One of the main issues with Linux on ARM is the lack of proper GPU drivers for the platform, as most silicon manufacturers now only focus on Android drivers which are not compatible with the Linux kernel, because Android is based on Bionic C library, whereas Linux is based on glibc or its variants. There are two ways to solve this issue: Open Source GPU drivers. This would be the ideal solution, as you would just be able to cross-compile the drivers for the proper, as well as fix bugs without having to ask the silicon manufacturer to fix the driver for you. Bionic to Glibc library. Such library acts like libdl, and allows to load Bionic library and overrides some symbols from bionic with glibc based ones. This is exactly what libhybris does. Ubuntu Touch is capable of using Android GPU drivers to run Ubuntu thanks to this library, […]
Sailfish OS SDK Adds Support for Windows and Mac OS X
At the end of February, Sailfish OS SDK Alpha was released with support Linux 32- and 64-bit only. The latest version of Sailish OS SDK can also be installed in Windows and Mac OS X. If you’re developing in Linux, it’s just the same SDK as released in February. The SDK and quick start guide is available from Sailfishos.org, or you can click directly on the links before to download and install the SDK. Windows SDK installer – SailfishOSSDK-windows-offline.exe Mac OS X installer – SailfishOSSDK-mac-offline.dmg The SDK is still at the Alpha stage with several known issues, and probably a few more yet-to-be-known bugs.

PengPod 700 Linux Tablet Used As a 3D Printer Touchscreen Controller
PengPod 700 & 1000 are two of the rare Linux tablets to be available on the market. Those tablets are based on AllWinner A10 SoC which can support both Android and Linux thanks to independent developers. After a successful Indiegogo campaign, where they managed to received pledges for a few hundred units of both model, people started to receive their Linux tablets earlier this year. Francesco Santini decided to purchase PengPod 700 in order to use it as an touchscreen controller for his 3D printer (Solidoodle). He modified Pronterface, a graphical user interface written in Python to control 3D printer, for the 7″ display the of PengPod tablet, and made the change available in his github account https://github.com/fsantini/Printrun-pengpod700. He uses a SAMBA share to copy G-code files (“G-code is the common name for the most widely used numerical control (NC) programming language”), and load the required file from the PengPod […]
AllWinner A20 Linux Source Code, EVB Schematics and Product Brief
Hardware based on AllWinner A20 such as Cloudsto Media PC PRO DRIVEDOCK, should start to be available soon, and resources for developers have been slowly released (or leaked) to the community. AllWinner A20 Source Code The source code for AllWinner A20 and A31 has been released to sunxi-linux a while back, and they have started to clean up the code before hardware becomes available. The code apparently hasn’t made it to sunxi-linux github account just yet, but Linux for A20 has been imported into github at https://github.com/amery/linux-allwinner/tree/import/lichee-3.3/a20-dev. AllWinner A20 is known as sun7i in the code. AllWinner A20 Evaluation Board Schematics and Product Brief Olimex received A20 EVB schematics and product brief from AllWinner earlier this week, and as usual, they promptly uploaded those documents to their github account. The 3-page product brief does not bring anything new, and the data sheet does not seem to be available right now. […]

Wandboard Releases Updated Android and Ubuntu Linux Images and Source Code
Since I’ve received my previous short review of the Wandboard Dual development board, there has been more work on done the platform with new Android and Ubuntu images, Jelly Bean source, Linux SDK release, and git repo setup. I’ve tried the binary images, and had a quick look at the source code and corresponding documentation. Android 4.1.2 Image and Source Code Wanboard has release an improved Android image on the 14th of March which you can download for both Solo and Dual version of the development board with the following Changelog: Fix HDMI audio/playback issue with certain monitor. Add support for wifi on wandboard-dual. Known issue: Might need to turn off “Avoid poor connections” in Wi-Fi ->Advanced to keep connection alive. I’ve given it a try in Wandboard Dual, and it seems Ethernet support is gone (Sorry my mistake, Ethernet IS working, but there’s no indication when it’s connected, and […]
Undistract-me Sends An Alert For Time-Consuming Commands in Linux
In Linux, some commands executed in the terminal such as make, wget, dd may take a while, so usually you’d just let them run in the background, and do some other work, drink tea, go for nap… while they are running, and come to check from time to time if the command has completed. Sometimes I even forget I run a particular command, and realize it has completed a few hours ago… It’s possible to add some command at the end of your command line, but it can be cumbersome, and you may forget to do it. The best would be automatic alerts for commands that take a long time, and undistract-me just takes care of that by sending an alert for commands that take more than 10 seconds (by default). In Ubuntu 12.04 and 12.10, you can install undistract-me as follows:
1 2 3 |
sudo add-apt-repository ppa:undistract-me-packagers/daily sudo apt-get update sudo apt-get install undistract-me |
Undistract-me is part of Ubuntu 13.04 or […]
Linaro 13.03 Release with Linux Kernel 3.9 and Android 4.2.2
Linaro 13.03 is now available, and features Linux Kernel 3.9-rc3 and Android 4.2.2. This month, Linaro has released their first Origen Quad Android image, as well as Tiny Android build for Arndale. The ALIP image listed in the download page is still based on Ubuntu 12.11, but as doc Bormental noticed earlier this month, the latest ALIP Quantal 13.03 image is available for download at https://releases.linaro.org/latest/ubuntu/quantal-images/alip. Some development tools (gcc, g++, vi, make..) are now included in Android, so you can develop and build natively from your Android device. Linaro has kept on cleaning the Linux kernel ARM tree for Exynos and ST Ericson SoCs. More work has been done on big.LITTLE for both IKS and HMP, as well as ARMv8 OpenEmbedded, and an initial GRUB port on ARM UEFI is now available. Here are the highlights of this release: Automation and Validation A simple CLI tool for communicating with […]
