Design of built-in boot loader for ARM uCOS

摘要

The paper describes the technical details of design and implementation of the built-in boot loader for ARM uCOS, including self-adapted booting technique, using of MMU, handle of interrupts, indirect setting of interrupt vectors, accessing of large page flash, programming for UART, etc. An example is provided to demonstrate the real effect of the built-in boot loader in ARM uCOS porting.
