In security audits of embedded systems, retrieving firmware is the critical first step. When over-the-air updates are encrypted and debug ports (UART, JTAG) are disabled in production silicon, dumping physical SPI Flash memory becomes necessary. This writeup covers extracting firmware from an 8-pin SOP SPI flash chip using a Bus Pirate and flashrom to bypass bootloader lockdowns.
