Introduction This hands-on guide is designed for learners who want to understand how to find JTAG debug pins on a microcontroller board like the Adafruit Black Pill (STM32F411CE). No prior knowledge of JTAG or embedded debugging is assumed — you’ll learn using a multimeter, Arduino, and free tools. The Adafruit Black Pill (STM32F411CE) is a…..

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…..
