Redboot IntroductionRedboot is designed for Embedded debugging and startup environments. It is an Ecos-based application that uses the hardware abstraction layer (HAL) of eCos as its basis. It is a basic function as bootloader, but can be used in any embedded system or any embedded real-time operating system. It can also be used for debugging during the product development cycle or for flash or network startup in published products. Features: STARTUP script support; Management and control of

Serial Port printing information can be added to any code to facilitate debugging. You do not have to have a printf statement. This can be implemented in a simple way.
