In their own words
MCUXpresso SDK
MCUXpresso SDK is an open-source development kit for NXP processors and evaluation boards. It combines peripheral drivers, device headers, RTOS support, connectivity stacks, middleware, reference software, and example applications for NXP Arm Cortex-M devices and 32-bit digital signal controllers. The SDK Builder lets developers select an MCU or board and optional components to create a tailored package; GitHub repositories and Open-CMSIS-Packs provide other delivery routes. Supported tools include MCUXpresso IDE and its VS Code extension, IAR Embedded Workbench, Keil MDK, and the CLI GNU toolchain. Its components cover USB, Bluetooth, Wi-Fi, NFC, OpenThread, AI inference, audio, security, graphics, motor control, and file systems. FreeRTOS and Zephyr are listed RTOS options. The SDK supports Windows, macOS, and Linux hosts, with CMake, Kconfig, west, Ninja, and IDE project generation among its build options. The core project uses BSD-3-Clause, though other projects may differ; partner software may require a separate license. LTS GitHub releases receive two years of back-ported security and severe bug fixes; quarterly releases have no maintenance. Customized ZIP packages typically range from 500 MB to 2 GB.
