How to Install PHP 5.6 (and Xibo Digital Signage CMS) in Ubuntu 16.04

Xibo is an open source digital signage using a client / server architecture, and in the past I wrote a tutorial showing how to use it, and ran Xibo Python client on ARM Linux TV box, but with software handling only so rendering scrolling text was not very smooth at all, and video decoding was not really possible. But now I have Star Cloud PCG02U Intel TV stick which costs just $70 shipped with Ubuntu 14.04, and that I have upgraded to Ubuntu 16.04, and I thought that would be a great low cost Xibo Linux client which should have pretty good performance. I started by installing Xibo server, only to find out that the cross-platform Python client had been phased out, with now only Windows and Android clients available. So I canceled my plan. I still had some challenges installing Xibo server on Ubuntu 16.04, so I’ll report my […]

Raspberry Pi 3 Repository Has Been Added to Android Open Source Project

Android has been ported to the Raspberry Pi boards in the past, but the images were not really usable because the implementation lacked 2D & 3D graphics support. The good news is that Raspberry Pi 3 is likely to officially support the latest version of Android soon, because rpi3 repository has been created in AOSP about 5 weeks ago. That’s all we know for now. Raspberry Pi 3 could then be part of the second wave of boards officially supported in Android “mainline”, as currently 96Boards Hikey is the only supported board in AOSP. However, If we go down in the git repo to android/device, we can also see MIPS Creator CI40, Aaeon Upboard, i.mx6ul picoimx board, Intel Edison and Minnowboard, and a few others. Some of the boards will run Brillo instead of Android however, or it could be a different project, so we’ll have to see what happens […]

Preliminary Open Source Bootloader for Raspberry Pi Boards Released

Raspberry Pi boards require a closed-source binary to boot. I understand it this is handled by VideoCore IV GPU, and so far the Raspberry Pi foundation are not release source code for the bootloader, possibly due to legal reason (e.g. NDA to Broadcom). But I noticed people chatting about an open source bootloader for Raspberry Pi on sunxi-linux IRC channel. The bootloaded called rpi-open-firmware has been developed by Kristina Brooks (christinaa), who previously did some work on the VideoCore IV GPU, as you can see on her blog and github account. Kristina describe the project as follows: This is a small firmware for RPi VPU (VideoCore4) versions 1/2/3 that is capable of initializing VPU PLL (PLLC), UART, SDRAM and ARM itself. It’s intended to be used instead of stock bootcode.bin on RPi’s SD card. You need to have UART to see anything meaningful as far as output goes. This has […]

OpenThread is an Open Source Implementation of Thread IoT Networking Protocol

Thread was announced about two years ago, as a new IP-based wireless protocol based on 6LoWPAN and 802.15.4 standards and targeting IoT applications. Nest Labs, an Alphabet company, has now released OpenThread open-source implementation of the networking protocol under a BSD license. The source code (C++) for OpenThread includes supports for End Device, Router, Leader & Border Router roles, and can be found on Github. The implementation is said to be OS and platform agnostic with a radio abstraction layer, have a small footprint, and implement all Thread networking layers, namely IPv6, 6LoWPAN, IEEE 802.15.4 with MAC security, Mesh Link Establishment, and Mesh Routing. To quickly get started, you may want to read the Examples README which explains how to build the code, start two nodes, and ping them. Interestingly, while the code is there for everybody to use, only paid members ($2,500 to $100,00) of the Thread group can […]

LEDE (Linux Embedded Development Environment) Project is a Fork of OpenWrt

2016 appears to be the year of splits in open source communities with Kodi losing its main Android developer, LibreELEC being born out of disagreements within OpenELEC community, and now LEDE project, a fork of OpenWrt, has been created because some people are not satisfied with the way the project is managed, and now “includes a significant share of the most active members of the OpenWrt community”. LEDE, which stands for “Linux Embedded Development Environment” , has three stated goals: Building a great embedded Linux distribution with focus on stability and functionality. Having regular, predictable release cycles coupled with community provided device testing feedback. Establishing transparent decision processes with broad community participation and public meetings. You can find more on LEDE Project website, and the source code is available on the project’s git server:

git clone http://git.lede-project.org/source.git

Wandboard Development Boards Get Android 6.0 Marshmallow Support

Wandboard development boards powered by Freescale i.MX6 Solo, Dual and Quad Cortex A9 processors were released over 3 years ago with Android 4.1 Jelly Bean. Contrary to many other boards that don’t get an updated version, Wandboard boards got support for Android 4.4 Kitkat, Android 5.x Lollipop, and now the community has recently released Android 6.0 Marshmallow. You can try the Android 6.0 SD card image as follows:

wget http://download.wandboard.org/wandboard-imx6/android-6.0/wandboard-all-android-6.0.1-sdcard-20160428.zip
unzip wandboard-all-android-6.0.1-sdcard-20160428.zip
sudo dd if=wandboard-android-6.0.1-ga-20160428-sdcard.img | pv | sudo dd of=/dev/sdX bs=16M

wget http://download.wandboard.org/wandboard-imx6/android-6.0/wandboard-all-android-6.0.1-sdcard-20160428.zip

unzip wandboard-all-android-6.0.1-sdcard-20160428.zip

sudo dd if=wandboard-android-6.0.1-ga-20160428-sdcard.img | pv | sudo dd of=/dev/sdX bs=16M

Where /dev/sdX is the device for your SD card. If you can remember the first Jellybean release had separate images for each version of the board, but thanks to device tree implementation, a single image is now released with all three versions. The full source code is also available in a 5.0 GB tarball. Since Freescale, now NXP, i.MX6 processors will be available until November 2022, we can most probably expect a few more Android releases for the board. Jean-Luc Aufranc […]
