Microsoft open-sources Eclipse ThreadX real-time operating system

Microsoft will soon open-source Eclipse ThreadX real-time operating system that has been deployed on more than 12 billion embedded devices worldwide since its first release in 1997 and, for instance, it is found in Broadcom processors powering Raspberry Pi SBCs. ThreadX was a commercial, safety-certified real-time operating system developed Express Logic which was acquired by Microsoft in 2019 and renamed to Azure RTOS. Last year, Microsoft decided to start the process to fully open-source Azure RTOS under an MIT license and managed by the Eclipse Foundation. Hence its new name: “Eclipse ThreadX“. The Eclipse ThreadX project is not simply comprised of the RTOS itself, but also includes other components: ThreadX – Real-time operating system (RTOS) designed for deeply embedded applications NetX Duo – Industrial-grade TCP/IP network stack designed for deeply embedded real-time and IoT applications FileX – FAT-compatible file system integrated with ThreadX kernel GUIX – Embedded graphical user interface […]

$16 Grove Vision AI V2 module features WiseEye2 HX6538 Arm Cortex-M55 & Ethos-U55 AI microcontroller

Seeed Studio’s Grove Vision AI V2 module is based on the HiMax WiseEye2 HX6538 dual-core Cortex-M55 AI microcontroller with an Arm Ethos-U55 microNPU and features a MIPI CSI connector for an OV5647 camera. It is designed for AI computer vision applications using TensorFlow and PyTorch frameworks and connects to hosts such as Raspberry Pi SBCs, ESP32 IoT boards, Arduino, and other maker boards over I2C. We tested the previous generation Grove Vision AI module based on the 400 MHz HX6537-A DSP-based AI accelerator using the SenseCAP K1100 sensor prototype kit with LoRaWAN connectivity, and managed to have the kit perform face detection and send the data over LoRaWAN. The Grove Vision AI V2 builds on that but with a modern Arm MCU core and more powerful AI accelerator that can run models such as Mobilenet V1/V2, Efficientnet-lite, and Yolo v5 & v8 using the SenseCraft low-code/no-code platform. Grove Vision AI […]

2023 Year in review – Top 10 posts, statistics, and what to expect in 2024

It’s the last day and last article of the year, so we will look at some highlights of 2023, some traffic statistics on the CNX Software website, and speculate what interesting developments may happen in 2024. Looking back at 2023 The semiconductor shortage that had happened since 2020 started to fade away in early 2023, and supplies for most electronics components and devices seem to be adequate at this time, so that was a bright spot this year, and hopefully, it will stay that way in 2024 despite geopolitical tensions. We did not have any super exciting new Arm application processors from Rockchip, Amlogic, or Allwinner announced this year, although the Amlogic S928X penta-core Cortex-A76/A55 CPU started to show up in some 8K TV boxes. The launch of the Raspberry Pi 5 SBC with a Broadcom BCM2712 quad-core Cortex-A76 processor was probably the main highlight for Arm on this side […]

UP 7000 SBC review – Part 2: Ubuntu 22.04 on a fanless Intel N100 single board computer

The UP 7000 is a credit card-sized Alder Lake-N single board computer that can be used as an alternative to the Raspberry Pi 5 for industrial applications. AAEON sent me a model with an Intel Processor N100 CPU, 8GB LPDDR5, and a 64GB eMMC flash, and I went through an unboxing in the first part of the review, compared its mechanical design to the earlier UP 4000 and Raspberry Pi 5 SBC , and also installed Ubuntu 22.04 since the UP 7000 board did not come with any OS and would initially boot to the UEFI shell. I’ve now spent more time with the board and I will report my experience with the UP 7000 SBC running Ubuntu 22.04 in this article checking out features, performance, video playback, power consumption, and so on using the UP 4000 review with Ubuntu 22.04 I did last year as a template plus some […]

