Nuvoton NuMicro M3331 Cortex-M33 MCU features built-in ARGB LED controller, optional USB 2.0 OTG interface

Nuvoton's new NuMicro M3331 is a series of 32-bit Arm Cortex-M33 MCUs clocked at 180 MHz that integrate an ARGB LED controller, a DSP instruction set, a single-precision FPU, and TrustZone security for smart factories, renewable energy systems, and consumer devices. In the past, we have written about other Cortex-M33 MCUs like the STM32U3B5/C5, Texas Instruments MSPM33C321A,  Nordic Semi’s nRF54LM20A, and various others, but the Nuvoton M3331 series specifically features a built-in Enhanced LED Light Strip Interface (ELLSI) and up to 10 standard LLSI channels. This allows the MCU to natively support gaming ARGB Gen1 and Gen2 LED control protocols, completely offloading the CPU to run fluid, dynamic LED effects. It comes in two variants, the M3333 series and the M3334 series, with the latter adding a high-speed USB 2.0 OTG controller with an integrated PHY. NuMicro M3331 specifications: MCU core – Arm Cortex-M33 32-bit CPU @ 180 MHz with single-precision

Toradex OSM and Lino SoMs – 30×30mm NXP i.MX 93/i.MX 91 modules with solder-down or B2B connector designs

Toradex has launched two new ultra-compact (30x30mm) System-on-Module (SoM) families: OSM and Lino, powered by NXP i.MX 91 or i.MX 93 Arm Cortex-A55 SoC for Edge industrial and IoT applications. The OSM iMX91 and OSM iMX93 variants comply with the OSM Size-S standard, featuring a 332-ball contact grid designed to be soldered to the carrier board. The Lino is a proprietary format that keeps the OSM Size-S dimensions but features two board-to-board (B2B) connectors offering more flexibility for potential replacement or future upgrades. Toradex Lino iMX91/iMX93 system-on-module Toradex Lino specifications: SoC (one or the other) NXP i.MX 93 CPU 2x Arm Cortex-A55 up to 1.7 GHz 2x Arm Cortex-M33 up to 250 MHz GPU – PXP 2D GPU with blending/composition, resize, and color space conversion NPU – Arm Ethos-U65 NPU @ 1 GHz up to 0.5 TOPS Security – EdgeLock Secure Enclave NXP i.MX 91 CPU - Single-core Arm Cortex-A55

woohoo #zephyros now supports the #trng of the #rp2350 (as found in the rpi pico 2 for example) https://github.com/zephyrproject-rtos/zephyr/pull/83346#event-21872383884
entropy: rpi_pico: implement entropy driver for RP2350 by xudongzheng · Pull Request #83346 · zephyrproject-rtos/zephyr

Use get_rand_64() from Pico SDK for entropy. This is somewhat based on #66764.

#ZephyrOS has a pretty cool http server demo that runs out of the box on many of the supported boards. It can even toggle the LED used in the blinky demo through the browser. It drove my crazy that on my mimxrt1060-evk, the network always lost connection when the LED was toggled. After some unsuccessful debug attempts and #wireshark traces, I finally downloaded the schematics and took a look 🙈

Excellent, hands-on #zephyros workshop in #Gdansk is now behind me!

Spinlock vs. Mutex vs. Semaphore: Разбираемся в синхронизации с Zephyr OS

Всем привет! Сегодня хочу углубиться в одну из самых важных тем в мире Zephyr OS — синхронизацию потоков и задач. Если вы хоть раз работали с k_thread_create , гоняли потоки туда-сюда и ловили bus fault, вы меня понимаете. Когда задача одна — всё просто. Но как только вырастает многопоточность, задачи начинают драться за общий ресурс — и тут без надёжной синхронизации не обойтись. У Zephyr OS есть три главных инструмента для этого: spinlock , mutex и semaphore . Каждый со своим характером и подводными камнями.
