Embodiment Construction

[0035] In order to make the purpose, technical solution and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present application, not to limit the present application.

[0036] The device startup method provided in the embodiment of the present application can be applied to a terminal device, and the terminal device can be a sports DV, a driving recorder, etc. In this embodiment, the sports DV is taken as an example, and the internal structure diagram of the sports DV can be as follows figure 1 shown. The motion DV includes an embedded processor, a display screen, a lens module and a communication module connected through a system bus. Among them, the lens module of the sports DV includes lens combinations for photography, photosensitive components, trans...

Abstract

The present application provides a device startup method, device, computer device and storage medium, the method includes: calling a driver to read a virtual memory file from a flash memory partition into the memory; the virtual memory file includes files that have nothing to do with business logic , call the kernel to obtain the address of the virtual memory file in the memory, call the kernel to obtain the virtual memory file from the memory according to the address, and then call the kernel to load resources according to the virtual memory file, business logic file and configuration file to start the device, because according to the driver Naked read flash memory partition to memory is faster than the kernel itself to read flash memory partition to memory, and only needs to use modules such as the virtual memory file of the kernel, without adding software resources such as RTOS, and thus can achieve less resource requirements. In the case of simple development, the device startup time is reduced.

Description

technical field [0001] The present application relates to the technical field of computer operating systems, and in particular to a method and device for starting a device, a computer device and a storage medium. Background technique [0002] As the Linux operating system is more and more widely used in terminal equipment such as sports DVs, driving recorders, and smart phones, the requirements for its execution speed are also getting higher and higher. How to reduce the cold start time of equipment has become an issue of increasing concern. [0003] The traditional fast cold start solution is realized by dual-core and dual-system. Specifically, one core is used to run a real-time operating system and load modules related to the minimum business logic, and the other core runs a Linux operating system to realize WIFI, UI, USB, Network-related App and other services. [0004] However, the above-mentioned fast cold start solution of dual-core plus dual-system has the problem o...
