LibSWD is an Open-Source framework to deal with with Serial Wire Debug Port in accordance to ADI (Arm Debug Interface, version 5.0 at the moment) specification. It is released under 3-clause BSD license. For more information please visit project website at http://libswd.sf.net

Serial Wire Debug is an alternative to JTAG (IEEE1149.1) transport layer for accessing the Debug Access Port in ARM-Cortex based devices. LibSWD provides methods for bitstream generation on the wire using simple but flexible API that can reuse capabilities of existing applications for easier integration.

LibSWD is almost standalone and can be easily integrated into existing utilities for low-level access and only requires in return to define driver bridge that controls the physical interface interconnecting host and target.
