  • Linux-driven module and starter kit tap Renesas RZ/G2

    TQ’s “TQMaRZG2x” module runs Linux on a dual- to octa-core, Cortex-A57 and -A53 based RZ/G2 processor with up to 8GB LPDDR4 and 64GB eMMC plus an optional dev kit and -40 to 85°C support.

    When reporting on the SMARC 2.0 SoM collaboration between Renesas and RelySys last week featuring Renesas’ scalable, 64-bit RZ/G2 processor, we saw that we missed a September announcement from TQ Embedded about its own RZ/G2 module. The 77 x 50mm TQMaRZG2x is listed as “new” and is available with an optional new Embedded Starterkit STKaRZG2x evaluation board. The module is the first of several Renesas based products from TQ.

  • Mass-Produced, Librem 5 Linux Smartphone Begins Shipping to Customers

    Their announcement notes their work on software making desktop applications "adaptive" to phone form factors, adding "This suite of software has now become the most popular software stack to use on other handheld Linux hardware." And they close with an appreciative comment from Purism's founder and CEO Todd Weaver:

    "Shipping the Librem 5 has been an immense multi-year developmental effort. It is the culmination of people's desire to see an alternative to Android and iOS and fund it, coupled with dedication from a team of experts addressing hardware, kernel, operating system, and applications that has turned a lofty near-impossible goal into reality. We have built a strong foundation and with the continued support of customers, the community, and developers, we will continue to deliver revolutionary products like the Librem 5 running PureOS."

  • Understanding Open Source Hardware

    Open source hardware is “a set of design principles and legal practices, not a specific type of object,” says Opensource.com. Thus, although the term is often associated with electronics, it can apply to other objects as well, including boats, houses, industrial machines, and medical devices.

    The main principles defining open source hardware are similar to those of open source software. The Open Source Hardware (OSHW) Definition 1.0 is in fact “based on the Open Source Definition for Open Source Software, which was created by Bruce Perens and the Debian developers as the Debian Free Software Guidelines.”

  • Evaluating Precursor’s Hardware Security « bunnie's blog

    Hardware security is a multi-faceted problem. First, there is the question of “can I trust this piece of hardware was built correctly?”; specifically, are there implants and back doors buried in the hardware? We refer to this as the “supply chain problem”. It is a particularly challenging problem, given the global nature of our supply chains, with parts pulled from the four corners of the world, passing through hundreds of hands before reaching our doorstep. Precursor addresses this problem head-on with open, verifiable hardware: the keyboard, display, and motherboard are easy to access and visually inspect for correct construction. No factory or third-party tool is ever trusted with secret material. Precursor is capable of generating its own secret keys and sealing them within the hardware, without additional tools.

    We also use a special kind of logic chip for the CPU – an FPGA – configured by the user, not the factory, to be exactly the CPU that the user specified. Crucially, most users have no evidence-based reason to trust that a CPU contains exactly what it claims to contain; few have the inspection capability to verify a chip in a non-destructive manner. On the other hand, with an FPGA, individual users can craft and inspect CPU bitstreams with readily available tools. Furthermore, the design can be modified and upgraded to incorporate countermeasures against hardware exploits discovered in the FPGA’s underlying fabric. In other words, the current trustability situation for an ASIC-style CPU is basically “I surrender”, whereas with an FPGA, users have the power to configure and patch their CPUs.

    [...]

    Once Precursor has been glued shut, we propose the easiest method to recover the ciphertext and to gain access to the JTAG ports is to put the Precursor device into a precision CNC milling machine, mill out the PCB from the back side, and then place the remaining assembly into a pogo-pin based mechanism to perform the readout. This of course destroys the Precursor device in the process, but it is probably the most direct and reliable method of recovering the encryption keys, as it is very similar to an existing technique used for certain types of attacks on iPhones. Storing keys in BBRAM can greatly complicate the task of milling out the PCB by creating a high risk of accidental key erasure, but a sufficiently precise CNC with a non-conductive ceramic bit, or a precision laser-based ablation milling system can reduce the risk of key loss substantially. Cryogenic cooling of the FPGA chip itself may also help to preserve key material in the case of very short accidental power glitches.

  • ASUS unveils Tinker Board 2 SBC with faster Rockchip RK3399 / OP1 processor

    ASUS surprised the maker community in 2017 with the introduction of the Rochchip RK3288 powered Tinker Board to compete as Raspberry Pi 3 Model B. It was followed by Tinker Board S with built-in storage and other new features, as well as Tinker Board Edge T and Edge R SBC’s both with an AI accelerator namely Google Edge TPU and the NPU inside Rockchip RK3399Pro. The company has now launched a new model called Tinker Board 2 without AI accelerator, but featuring Rockchip RK3399, or more exactly the higher grade Rockchip OP1 used in Chromebooks, delivering 96% faster single-thread performance and a 64% boost in multi-core performance compared to the Rockchip RK3288 processor found in the original Tinker Board, while the GPU is around 28% faster with glmark2-es2 off-screen benchmark.

  • Linus Torvalds wants Apple’s new M1-powered Macs to run Linux

    Earlier this month, Apple revealed its own ARM-based M1 processor, along with new MacBooks and a desktop Mac Mini powered by this chip. Reviewers across the globe have been praising Apple‘s first attempt, giving it high marks for performance and battery life.

