PicoCore MX8MN is a Tiny NXP i.MX 8M Nano Computer-on-Module

The PicoCore MX8MN Nano carries the NXP i.MX 8M Nano F&S Elektronik Systeme has announced the development of the smallest i.MX 8M based CoM yet: the PicoCore MX8MN Nano. Previously we had reported on the Congatec Conga-SMX8 Nano which was a fairly small CoM compliant with SMARC 2.0 standard. The PicoCore MX8MN is based on the NXP i.MX 8M Nano CPU with 1 to 4 Arm Cortex-A53 cores and a Cortex-M7 real-time core. The Nano is set to carry up to 8GB RAM and 32 GB eMMC, with optional WiFI/BT and support for -40º C to 85º C temperature ranges. Similar to Predecessor The PicoCore MX8MN Nano is very similar in structure to the PicoCore MX8MM Mini CoM, but with a different i.MX 8M Mini processor featuring the same Arm Cortex-A53 cores, but the Cortex M4 real-time core is changed to a more powerful Cortex-M7 core in the MX8MN Nano. The MX8MN Nano has no photo on the product page …

Variscite Introduces i.MX 8M Mini and Nano SoM’s, Symphony Carrier Board

NXP i.MX 8M MINI/NANO Development Kit

NXP i.MX 8M Mini and i.MX 8M Nano are lower cost and lower power variants of NXP i.M 8M processors manufactured using a 14nm FinFET process, and cutting some features such as HDMI and embedded DisplayPort, or hardware video decoder. NXP i.MX 8M Mini has been announced for over two years, so we’ve already written about many boards and systems-on-module (SoM) including Boardcon EM-IMX8M-MINI SBC, TechNexion XORE LGA SoM, or Congatec conga-SMX8-Mini SMARC 2.0 module among others. NXP i.MX 8M Nano is more recent, and we only covered a few announcements so far namely iWave Systems iW-RainboW-G34M-SM SoM and Conga-SMX8-Nano SMARC 2.0 computer-on-module. There’s now at least a third company working on a “Nano” module with Variscite announcing VAR-SOM-MX8M-NANO SoM together with a “Mini” version called VAR-SOM-MX8M-MINI, and Symphony carrier board and development kits. VAR-SOM-MX8M-MINI & VAR-SOM-MX8M-NANO Modules Both modules are part of Variscite VAR-SOM Pin2Pin family, and share the following key features & specifications: SoC MINI – NXP i.MX8M …

PineTime Smartwatch Specifications Released, Availability Scheduled for H1 2020

PineTime Charging Cradle & Heart Monitor

A couple of weeks ago, we covered PineTime smartwatch for PinePhone Linux smartphone that should be launched next year for around $25. At the time we had limited information from a Tweet as well as information provided by TL Lim, founder of Pine64 community, such as the watch would be based on Nordic Semi nRF52832 or nRF52840 multi-protocol WiSoC.  But we now have much more details about specs and other details can be found in the Wiki. PineTime specifications: SoC (undecided, one or the other. See differences between nRF52832 and nRF52840 for details) Nordic Semiconductor nRF52832 Arm Cortex-M4F MCU @ 64 MHz with 512KB Flash, 64KB SRAM, Bluetooth 5 (no long range) Nordic Semiconductor nRF52840 Arm Cortex-M4F MCU with 1MB flash, 256KB flash, Bluetooth 5 (long range), 802.15.4 (e.g. for Zigbee), Arm Trustzone, etc… Storage – 8MB SPI NOR Flash (final product may use 16MB flash instead) Display – 1.3″ 240×240 IPS capacitive touchscreen display with 65K colors Connectivity – …

Embedded Linux Conference (ELC) Europe 2019 Schedule – October 28-30

Embedded Linux Conference Europe 2019 Schedule

I may have just written about Linaro Connect San Diego 2019 schedule, but there’s another interesting event that will also take place this fall: the Embedded Linux Conference Europe on  October 28 -30, 2019 in Lyon, France. The full schedule was also published by the Linux Foundation a few days ago, so I’ll create a virtual schedule to see what interesting topics will be addressed during the 3-day event. Monday, October 28 11:30 – 12:05 – Debian and Yocto Project-Based Long-Term Maintenance Approaches for Embedded Products by Kazuhiro Hayashi, Toshiba & Jan Kiszka, Siemens AG In industrial products, 10+ years maintenance is required, including security fixes, reproducible builds, and continuous system updates. Selecting appropriate base systems and tools is necessary for efficient product development. Debian has been applied to industrial products because of its stability, long-term supports, and powerful tools for packages development. The CIP Project, which provides scalable and customizable base image and BSP layers, is now used in …

FreeRTOS Kernel Now Supports RISC-V Architecture

FreeRTOS RISC-V

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 mode integer execution on 32-bit RISC-V cores only, but is …
