A method for refreshing a signal repeater in an electronic device firmware

Abstract

The present invention provides a method for refreshing a signal repeater in the firmware of an electronic device, which can be run without restarting the system. The method includes: obtaining a memory address of a global variable; and writing a refresh value in a signal repeater. Pre-stored in the memory address of the global variable; every predetermined time, compare whether a real value of the signal repeater is consistent with the refresh value in the global variable, if it is consistent, continue to execute this step, if not, execute the next step The steps are: replacing the real value of the signal repeater with the refresh value in the global variable; and, completing the refresh of the signal repeater.

Description

technical field [0001] The invention relates to a firmware refresh technology in an electronic device, in particular to a refresh method for a signal repeater in the firmware of an electronic device which utilizes address recognition and directly performs firmware refresh to avoid system restart. Background technique [0002] In today's digital age, all kinds of electronic tools and devices are ubiquitous at home and at work, such as computers, smart phones, game consoles, etc. These electronic devices can provide a variety of help, planning and communication, Its applications range from information dissemination, industrial manufacturing and even entertainment. Generally speaking, maintaining the normal operation of these electronic devices to provide a smooth and barrier-free user experience is the most important issue in the application of such electronic devices. Usually, such electronic devices sometimes include multiple programs (Programs) at the same time when runnin...

Problems solved by technology

[0011] However, there is an obvious shortcoming in the aforementioned firmware refresh method PAS1, that is, in step PAS108, if the refresh value in the global variable is to be poured into the register in the signal repeater to become a real-time real value, the expander must be activated. initialization, that is, the expander needs to be restarted (Reset)

However, in the well-known technology, the restart of the expander means that the related floppy hard disk (usually marked with a different drive letter) is unable to perform I / O operations, that is, when the firmware is refreshed, the system operation The real-time online business must be stopped; as a result, commercial interests, customer rights and operational efficiency will inevitably be affected to a considerable extent
