: This is a binary dump of the SPI EEPROM chip. Unlike OTP, this memory is rewritable. It typically stores the bootloader firmware, hardware configurations, and sometimes encryption keys for external storage. 2. Role in Raspberry Pi (4 and 5)
Extraction methods vary by device but generally require "low-level" access tools. otp.bin seeprom.bin
: It stores immutable data like the serial number, MAC address, and board revision. More importantly for advanced users, it holds the "warranty bit" and secure boot configurations, such as the public key hash for verifying signed firmware. : This is a binary dump of the SPI EEPROM chip
: Contains the "Console Key," which is unique to every single unit. seeprom.bin : Contains keys for USB data storage encryption. otp.bin seeprom.bin
