Embodiment Construction

[0047] The present invention will be further described below in conjunction with the accompanying drawings.

[0048] Common wireless communication terminals 100 include mobile phones and various wireless communication modules used in industrial control, security, wireless communication, monitoring, and automotive electronics. Software upgrades for wireless communication terminals 100 are mainly performed through FOTA upgrades. FOTA (Firmware Over-The-Air) refers to providing firmware upgrade services for devices with networking functions through cloud upgrade technology. Users use the network to obtain the system upgrade package of wireless communication terminal 100 in an on-demand and easy-to-expand manner, and perform cloud upgrade through FOTA , Complete system repair and optimization.

[0049] as attached figure 1 As shown, the wireless communication terminal 100 in the present invention may include: a processor 110, a memory chip 120, a communication unit 230 and other ...

Abstract

The invention discloses a FOTA upgrading method, a wireless communication terminal and a storage medium. The method includes: entering the standard mode, performing a backup process on the recovery partition; upgrading the recovery partition; entering the recovery mode, judging in turn whether each of the normal partitions is a partition to be upgraded, and if so, performing a backup process on the normal partition ; upgrade all normal partitions to be upgraded; the backup process includes: writing the partition index information of the partition to be upgraded in the backup partition; backing up the data of the partition to be upgraded to the backup partition. In the embodiment of the present invention, by backing up partition data before upgrading and restoring the data to the corresponding partition after the next power-on when the upgrade is interrupted, it is ensured that the memory chip can be verified to be normal when the upgrade fails again, and the problem caused by the upgrade failure is solved. The problem of difficult recovery of wireless communication terminals.

Description

technical field [0001] The invention relates to the field of information technology, in particular to a related technology for protecting the stability of partitions in memory chips. Background technique [0002] Wireless communication terminals are widely used in industrial control, security, wireless communication, monitoring, automotive electronics and other fields. Since wireless communication terminals usually work in a relatively harsh environment, if a power failure occurs during the FOTA (Firmware Over-The-Air) upgrade process of the wireless communication terminal, the upgrade of the wireless communication terminal may fail, resulting in wireless Communication terminal crashes, restarts, AT failures, etc., greatly affect the reliability of wireless communication terminals, and also bring a huge workload to the after-sales maintenance of wireless communication terminals. At present, in order to ensure normal startup after the upgrade fails, a backup partition is mad...
