Famed hardware hacker Joe Grand has released his latest open source project, the JTAGulator. This tool assists hardware hackers in identifying on-chip debugging (OCD) and/or programming connections from test points, vias, or component pads on a target piece of hardware. It interfaces with your computer via USB communicating through any terminal program. It’s based on the Parallax Propeller.
