Linux on ARM
Olimex has been working on their open source hardware TERES-I DIY laptop since last year. The laptop is supposed to come in kit form, so that you can build it yourself. Every board and most parts are open source to let your easily repair it, or improve it by adapting the part to your own needs.
The BSD-based, UNIX-like operating system OpenBSD has been recently updated to version 6.2, a release that introduces up-to-date components, better hardware support, and lots of security improvements.
I’ve just showed how to install Debian, and build a Linux image from source on VS-RD-RK3399 board (akak Mecool VS-RK3399) last week-end, but at the time I did not run any benchmarks on the board. We already have plenty of benchmarks for Rockchip RK3399 in Android, so instead I started by installing the latest Phoronix Test Suite in Debian:
Development of the Linux 4.14 kernel series continues with the second Release Candidate (RC) milestone, which Linus Torvalds himself announces this past weekend. The update brings more updated drivers and various improvements.
Earlier this year ASUS announced the Tinker Board as their first step into the ARM single board computer world. Earlier this month I finally received a Tinker Board for testing and it has been quite interesting to say the least. The Tinker Board with its Rockchip SoC has been among the most competitive ARM SBCs we have tested to date in its price range and the form factor is compatible with the Raspberry Pi.
CentOS developers Karanbir Singh and Jim Perrin announced the release of the CentOS 7.4 operating system for supported architectures, a release that brings all the latest updates and security patches.
Canonical announced that it partnered with NEC Display Solutions Europe to collaborate on a new digital signage platform powered by the Ubuntu Core operating system for embedded and IoT devices.
Two months ago, Linux 4.12 was released with initial support for AMD Radeon RX Vega GPU, BFQ (Budget Fair Queuing) and Kyber block I/O schedulers, AnalyzeBoot tool for the kernel, “hybrid consistency model” implementation for live kernel patching, but disabled the Open Sound System, and removed AVR32 support, among many other changes.
I recently bought a new Raspberry Pi 3 and installed Slackware ARM current (hard float) on it. My goal was to compare the performance of the hard float port against Slackware ARM 14.2 (soft float), which is currently powering this RPi3 hosted website.
What is the best way to save power consumption of your embedded Linux system? Is there any way to save max power and resume operation ? Yes. It is ‘hibernate’ mode, one of the Power Modes in Linux. This article talks about how we utilized this ‘hibernate mode’ in our Reference Platform Kit Meissa-I with eSOMiMX6-micro SOM.
As of Wednesday, August 16, 2017, the Raspberry Pi Foundation has released new installation images of its Debian-based Raspbian Linux operating system rebased on Debian GNU/Linux 9 "Stretch" series.
The decision to use device tree in Linux occurred several years ago, after Linus Torvalds complained that Linux on ARM was a mess, with the ultimate goal of providing a unified ARM kernel for all hardware.
After announcing the latest build of his Ubuntu-based RaspEX Linux distro for Raspberry Pi 3 and 2 SBCs, GNU/Linux developer Arne Exton now informs Softpedia about the release of RaspAnd Nougat 7.1.2 Build 170805.
GNU/Linux developer Arne Exton on Thursday announced the release and general availability of a new stable build of his Ubuntu-based RaspEX Linux operating system for Raspberry Pi 3 and 2 single-board computers.
Canonical on Wednesday announced that the Ubuntu Kernel Team had started work on a Linux 4.12-based kernel for the Raspberry Pi 2 variant of the upcoming Ubuntu 17.10 (Artful Aardvark) operating system.
