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 present invention provides a firmware upgrade method based on openwrt and a router, the method comprising: S100 runs a preset upgrade script, and the preset upgrade script starts to create a ramfs file system in RAM; S200 generates a preset path and a ramfs file system in the ramfs file system Soft link; the preset path is the path to call the target firmware file from ROM; the soft link is the link address of the preset command; S300 erases Flash, and writes the target firmware file to Flash according to the preset path; S400 calls it in the ramfs file system The soft link performs a restart operation to complete the upgrade of the target firmware. The present invention avoids the problem that the device crashes and turns into a brick and cannot be restarted due to Flash destruction conflicts during the device upgrade process, greatly improves the stability of the upgrade, and makes the upgrade of the router to be upgraded 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...
