Abstract

The embodiment of the invention relates to the technical field of operating systems, and provides an operation method and device for modularization management of a real-time operating system and equipment. The operation method for the modularization management of the real-time operating system comprises the following steps: operating a virtual machine in an ELF format in the real-time operating system; in response to an operation starting instruction of an application program, converting the application program into a file in the ELF format; adopting the virtual machine to load and analyze the file in the ELF format to obtain analyzed codes; and operating the analyzed codes in the real-time operating system. According to the embodiment of the invention, the system security and compiling flexibility can be improved.

Description

technical field [0001] The present invention relates to the technical field of operating systems, in particular to an operating method based on modular management of a real-time operating system, an operating device based on modular management of a real-time operating system, and an operating device based on modular management of a real-time operating system. Background technique [0002] At present, many commonly used RTOS such as freertos, ucos, etc. do not provide dynamic module loading function, which limits their flexibility, and also makes it necessary for the entire project to be compiled and reprogrammed if an APP module running on the system is updated. to the board. If you upgrade through the cloud platform, you need to download the complete image, which is very inconvenient for embedded devices with limited space and resources. If you implement a virtual machine to dynamically load an updated module, similar to Linux dynamically loading ko files, then Can be very...
