ODROID-XU3 Lite Board Ubuntu Review – Setup, Usability, and Performance

After testing ODROID-XU3 Lite with Android 4.4, and finding a workaround to some HDMI issues, I could finally try out Ubuntu, or rather Lubuntu with LXDE instead of Unity, in Hardkernel low cost octa-core development board. I’ll start this review by explaining how to install and setup Lubuntu on the board, followed by running various program to test the system usability as a desktop computer with LibreOffice, Chromium, XBMC, and 3D graphics, and finally run some performance tests with Phoronix Test Suit, build the Linux kernel natively, and transcode a video with avconf. Setting Up Ubuntu on ODROID-XU3 Lite All firmware images for ODROID development boards, can be found on odroid.in website, and if you want Ubuntu 14.04 image, go to ubuntu_14.04lts folder, to select the latest firmware file for your board. The latest image for ODROID-XU3 (Lite) is currently ubuntu-14.04.1lts-lubuntu-odroid-xu3-20141105.img.xz, it’s the same for micro SD card or eMMC […]

How to Modify HDMI Output Parameters in Linux for ODROID-XU3 (Lite) Development Board

Good news, I’ve finally managed to make HDMI output in my ODROID-XU3 Lite development board work with the Ubuntu image after some more tweaking. So ODROID XU3 Lite Ubuntu review is coming in the next few days. But first, I’ll explain the few steps I went through, in case others experience a similar issue. I downloaded, extracted, and flashed the latest Ubuntu image to a micro SD card with dd to give another try at running Ubuntu on my board, but no luck, I still got that black screen, albeit the system boots properly, as I got the command line using the serial console. During my Android review of ODROID-XU3 Lite, I noticed the system would always revert back to 720p60 video output, and HDMI output settings can be selected in /media/boot/boot.ini with the following content:

I actually tried a few settings in my previous attempt but unsuccessfully. Now […]

Boot Ubuntu (Linux) or Android from an SD Card on Rockchip RK3288 Devices

There’s already a method to boot Android from an SD Card on RK3188 devices, which should work with all Rockchip RK3188 devices. Ian Morrison (Linuxium) has now provided a instructions to boot Linux or Android from a (micro) SD Card in Rockchip RK3288 based devices, leveraging work from linux-rockchip community, and especially naobsd. The Android flashing method is slightly different between RK3188 and RK3288, because most Rockchip RK3288 devices make use of eMMC flash, while older Rockchip RK3188 products feature NAND flash, and it appears Rockchip RK3xxx boot priorities (in the BootROM stored in the SoC itself) are as follows: eMMC, SD card, and NAND flash. All that means is that an updated version of the bootloader is needed which looks for a bootable SD card, and although very unlikely, your device could end up being bricked during this procedure. This is not a problem for Open Hour Chameleon since […]

How To Upgrade Firmware on Ugoos UM3 mini PC

Ugoos released two new dual boot Android / Ubuntu images for Ugoos UT3 and UM3, which reduces the size of the system by 300MB, includes LibreOffice, replaces Firefox by Chromium + PepperFlash plugin, and fixes various bugs: ut3_dualboot_v0.2.rar – For UT3 full sized TV box UM3_dualboot_v0.2.rar – For UM3 mini TV box The firmware update procedure for Rockchip RK3288 is well-known, and Ugoos even includes a word file with flashing instructions in Microsoft Windows with the firmware images. However, it still took me about one hour to find out how to do with Ugoos UM3, so I thought I’d write a post in case others encounter the same issue. I flash the firmware in Ubuntu, so instead of using Android Tool, I flashed it with upgrade_tool command line utility I got from Orion R28 SDK, but you can also download Linux_Upgrade_Tool_v1.2.tar.gz directly. First let’s enter recovery mode. The procedure is […]

Create-android-sdcard Script Creates a Bootable SD Card for any Rockchip RK3188 Devices

Bootable Linux SD card images for some Rockchip RK3188 devices such as MINIX NEO X7, MK809III, Tronsmart T428 have already been released this summer, and it provided any easy way to try Linux on Rockchip RK3188 devices without messing with your Android installation. But now you can create Android bootable images with any Rockchip RK3188 devices thanks to create-android-sdcard script written by Ian Morrison, as long as you have the firmware for your Android mini PC, and I don’t see why it would not even work for tablets. It allows you to try Android firmwwre before replacing your existing installation (great for developers), and it can also be a way to handle multiple users on a single device. There could be one SD card for dad, one for mum, and one for the kid, and all you have to do is to take out and replace the SD card with […]

Handbrake 0.10 Supports H.265 and VP8 Video Encoding

HandBrake is an open-source video transcoding tool that I use each time I upload a video on YouTube, simply because it will let me crop the beginning or end of a video as needed, can make web optimized videos, has an easy to use user interface, and greatly reduces the size of the video shot with my camera. HandBrake 0.10 has now been released, and it adds H.265 and VP8 encoding support via respectively x265 v1.4 and linbpx, as well as QuickSync video support, but the latter only in Windows. There are also various other changes include OpenCL accelerated scaling. Handbrake is available for Windows, Mac OS X, and Ubuntu operating systems. It’s part of Ubuntu repository, but if you want the latest version, and support for MPEG-4 (m4v), you’ll need to install it from a PPA:

I’ve tested with the video I shot yesterday, to see if I […]

ODROID-XU3 Lite Development Board – Android Setup and Benchmarks

It’s been nearly ten days since I make ODROID-XU3 Lite unboxing, and my plans to first test Linux on the board were thwarted due a problem with HDMI. Luckily, after several attempts I managed to boot the board with Android. So today, I’ll show how to install or update Android on the board, and run a few benchmarks. But since there’s always a silver lining, I’ll start buy writing a bit about the HDMI issue, as I learned a few things on the way. HDMI Output Tribulations ODROID-XU3 Lite looks like a nice and powerful kit, and it may be one of the most cost effective ARM board on the market since it comes to performance to price ratio, so I was excited to try it, but as you know if you’ve read my unboxing post I did not work quite as planned, as all I got was a black […]

How-to Install Ubuntu on Allwinner A80 Powered pcDuino8 and A80 OptimusBoard

Last month, pcDuino released Android 4.4 and Ubuntu images for pcDuino8 board powered by Allwinner A80 octa core processor, and since it’s the same board layout as A80 OptimusBoard, I decided to try it out, but it failed as the update script would try to flash it to a partition that’s too small for the root file systems. But last week, Ian Morrison and Minidodes gave it another try, and successfully booted Ubuntu, or more exactly Lubuntu, on A80 OptimusBoard. Both their screenshot reports sun9i platform in /proc/cpuinfo, so that’s definitely Allwinner A80, but only one core is shown. I’m not sure if it’s because the other are idled and don’t show, or for some reasons, the kernel only supports one core at this stage. Anyway, here’s how they did to install Lubuntu: Flash the kernel (pcduino8_kernel_livesuit_20141008.img) with PhoenixCard or Livesuit first. See instructions to use Livesuit with A80 OptimusBoard.
