The CI20 ships with Debian7 installed, but a number of other distributions have been built and run on CI20 already. Those distributions are undergoing preparation for their images to be uploaded to the file store, and the links here will be updated in due course.

As the images are generated, the procedure used to build and burn the images will be documented by articles in the CI20 Rootfs Guides category.

How to burn images

For instructions on how to use the below images please see the Dev Zone.


The Debian 8 NAND flashing image, as used for the production NAND image, is available to download from the following links.

To burn the CI20 on-board NAND back to the factory default image download the following SDcard image and follow the instructions on Flashing the NAND Image.

Debian 8 2015-09-09 Beta

The Debian 8 NAND image is available here The rootfs tarball used to create this image is available here

This is a major release. Kernel upgrade from 3.0.8 to 3.18. Debian upgrade from 7 to 8.
Please read the release notes carefully.

The associated md5sums are

Legacy Images

Old images can be found here.


Android KitKat 4.4.2 image is available for download.

The image is 1.1G. You'll need an SD card to flash it on the CI20 - Check Flashing the NAND Image.

The latest image is: 2015-06-04-v0.6 (download here).

Details on how to make the image are available here.


  • USB mount fixed
  • Boot-up time decreased (3 minutes - first boot, 2 minutes - each other boot)
  • Camera - capturing photos and recording videos
  • Memory leak in Ethernet settings application fixed
  • Wake up from suspend mode fixed
  • Fixed Breakpoint handling with java debugger


  • Videos work. Check out in the browser!
  • Takes quite a bit of time for first boot after you flash android. So don't worry :). The recent change in the way UBIFS partitions are mounted helps.
  • Instructional video here:-

For further detail check out the Android on the MIPS CI20 page.


A Gentoo Linux SDCard image is available on the Gentoo mirrors:


All the instructions are in the README file.

Please find the Gentoo mirrors list here:


Yocto Sato is running on CI20 - you can download the image here

The image is around 200Mbyte. You'll need an SD card to flash it on the CI20. Check Flashing the NAND Image.

The image was made using the steps documented on How to make a yocto rootfs for MIPS CI20.

A few details

  • Serial/Getty is on ttyS0. If you find a fix for getty on ttyS4, please email the list.
  • Display Resolution compiled in kernel is 1024x768 for greater compatibility with monitors.
  • The image uses kernel 3.0.8


Angstrom with a XFCE4 UI is running on the CI20 - you can download the image here

The image is 1Gbyte. You'll need an SD card to flash it on the CI20. Check Flashing the NAND Image.

The image was made using the steps documented on How to make an Angstrom rootfs for MIPS CI20.


Arch is running on CI20, and an image is in progress...


For instructions how to make buildroot, see How to make a buildroot rootfs for MIPS CI20.

This is a small (~70Mb) buildroot image. It boots directly from the sd card and doesn't flash the NAND.

Just dd the image on an sd card. (dd if=image.img of=/dev/sdX). Or windows32diskimager.

It has a minimal X environment too :).

Suitable for checking your board and running memtest.

  • Username ci20
  • Password ci20
  • Root password ci20
  • For some reason, have to login via user ci20 and then su to root if logging in via monitor/tv.

Specific notes fir 2015_03_03: This image has ddr timings tweaked. Purpose. Requesting people to run memtest using this.


OpenWRT support is a work in progress. Check the following links:

Check for detailed status.


OpenELEC (short for "Open Embedded Linux Entertainment Center") is a free and open source embedded operating system providing a complete appliance-like media center software suite that comes with a pre-configured version of Kodi (formerly XBMC) media player and third-party addons with retro video game console emulators and PVR/DVR plugins.

OpenELEC is an extremely small and very fast booting Linux based distribution, primarily designed to be booted from flash memory card such as USB-memory, SD-card, CompactFlash or a solid-state drive, similar to that of the Linux Live distributions but specifically targeted to a minimum set-top box hardware setup based on ARM SoC's or Intel x86 processor and graphics.

Over the years OpenELEC have and have had partnerships with several media player manufacturers and media center system integrates as OEM firmware developers, with OpenELEC maintaining the operating-systems on their hardware.
