It provides both a command-line interface with subcommands for common tasks (gdbserver, load, erase, reset, rtt, etc.) and a Python API for custom control and automation. The tool supports more than 70 popular MCUs natively and can extend support through CMSIS Device Family Packs to cover nearly every Cortex-M device on the market.\n\nThe package is built on 17 runtime dependencies including capstone for disassembly, hidapi and pyusb for USB communication, pyelftools for ELF parsing, and cmsis-pack-manager for device pack handling. It offers memory read/write, register access, breakpoint and watchpoint management, flash programming, binary/hex/ELF file loading, SWO/SWV support, and CoreSight DP/AP access. Configuration is supported through config files, user scripts, and direct API use, making it suitable for both interactive debugging and CI/CD test automation.","worth_installing":"Yes. pyOCD is actively maintained, has low install friction, carries no security vulnerabilities, and is licensed permissively. It is the right choice if you need a Python-native, cross-platform debugger for Cortex-M development or CI automation. The only prerequisite is a supported debug probe and libusb; if you have those, installation and basic use are straightforward."},"id":"pyocd","links":{"html":"https://skillfed.io/packages/pyocd","md":"https://skillfed.io/packages/pyocd.md","pypi":"https://pypi.org/project/pyocd/"},"maintenance":{"status":"active"},"meta":{"latest_release":"2026-07-21","license_spdx":null,"license_treatment":"permissive","name":"pyocd","python_support":"supports_current","summary":"Cortex-M debugger for Python"},"popularity":{"monthly_downloads":1372352,"position":3991,"tier":"top_5000"},"security":{"n_vulnerabilities":0},"version":"0.45.1"}
