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 […]

Using an Android Mini PC as a Desktop PC (Blogging Version)

I use an x86 computer running Ubuntu 14.04 as desktop PC, spending most of my time working on this blog, which mostly involves reading and writing articles in web browsers (Firefox, Chrome), handling emails, communicating via Social networks, manipulating and editing pictures. But for reviews, I also need to take pictures and videos, tranfer these to my PC, and upload videos to YouTube. When I create tables, I normally type them in LibreOffice Calc, and copy/paste the results in WordPress editor. But this post side, I’ve put my noisy PC aside, and I’m writing from an Android 4.4 TV box, namely Probox2 EX, in order to evaluate how convenient, or not, Android may be for simple computing needs. First let’s indentify some applications used in desktop operating systems such as Windows and Linux (Ubuntu 14.04), and their equivalent in Android. I made the comparison table below in AndrOpen Office (AOO), […]

WRTNode is a Hacker-Friendly Open Source Hardware OpenWRT Wi-Fi Module Selling for $25

There are now some tiny and low cost ($15 to $20) Wi-Fi modules supporting OpenWRT such as VoCore and AsiaRF AWM002. However due to their small size they may not be that hacker’s friendly as they can’t have 2.54mm headers due to heir small size, and I’ve recently received AsiaRF AWM002 only to find out it not only needs 3.3V supply voltage, but also 1.8V and 1.2V. So I’d need to make my own power circuit with the required LDOs, or purchase a $20 base board to use the module. Here comes WRTnode another larger Wi-Fi module but with more usable 2.54mm headers, and based on the more powerful Mediatek MT7620N processor @ 600MHz. WRTnode hardware specifications: Processor – Mediatek  MT7620N 600MHz MIPS CPU (MIPS24KEc) System Memory – 64MB DDR2 Storage – 16MB SPI flash Connectivity – Wi-Fi 2T2R 802.11n 2.4 GHz up to 300Mbps Expansion Headers – 2x with […]

XBMC 13.2 Gotham Final Release

XBMC developers have just released XBMC 13.2, which could be one of the latest, if not the latest release, under the name XBMC, before Kodi 14 makes it debut. Since it’s only a minor release (13.x), there aren’t any new features, only bug fixes, and it should be safe to upgrade from older 13.x release on various supported operating systems and probably, except possibly in some Android TV boxes where you may have a custom version of Android specific to your hardware / SoC. List of changes against XBMC 13.1: Fix audio problems with pass-through on OSX Crash in Android if an app is favourite, then uninstalled from system. Fix crash in Android when entering programs menu in some skins Bitstream conversion fix for some BD mkv iso rips Fix labelcontrols with autowidth set were always marked as dirty (re-render) Update included PVR add-on Set “remote as keyboard” default to […]

I’ve already published an unboxing post for Probox2 EX, so today I’m going to test the firmware, including overall performance and stability, video playback, gaming, and most hardware features, as well as Remote+ air mouse with audio and gaming capabilities, which comes with the device. First Boot, Settings and First Impressions I’ve found two AAA battery to insert into Remote+ air mouse, connected an HDMI cable, an Ethernet cable, the Wi-Fi antenna, the RF dongle for Remote+, and the power adapter to […]
