Linux (Enlightenment and Lubuntu) in WeTek Play Amlogic TV Box

Last week I reviewed WeTek Play, a TV box with two DVB-S2 tuners, powered by Amlogic AML8726-MX dual core ARM Cortex A9 processor, and running Android 4.2, but the company also released several Linux based images including one with Enlightenment window manager, and another, temporary one, with Ubuntu core which allows you to install Lubuntu or Xubuntu with apt-get. There are also working on OpenELEC, but have not released the binary yet. Today, I’ll try the Enlightenment image because it also supports hardware video decoding via Gplay (gstreamer), and show how to install Lubuntu. The instructions below have been done in a computer running Ubuntu 14.04, but a Windows computer can also be used. Download Wetek-Linux.img.bz2 Connect a micro SD card to your computer, extract and flash Wetek-Linux.img: In Linux using a terminal window:

bzip2 -d Wetek-LInux.img.bz2
sudo dd if=Wetek-Linux.img of=/dev/sdd bs=1M
sync

bzip2 -d Wetek-LInux.img.bz2

sudo dd if=Wetek-Linux.img of=/dev/sdd bs=1M

sync

In Windows, extract the image, and use Win32DiskImager to copy the image to your micro SD […]

How to Build and Run Android L 64-bit ARM in QEMU

[Nov, 2014 Update: The method below does not seem to work anymore, but a 64-bit ARM emulator “emulator64-arm64” has now landed in AOSP, and updated instructions are available here]. Most people can’t afford Juno Cortex A57/A53 development board, and mobile processors based on the latest 64-bit ARM cores are only expected by early 2015. But thanks to a small team at Linaro, you can now build and run Android L 64-bit ARM in the latest version of QEMU that supports Aarch64. Alex Bennée, an engineer working for Linaro, wrote a blog post in Linaro’s Core Dump blog explaining the Android emulator is actually based on QEMU, the differences compared to mainline QEMU, the work they’ve done on Android L at Linaro, and most importantly, provided the basic steps showing how to build and try Android L 64-bit ARM (ARMv8) in QEMU. I’ve just done that, but unfortunately, albeit the builds […]

XBMC / Kodi 14 Ported to Tizen 3.0 Wayland

XBMC, soon to become Kodi with version 14, is now supported in Linux, Windows, Mac OS X, Android, and iOS. But Kodi 14 may soon support Tizen, as Phil C., a Tizen developer, ported the alpha version of Kodi 14 to Tizen 3.0, and showcased it on an Intel “Bay Trail” NUC powered by Intel Atom E3815 single core processor. Intel 3815 NUC is officially supported by Tizen and an image is available for download, so most of the work was to build Kodi 14 Alpha, install required packages, and configure some scripts. The video below shows XBMC/Kodi 14 UI running on Tizen 3.0, and a video played from YouTube, and after about 3 minutes, he explains how to modify the BIOS to have the system boot and work properly for the rest of the video. If you happen to own an Intel E3815 NUC, but it could also work […]

How to Upgrade Firmware in Rockchip RK3288, RK3328, RK3399 Android TV Boxes

For some reasons, Rockchip is extremely fond of Windows based firmware tools, and instead of providing a simple SD card method, they’ve continued to use these awful tools to upgrade firmware for Rockchip RK3288, RK3328, RK3399 devices, and other Rockchip based TV boxes. I don’t mean to say these are useless, but they should not be used by end users, unless their device is bricked. Nevertheless, Rockchip has now release version 2.3 of their Android tools for Windows, and GeekBuying has published a guide showing how to do, which I’ll summarize below. Rockchip has also released an updated version for the Linux Upgrade Tool (upgrade_tool) v1.24 that allows you to do the update in Linux. [Update: The latest versions of DriverAssistant (Step 1) and AndroidTool (Step 2) can be found in Rockchip-Linux account in Github] The first thing to do is to make sure you’ve got the latest Rockchip USB […]

APK Downloader Retrieves an App APK with its Google Play Link

Let’s assume you are unlucky, and frequently end up with Google Play saying “Sorry, this app is not compatible with your device”. The usual way is either to patiently wait for a new firmware, or actually go through Android configuration files to change the behavior by, for instance, emulation a “Samsung Galaxy S4”. It’s also possible you somehow ended up with a device without Google Play. There’s now another solution thanks to APK Downloader. The way it works is that you just go to APK Downloader website, look for the app in Google Play website in your PC or device, copy the URL to APK Downloader website, and click on “Generate Download Click”. After a few seconds, or minutes depending on the APK size you’ll be able to download the APK. I used Antutu for testing as shown in the screenshot above. There’s a total limit of 250 new cached […]

DIY Power Measurement Board

When I review media player or development boards, I’m often asked about power consumption figures. One way to measure power consumption is to use a Kill-a-Watt, but for low power devices it’s not always accurate enough, and it also includes the heat dissipation from the power adapter, which may or may not be useful depending on what you want to measure. For USB powered devices or boards, an easy way to measure power consumption is to use CHARGER Doctor, a small $5 USB dongle that displays both voltage and current alternatively. Unfortunately, most products I’ve received lately use barrel type connectors, so this little tool has not been as useful as I hoped. The only solution is then to measure voltage and current with a multimeter. Voltage is measured in parallel, so you just need to point the multimeter’s leads where you want to perform the measurements. However, the current […]

How to Use an Android TV Box as a Wi-Fi Access Point

Today, I’ve come across another potential use case for Android TV boxes with Wi-Fi and Ethernet. Let’s say you are in a room with Ethernet, but there’s no Wi-Fi signal or the signal is too weak, and want to use your smartphone to connect to the Internet via Wi-Fi. If you don’t have one of these small (openWRT) Wi-Fi router with you, but instead brought an Android mini PC, you can configure the “Portable Hotspot” function to transform it into a secure Wi-Fi access point. Assuming you’ve connect an Ethernet cable, and powered the device, first make sure Ethernet is enabled\, and Wi-Fi is disabled in the Settings menu. To click on Settings->More.. in the Wireless & Networks section, and select “Tethering & portable hotspot” or simply “Portable hotspot” depending on your firmware. In the next menu, click on Portable Wi-Fi hotspot to enabled it, then “Set up Wi-Fi Hospot” […]

Easy and Safe Way to Try Linux on Popular Rockchip RK3188 mini PCs

Until recently, installing Linux on Rockchip R3188 based TV boxes or HDMI TV dongles meant you had to flash one or more binaries to your device using various type of tools for Linux or Windows. But thanks to various members of the community, it’s now as easy as flashing an image for the Raspberry Pi, as long as you own Minix Neo X7, PQ Labs iStick A350-SSD, Radxa Rock development board, or Rikomagic MK802IV (AP6210 or 8188EU Wi-Fi module versions) thanks to images provided by Ian Morrison on G+ mini PC community that can be booted from a (micro) SD card, which the added advantage that it won’t mess with your Android installation. You can do it whether you use a Windows or Linux PC, and it should also be possible on Mac OS X, but I don’t know the commands. Here are the steps to follow for MINIX NEO […]
