Windows Subsystem for Linux 2 Gets a Linux Kernel, Faster File System, Docker Support

Microsoft first introduced Windows Subsystem for Linux in 2016 in order to let developers runs bash command from Ubuntu user space without having to install Ubuntu in a virtual machine or container. It relies on the Windows kernel with a library converting Linux system calls into ones compatible with Windows. Performance is great until you start to involve file systems calls, for example during code compilations, something that’s fairly common for developers… Microsoft has been working on solving this performance issue, and compatibility issues with software such as Docker, and is now close to releasing Windows Subsystem for Linux 2 (WSL 2) featuring its own Linux 4.19 kernel instead of the Windows kernel plus a translation layer. WSL 2 uses virtualization technology to run its custom Linux kernel inside of a lightweight utility virtual machine (VM) which takes just 2 seconds to boot. That also means there will be separate […]

miriac MPX-LS1028A NXP QorIQ LS1028A SoM Targets TSN Applications with HMI Display

NXP QorIQ LayerScape LS1028A communication SoC was first unveiled in March 2017 with two Armv8 cores, GPU and LCD controller for HMI systems, as well as Time-Sensitive Networking (TSN) capabilities useful in industrial settings. As usual it takes a while before the company finalize their design and software support, but LS1028A has started to appear at least in one hardware platform that’s supposed to launch this quarter (Q2 2019): MicroSys miriac MPX-LS1028A system-on-module. miriac MPX-LS1028A SoM specifications: SoC – NXP QorIQ LS1018 / LS1028 single / dual core Arm Cortex-A72 clocked at up to 1.3 GHz with MXC Vivante GPU, Mali Display Processor, configurable cryptographic offload engines (Optional: LS1017/LS1027 without GPU for cost saving) System Memory – Up to 4GB 32 Bit DDR4 with ECC RAM at up to 1600 MT/s Storage – Up to 256MB Serial NOR Flash & up to 4GB Serial NAND Flash; EEPROM MXM 2.0 edge […]

Linux 5.1 Release – Main Changes, Arm, MIPS & RISC-V Architectures

Linus Torvalds has just announced the release of Linux 5.1: So it’s a bit later in the day than I usually do this, just because I was waffling about the release. Partly because I got some small pull requests today, but mostly just because I wasn’t looking forward to the timing of this upcoming 5.2 merge window. But the last-minute pull requests really weren’t big enough to justify delaying things over, and hopefully the merge window timing won’t be all that painful either. I just happen to have the college graduation of my oldest happen right smack dab in the middle of the upcoming merge window, so I might be effectively offline for a few days there. If worst comes to worst, I’ll extend it to make it all work, but I don’t think it will be needed. Anyway, on to 5.1 itself. The past week has been pretty calm, […]

Pinebook Pro Arm Laptop Video Demo

Pine64 first revealed working on Pinebook Pro Arm Linux laptop at FOSDEM 2019 back at the end of January. The first Pinebook laptop had limited hardware resources, and as such was meant for simple tasks, but Pinebook Pro equipped with Rockchip RK3399 processor, 4GB RAM, 64GB to 128GB flash, and a 14″ Full HD display is designed to be used as your main laptop. That means everything needs to work from 3D graphics acceleration, to hardware video decoding, and USB-C video output. Lukasz Erecinski very recently shot a demo of the laptop in action, and everything looks very good, meaning the laptop should be come available soon. You can watch the demo further below, but if you are in a rush here’s what has been tested and works: Ubuntu & Debian with MATE desktop 4K video playback 3D graphics acceleration for games (Quake demo) 3D graphics acceleration in Chromium web […]

Enabling Two-Factor Authentication for SSH Access in Armbian

Until today, I only knew of two authentication methods for SSH: the traditional username/password and key-based login with private/public keys with the latter being more secure and not requiring any password. But I’ve just found out it’s also possible to login to SSH using two-factor authentication relying on your smartphone to get an OTP code like you would to access some banking services as it can easily be enabled in Armbian. First you’ll want to enable key-based login with private/public keys, or you won’t be able to access your board anymore after enabling 2FA except via the serial console. Now simply start armbian-config, and go to System Settings->Reconfigure SSH daemon to enable PhoneAuthentication “mobile phone one-time passcode”. We’re not done yet, so don’t close Armbian-config You’d then need an Android or iOS phone running Google Authenticator app to receive the OTP (one-time password). After enabling PhoneAuthenticator in armbian-config, you’ll see […]

Toradex Torizon Industrial Linux Distribution Targets Windows Developers

When we interviewed Toradex right before Embedded World 2019, they told us they would focus on their new software offering called Torizon, an easy-to-use industrial Linux Platform, especially targeting customers are coming from the Windows / WinCE environment or who have only experience with application development and are not embedded Linux specialists. The company has now officially launched Torizon, and provided more details about their industrial open source software solution especially optimized for their NXP i.MX modules. Torizon specifically relies on foundries.io Linux microPlatform which provides full system with a recent stable kernel, a minimal base system built with OpenEmbedded/Yocto, and a runtime to deploy applications and services in Docker containers. The microPlatform is part of TorizonCore (light blue section above) that also includes an OTA client (Aktualizr). TorizonCore is free open-source software, and serves as the base to run software containers. To get started, Torizon provides a Debian container […]

Semtech Releases Open Source Software for LoRa Gateways & Devices

Semtech has released open source software for LoRa-based gateways including LoRa Basic Station packet forwarder for Linux-based gateways, LoRa Basic MAC implementation of the LoRa Alliance’s LoRaWAN specification, and LoRa Basic loader bootloader capable of handling firmware updates. All three components are available for free under a revised 3-Clause BSD license. LoRa Basic Station supports LoRaWAN Classes A, B, and C, presents a unified radio abstraction layer supporting Concentrator Reference Designs v1.5 and v2, and implements various backend protocols. Apart from mbedTLS and libloragw/-v2, it does not rely on external dependencies, the code is written in C language only, and easily portable to Linux gateways and embedded systems. LoRa Basic MAC is a fork of IBM’s LMiC library, also implemented in C language, supports multiple regions selectable at compile and/or run time, and can handle Class A, Class B, and Class C devices. Basic MAC uses LoRa Basic loader to […]
