Cubieboard 4 Ubuntu Review – Setup, Usability, and Performance

Cubieboard4 is a development board powered by Allwinner A80 octa-core processor with 2GB RAM and 16GB eMMC. I’ve already shown how to get started with the board using the pre-installed Android 4.4 image, and run some benchmarks in Android, so now it’s time to check out the Ubuntu Linaro 14.04 image provided by CubieTech. I’ll show how to install and setup Ubuntu 14.04 on the board using a micro SD card, run desktop applications like Chromium, Libre Office, and son on on the board, and complete the review with some Linux benchmarks. Setting up Ubuntu on Cubieboard4 Firmware images for Cubiebord4 can be downloaded @ http://dl.cubieboard.org/model/cc-a80/Image/. Currently Android 4.4, Debian server, Ubuntu Linaro server, and Ubuntu Linaro desktop with LXDE desktop environment. That’s the latter I’ll use for the experiment, and two images are available: linaro-desktop-cb4-card-hdmi-v0.4.img.7z – Bootable image from micro SD card linaro-desktop-cb4-emmc-hdmi-v0.4.img.7z – Installation image to eMMC to […]

Linux 3D GPU Acceleration Demo on Rockchip RK3288 based Firefly Board

Several devices and development boards based on Rockchip RK3288 processor already support Linux, usually with images based on Ubuntu, including Ugoos UM3 / UT3, Open Hour Chameleon, and Firefly-RK3288 among others. What these images lack however, is support for 2D and 3D graphics acceleration with the GPU, and hardware video decoding/encoding with the VPU. But Jas-hacks has made some progress with 3D graphics support. He has managed to add GPU acceleration via EGL/OpenGL ES bringing 3D acceleration to the platform, but 2D support is not there yet, meaning X11 still heavily relies on software rendering. But the implementation is still good enough to run the usual es2gears and glmark2-es2 benchmarks. as well as some WebGL demos in Chromium. Performance is currently underwhelming, with 50 points in glmark-es2, even a bit lower than the score (54 points) I got with ODROID-X board powered by Exynos 4412 SoC with a Mali-400MP4 GPU, […]

CubieTruck Metal Case Kit Getting Started Guide and Review

I’ve received CubieTruck Metal Case kit just over a month ago, but just like for Ubuntu on ODROID-XU3 Lite, the board could not get HDMI EDID info from my Panasonic TV, which led to a crash at boot time. CubieTech has now fixed the issue, so I’ve finally been able to complete the review with Cubieez (Cubie Easy) distribution, pre-installed on the board, and based on Debian 7.6. You can get the full hardware specs on my previous post, but the kits is comprised of four parts: CubieTruck development based on Allwinner A20 dual core processor, a rugged metallic enclosure, a 128GB SSD, and a 5,300 mAh battery acting as a UPS. I’ll start by showing how to setup the board, test SATA and Gigabit Ethernet performance, check if the battery acts as expected, try to use the board as a desktop replacement with LibreOffice, Chromium, and so on, and […]

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 […]

Rikomagic MK902 II Android TV Box with Rockchip RK3288 Coming Soon

Rikomagic MK902 is an Android mini PC powered by Rockchip RK3188 quad core processor, and there’s even a Linux version. The company has announced it has been working on an upgrade of the device named MK902 II, and powered by Rockchip RK3288. It will initially sell with Android, but I would not be surprised with a PicUntu version is also sold later, and even an MK 902 II Chromebox could hit the market, since Rockchip released Chromium OS overlay files for RK3288. They’ve also provide MK902 II specifications: SoC – Rockchip 3288 quad core ARM Cortex A17 up to 1.8 GHz with Mali-T764 GPU System Memory – 2G DDR3 Storage – 8 or 16 GB flash + micro SD slot (up to 32GB) Video Output – HDMI, AV Audio Output / Input – HDMI, stereo audio (via AV port), optical S/PDIF, microphone Video Codecs – MPEG-1, MPEG-2, MPEG-4, H.263, H.264, […]

Linux Kernel Source Code and Chromium OS Overlay for Rockchip RK3288

A few days ago, we’ve seen Chromium OS running on Rockchip RK3288 development platform. I’ve been informed the source code could have already been released via the newly registered rkchrome github account with Linux kernel 3.10.30 and the overlay files to build Chromium OS for RK3288. There’s also a u-boot repository but it is currently empty. This Linux kernel can also boot Rockchip RK3188 based Radxa Rock development board, but more tests are needed to see if it’s really usable. I’ll have a look at the Linux kernel, and try to build it, and leave the Chromium OS part for later or other people. Let’s retrieve the source code:

git clone https://github.com/rkchrome/kernel.git
cd kernel

1 2	git clone https://github.com/rkchrome/kernel.git cd kernel

We’ve got two kernel config files related to Rockchip in arch/arm/config:

ls arch/arm/configs/ | grep rock
rockchip_chromium_defconfig
rockchip_defconfig

ls arch/arm/configs/ | grep rock

rockchip_chromium_defconfig

rockchip_defconfig

But since this is a recent 3.10 kernel with support for Flattened Device Tree support, and multi-platform support, there’s not much to be seen in these files, and […]
