Dual Boot Ubuntu 14.10 / Android 4.4 Image Released for Ugoos UT3

There has been several Ubuntu images released for Rockchip RK3288 based devices, even dual boot Android / Ubuntu images, first thanks to Ian Morrison who published instructions to install Linux on RK3288 devices based on the work done by T-Firefly team, then Nagrace released a preliminary dual boot Android / Ubuntu for HPH NT-V6, Open Hour Chameleon can boot either Android or Lubuntu from an SD card, and more recently Ugoos released a dual boot Ubuntu 14.10 / Android 4.4 image for their Ugoos UT3 mini PC, as well as a demo video.

Three images are now available for Ugoos UT3:

As a side note, I love mega.co.nz links as the download speed usually maxes out my Internet connection bandwidth.

There are two files and one folder in the dual boot rar file:

  • AndroidTool_Release_v2.3 folder with the usual Rockchip Windows tool for flashing.
  • ut3_dualboot_Android2.0.4_Ubuntu14.10_v1.img – The actual firmware
  • manual_at.docx – Word file explaining how to flash the firmware.

That means you’ll need a computer or virtual machine running Windows to install the firmware.

I understand the dual boot image boots to Android by default, and if you want to switch to Ubuntu, you need to press the power button, and the menu options “Switch System” will switch the device to Ubuntu. Once in Ubuntu, you can switch back to Android by clicking on the Android icon shown in the screenshot above.
Android_Power_Menu_to_UbuntuThe Ubuntu distributions does not support 2D/3d graphics acceleration, not hardware video acceleration because the GPU / VPU drivers are not available for Linux, and nobody has done the work with libhybris to support Mali-T764 GPU, and whatever VPU is used in RK3288.

Nevertheless the system appears to run quite smoothly thanks to the quad core Cortex A17 (or A12?) processor, and the fast eMMC used in the board. 1080p video playback is possible using software decoding. In the video demo below, Ugoos demos their dual boot image, starting in Ubuntu by playing music, running LibreOffice, browsing the web with Mozilla Firefox, installing and running Gimp, playing two 720p videos fom a SAMBA share over Wi-Fi, laoding a board games, and it looks like a perfectly usable system. However, they did not try more challenging tasks like 1080p video playback, YouTube video playback, flash games, etc.. but it’s something I’ll probably try with Open Hour Chameleon. Finally, they show how to switch between Ubuntu and Android, and vice versa. It only takes 15 seconds to switch between Ubuntu and Android in the video, but I think that part must have been edited.
