Explore a 51-minute conference talk from the 38th Chaos Communication Congress demonstrating live reverse engineering of a bare-metal U-Boot binary bootloader. Follow along as the presenter tackles the challenge of bypassing a locked bootloader encountered while hacking a babyphone, sharing practical techniques for obtaining serial logs, dumping and extracting firmware, and reverse engineering the U-Boot bootloader to retrieve the bootloader password. Learn valuable insights through hands-on demonstrations, complete with detailed explanations of funky hardware setups, UART logs, working with unknown base addresses, and helpful tips and tricks throughout the reverse engineering process.
