OpenOCD and JTAG/SWD debugging: flash firmware, attach GDB, set hardware breakpoints

Prerequisites: an MCU board, a working debug probe (J-Link, ST-Link, CMSIS-DAP, or FTDI), and OpenOCD + arm-none-eabi-gdb installed — this skill drives real hardware Install "OpenOCD and JTAG/SWD debugging: flash firmware, attach GDB, set hardware breakpoints" for me. It gives my agent @mohitmishra786's embedded-debugging workflow: JTAG vs SWD selection, OpenOCD configs for CMSIS-DAP/ST-Link/J-Link/FTDI adapters and common targets, GDB attach via extended-remote :3333 with reset-halt/load flows, firmware flashing (ELF, telnet, script mode), hardware breakpoints and watchpoints with Cortex-M limits, a monitor-command reference, and a common-errors table with fixes. MIT licensed. Repository: https://github.com/mohitmishra786/low-level-dev-skills/blob/main/skills/embedded/openocd-jtag/SKILL.md 1. Fetch the SKILL.md file (and any helper files) from the repository path into a temporary folder and summarize what it does in one or two sentences. 2. Safety check: review the SKILL.md and scripts for anything suspicious (unexpected network calls, shell commands, credential harvesting). This repo should contain zero secrets in code, credentials only via the secure vault, allowed hosts declared in the SKILL.md. Verify that holds here; STOP on any red flag and tell me. 3. Install it as a skill: copy SKILL.md and its helper files into the agent's skills directory, in a folder named "openocd-jtag". 4. Verify with no network calls: frontmatter valid, files in place. 5. Report what was installed, where, and what I still need to do myself (e.g. connect the probe to my board, pick the .cfg matching my exact MCU part number, and double-check every firmware image and flash address before running — flashing real hardware is destructive; Segger JLinkGDBServer is a documented alternative). GitHub is optional: if I have a GitHub account or the gh CLI, you may use it; otherwise public access is fine. Never require it unless it's in the prerequisites above. Rules: don't touch anything outside the temp folder and the install target. If anything looks off, stop and ask me.
