Openwrt-based firmware upgrading method and router

A firmware upgrade and router technology, applied in electrical components, digital transmission systems, program control devices, etc., can solve problems such as the inability to use preset commands of the router to be upgraded, the inability to use the router to be upgraded, and the inability to stably upgrade the device. Write upgrades are safe and reliable, reduce the cost of returning to the factory for repairs or replacing new equipment, and improve the effect of upgrade security

Problems solved by technology

[0003] The current router to be upgraded directly erases the entire file system of the router to be upgraded. As a result, when the user upgrades the router, if the currently running file system is damaged, the preset commands in the router to be upgraded may become unusable. As a result, the router to be upgraded cannot be used, and the device cannot be upgraded stably, or even used normally.

Abstract

The invention provides an openwrt-based firmware upgrading method and a router. The method comprises the following steps: S100, running a preset upgrading script, and creating a ramfs file system in aRAM by the preset upgrading script; S200, generating a preset path and a soft link in the ramfs file system, wherein the preset path is a path of calling a target firmware file from the ROM, and thesoft link is a link address of a preset command; S300, erasing Flash, and writing the target firmware file in the Flash according to the preset path; and S400, calling the soft link in the ramfs filesystem to execute a restart operation so as to upgrade the target firmware. By adoption of the openwrt-based firmware upgrading method, the situation that the device crashes and cannot be restarted caused by Flash breakage conflict and the like in a device upgrading process, so that the upgrading stability is greatly improved, and the erasing upgrading of the to-be-upgraded router is safer and more reliable.

Description

technical field [0001] The invention relates to the field of router upgrades, in particular to an openwrt-based firmware upgrade method and a router. Background technique [0002] When we use a router, most of us may not realize that this device that distributes the network signal to each computer actually has software running on it. On the router, we call it firmware. When there is a problem with the user's equipment, especially when there is a more complicated problem that cannot be repaired by restoring the factory settings, it is neither economical, convenient, nor suitable for maintenance to replace the hardware and equipment at this time, as long as it is not the hardware. The best way at this time is to flash the machine (also known as flashing the firmware). Reinstalling or upgrading the firmware of the router through the upgrade function in the router management interface can greatly improve the overall performance of the router. [0003] The current router to be u...
