Laser Fault Injection on a Budget: RP2350 Edition

This article details how a custom-built, low-cost laser fault injection platform was used to successfully bypass the secure boot mechanism of Raspberry Pi's RP2350 microcontroller. Using an infrared laser, the platform cleverly circumvented the RP2350's glitch detectors. A single laser pulse injected a fault, altering the boot ROM's instruction flow, ultimately revealing hidden data. The author provides detailed explanations of the platform's hardware design, software architecture, and the attack process, including manufacturing files and source code.
