ESP32-C3 AWS IoT ExpressLink module & devkit aim to ease connection to AWS IoT services

Amazon and Espressif have launched another wireless module with the ESP32-C3 AWS IoT ExpressLink module together with a development kit supporting out-of-the-box AWS IoT connectivity, following their earlier collaboration with the launch of the ESP32-PICO-V3-ZERO Alexa Connect Kit Module last summer. Also called the “ESP32-C3-MINI-1-N4-A”, the ESP32-C3 AWS IoT ExpressLink module implements the AWS IoT ExpressLink specification and provides AWS IoT Core connectivity to a host MCU via AT commands over a UART interface. Pre-provisioned and pre-programmed with ease integration the module supports WiFi configuration, messaging, OTA, and device management. The compact (16.6 x 13.2mm) ESP32-C3 module is currently offered as part of the ESP32-C3-AWS-ExpressLink-DevKit development board following the Arduino Zero board form factor allowing it to be plugged into the Arduino board, or easily connect to other host systems such as the Raspberry Pi. The goal is to simplify the deployment of IoT solutions removing the need for […]

SiFive Performance P650 RISC-V core to outperform Arm Cortex-A77 performance per mm2

About six months have passed since the SiFive announcement of the Performance P550 “fastest 64-bit RISC-V processor” ever, and the company has now introduced an even faster RISC-V core with the Performance P650 that’s expected to match Cortex-A77 performance. Building upon the Performance P550 design, the SiFive Performance P650 is scalable to sixteen cores using a coherent multicore complex, and delivers a 40% performance increase per clock cycle based on SiFive engineering estimated performance in SPECInt2006/GHz, thanks to an expansion of the processor’s instruction-issue width. The company compares P650 to the Arm family by saying it “maintains a significant performance-per-area advantage compared to the Arm Cortex-A77”. SiFive Performance P650 key features: 64-bit RISC-V (RV64GCB) core Sv39/Sv48 Virtual Memory Support Multi-core, multi-cluster processor configurations with up to 16 cores Performance > 11 SpecINT2006/GHz Thirteen stage, four-issue, out-of-order pipeline tuned for scalable performance Private L2 Caches and Streaming Prefetcher for improved memory […]

Tribulations with Linux on Zidoo M6 Rockchip RK3566 mini PC

After our review of the Zidoo M6 mini PC with Android 11, we’ve installed Linux on the Rockchip device, and we did boot to a Linux Qt user interface built with buildroot. Let’s try to see what we can do with the image, and then try Ubuntu from a competing mini PC to check out if that can work. Since there’s no package manager to install a screenshooting program, I tried to use the usual method to take a framebuffer screenshot.

cat /dev/fb0 > screen.raw

1	cat /dev/fb0 > screen.raw

It generated an 8MB file which looked good, but the content was just comprised of zeros.

I asked Zidoo for a method to take screenshots in their Linux image, but I was told there weren’t any at this time… No worries, let’s try some of the applications in the Qt interface starting with the Multivideoplayer: It starts well with 9 videos of Big Buck Bunny playing simultaneously, […]
