Understanding MCUBoot: A Universal Bootloader for MCU Systems

Explanation: 1. The Bootloader handles the initial boot sequence on hardware before the operating system takes over. For example, U-boot is often used as the boot loader in embedded systems before starting embedded operating systems like Linux or FreeBSD. MCUBoot is also a bootloader, but it targets IoT, referring here to systems with limited memory … Read more
