MCU-Link is the NXP single, unified debug probe architecture for all NXP general-purpose Arm® Cortex-M® based MCUs.
MCU-Link is implemented on NXP´s latest evaluation boards (known as MCU-Link OB) and standalone versions (MCU-Link
and MCU-Link Pro) are available for use with any system with a supported target MCU. MCU-Link uses common firmware
images for all implementations, with strap pins used to define the target type and supported features. MCU-Link is
based on the LPC55S69 microcontroller to provide high-performance debug over high-speed USB.
MCU-Link requires MCUXpresso IDE or MCUXpresso for VS Code to fully utilize all available features, but can also be used with third-party IDEs. MCU-Link can also provide USB to UART, SPI and/or I2C
interfaces (depending on MCU-Link type/implementation), a feature supported by the NXP open source LIBUSBSIO host
library for Windows, MacOS and Linux. MCU-Link is also compatible with the MCUXpresso SEC tools and FreeMASTER.
A free utility from NXP, also included with the LinkServer package, provides an easy way to install firmware updates.
