Linux 4.8 Release – Main Changes, ARM & MIPS Architectures

Linus Torvalds has officially released Linux 4.8 last Sunday: So the last week was really quiet, which maybe means that I could probably just have skipped rc8 after all. Oh well, no real harm done. This obviously means that the merge window for 4.9 is open, and I appreciate the people who already sent in some pull requests early due to upcoming travel or other reasons. I’ll start pulling things tomorrow, and have even the most eager developers and testers hopefully test the final 4.8 release before the next development kernels start coming 😉 Anyway, there’s a few stragging fixes since rc8 listed below: it’s a mixture of arch fixes (arm, mips, sparc, x86), drivers (networking, nvdimm, gpu) and generic code (some core networking, with a few filesystem, cgroup and and vm things). All of it pretty small, and there really aren’t that many of them. Go forth and test, […]

Review of Allo Vana Player Linux HiFi Audio System with Max2Play, SqueezeBox and Kodi

Last month I showcased what I called “Allo Sparky Audio Kit” with a DAC board (Piano), an amplifier board (Volt), and usually hard to find  reclocker and capacitance multiplier boards (Kali & CM), all connected to Allo Sparky ARM Linux development board powered by Actions Semi S500 quad core Cortex A9 processor, and running Ubuntu 12.04. In the first post, I just described the boards, and showed how to assemble the kit, but now that I have received the user’s manual, it turns out the kit is actually called “Vana Player” and the provided Ubuntu firmware image runs Max2Play Browser based system that’s also available for Raspberry Pi and ODROID boards. Before starting the kit, you’ll need to connect speakers to Piano DAC board and/or Kali board, as well as a 19.5V power source such as a laptop power supply to connect to the CM board. I connected some USB […]

Android 7.0, Android TV 7.0, and Yocto Project Ported to Pine A64 Boards

A few weeks ago, Raspberry Pi 3 got an Android 7.0 Nougat port, and it’s usable for some app even simple games like Angry Bird, but there are still problems with 3D graphics, and hardware video decoding. But thanks to Pine64 forum’s member Ayufan, we now have Android 7.0 and Android TV 7.0 for Pine A64 boards with 1GB or more memory with 3D graphics, and hardware video acceleration for most apps. Everything is said to pretty much work, but there are some known issues, such as camera support (being worked on now), touchscreen support (not tested), YouTube is limited to 360p/480p as it does not support hardware video decoding, and Widevine DRM is not supported. Android 7.0 has also been shown to be about 10 to 15% faster than Android 5.1.1 in GeekBench. Ronnie Bailey has shot a video showing Pine A64 running Android TV 7.0 Nougat. If you […]

Nextcloud Box is a $80 Private Cloud Server with 1TB HDD for Development Boards

While there are plenty of cloud services provided by companies such as Dropbox or Google, you may want to manage you own private cloud server instead for performance and/or privacy reasons. One typical way to do this is to install Owncloud or Nextcloud (a fork of Owncloud), on a Linux computer or board such as Raspberry Pi 3. The former is usually a little expensive for just this task, the latter often results in cable mess, and in both case, some people may not be comfortable with setting it all up. Nextcloud, Western Digital, and Canonical seems to have addressed most of those issues with Nextcloud Box including a 1TB USB 3.0 WDLabs harddrive, Nextcloud case with space for the drive and small ARM or x86 Linux development boards, and a micro USB power supply. The kit also include a micro SD card pre-loaded with Snappy Ubuntu Core, Apache, MySQL […]

SZTomato TVI Amlogic S905X Development Board to Support Android 6.0, OpenELEC 7.0, and Ubuntu 16.04

Shenzhen Tomato has been selling Android TV boxes for a few years now, but one of their next product will be a development board based on Amlogic S905X processor with 8GB flash, 2GB RAM, and the usual 40-pin Raspberry Pi header. SZTomato TVI development board specifications: SoC –  Amlogic S905X quad core ARM Cortex-A53 @ up to 2.0GHz with penta-core Mali-450MP GPU @ 750 MHz System Memory – 2GB DDR3 (1GB or less as option) Storage – 8GB Samsung eMMC flash (other capacities as option)  + micro SD slot Video & Audio  Output – HDMI 2.0a up to 4K @ 60 Hz Connectivity – Fast Ethernet port, 802.11 b/g/n WiFi and Bluetooth 4.0 (Ampak AP6212) with IPEX connector USB – 2x USB 2.0 host ports with 500mA fuses, 1x USB type C port for power and USB devices (no video) Expansion header – 40-pin Raspberry Pi compatible header with USB, […]

Project OWL Open Source Hardware Ophthalmoscope is 25 Times Cheaper than Commercial Products

Medical grade equipments are usually very expensive, partly because of their complexity, but also because of certifications,   legal reasons, and low manufacturing volumes. That’s where open source hardware can make a big difference, and there has been several open source hardware prosthetic hands or arms such as Openbionics hand, but Ebin Philip and his team has tackled another issue with Project OWL, an open indirect ophthalmoscope (OIO) designed for screening retinal diseases, which normally costs between $10,000 to $25,000, but their open source hardware design can be put together for about $400. The design features a Raspberry Pi 2 board connected to a WaveShare 5″ Touchscreen LCD, a Raspberry Pi Pi IR Camera (M12 lens mount) with 16mm FL M12 lens, a 3 Watt Luxeon LED, two 50x50mm mirrors, a linear polarizer sheet, a 20 Dioptre disposable lens, and various passive components. While the Raspberry Pi board is not open […]

U-Boot Now Supports UEFI on 32-bit and 64-bit ARM Platforms

Intel/AMD x86 based computers now boot via a standard UEFI binary, which can load grub2, allows you to update the command line as needed, or select different version of the Linux kernel. On ARM everything is a little more complicated and messy, as bootloaders such as U-boot need to support different configurations formats. Alexander Graf has been working on implementing UEFI support in U-boot, and it’s now supported by U-boot mainline and enabled by default for 32-bit and 64-bit ARM platforms, but not x86-64 (yet). That means you should now be able to boot any ARM boards supported by mainline U-boot through UEFI. Alexander gave a presentation about his work at an openSUSE event in June, and demonstrated u-boot with UEFI, and GRUB2 support with an openSUSE image running on a Raspberry Pi board. Thanks to David for the tip. Jean-Luc Aufranc (CNXSoft)Jean-Luc started CNX Software in 2010 as a […]

Samsung JerryScript is a Lightweight Open Source JavaScript Engine for the Internet of Things

In the old days, micro-controller programming was all done in assembly or C, but in recent years higher level languages, included interpreted ones such as Python and JavaScript, have made their ways into MCUs with projects such as MicroPython or Espruino (JS) often running on STMicro STM32 ARM Cortex M micro-controllers, but also other platforms such as ESP8266. As I browsed through the Embedded Linux Conference Europe 2016 schedule, I discovered that Samsung worked on it own implementation of a JavaScript engine for the Internet of Things: JerryScript. It is a full implementation of ECMAScript 5.1 standard written in C that can run on micro-controllers with less than 64KB RAM, and less than 200KB storage (160KB footprint with ARM Thumb-2 compilation). JerryScript is comprised of two main components: Parser and Virtual Machine (VM), with the parser performing translation of input ECMAScript application into byte-code than is then executed by the Virtual […]
