Giayee Atom PC is a Rockchip RK3288 Mini PC with a VGA Port, Multiple Placement Options (Crowdfunding)

You may know that Rockchip and Intel have a partnership to design Atom Sofia processors, but Giayee Atom PC has nothing to do with this initiative at all, and it’s just a pretty standard Rocchip RK3288 based mini PC, except it includes a VGA port, and various “placement” options namely horizontal position, vertical position, and TV/monitor mount. Atom PC specifications: SoC – Rockchip RK3288 Quad Core Cortex A17 up to 1.8GHz with ARM Mali-T764 GPU supporting OpenGL ES1.1/2.0/3.0, Open VG1.1, OpenCL, DirectX11 System Memory – 2GB DDR3 Storage – 8 GB NAND flash (16 to 32 GB optional) Video Output- HDMI up to 1080p (no 4K?), and VGA up to 1920×1080 @ 60 Hz Audio Output / Input – HDMI, 3.5 mm jacks for Audio In and Out Connectivity – 10/100M Ethernet, 802.11 b/g/n Wi-Fi.

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:

WeTek Play Android & Linux DVB-S2 / DVB-C/T/T2 Receivers are Now Available for 109 Euros

I reviewed Wetek Play Android media player with a DVB-S2 tuner this summer, and although I found it pretty good for a dual core media player, and liked its PVR functions, more work was needed to fix several bugs, and improve “WeTek Theater Live TV” app. Several months later, they must consider their devices ready, as they’ve now launched their online store selling the DVB-S2 and DVB-C/T/T2 versions for 109 Euros, and a version without DVB tuner for 99 Euros, all including free shipping worldwide. Let’s remind us of the specifications: SoC – Amlogic AML8726-MX dual core Cortex A9 @ 1.5GHz with a dual core Mali-400MP GPU System Memory – 1GB DDR3 Storage – 4 GB NAND flash + 1x micro SD slot Video Output – HDMI, AV (CVBS + R/L audio) Audio Output – HDMI, AV, and optical S/PDIF Tuners – DVB-S2, or DVB-C/DVB-T/DVB-T2 depending on model with two […]

PopMetal Rockchip RK3288 Development Board Features Multiple Display Interfaces (HDMI, VGA ,eDP, LVDS, MIPI), GPS and NFC Connectivity

Up to now, we’ve had mainly two development boards based on Rockchip RK3288 Cortex A17 processor: Firefly-RK3288 is a low cost development board powered by Rockchip RK3288 processor selling for as low as $140 shipped, and Radxa Rock 2, a more professional and expansive solution with dual Ethernet, 3G modem and so on. A third RK3288 board has now surfaced which offers a middle ground between Firefly and Radxa boards. PopMetal development board comes with 2GB RAM, 8GB eMMC, 5 video outputs / display interfaces namely HDMI, VGA, embedded DisplayPort (eDP), LVDS, and MIPI DSI, as well as the usual Gigabit Ethernet, Wi-Fi, and Bluetooth connectivity, complemented with GPS and NFC. PopMetal technical specifications: SoC – Rockchip RK3288 quad core ARM Cortex-A17 processor @ 1.8Ghz with ARM Mali-T764 GPU with support for OpenGL ES1.1/2.0/3.0, OpenVG 1.1, OpenCL 1.1, DirectX 11 System memory – 2GB DDR3 Storage – 8 GB eMMC, […]

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 […]

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 […]

Hardkernel ODROID-C1 is a $35 Development Board Powered by Amlogic S805 Quad Core Processor

Amlogic S805 is a quad core Cortex A5 processor which has found it way into low cost devices such as MK808B Plus TV Stick which can be purchased for as low as $30, or full-sized TV box such as MXQ S85 or MINIX NEO X6. All this low cost devices are nice, but the full source code is not available in your want to adapt them to your need. Luckily, Amlogic releases both an Android SDK, and a buildroot for Linux with GPU and Video Processing Unit (VPU) support, so Hardkernel decided to go ahead, designed a board, and has just launched ODROID-C1 quad core development board for just $35, or the exact price of a Raspberry Pi Model B+, but with much greater specs. ODROID-C1 specifications: SoC- Amlogic S805 quad core Cortex-A5 processor with a Mali-450MP2 GPU (2x fragment cores + 2x vertex shader cores) System Memory – 1GB […]
