Ubuntu 14.04 and Slitaz on Radxa Rock

Various Android and Linux images are available on Radxa Rock download page, but if you’d like to get newer images or other options, two developers have provided binaries and posted instructions to get Ubuntu 14.04 and Slitaz operating systems, the later currently booting with Linux kernel 3.10. Naoki FUKAUMI has published a miniroot how-to install a Ubuntu 14.04 Core (minimal headless installation) on Radxa Rock and Radxa Rock Lite. Installation should be relatively easy as he provide the update.img for both board so your can use the usual method in Windows (RkBatchTool) or upgrade_tool in Linux. If you don’t have serial console, you’ll have need to flash the parameter file requiring RkAndroidTool in Windows, and the same upgrade_tool in Linux. If once the installation and configuration is complete, you want a desktop environment,you can always run “apt-get install lubuntu-desktop” to install LXDE. SliTaz is a lightweight Linux distribution. I previously […]

Selecting the Best Adobe Flash Player in Linux for x86 and ARM

I’ve had countless and recurrent crashes caused by Adobe flash plugin either in Firefox and Chromium, mainly while playing videos from YouTube or other online video services that still mostly use flash, instead of HTML5. Adobe flash death is certain, but up to now it has been soooo slow, so I doubt that thing will truly die any time soon, and unfortunately it will probably be with us for many years to come. To work around the issue, I started by enabling Youtube HTML5 player, and try to play embedded videos inside YouTube instead of the orignal website. I still had crashes from time to time, and this method did not help with other video services. So I decided to check out what I could do to fix the issue. When you go to http://www.adobe.com/software/flash/about/ you can check your flash version, and Adobe will also list the player version for […]

Mali-400 GPU Is Now Working in Linux for Rockchip RK3188 Devices

Accelerated 3D graphics in Linux with Mali-400 via OpenGL ES has been possible for nearly a year on RK3066 devices,  but there was no such support for RK3188. This week however, both Naoki FUKAUMI and omegamoon have reported OpenGL ES to work in in their respective RK3188 devices. I don’t know which device omegamoon used, but Naoki did so in Radxa Rock, and even posted instructions to build it yourself. They’ve mostly followed the work done by olegk0 for Rockchip, and Mali drivers build instructions provided in linux-sunxi community, and it can be summarize in 3 main steps: Cross-compile drm.ko, mali_drm.ko, ump.ko, mali.ko in a Linux machine Copy and load the four modules to your RK3188 based board or device. Install dependencies and binary Mali drivers from sunxi-linux in your Rockchip device Once this is done you can try some OpenGL ES demos such as esgears2 or glmark2-es to test […]

Getting Started with Raxda Rock – How to Generate and Flash Ubuntu Saucy Server and Desktop Images

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 […]

Getting Started with Raxda Rock – Building an Android 4.2 Image from Source

I’ve posted some pictures, and show some basics how to get started in my first post about Radxa Rock. Today, I’ll post my experience trying the instructions to build Android for Radxa Rock in Ubuntu 13.10. Many of the instructions are also valid for other RK3188 devices. The source code is currently located in a private git repository, and if you’re sure you want to get the Android source  code, you should send an e-mail to [email protected] to be granted access to their private repo. Within minutes, I’ve received an email with the subject “GitLab | Account was created for you” to register an account. You’ll then need to add an SSH key just like you’d do for Github. Assuming you’re already using a service like github, you should already have SSH key. Simply type cat ~/.ssh/id_rsa.pub, copy the output, and go to git.linux-rockchip.org/profile/keys, login if needed, and click on […]

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.
