NXP i.MX 91 single-core Cortex-A55 SoC to power Linux-based cost-optimized edge devices


NXP has just unveiled the NXP i.MX 91 single-core Cortex-A55 processor following the introduction of the i.MX 93 in 2021, and designed for cost-optimized edge devices running Linux. The NXP i.MX 93 processor comes with up to two Cortex-A55 cores, a Cortex-M33 real-time core, and an Ethos U65 microNPU, but targeting entry-level Linux systems, the NXP i.MX 91 processor does without the real-time core and the AI acceleration, while still integrating NXP EdgeLock Secure Enclave, and the company highlights support for multiple wireless connectivity options through companion chips such as the IW612 that supports Wi-Fi 6, Bluetooth 5.2, 802.15.4, and the new Matter protocol. NXP i.MX 91 specifications: CPU – Arm Cortex-A55 running at up to 1.4GHz with 256KB L2 cache System Memory – Up to 2.4GT/s x16 LPDDR4 with Inline ECC Storage 3x SD 3.0, SDIO 3.0, eMMC 5.1 1x Octal SPI including support for SPI NOR and SPI […]

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 […]

NXP IW612 Wi-Fi 6, Bluetooth 5.2, 802.15.4 tri-radio solution supports Matter

NXP IW612 block diagram

Matter, previously known as Project Chip, is a unified interface for Smart Home devices to improve interoperability between devices from different manufacturers and associated services like Google Assitant or Amazon Alexa. Matter can work over Thread, WiFi, Ethernet, BLE, etc… so it’s not limited by the physical layer. So far, we mostly heard about development related to Matter, and Espressif has published a series of posts about Matter to be for instance used by their upcoming ESP32-H2 wireless MCU, but I had not seen many other solutions, not commercial products. This is going to change in 2022, as Belkin announced it’s working on “redesigned smart plugs and lighting solutions” with support for Matter over Thread” that start selling this summer. Separately, NXP also announced the IW612 tri-radio solution with Matter support and dual-band WiFI 6, Bluetooth 5.2, and 802.15.4 radios. NXP IW612 IW612 key features and specifications: Dedicated, independent CPUs […]
