Abstract

The invention discloses a firmware upgrading method and device, computer equipment and a storage medium. The method comprises the steps that connection with a server is established, and new firmware is acquired from the server; first target data, second target data and third target data contained in new firmware are written into a verification partition, a function partition and an upgrading partition of the embedded device respectively, wherein the new firmware is used for conducting firmware upgrading on the embedded device; if the embedded device is restarted during firmware upgrading, the first target data is not abnormal when being written into the verification partition, the third target data is abnormal when being written into the upgrading partition, and whether the third target data is backed up in the function partition or not is judged, then data recovery is conducted on the upgrading partition according to the third target data backed up in the function partition; and the process returns to execute the step of establishing the connection with the server and obtaining the new firmware from the server. Therefore, the use of the storage space is saved while the upgrading damage possibility is effectively reduced, and the cost is further reduced.

Description

technical field [0001] The present application relates to the field of computer technology, in particular to a firmware upgrade method, device, computer equipment and storage medium. Background technique [0002] In recent years, embedded devices have been widely used and developed rapidly because of their advantages such as low cost, high reliability, rich code, application program scalability and portability. With the improvement of the system function, performance and scale of embedded devices, the firmware of embedded devices needs to be upgraded during the use of embedded devices, and the system can be maintained and upgraded in time according to the needs of customers, and the system performance can be improved. performance. [0003] At present, embedded devices perform firmware upgrades by downloading new firmware from the cloud and then writing the new firmware. In order to avoid unexpected power failures and other abnormal situations during the upgrade process, res...
