Researchers used photon-emission microscopy to locate a register controlling debug enablement on the Raspberry Pi RP2350 microcontroller. By targeting two nearby spots with laser pulses, they restored Secure-world debugger access and recovered a secret from OTP memory after a rescue reset halted firmware locking. The attack requires physical access, destructive setup, and expensive lab equipment.
