Snagboot is an open-source cross-vendor recovery tool for embedded targets

Bootlin has just released the Snagboot open-source recovery tool for embedded platforms designed to work with multiple vendors, and currently STMicro STM32MP1, Microchip SAMA5, NXP i.MX6/7/8, Texas Instruments AM335x and AM62x, and Allwinner “sunxi” processors are supported. Silicon vendors usually provide firmware flashing tools, some closed-source binaries, that only work with their hardware. So if you work on STM32MP1 you’d use STM32CubeProgrammer, while SAM-BA is the tool for Microchip processors, NXP i.MX SoC relies on UUU, and if you’ve ever worked on Allwinner processors you’re probably family with sunxi-fel. Bootlin aims to replace all those with the Snagboot recovery tool. The Python tool is comprised of two parts: snagrecover using vendor-specific ROM code mechanisms to initialize external RAM and run the bootloader (typically U-Boot) without modifying any non-volatile memories. snagflash communicates with the bootloader over USB to flash system images to non-volatile memories, using either DFU, USB Mass Storage, or […]

STMicro unveils STM32MP2 Arm Cortex-A35/M33 MPU family starting with STM32MP25

STMicro has introduced its second generation of its STM32 MPUs (microprocessors) with the STM32MP2 moving to a 64-bit Arm architecture with Edge AI acceleration, multimedia features, graphics processing, and digital connectivity targeting industrial and IoT edge applications. The new family follows the STM32MP1 Arm Cortex-A7/M4 series introduced in 2019, and the first member of the family is the STM32MP25 with up to two 1.5 GHz Cortex-A35 cores coupled with an Arm Cortex-M33 real-time core clocked at 400 MHz, a 3D GPU, and a 1.35 TOPS NPU for AI acceleration. STM32MP25 key features and specifications: CPU – Single or dual Arm Cortex-A35 cores running up to 1.5 GHz Real-time MCU – Arm Cortex-M33 core running up to 400 MHz GPU – Unnamed 3D GPU for “advanced HMI” with support for the Vulkan API VPU – H.264 hardware video decoder and encoder AI accelerator – 1.35 TOPS NPU (Neural processing unit) System […]

HARDWARIO CHESTER – A configurable Zephyr OS LPWAN IoT gateway with LoRaWAN, LTE IoT, GNSS connectivity

HARDWARIO CHESTER platform is a configurable LPWAN IoT gateway whose main function is to connect as many devices and environments as possible to the Internet using connectivity such as LoRaWAN, LTE Cat M1, or NB-IoT, as well as GNSS for geolocation. Contrary to most IoT gateways, it does not run Linux on an application processor, and instead, the “brain” of the CHESTER IoT gateway is a Raytac Bluetooth 5.0 module based on a Nordic Semi nRF52840 Arm Cortex-M4 microcontroller running Zephyr real-time operating system, which connects to LTE IoT modem and a LoRaWAN module through UART, and expansion modules through I2C, 1-wire, and GPIO interfaces. HARDWARIO CHESTER specifications: Wireless modules/chips Raytac MDBT50Q-P1MV2 Bluetooth 5.0 module based on Nordic Semi nRF52840 Arm Cortex-M4F MCU with 1MB Flash memory, 256kB RAM Nordic Semi nRF9160-SICA-B1A-R7 LTE-M/NB-IoT system-in-package (SiP) with Arm Cortex-M33 MCU, 1024 KB flash, 256 KB SRAM Murata CMWX1ZZABZ-078 LoRa module as […]

EVerest is an open-source software stack for car charging stations

EVerest open source car charging station software

EVerest is a software project initiated by PIONIX GmbH, but now part of the Linux Foundation’s LFEnergy initiative, whose primary goal is to develop and maintain an open-source software stack for EV charging infrastructure. EVerest supports multiple standards and it will run on any device from AC home chargers to public DC charging stations. I noticed the EVerest project in an upcoming talk at the Embedded Open Source Summit 2023 entitled ” EVerest: Electric Vehicle Chargers With Open Hardware and Software” and whose abstract reads in part: You will learn how to build your own electric vehicle charger using open hardware designs in combination with the EVerest open-source software stack for EV charging infrastructure. Following a quick introduction to EV charging technology, with explanations of the standards, protocols, and complexities involved, the talk will go into a deep dive into how you can build your own AC charging station.

STMicro introduces cost-optimized STM32MP13 Cortex-A7 microprocessor

STMicroelectronics’ STM32MP13 1 GHz single-core Arm Cortex-A7 microprocessor series is the latest addition to the Linux-capable STM32MP1 family, with a cost-optimized design that does without the Cortex-M4 real-time core found in the original STM32MP15 series, while still offering Ethernet, CAN FD, camera and display depending on the specific SKU: STM32MP131, STTM32MP133, or STM32MP135. STM32MP131 The STM32MP131 is a single-core Cortex-A7 core clocked at 650 MHz or 1GHz with Ethernet connectivity and is the most cost-effective part of the new STM32MP13 series. Four parts are available in three different packet sizes (TGBGA 289, TFBGA 320, and LFBGA 289) as well as some parts with “advanced security features” that include a cryptographic accelerator, memory protections, code isolation mechanisms for runtime protection, functions to ensure platform authentication, and a complete security ecosystem. The STM32MP131 can run entry-level Linux, bare metal or RTOS systems with Microsoft Azure RTOS pre-integrated. STM32MP133 The STM32MP133 single-core Cortex-A7 […]
