PiFex: JTAG Hacking with a Raspberry Pi
JTAG for Reverse Engineers
One of the main benefits of using one of these boards is that since the peripherals we are interested in are exposed as character devices in Linux, a wide variety of tools are available for interfacing with them, including most programming and scripting languages. By breaking out the commonly used interfaces and routing them through bi-directional level shifters, we aimed to streamline some of the initial steps when reverse engineering a new device or trying to learn how a new sensor works.
