Method for refreshing signal repeater in firmware of electronic device

Abstract

The invention provides a method for refreshing a signal repeater in firmware of an electronic device, which can be operated without restarting a system and comprises the following steps of: obtaininga memory address of a global variable; wherein a refresh value to be written into a signal repeater is pre-stored in the memory address of the global variable; comparing whether a true value of the signal repeater is consistent with the refreshing value in the global variable or not at preset time intervals, if so, continuing to execute the step, and if not, executing the next step; replacing thereal value of the signal repeater with a refresh value in the global variable; and completing the refreshing of the signal repeater.

Description

technical field [0001] The invention relates to a firmware refreshing technology in an electronic device, in particular to a method for refreshing a signal repeater in the firmware of an electronic device which utilizes address recognition to directly perform firmware refreshing to avoid system restart. Background technique [0002] In today's digital age, all kinds of electronic tools and devices are ubiquitous at home and 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 use of such electronic devices. Usually, such electronic devices sometimes include multiple programs (Programs) at the same time when they are r...

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
