Linux 5.6 Release – Main Changes, Arm, MIPS & RISC-V Architectures

Linus Torvalds has just announced the release of Linux 5.6 on the Linux Kernel Mailing List: So I’ll admit to vacillating between doing this 5.6 release and doing another -rc. This has a bit more changes than I’d like, but they are mostly from davem’s networking fixes pulls, and David feels comfy with them. And I looked over the diff, and none of it looks scary. It’s just slightly more than I’d have preferred at this stage – not doesn’t really seem worth delaying a release over. So about half the diff from the final week is network driver fixlets, and some minor core networking fixes. Another 20% is tooling – mostly bpf and netfilter selftests (but also some perf work). The rest is “misc” – mostly random drivers (gpio, rdma, input) and DTS files. With a smattering of fixes elsewhere (a couple of afs fixes, some vm fixes, etc). […]

Seeed IoT Button for AWS Brings Back Amazon Dash Button to Life for Developers

Amazon introduced $5 dash buttons in 2015 to let consumers purchase regular items such as washing powder by simply pressing a button. Some people hacked them for other purposes, for instance as WiFi logging buttons, but the company eventually stopped selling the buttons in February 2019 and fully killed those at the end of August. Seeed Studio is bringing back Amazon Dash button to life in some ways, with the Seeed IoT Button For AWS Wi-Fi-based, programmable button that deploys the AWS IoT 1-Click service. Seeed IoT Button for AWS hardware specifications: MCU – Dual-core MCU with 20MHz Cortex M0 and 200MHz Cortex M4F (Very likely Realtek RTL8720DN Wireless MCU) Storage – 4MB flash Connectivity – Dual-band Wi-Fi 4 802.11 a/b/g/n (2.4GHz & 5GHz) and Bluetooth 5.0 LE USB – 1x USB Type-C port for charging Misc – Button good for 100,000 cycles, 3x LEDs (red, green, blue) Power Supply […]

Project Connected Home over IP (CHIP) Working Group is Backed by Google, Apple, Amazon, and the Zigbee Alliance

Amazon, Apple, Google, and Zigbee Alliance have partnered to create Project Connected Home over IP (CHIP) working group aiming to develop a royalty-free, Smart Home standard to increase compatibility among products, and with security at the forefront. The new standard will be separate from Zigbee 3.0 / Pro, and Zigbee Alliance board member companies such IKEA, Legrand, NXP Semiconductors, Resideo, Samsung SmartThings, Schneider Electric, Signify (formerly Philips Lighting), Silicon Labs, Somfy, and Wulian will also join the CHIP working group and contribute to the project. The standard specified by Project Connected Home over IP will rely on existing technology from the networking layer including TCP/UDP transport protocol, IPv6 network and various physical & media standards such as WiFi, Ethernet, Bluetooth LE, Cellular, 802.15.4 and others. Instead, it will define what happens at the application layer level with the following points of focus: End-to-end data security and privacy among in-home and […]

AWS EC2 6th Gen Instances are 7x Faster thanks to Graviton 2 Arm Neoverse N1 Custom Processor

Last year Amazon introduced their first 64-bit Arm-based ECS2 “A1” instances which were found to deliver up to 45% cost savings over x86 Instances for the right workloads. A few months ago, AWS (Amazon Web Services) provides a new offering with bare-metal A1 instances, and with re:invent 2019 now taking place the company has unveiled AWS ECS2 6th generation Arm instances (which they did not call A2 instances yet) powered by Graviton 2 processor comprised of custom Arm Neoverse N1 cores and promising up to 7x the performance of the original A1 instances. There will be three types of Graviton2-powered EC2 instances with the d suffix indicating NVMe local storage: M6g and M6gd for General Purpose workloads (application servers, mid-size data stores, microservices, and cluster computing) with 1 to 64 vCPUs and up to 256 GB of memory. C6g and C6gd for Compute-Optimized workloads (high-performance computing, video encoding, gaming, and […]

FreeRTOS Kernel Now Supports RISC-V Architecture

FreeRTOS is one of the most popular operating systems found in embedded systems, and RISC-V open architecture is getting more and more traction, so it should come as no surprise that Amazon has now added RISC-V to their recently acquired FreeRTOS kernel. Jeff Barr, Chief Evangelist for AWS, explains both 32-bit and 64-bit RISC-V cores are supported, and several RISC-V boards are already supported out of the box: The kernel supports the RISC-V I profile (RV32I and RV64I) and can be extended to support any RISC-V microcontroller. It includes preconfigured examples for the OpenISA VEGAboard, QEMU emulator for SiFive’s HiFive board, and Antmicro’s Renode emulator for the Microchip M2GL025 Creative Board. There’s no a lot of information on Amazon announcement post, but FreeRTOS website has plenty of resources to help you get started with RISC-V. The page also lists some of the key features of the RISC-V port: Supports machine […]

Amazon Echo Look Camera Goes for $50 with Intel Atom x5, RealSense Camera SR300

Amazon Echo Look is a smart camera with Alexa Assistant that was launched about 2 years ago for $200, and designed to help you decide if your outfit is a good match, beside taking photo and video selfies with voice commands. Sales may not have matched Amazon expectations (unsurprisingly), and the product is now offered for just $49.99. What may be interesting for CNX Software readers is that Echo Look appears to be a consumer version of AWS DeepLens deep learning video camera for developers ($249), plus some cost savings as well, so there may be some hacking potential here. A teardown video – embedded below – reveals some interesting specifications: SoC – Intel Atom x5-Z8350 quad core Cherry Trail processor @ up to 1.44 GHz System Memory – 1 GB LPDDR3 Storage – 8GB eMMC flash, 16 Mbit SPI flash Camera – Intel RealSense SR300 depth sensing camera + […]
