Using OpenOCD (Open-On-Chip Debugger) with STM32F411CE: A Practical Guide

Author: Shafeeque Olassery Kunnikkal | Category: IoT, Penetration Testing, STM32F411 | Leave a Comment

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…..
