How to Hack Any Micro-controller with a Raspberry Pi Pico…
summary
A cheap setup uses a Raspberry Pi Pico plus two high‑speed switches, a probe resistor and a logic analyzer/oscilloscope to perform precise voltage glitching timed by a record-and-replay of debugger traffic, avoiding writing a device driver. The method pinpoints a critical handshake, flips the Pico PIO for ~16 ns spikes and 150–400 ns effective glitches, and repeatedly injects until success; it repeatedly dumps firmware from an RO78 target, with higher success when undervolting or slowing the link.
