BootLoader architectural design method

Abstract

The invention discloses a BootLoader architectural design method, which comprises the following steps of: dividing a Flash address space into five areas which are respectively a code area, a configuration area, a parameter area, an image area and a data area; starting the initiation in the code area being responsible for the hardware platform; storing the relevant configuration files of a processor and the configuration files of the peripheral hardware in the configuration area, which are called by the starting code; storing the parameters for transferring between the starting code and the operating system in the parameter area; storing the copy of an internal kernel image in the image area, which can be debugged, maintained and updated at any time; and storing application software and user data in the data area. The BootLoader architectural design method provided by the invention has clear structure, more powerful function, convenient maintenance and modification, strong expandability, and obvious advantage on the aspect of software update and functional expansion.

Description

technical field [0001] The present invention relates to a BootLoader architecture design method, in particular to a BootLoader architecture design method with clear architecture, more powerful functions, easy maintenance and modification, strong scalability, and obvious advantages in software update and function expansion. Background technique [0002] Embedded systems are application-centric, with tailorable software and hardware, and are suitable for special-purpose computer systems with comprehensive and strict requirements on functions, reliability, cost, volume, and power consumption. It has the characteristics of small software code, high automation, and fast response speed, and is especially suitable for systems that require real-time and multi-tasking. Embedded systems are mainly composed of embedded processors, related supporting hardware, embedded operating systems, and application software systems, which can work independently. [0003] BootLoader is a program us...

AI Technical Summary

Problems solved by technology

[0004] The embedded operating system without BootLoader has poor flexibility, lacks the information interaction process with the user, and cannot realize convenient and effective parameter transmission

Every time you modify the software and hardware of the system, you need to modify the system software, recompile, debug, and download the operating system, which prolongs the development cycle and wastes a lot of resources, which is not conducive to system upgrades and maintenance

[0005] At present, many operating systems with BootLoader are designed for a specific microprocessor platform. Hardware modification will have a great impact on the software. The workload of software modification is relatively large, so the flexibility is not enough.
