ARM 공부

Chapter 2. Learning ARM

2-1. Why we have to learn ARM architecture?

2-1-1. For bring up

• What is bring-up? → 보드가 부팅부터 일반적인 동작이 가능한 수준까지 기본적인 세팅을 하는 작업
• Hardware development sequence: Board bring-up → Stabilization → Maintenance
  - in bring-up sequence, usually do..
  1. boot loader(start-up code)
     cf) start-up code: first code that execute when device start
     - MMU, hardware, cache setting
     - stack assigment
     - exception handler build
  2. system resource(cache, memory) initialize
  3. external device(USB, mouse) initialize

2-1-2. For better device development

• Embedded code optimization

2-1-3. For better understand about LINUX kernel or RTOS

2-1-4. Debugging
