How-to Install and “Hack” Linux on T428 or MK802 IV mini PCs

PicUntu 4.5 installer is probably the easiest method to install Ubuntu on a Rockchip RK3188 based mini PC, but if you want a little more flexibility I’ll provide another method to install Linux on T428, MK802 IV or compatible devices, as well as links to go further: dual boot Android / Linux, create your own official distro, status of Mali-400 GPU support in RK3188… The method below is not new, as it was posted by Linuxium (Ian Morrison) in Freaktab in September, but this is the first time I’ve taken the time and managed to run Linux on Rockchip RK3188, and I’ll provide some more detailed steps. Prerequisites Even though in some cases it’s possible to install Rockchip firmware from Linux, AFAIK the tools available in Linux lack supports for the parameter and loader files, so ironically, you’ll need a Windows XP/7/8 machine to install Linux in your mini PC.

PicUntu 4.5 Brings Ubuntu 13.04 to RK3188 mini PCs

At the beginning of the year, PicUntu had been released for Rk3066 HDMI TV sticks, but as quad core devices based on RK3188 became popular, work started as soon as the source code was available, and a preliminary version of Linux ran on some RK3188 devices in June. After 4 more months of development an installer for PicUntu 4.5 has been released to allow users to run a customized version of Ubuntu 13.04 on RK3188 HDMI TV sticks or set-top boxes such as T428 or Rikomagic MK802 IV. The installation procedure appears to be easier than earlier version, as there’s only one installer file (247 MB), and you can complete the installation to the NAND flash of your device with just 4 clicks. PicUnutu runs xfce4 desktop environment, supports more than 200 drivers, multiple file systems (nfs, ntfs, cramfs, cifsutils, smb…), lots of different USB devices, serial devices, GPS devices, […]

CheapCast Chromecast Emulator for Android (Beta) is Available for Download

Yesterday, I wrote developers were working on making any media App and any Android device compatible with Chromecast. Sebastian Mauer has taken care of the latter, by publishing CheapCast (Beta) in Google Play. Several people have been trying it successfully, including in iMito MX1 mini PC. I’ve been less lucky. I’ve tried it by running YouTube App in Zopo ZP900S smartphone (Android 4.0.4) with 4 devices: Tronsmart T428 – “Works” but the video won’t start playing. (Bug reported in Github’s issue tracker) [Update: It now works with the latest version in Google Play]. MK908 – Refused to install anything in Google Play today… (Older Android 4.1 firmware) Wandboard Quad – “Works” but the video won’t start playing. CX-01 – CheapCast will crash when playing video I can’t really play YouTube videos over 360p without buffering here, so the reason the video won’t start in T428 or Wandboard Quad might be […]

Ubuntu 12.04 Now Boots on Rockchip RK3188 mini PCs (T428, MK908, Rikomagic MK802 IV…)

After the release of the RK3188 Linux kernel source code last week, Ian Morrison (Linuxium) has managed to boot Ubuntu 12.04 with XFCE desktop on Tronsmart T428. However, as Tronsmart refused to release their source code, further Linux development is likely to happen on Rikomagic MK802 IV, because Rikomagic released the code for their device, so development work will be easier. AFAIK, this is the first time Linux boots natively on RK3188 devices, so it’s still early stage (no Wi-Fi, Bt or graphics acceleration), but if you still want to give it a try here are the instructions (for T428):] Create a SDCARD with an Ubuntu 12.04 root file system on it and ensure it is labeled as “linuxroot” (Visit Slatedroid for details) Flash your RK3188 minipc with rooted stock 4.1.1 ROM. (May not be needed if you ROM is already rooted) Boot Android, and install Android Terminal Flash t428-3.0.36-linuxium-test+-kernel.img […]

Quick 3D Game Performance Comparison – Rockchip RK3188 vs AllWinner A31 HDMI TV Sticks

When comparing SoCs, most like to look at the overall score, and as I mentioned this morning, Tronsmart T428 (based on RK3188) easily beats Kimdecent CS868 (Based on A31) in Antutu benchmark, the former scoring 15207 points against 10559 points for the latter, both using stock firmware, and similar resolution (1280×720 vs 1280×672). The difference in resolution is because the status bar was hidden in T428. If we look at GPU performance, both the 3D scores in Antutu are about the same for both devices: T428 CS868 2D Graphics 1549 998 3D Graphics 2696 2866 But according to an earlier GPU comparison post, PowerVR SGX544 MP2 should be much faster than Mali-400 MP4. So I’ve decided to perform two quick tests: Epic Citadel benchmark and Real Racing 3 game. T428 could render Epic Citadel 1.07 at 41.3 fps in high quality, but I failed to install Epic Citadel, either via […]

How to Play Games in Android mini PCs / STBs With a PS3 Bluetooth Controller

Android mini PCs ( HDMI TV dongles) are great to make your TV smart, and you may expect to be able to play Android games on your TV easily. The reality is that the keyboard and mouse, or remote controls used with those devices, are not suitable for games, and most games do not play at all. Of course, OUYA and GameStick projects will take care of this, as well as the recently available Project SHIELD ($349) , but if you already have one of those mini PCs, you may not want to spend the money for another device. Luckily there’s a solution, and with some efforts, you can play many games, but not all, with a PS3 Bluetooth controller connected to your Android mini PC or Set-Top Box. I decided to give it a try by buying “GOIGAME Rechargeable Bluetooth Wireless DoubleShock III Controller for PS3” for $16.60, which […]
