WeTek Play 2 Amlogic S905 TV Box Gets Ubuntu 16.04 Mate and Minimal Firmware Images

WeTek Play 2 is the latest TV box from WeTek with DVB or ATSC tuner, and powered by Amlogic S905-H processor. It ships with Android 5.1.1, but Ubuntu 16.04 Mate and Ubuntu 16.04 minimal firmware images have been released by the community. You can try Ubuntu 16.04 LTS Mate (with desktop environment) or the headless Ubuntu 16.04 LTS minimal image by uncompressing the images, and flashing them to a micro SD card with dd or Win32DiskImager. Two default credentials (username/password) are provided: wetek/wetek and root/wetek. This required the latest Play 2 Android firmware, so make sure you get the latest OTA update before trying Ubuntu. The Ubuntu 16.04 images should just boot from the SD card without replacing or affecting your Android installation. If this type of images for Amlogic S905 seems similar, it’s because are based on Hardkernel ODROID-C2 Ubuntu 16.04 images. You can find the Linux kernel for […]

Allo Sparky Audio Kit Combines an ARM Linux Board with Amplifier, Audio DAC, Reclocker and Capacitance Multiplier Boards

Last year I wrote about Allo Sparky SBC Linux and Android development powered by Actions Semi S500 quad core Cortex A9 processor, which mostly differentiates itself from the competition by the many add-on boards for audio, VoIP, and IoT (WiFi+Bluetooth+Zigbee ). While most of development boards are manufactured in China, Allo company is based in India, and all boards are manufactured there, which could be a benefit to Indian readers who want to avoid potential custom issues with other boards. The company has shipped me their complete audio development kit, and I’ll first check out the hardware, before taking time to experiment with the kit in a few weeks or months… I could find 6 different boards in the kit, which I detailed below, as well as a 5V/3A power supply with AU and EU adapter, a micro USB adapter, a micro SD card apparently pre-loaded with Ubuntu 12.04, a […]

Amlogic S905, S905X, and S912 Processors Appear to be Limited to 1.5 GHz, not 2 GHz as Advertised

When I compared the performance Amlogic S905 and Rockchip RK3368 processors last year, I noticed Amlogic S905 single thread performance not being much faster than the one of Rockchip RK3368, despite the former allegedly clocked at 2.0 GHz against the latter 1.2 GHz. But early this month one member (koschi) on ODROID forums started a thread entitled “No performance difference between 1.5, 1.75 & 2GHz” about ODROID-C2 board. The first post link to Ant-computing website about choosing a processor for a build farm, and one of the tables comparing various ARM and x86 processors with the claim that Amlogic S905 was listed to 1.536 GHz, because “the device claims to run at 2.016 GHz but the kernel silently ignores frequencies above 1.536 GHz!” So koschi did his own tests with 7z and sysbench, using cpufreq-set -u $FREQ to set a fixed frequency between test, and could confirm the issue:

NanoPi NEO Board Gets Armbian Debian 8 & Ubuntu 16.04 with Linux 4.6 & 4.7 (Mainline), h3consumption Power Consumption Tool

We’ve been blessed with a wide range of low cost Allwinner H3 boards thanks to Shenzhen Xunlong Orange Pi and FriendylARM NanoPi boards. Recently, armbian developers have been focusing on NanoPi NEO board, and they’ve now released Debian Jessie and Ubuntu Xenial with Linux 4.6.7 and Linux 4.7.2. The latter is mainline kernel with some patchsets for Ethernet. You can download the Linux 4.6.7 based “beta” images from armbian NanoPi NEO page, and selected the “Vanilla” versions, then flash then one a micro SD card as you would normally do. Linux 4.7.2 based “experimental” images with USB OTG support and schedutil cpufreq governor can be found on the separate server in a temporary directory. Thomas Kaiser explains further: Ethernet and throttling are working (the latter not as efficient as with legacy kernel but at least it protects the SoC from overheating). Please note that all vanilla kernel images currently suffer from […]

Magic Device Tool Helps You Switch Between Android and Ubuntu on Supported Phones

There have only been a few phones released with or supporting Ubuntu so far, and those phones will normally be able to run Android too since Ubuntu Touch relies on Android drivers, and you may decide that Ubuntu is not for you and switch back to Android, or the contrary, if you’ve purchased an Android phone, you may want to install Ubuntu instead. In order to simplify the task of installing operating systems, Marius Quabeck has developed “Magic Device Tool“. As you can see from the screenshot above, 13 phones and tablets are currently supported. You’ll need a computer with Ubuntu 15.04 or greater to install the tool, and I’ve done so on Ubuntu 16.04:

git clone https://github.com/MariusQuabeck/magic-device-tool.git
cd magic-device-tool
chmod +x launcher.sh
./launcher.sh

git clone https://github.com/MariusQuabeck/magic-device-tool.git

cd magic-device-tool

chmod +x launcher.sh

./launcher.sh

The script will also install phablet-tools if it is not already installed, so if you are not root, you’ll need your account to be member of sudoers. Once the initial setup is done, you’ll […]

Intel Unveils Joule Compute Module and Devkit for IoT based on Atom T5500 & T5700 Processors

As the Intel Developer Forum 2016 is now taking place in San Francisco, Intel has unveiled the Joule Compute Module and development kit targeting IoT applications. The module is not for low cost and low power sensor nodes however, as it features a powerful quad core Atom processor running at 1.5+ GHz, so it more suited to IoT gateways, or other application requiring lots of processing power to handle sensor data. Two models of the Joule module have been introduced: Intel Joule 570x platform SoC – Intel Atom T5700 64-bit quad-core processor @ 1.7 GHz / 2.4 GHz (Burst frequency) with Intel HD Graphics with 4K video capture and display System Memory – 4GB LPDDR4 RAM Storage – 16GB eMMC memory Connectivity – 802.11ac Wi-Fi with MIMO and Bluetooth 4.1 Other interfaces – USB 3.0, MPI CSI and DSI interfaces, and multiple GPIO, I2C, UART interfaces Intel Joule 550x platform […]
