SD card into a slot and power the board. (First) boot (with DHCP) takes up to 35 seconds with a class 10 SD Card and cheapest board.
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).