International Black Friday and Cyber Monday 2023 deals and coupon codes

We’ve been writing about international Black Friday and Cyber Monday deals and coupon codes since 2014, as US-centric promotions such as Amazon’s Black Friday and Cyber Monday deals are not always available to the international audience of CNX Software. So once again, we’ve searched at Black Friday and Cyber Monday 2023 international promotions and discount codes from specific manufacturers as well as popular online stores such as Aliexpress, Banggood, and others. Aliexpress Black Friday and Cyber Monday event Aliexpress will have a Black Friday (and Cyber Monday) event in 2023, but we have limited details at this time since it will only start on November 23, contrary to some of the other deals we’ll feature below which are already up and running. But the event will have two periods: Nov 20-22 PT – Warm Up event where users can find and add items to the cart before purchasing during the […]

Allwinner Roadmap 2023 2024 automotive industrial SoCs

Allwinner 2023-2024 roadmap reveals A736/A737 Arm Cortex-A78/A76 processors

Allwinner should launch new Cortex-A76/A55 and Cortex-A78/A55 processors in 2024 according to the company’s roadmap including the Allwinner A736/A737 for tablets and the T736/T737 designed for automotive and industrial applications. In recent years, we’ve seen Rockchip and Amlogic introduce more powerful processors with the Rockchip RK3588 octa-core Cortex-A76/A55 processor and Amlogic A311D2 octa-core Cortex-A73/A53 or the more recent Amlogic S928X Cortex-A76/A55 for 8K TV boxes. But we’re still seeing some recent boards based on Allwinner Cortex-A7 32-bit processors, although recently we covered the Allwinner A523 octa-core Cortex-A55 processor for tablets. So today, I decided to go on a quest to find out whether Allwinner plans to use 64-bit Arm “big” cores in their future design. I first ended up on the linux-sunxi website where they list the Allwinner T736 octa-core “sun60i” processor with two Cortex-A76 cores and six Cortex-A55 cores, but no other details. This leads me to some “notes” […]

MistySOM devkit Renesas RZ/G2L or RZ/V2L

MistySoM Renesas RZ/G2L or RZ/V2L SoM and devkit goes for $112 and up

We’ve previously written about several system-on-modules and SBCs based on Renesas RZ/G2L or RZ/V2L Cortex-A55/M33 processors such as Geniatech “AHAURA” RS-G2L100 and “AKITIO” RS-V2L100 single board computers, Forlinx FET-G2LD-C system-on-module, and SolidRun RZ/G2LC SOM and devkit. But most of those are hard to buy, and you need to contact the company, discuss your project, etc… before purchase, except for the SolidRun Renesas RZ/G2LC Evaluation Kit going for $249. Another option is the MistyWest MistySOM module offered for $112 and up on GroupGets with either Renesas RZ/G2L or RZ/V2L processor, as well as an optional carrier board. MistySOM system-on-module MistySOM-G2L (aka MW-G2L) and MistySOM-V2L (aka MW-V2L) specifications: SoC – Renesas RZ/G2L or RZ/V2L with dual-core Cortex-A55 processor @ 1.2 GHz, Arm Cortex-M33 core @ up to 200 MHz, Arm Mali-G31 GPU, and DRP-AI vision accelerator (RZ/V2L only) System Memory – 2GB LPDDR4/DDR4 Storage – 32GB eMMC flash 2x 120-pin high-speed mezzanine […]

Year 2022 in review – Top 10 posts and statistics

It’s the last day of the year and the time to look at some of the highlights of 2022, some traffic statistics from CNX Software website, and speculate on what 2023 may bring us. The semiconductors shortage continued in 2022, but things are looking brighter in 2023 with the full reopening of the world mixed with forecasts of difficult economic times that should keep the demand/supply equation in check. On the Arm processor front the biggest news of the year, at least in this corner of the Internet, was the launch of the Rockchip RK3588 octa-core Cortex-A76/A55 processor together with interesting single board computers that we’ll discuss below. Announced last year, the Amlogic A311D2 octa-core Cortex-A73/A53 was finally made available in a few SBC’s, and we finally got some news about the Amlogic S928X Cortex-A76/A55 SoC showcased in 8K TV boxes, but we have yet to see it in action.
