I’ve already written a guide showing how to build and install Android in Radxa Rock. Today I’m going to build the Linux kernel, generate a Ubuntu server images based latest Ubuntu Linaro server release, flash the image to the NAND flash, and show how to install LXDE or XFCE desktop environment. If you are just interested in installing one of the latest supported images, you can download Android, dual boot (Android/Ubuntu), Ubuntu ALIP, and Router images for Radxa Rock @ http://dl.radxa.com/rock/images/, and skip “build” and “generate” instructions, and just follow the flashing instructions below. All steps in this tutorial will be done in Ubuntu 13.10, and lots of the instructions below follow hwswbits blog and Ubuntu Radxa Wiki. Build the Linux kernel Let’s start by building the Linux kernel. I’m assuming you’ve already install development tools in Ubuntu (e.g. apt-get install build-essentials). You can refer to the list at the beginning […]
Review of Beelink A9 RK3188 Android Media Player
Beelink A9 is an Android TV Box powered by Rockchip RK3188 SoC with 2GB RAM, and 8GB RAM (See full specs). The hardware is pretty standard, but the company released Android 4.4 SDK for the device, so when Beelink / Nexteon told me they wanted to send me one for review, I accepted. I won’t test the Android SDK today, but I’ll just show the pictures of the device, and run my usual series of tests for review. The shipped sample is not running Android 4.4 (beta), but Android 4.2.2. Unboxing Pictures I’ve received this Android media player in the no brand package below. I’m not sure if Beelink will sell directly to individuals, so you’ll likely to received some different if you order Tronsmart A928 or Zero Devices Z6C which are based on the same platform. There are quite a few accessories in the package: The box itself, a […]
Radxa Rock and ODROID-U3 Quad Core Development Boards Comparison
If you want a quad core development board for less than $100, you only have two choices right now: Radxa Rock powered by Rockchip RK3188, and Hardkernel ODROID-U3 powered by Samsung Exynos 4412 prime. There are also a few Freescale i.MX 6Q boards such as Wandboard Quad and UDOO Quad for around $130 which you could consider because of potentially better software support and features like SATA, but in this post, I’ll compare Radxa Rock and ODROID-U3 to help you decide which one may be right for your application or project. Let’s get right to the subject, with a side-by-side comparison table. Radxa Rock Hardkernel ODROID-U3 Comments Processor Rockchip RK3188 ARM Cortex-A9 quad core @ 1.6Ghz Samsung Exynos 4412 Prime quad core Cortex A9 @ 1.7 Ghz Slight advantage for ODROID-U3, but it’s basically a draw. GPU ARM Mali-400 MP4 GPU ARM Mali-400MP4 GPU @ 440MHz Same GPU, that’s a […]
Raxda Rock Development Board Unboxing, Quick Start Guide, and Benchmarks
Radxa Rock is an Android & Linux development board based on Rockchip RK3188 with 2GB RAM, 8GB NAND Flash, several I/Os that’s been available in beta version to a small number of developers in September 2013, with general availability starting at the very end of December 2013. Radxa team has sent me a board for me to try out. I’ll start with some unboxing pictures, write a Quick Start Guide for the first boot with Android 4.2.2, and run some benchmarks on the board. In another post, I’ll try some of the instructions to build Android and Ubuntu for the platform. Radxa Rock Unboxing Pictures & Video I’ve received the board in the following package via Fedex. Beside the board, we’ve got a Wi-Fi antenna, a USB power cable, and a plastic casing. Checkout Radxa Rock unboxing video below, if you want to find out exactly what’s you get when […]
Rockchip RK3288 vs RK3188 Performance Comparison
We were expecting some new processors at CES 2014, but this CES turned out to be mostly disappointing, and the vast majority of reporters present at the conference, do not seem interested in covering Chinese SoC vendors. Some information however surfaced on several foreign languages blogs and news sites about Rockchip RK3288. First, RK3288 is indeed based on ARM Cortex A12 as initially announced, and not some mysterious ARM Cortex A17 cores, but somebody at Rockchip likely made an embarrassing mistake, and Edward Weinert reported it was corrected at Rockchip booth with pieces of paper as shown below. So Rockchip RK3288 has four of these Cortex A12 core, a 4L2K H.265 / HEVC video decoder, and an high-end Mali T764 T624 GPU supporting OpenGL ES3.0 and OpenCL 1.1 that vastly outperforms Mali-400 MP4 found in RK3188, and is even significantly faster than Adreno 330 GPU found in Qualcomm Snapdragon 800 […]
How-to Use an Android mini PC to Edit and Print Documents, Spreadsheets, Presentations, and More
Android mini PC have come a long way, and for many use cases such as web browsing and online videos, they nearly match or even surpass the user’s experience you’ve got on a full blown PC. However, unless you’ve installed Linux on your HDMI TV stick or TV box, there were serious limitations using an Android device as a computer where you can install an office suite to create and edit text documents, spreadsheets, and presentation, and print them out. With the availability of apps such as AndrOpen Office, and the addition of printing support in Android 4.4 KitKat, it’s now possible to use Android mini PCs to create content and print documents just like in a normal PC. So if your kids need a cheap PC for their homework, you could just buy a $60 device, adding a USB keyboard and mouse, and connecting the device to an HDMI monitor. […]
What to Expect from AllWinner, Rockchip, Mediatek, and Other Silicon Vendors at CES 2014
CES 2014 is coming soon, and it will take place on 7 – 10 January, 2014, and we can expect some interesting SoC news. Samsung suggested they will unveil their 64-bit ARM SoC (Exynos 6?) at CES 2014, Nvidia will hold a press conference to “showcase new NVIDIA Tegra mobile technologies, gaming innovations, and advanced automotive display technologies”, and Qualcomm has been quiet for now. However, several Chinese SoC vendors, namely AllWinner, Rockchip, and Mediatek, have already announced what they will showcase at CES 2014, albeit with few details. AllWinner at CES 2014 Allwinner announced will showcase their OptimusBoard based on their Ultra Octa-Core A80 SoC, as well as 4G tablets powered by Allwinner A31/A31s, and dual-SIM phablets sporting A23 dual-core. Allwinner A80 is an Octacore processor featuring four ARM Cortex A7 cores, and four Cortex A15 cores @ 2.0GHz together with an unnamed GPU offering 2x more performance over previous […]
Beelink A9 Android TV Box Features Rockchip RK3188 SoC
Beelink A9, soon to be sold as Tronsmart A928 or Zero Devices Z6C, is a yet another RK3188 box with 2GB RAM, and 8GB Flash running Android 4.2, upgradeable to Android 4.4.2, and if it was not one of the four devices with Android 4.4.2 SDK I may not have decided to write about it. But since it should be more easily hackable with the SDK release, although with caveats, it becomes much more interesting. A9 Specifications: SoC – Rockchip RK3188 quad core Cortex A9 @ 1.6Ghz with Mali-400MP4 GPU @ 533MHz System Memory – 2GB DDR3 Storage – 8 to 16 GB eMMC flash + microSD slot (up to 32GB) Video Output – HDMI Audio I/O – HDMI, S/PDIF, 3.5mm audio out jack, built-in MIC. Connectivity – 10/100M Ethernet, dual band Wi-Fi 802.11 b/g/n, and Bluetooth 4.0 USB – 3x USB 2.0 host ports, 1x micro USB OTG port […]