    All this positive coverage has tempted many to take the plunge and buy one of the new machines — even if some apps are not running natively at the moment. Even Linus Torvalds, the principal developer of the Linux kernel, wants one.

    [...]

    Linux support on MacBooks would’ve made it a more attractive bet for programmers. However, I don’t think any engineers at the Cupertino campus plan to make that happen anytime soon. Sorry, Linus.

ESP32-S3 is expected to be a multi-core WiFI & Bluetooth processor with AI instructions/accelerator, but there were no details about ESP32-C3 at all, and we only found out it would be a RISC-V processor several weeks ago.

  • Raspberry Pi 4 doing domotics

    There does not seem to be any packages for Domoticz. The standard installation method seem to be using an installer shell script. By default, running that script with require root access, to add package dependencies, and will install Domoticz as you current user. I want a dedicated user to run Domoticz ; neither root, nor myself.

    If you need to work on the very latest development version of Android or AOSP, you can either get one of the supported phones such as Google Pixel 5, one of the reference boards for Android which should be better for development and also fairly cheaper. We previously reported about Hikey, Hikey960, and DragonBoard 845c single board computers being part of the short list of reference boards for the Android Open-Source Project (AOSP), but Amlogic powered Khadas VIM3 and VIM3L have recently been added to the official devices page which makes them the first AOSP reference boards with a dedicated NPU / AI accelerator.

  • Arduino Blog » Monitor your heart rate while asleep with ZazHRM

    Have you ever wondered what your heart rate looked like when you were catching some Zs? Or perhaps you would like to check up on how someone nearby is sleeping, without actually disturbing that person. The ZazHRM monitoring system by Alan Do lets you do both, with a pulse sensor hooked up to an Arduino Uno, which in turn sends data to an Android phone in almost real-time via Bluetooth.

    The receiving device runs an MIT App Inventor routine, which can output alarms if the person under observation’s heart rate goes out of range. Results are also logged for later analysis.

  • Arduino Blog » What’s not to love about this realistic beating heart?

    This little motor rotates back and forth under control of an Arduino Uno, making it appear to pulse up and down on a table. One could see this enhanced in a variety of ways, perhaps with a bit of fake blood for an even more lifelike look, or with inputs to the Arduino for interactive capabilities.

    Vue.js is a very powerful, easy to learn, and approachable library that with the knowledge of HTML, CSS, and Javascript, we can start building web applications in it. Vue.js is built by combining the best features from already existing Angular and react Frameworks. It is a progressive and reactive Javascript framework that is used to build UIs (User Interfaces) and SPAs (Single-page Applications), which is why the developers love to code and feel freedom and comfort while developing applications in Vue.js.If we take a look at the Event Listening and Handling in Vue.js., we will know that it provides a “v-on” directive to listen and handle events. We can use the “v-on” directive to listen to the DOM and perform the required tasks. It also provides many event handlers. However, in this article, we will only learn and keep our focus on the click events. So, let’s get started!

Xfce Virtual Machine Images For Development

The openSUSE distributions offer a variety of graphical desktop environments, one of them being the popular and lightweight Xfce. Up to now there was the stable tested branch available in Tumbleweed already during install. Furthermore, for interested users the development OBS repository xfce:next offered a preview state of what’s coming up next to Tumbleweed. Xfce Development in openSUSE Thanks to the hard work of openSUSE’s Xfce team there is a third option: Xfce Development Repository aka RAT In a playful way, a rat is meant to represent the unpolished nature of this release: a rat is scruffy looking compared to a mouse (the cute and beloved mascot of Xfce). And the RAT repository provides packages automatically built right from the Git Master Branch of Xfce upstream development. The goal of this project is to test and preview the new software so that bugs can be spotted and fixed ahead of time by contributing upstream. The packages pull in source code state on a daily basis and offer a quite convenient way to test and eventually help development. So this is where the team builds and tests the latest and unstable releases of Xfce Desktop Environment for openSUSE. Read more

Radeon RX 6800 Series Performance Comes Out Even Faster With Newest Linux Code

Last week we delivered AMD Radeon RX 6800 / RX 6800 XT Linux benchmarks and the performance was great both for Linux gaming as well as the OpenCL compute performance. But for as good as those Big Navi numbers were on the open-source Linux graphics driver stack, they are now even better. That launch-day testing was based on the Linux state in the second-half of October when the cards arrived and initial (re-)testing began in preparing for the Radeon RX 6800 series reviews -- not only the Radeon RX 6800 series but re-testing all of the other AMD Radeon and NVIDIA GeForce graphics cards for the comparison too. Thanks to the rate of the open-source graphics driver progression and the newest code always being available, now just days after launch the numbers are even more compelling for Linux gamers with the slightly newer Linux 5.10 and Mesa Git compared to just weeks ago. In particular were the last minute NGG fixes and other Big Navi tweaks along with an important Radeon RX 6800 (non-XT) fix. There has also been other RADV improvements and more that accumulated in Mesa 21.0-devel this month. On the kernel side, Linux 5.10 is still at play. Both the old and newer Mesa snapshots were also on LLVM 11.0. Read more Also: Intel: AMD Gimps On Battery-Powered Laptop Performance - But DPTF On Linux Still Sucks - Phoronix
