1 Introduction
The ST Micro Connect 2 is a host-target interface for single and multi-core SoCs, providing
fast access to host services. It can be used with STMicroelectronics’ development boards as
well as customer’s boards. It enables Windows XP, Windows 7 and Red Hat Linux hosts to
connect to a target development board with debug support.
The ST Micro Connect 2 provides support for multiple debug-links multiplexed onto a single
JTAG line. For multiple core debug, a single ST Micro Connect 2 replaces the need for
multiple ST Micro Connect 1s

used in conjunction with an ST-Multicore/MUX module. Its
physical size is comparable to an ST Micro Connect 1.
