Picuntu Home://io Edition Brings GPU Acceleration to RK3066 based Mini PCs

Earlier this year, Picuntu (RC2), an Ubuntu-based distribution, was released for RK3066 powered HDMI dongles such as MK808, UG802, etc… More work has been going on since them, and Justin Gross (JustinTime4Tea) announced the release of Picuntu Home://io edition on SlateDroid. This distribution is based on Pictuntu RC3, supports GPU hardware acceleration, and lots of packages including Quake 3. GPU acceleration has been available since February thanks to olegk0, but I think it may be the first time it’s packaged into an installation image. Justin added a lot of goodies in this image including: Gaming – PCSX_rearmed Playstation Emulator and ioquake3 (with free demo files, replace with your own original Quake3 CD files) both supporting PS3 controller. Other games include GLTron, Solitaire, B.A.L.L.Z and a few more. Web Browsers – Midori, Firefox, and Chromium with support for Flash Graphics Tools – GIMP, Scribus, Inkscape, ImageMagick, etc… Email & Messaging Clients […]

MK808 mini PC gets Android 4.2.2 Beta Firmware

Last week, Geekbuying announced the first release of Android 4.2.2 for MK808, with support for MK808B coming soon. They warn users that it’s still beta since this is the first time Android 4.2 is available on Rockchip RK3066 mini PC, however I could not find user’s complains in the comments section, but at least one users in ARMTvTech is disappointed by this release. You’ll find three download links: Android 4.2.2 for MK808 (dropbox) – Currently unavailable due to heavy traffic Android 4.2.2 for MK808 rooted (Gdrive) – Same version as above but rooted by deadhp1 RKBatchTool  1.5 (dropbox)- Windows tool to perform the upgrade. Currently unavailable but there are alternate links. Once you get the files, you can follow the instructions showing how to upgrade MK808 firmware, or watch the video showing the upgrade process. MK808 is another device I don’t own, so I haven’t been able to try it […]

How to Access the Serial Console in MK808 mini PC

Omegamoon has done a pretty neat hack on MK808 Rockchip RK3066 mini PC to connect a Sparkfun USB to TLL board and access the serial console for bootloader and kernel debugging. The first thing he had to do was to open the device, remove the heatsink, and locate the Rx/Tx pads on the board. The Rx and Tx pins are accessible through pads, not via through holes, so it’s just a little more difficult to solder, but nothing too challenging. He and his brother also soldered another cable to the ground. Then they inserted a 6-pin header via the ventilation holes of the device, soldered the 3 wires to the header, and fix the latter to the casing. Finally, they just inserted the debug board in the pin header, connected the USB cable to their PC, and started minicom (or equivalent) to start accessing the serial console. I think that […]

PicUntu – Rockchip RK3066 Linux Distribution for mini PCs (UG802, MK808, …)

Many people are using RK3066 mini PCs because they currently offer the best performance to cost ratio, but until now they were mainly limited to Android Jelly Bean, although there was some preliminary port of Ubuntu available for the devices. Now, this preliminary port has become a specific Linux distribution for Rockchip RK3066 PCs-on-a-stick called PicUntu, which is based on Ubuntu 12.10, and can optionally support Xfce or Gnome desktop environments. This distribution is known to work on UG802 and MK808, but should also work on some other RK3066 mini PCs such as iMito MX1. The latest version is Picuntu 0.9 RC 2.2, and features such as WiFi, Ethernet, HDMI audio, USB webcam are known to work,  What you won’t get, however, is hardware video decoding and GPU support since Rockchip does not provide the relevant binary files for Linux, but this does not seem to stop the developers from […]

GPUs Comparison: ARM Mali vs Vivante GCxxx vs PowerVR SGX vs Nvidia Geforce ULP

I’m always very confused when it comes to comparing GPUs in different SoCs, and I could not really find comparisons on the web, so I’m going to give it a try even though, as you’re going to find out, it’s actually quite a challenge. There are mainly 4 companies that provide GPUs: ARM, Imagination Technologies, Vivante and Nvidia. [Update: Two comments  mentioned Qualcomm Adreno and Broadcom VideoCore are missing from the list. Maybe I’ll do an update later]. Each company offers many different versions and flavors of their GPU as summarized below. ARM Imagination Technologies Vivante Nvidia Mali-400 Series: Mali-400 MP Mali-450 MP Mali-600 Series Mali-T604 Mali-T624 Mali-T628 Mali-T658 Mali-T678 PowerVR SGX Series 5: SGX520 SGX530 SGX531 SGX535 SGX540 SGX545 PowerVR SGX Series 5XT: SGX543MP1-16 SGX544MP1-16 SGX554MP1-16 PowerVR SGX Series 6: G6200 G6230 G6400 G6430 G6600 2D graphics: GC300 GC350 3D graphics: GC400 GC800 GC1000 GC2000 GC4000 ULP GeForce (Tegra […]
