The MCU-Debug Core

A modern, drop-in replacement for cortex-debug. Offers transparent remote probe support (WSL2/containers/SSH), dual-mode RTT polling, workspace-scoped UARTs, and a standalone CLI/TUI.

Companion Extensions

Extend your environment with dedicated visualizers: SVD Peripheral Viewer, community-driven RTOS Views (with contributions from ARM), and the high-performance MemoryView.

DAP-Compatible & Modular
