Abstract

The invention provides a lightweight operating system kernel and drive separation method. The method is used for solving the problem of mutual coupling of an operating system kernel and a drive when an operating system kernel unit and a driving unit are compiled and linked together. The driving unit and the operating system kernel unit are mainly included. By adopting the method for separating thekernel unit and the driving unit of the lightweight operating system, independent compiling and linking of the kernel unit and the driving unit of the operating system can be realized, and code segments and data segments of each unit can be separated, so the kernel unit and the driving unit of the operating system can be upgraded independently, data of other units can be prevented from being modified when the data areas of the kernel unit and the driving unit of the operating system are out of boundaries in a small-range memory, and the problem of quick positioning according to the address space where the address is located when a program goes wrong can be solved.

Description

technical field [0001] The present disclosure relates to the embedded field and the real-time operating system field, and in particular relates to a method for separating a lightweight operating system kernel and a driver. Background technique [0002] In the traditional embedded real-time operating system, the operating system kernel unit and the driver unit are compiled and linked together, and the functions and data in the operating system kernel unit and the driver unit are mixed together, so even if only the modified After a small part of the code is recompiled and linked, the entire operating system also needs to be upgraded, which is inconvenient when the unmodified part takes up most of the space. At the same time, after the operating system kernel unit is separated from the drive unit, when a small range of memory access crosses the boundary in the drive unit, it will only interfere with the drive unit itself, without affecting the stability of the operating system ...
