Arduino to switch from Arm Mbed to Zephyr RTOS

Following Arm’s decision to stop supporting Mbed from July 2026 onwards, Arduino has now decided to use Zephyr RTOS instead of Arm Mbed for Arduino boards that rely on the latter including Arduino GIGA, Arduino Nano 33 BLE, Arduino Nano RP2040 Connect, as well as Arduino PRO boards/solutions such as the Portenta, Nicla, and Opta families. Note that Arduino UNO, MKR, and Nano families are not impacted by the change since their Arduino Core implementation does not rely on Mbed. The change is not going to happen overnight as software development takes time, and Arduino plans to release the first beta based on ZephyrOS by the end of 2024. and a rollout for various boards starting in 2025 long before Arm Mbed is phased out for good. Arduino is not new to the Zephyr project as the company became a Silver member last year, and they were aware that Arm […]

RT-Thread Vision board review – Part 1: OpenMV on Renesas RA8D1 Cortex-M85 microcontroller

RT-Thread VIsion board vs WeAct STM32H743

I am always interested in real-time operating systems (RTOS) for microcontrollers (MCUs) with my past backgrounds in µC/OS-II, mbed, and FreeRTOS. When the opportunity arose to get my hands on the RT-Thread Vision Board, thanks to the RT-Thread team and CNX Software, I was excited to check it out. This board, a collaboration between RT-Thread and Renesas, packs a powerful Renesas RA8D1 Cortex-M85 MCU and comes pre-loaded with OpenMV firmware. OpenMV’s MicroPython engine lets you jump right into embedded vision development, perfect for experimenting with computer vision tasks. But the real power lies in RT-Thread’s ability to handle tasks very quickly, which we’ll explore with C/C++ development in part two. This first part will focus on getting you familiar with the hardware using the OpenMV firmware, making it a smooth entry point for beginners. Plus, I have a collection of other Renesas evaluation boards, so you can bet I’ll be […]

Rockchip RK2118G/RK2118M dual-core Star-SE Armv8-M microcontrollers target smart audio applications

Rockchip RK2118G microcontroller block diagram

Rockchip RK2118G and RK2118M smart audio microcontrollers based on a dual-core Star-SE Armv8-M processor, an NPU for smart AI audio processor, three DSPs, 1024KB SRAM, optional DDR memory in package, and a range of peripherals. I first noticed the RK2118M in slides from the Rockchip Developer Conference 2024 last March, but I did not have enough information for an article at the time. Things have now changed since I’ve just received a bunch of datasheets including the one for the RK2118G and RK2118G microcontrollers, which look identical except for the DDR interface and optional built-in 64MB RAM for the RK2118G. The datasheets have only one reference to Arm with the string “Arm-V8M” and nothing else, and Cortex is not mentioned at all. But the slide above reveals the STAR-SE core looks to be an Arm Cortex-M33 core. We also learn the top frequencies for the “STAR-M33″/”STAR-SE” core (300MHz) and the […]
