Embedded Linux Conference & Open Source Summit 2019 Schedule

In the last few years, I covered the Embedded Linux Conference and IoT Summit schedules since both were happening at the same time and in the same location. But the Linux Foundation have recently announced the Embedded Linux Conference will combine with the Open Source Summit, so the IoT Summit appears to have been phased out. The full schedule for the events taking place on August 21 – 23, 2019 at the Hilton San Diego Bayfront, USA, has also been released, so I’ll create a virtual schedule with some of the sessions most relevant to this blog. Wednesday August 21, 2019 11:30 – 12:05 – What’s New with U-Boot? by Simon Glass, Google LLC U-Boot is a widely used bootloader in embedded systems. Many users are unaware of the wide feature-set of U-Boot, particularly features added in the last few years. This talk aims to bring users (and prospective users) […]

MBCFET Process Technology to Enable 3nm Chips in 2021

We often read new processor are manufactured with a FinFET process. The new process was created due to short channel effects in traditional planar transistors, and FinFET (Fin Field-effect transistor) was introduced to enable further voltage scaling but with the process node becoming smaller and smaller, electrostatics effects started to cause problem. A solution was to use GAA (Gate All Around) nanowires to limit those effects, but those are apparently really hard to integrate into silicon, so Samsung ended up using thin layers (nanosheets) instead of nanowires enabling greater current per track in their GAA implementation called MBCFET (Multi-Bridge Channel Field-Effect Transistor). While FinFET starts to encounter limitations under 4-5nm, MBCFET will enable manufacturing of chips using a 3nm process. Silicon designers can get started straight away as Samsung Foundry has recently announced the release of their 3GAE PDK (Process Design) version 0.1. Compared to 7nm FinFET technology, Samsung’s 3GAE […]

Programmable-Air is an Arduino Nano Powered Pneumatics Kit (Crowdfunding)

Programmable-Air Arduino Nano Pneumatics Kit

Programmable-Air is a hardware toolkit that allows you to inflate and deflate objects. Powered by an Arduino Nano board, the kit comes with high pressure and vacuum pumps, valves, and a pressure sensor that enables users to experiement and learn about pneumatics and inflatables. Some of the potential applications include vacuum pick and place machines, soft robots able to walk, soft robotics hands, using a syringe as a linear actuator, inflatable bras, arts projects and more. Programmable-Air specifications: MCU Board – Arduino Nano board based on Microchip ATMega328P microcontroller Pneumatics – Full channel control, i.e. high pressure through atmospheric pressure to vacuum output in the same tube. Max pressure – 0.5 atmosphere (7.5 PSI / 50 kPa) Min Pressure – -0.5 atmosphere (-7.5 PSI / -50 kPa) Flow rate: 2 liters per minute per motor Expansion Grove I²C connector to easily add sensors (Not shown in prototype photo above) Expandable […]

Raspberry Pi based Hyper Keyboard Pi & hgTerm Handheld PCs, and RasPi Arcade Stick

hgterm DIY Raspberry Pi Handheld Computer

There are so many products and projects based on Raspberry Pi that it’s difficult to keep track, and many are often not that interesting, not because they are not useful, but instead because it just feels we’ve seen those before. But this week I’ve come accross three projects that looks to be newsworthy including two handheld computers with a 4″ display, and one retro-gaming console with standard arcade buttons and controls similar to what is found in Pandora’s Box/Key 5S. hgTerm DIY Raspberry Pi Handheld Computer hgterm is a portable computer based on a stripped down Raspberry Pi 3 where the Ethernet port, HDMI port, and most of the USB ports have been removed. It features a 4″ touchscreen display, a Bluetooth keyboard all housed in a 3D printed case. It’s not actually a product that you can buy (yet), but a project made by Igor Brkić which you can […]

Fusion for TIVA v8 Development Board Enables Debugging & Programming over WiFi

Texas Instruments TIVA Arm Cortex-M4 MCU family was first introduced in 2013, I tested a TIVA Launchpad the following years, and since microcontrollers have usually a long life span they are still in use today, and should still be available for many years. I’m writing about this TI MCU family today because MikroElektronika has just announced Fusion for TIVA V8 development board for TI TIVA, Stellaris and MSP432 microcontrollers with plenty of I/Os including some MikroBus expansion slots, as well as support for debugging and programming over WiFi in addition to the usual USB-UART interface. Fusion for TIVA v8 board specifications: MCU – Socket for MikroElektronika MCU CARD Display Interfaces 2x 20-pin TFT display connector 1x 16-pin LCD connector for 2×16 characters LCD displays in 4-bit mode, optional PWM backlight driving feature Programming – On-board CODEGRIP programmer/debugger, JTAG connector for connecting an external programmer/debugger Connectivity – Ethernet port, WiFI in […]

One Mix 3 Yoga 8.4″ Mini Laptop is up for Pre-order for $760

In recent years we’ve seen several companies launch “mini laptops” with small 6″ to 7″ displays. They have the advantages of being really compact and lightweight, and thanks to Intel Gemini Lake & Amber Lake processors can be fairly powerful. The problem is that with small displays come small keyboards, and people have had a hard type typing text on those. So we’ve started seeing announcements for mini laptops with 8″ to 8.9″ displays such as GPD Pocket 2 Max and CHUWI minibook that should make like easier at the cost of a slightly larger and heavier devices. One Mix 3 Yoga appears to be one the first of those ultra mobile PCs for sale, or more exactly pre-order. You’ll find the pocket laptop on GeekBuying for $759.99 with shipping scheduled for next month. One Netbook One Mix 3 Yoga specifications: SoC – Intel Core m3-8100Y dual-core/quad-thread Amber Lake processor […]

Blueendless X3 Networked “HDD NAS Case” Runs Ubuntu on Marvell ARMADA 3720 SoC

We’ve previously covered inexpensive Kimax’ Ethernet & WiFi HDD enclosures for 2.5″ SATA drives, powered by MediaTek processor and running OpenWrt. If you need something more powerful and versatile yet still affordable, the easiest way is now likely to go with SBC based solutions such as ODROID-HC1/HC2 or dual SATA NAS enclosure for RockPro64. There may be another interesting option, as I’ve just been informed about another model of those networked HDD enclosure called Blueendless X3 “HDD NAS case” with Ethernet only (no WiFi), and that is equipped with the same Marvel ARMADA 3720 dual core Cortex-A53 processor as found in Marvell ESPRESSOBin board. Blueendless X3 specifications: SoC – Marvell ARMADA 3720 (88F3720) dual core Cortex-A53 processor @ up to 1.1 GHz System Memory – 512 MB DDR3 Storage – 16GB eMMC flash for OS, SATA 3.0 interface for 2.5″ drives based on ASMedia ASM1092R port multiplier Networking – 1x […]

More Intel Processor HW Security Flaws. Meet Microarchitectural Data Sampling (MDS)

2018 did not start so well for processor vendors, especially Intel, but also AMD, Arm and others as some of their processors leveraging speculative execution were impacted by Spectre and/or Meltdown hardware security bugs. The workarounds to improve security had a downside as they affected performance in some specific use case. Panic ensued as the bug was revealed to the public a bit too early, so companies were not fully ready with their mitigations / workarounds. Then in summer of 2018, another hardware security flaw known as Foreshadow or L1 Terminal Fault came to light. The new flaw potentially enabled the attacker to access data stored in L1 cache. Provided you have updated your operating systems to the latest version, your computers and devices should be protected against those vulnerabilities, and you can even check with a script working in Linux or FreeBSD. But this now looks like a never […]
