Problems solved by technology

However, with the diversification of products on the market, the disadvantages of this software upgrade mode have gradually emerged, especially for terminal devices such as watches and vehicle-mounted modules that do not have redundant buttons and exposed pins for operation. If the download is interrupted by a sudden power failure or other reasons during the upgrade process, the system will be damaged and cannot work, and the terminal device will no longer be usable

Abstract

The embodiment of the invention provides a software upgrading method and device, which are applied to terminal equipment comprising a first memory, the terminal equipment is currently in a system software upgrading process, and the method comprises the following steps: if the terminal equipment is powered off, determining the integrity of a first auxiliary downloading file SPL stored in the firstmemory; if the first SPL is incomplete, entering a boot loader downloading mode after the terminal equipment is powered on, wherein, in a first stage of the boot loader download mode, the terminal device executes the following steps: deleting the first SPL; and downloading a second SPL in a target external storage medium into the first memory, wherein the second SPL is a file which is finally downloaded into the first memory in the first stage. By adopting the embodiment of the invention, the terminal equipment can be powered on again to finish software upgrading after being powered off in thesystem software upgrading process.

Description

technical field [0001] The present application relates to the field of electronic technology, and in particular to a software upgrading method and device. Background technique [0002] At present, most electronic products on the market start the upgrade by entering the software upgrade mode when the terminal device is turned off and the external button confirms that U1TXD (NBOOT) is grounded. This software upgrade mode is fast, reliable and can be upgraded repeatedly. However, with the diversification of products on the market, the disadvantages of this software upgrade mode have gradually emerged, especially for terminal devices such as watches and vehicle-mounted modules that do not have redundant buttons and exposed pins for operation. During the upgrade process, if the download is interrupted by a sudden power failure or other reasons, the system will be damaged and cannot work, and the terminal device will no longer be usable. Contents of the invention [0003] The e...
