1. Concept Introduction 1.1 What is the Boot Process of a Microcontroller? The boot process of a microcontroller refers to a series of initialization steps that occur from the moment power is applied or the device is reset until the user code begins execution. Different microcontrollers have specific details in their boot processes, but most … Read more
Why U-Boot is Needed1.1. Main Components of Computer Systems(1) A computer system is a system centered around the CPU. Typical computer systems include: PCs (desktop + laptop), embedded devices (smartphones, tablets, game consoles), and microcontrollers (home appliances like rice cookers, air conditioners).(2) There are many components that make up computer systems, and different computer systems … Read more
