Overview Now that you’ve wired your STM32 Black Pill to an Arduino running JTAGenum and captured output via PuTTY, it’s time to make sense of the data. This part walks you through interpreting FOUND! lines, verifying the detected pins, and locking down a reliable JTAG configuration for future debugging. Step 9: Understanding the Output Format…..

Overview Now it’s time to automate discovery. We’ll use a tool called JTAGenum, which runs on an Arduino and probes the target’s pins to discover JTAG lines. In this step, you’ll set up an Arduino board with the JTAGenum firmware and wire it to the STM32. This allows you to scan multiple GPIO pins and…..

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…..
