Rockchip RK3288 is one of the most popular platforms for TV boxes, and while most boxes are sold with Android OS, it can also run various Linux distributions with two main caveats: 2D/3D GPU acceleration, and hardware video decoding by the VPU. It appears the last two have been worked on, as yesterday, I got tipped that Kodi 14.2 Linux was running on Ugoos UT3 and Radxa Rock2 Square. Since both hardware platforms showcased a Kodi port at the about same time, it’s probably safe to assume they use the same implementation (despite slightly different build dates May 29 vs June 6), which has been developed by “Marc” (or is it MAC?) using the Android libraries and libhybris for video decoding, raw2 device driver for 2D HW accelerated blitting and converting frames, and ARM OpenGL library, driver and examples, among other software packages. So let’s check the demos starting with […]
Ugoos UT3S is an Update to UT3 Android & Ubuntu TV Box with a Fan
Many people like ARM based media player because most of them run Android providing access too many apps available via Google Play Store, a similar experience to what they got used with phones and tablets, and also because they are small, inexpensive, and fanless. However, the latest ARM processors such as Rockchip RK3288, can get really hot, so most of the time CPU frequency needs to be limited to avoid overheating and stability, which reduces performance. Which may be why, Ugoos decided to launch UT3S mini PC, an upgrade to UT3 mini PC with a mini Fan placed on top of a larger heatsink. Ugoos UT3S specifications and look remain very similar to the original model: SoC – Rockchip RK3288 quad core CortexA17 @ 1.80 GHz + Mali-T764 GPU with support for OpenGL ES 1.1/2.0 /3.0, and OpenCL 1.1 System Memory – 2GB to 4GB DDR3 Storage – 16GB or […]
Best Android Mini PCs Awards of 2014
I’ve reviewed quite a few Android media players this year, and as 2014 comes to an end, I thought it might be worth writing a best of 2014. But it’s difficult to announce an overall winner since all have some flaws one way or another, I’ll classified by categories: Best Ethernet, Best Internal Storage, … a bit like for “Oscars ceremony awards, based mostly on objective results from my tests. However, and somewhat oddly for a media player, I won’t select any TV boxes based on their video playback capabilities, as so far I haven’t found one that can play most 4K / H.265 videos reasonably well in Kodi, and video playback tests are also subjective. This is obviously a flawed contest as they all are, because in order to be nominated, the media player must have been reviewed on CNX Software. But it should be fun anyway, so let’s […]
Android 4.4 and Ubuntu 14.10 Tested on Ugoos UM3 mini PC (Rockchip RK3288)
A few days ago I posted pictures of Ugoos UM3, a cute mini PC powered by Rockchip RK3288 quad core Cortex A17 processor, with 2GB RAM, 8GB internal storage, a few USB ports, and Wi-Fi 802.11 b/g/n/ac connectivity. There are so many Rockchip RK3288 based TV boxes and sticks on the market, that it has become difficult to differentiate, so Ugoos has decided to support not only Android 4.4 like all their competitors, but also Ubuntu 14.10, and they’ve provided an alpha release of dual boot Android / Ubuntu images for Ugoos UT3 and UM3 models. Yesterday, I flashed the latest Android/Ubuntu firmware for UM3, and tested the image, so today I can report my findings. First of all, I’d like to point out that I received an earlier sample with various flaws that I reported to Ugoos, and they’ve already committed to fixes: 5V/2A power adapter is not powerful […]
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 […]
Unboxing of Ugoos UM3 Android and Ubuntu ARM mini PC
Ugoos UM3 is another minic PC powered by Rockchip RK3288 SoC with 8GB storage, 2GB RAM. It has Wi-Fi, but no Ethernet, so it looks like the offspring between a full-sized TV box and an HDMI stick. The company sent me a sample for evaluation pre-loaded with a dual boot image with Android 4.4 & Ubuntu 14.10. I’ll start by unboxing, and opening the device, before testing the dual boot image another day. Ugoos UM3 Unboxing The company sent me the device via DHL in a package for RK3066 / RK3188 devices, but I guess end-users will get an update package that will probably look similar. I was surprised how tiny the device was when I first took it out of the box, and with a black body and red cover, it’s probably the cutest too. It comes with a 5V/2A power supply and corresponding USB to micro USB cable, […]
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: Dual boot (Android 4.4.2 – Ubuntu 14.10) – ut3_dualboot_0.1t.rar Ubuntu 14.10 only – ut3_ubuntu14.10_v0.1.rar Android 4.4.2 only – ut3_2.0.4.zip 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: […]
Rockchip RK3288 Temperature Testing and Antutu Benchmarks
There are many upcoming Rockchip RK3288 based devices, and in the listing the CPU frequency varies from 1.6 GHz to 2.0 Ghz. so it’s difficult to know exactly what to expect. Ugoos has done some testing with their UT3 board measuring temperature after Antutu benchmark for different CPU clock frequencies and fan/fanless combinations. The board comes with a rather tiny heatsink which may explain some of the results below. They also added a small fan on top in about half the tests to compare the temperature against an heatsink only solution. Without further delays let’s go through the results: Frequency Antutu Score Temperature (heatsink) Temperature (Back of PCB) Heatsink only Heatsink + fan Heatsink only Heatsink + fan 1.608 GHz 38655 67 °C N/A 70 °C N/A 1.704 GHz 39853 72 °C 50 °C 75 °C 60 °C 1.800 GHz 41440 83 °C 52 °C 85 °C 62 °C 1.920 […]
