Problems solved by technology

Since it needs to be erased during the upgrade process, it needs to be restarted after the firmware upgrade, which is a waste of time, and restarting will cause business interruption
In addition, the power cannot be cut off during the upgrade process. If there is a power failure or restart during the upgrade process, the system will not be able to return to normal.
[0004] Therefore, the existing firmware upgrade method may cause the system to fail to operate normally or business interruption, and the stability and security are poor.

Embodiment Construction

[0028] The technical solutions in the embodiments of the present application will be described below with reference to the drawings in the embodiments of the present application.

[0029] The method for upgrading firmware involved in the technical solutions of the embodiments of the present application can be applied to embedded devices. In addition, the firmware upgrade is implemented by patching. For the firmware of embedded devices, BUGs will inevitably appear, and patches can be used to specifically repair these BUGs. When upgrading, apply a patch to the firmware, and when the firmware runs next time, the BUG can be repaired through the applied patch, and the original problem will no longer occur. Therefore, patching the firmware is also a process of upgrading the firmware.

[0030] Based on the above application scenarios, please refer to figure 1 , the firmware upgrade method provided by the embodiment of the present application, the method includes:

Abstract

The invention provides a firmware upgrading method and device and a readable storage medium. The method comprises the steps of obtaining a patch file of a to-be-applied patch of current version firmware, wherein the patch file comprises a patch code, a patch space address and a skip list address corresponding to a patch; writing the patch code into the patch space address, wherein the patch spacecorresponding to the patch space address is a pre-erased space; modifying a skip list address corresponding to the patch into the patch space address, wherein the skip list spaces corresponding to theskip list addresses corresponding to the patches are pre-erased spaces. According to the method, the stability and safety of firmware upgrading are improved.

Description

technical field [0001] The present application relates to the technical field of the Internet of Things, and in particular, relates to a firmware upgrade method and device, and a readable storage medium. Background technique [0002] When upgrading the firmware of embedded products in the Internet of Things, it is necessary to download the firmware and save it to the memory (or to the reserved storage space), and then write the new firmware after erasing the original storage space. [0003] In the field of the Internet of Things, most embedded products use flash to store programs. When the device firmware is upgraded, the flash needs to be erased by sector (or entire block) before it can be rewritten. Since it needs to be erased during the upgrade process, it needs to be restarted after the firmware upgrade, which is a waste of time, and restarting will cause business interruption. In addition, the power cannot be cut off during the upgrade process. If there is a power cut ...
