Overview Once you’ve discovered your JTAG pins using JTAGenum, you might want to enable them in your own firmware, or use them with a tool like OpenOCD for real debugging. This part shows how to: Why Enable JTAG in Firmware? On many STM32 boards, including the Black Pill: When is this needed? Enabling JTAG Using…..

Introduction In this walkthrough, we’ll dive into using OpenOCD to interact with embedded systems via JTAG for debugging and analysis. Our target will be the STM32F411CE microcontroller, specifically the STM32F411CE Lab 3 – Challenge-Response System to understand real-world debugging and firmware application. This hands-on exercise is designed to introduce real-world IoT pen testing techniques—covering memory…..

This post is the result of my first deep, hands-on experience generating a full technical article using ChatGPT!Together, we explored how to implement a challenge-response system on STM32, refine C code, modularize functions, fix compiler warnings, and prepare polished documentation. Along the way, I encountered not just technical hurdles (like sandbox download issues, expired file…..
