Embodiment Construction

[0053] The following will clearly and completely describe the technical solutions in the embodiments of the application with reference to the drawings in the embodiments of the application. Apparently, the described embodiments are only some of the embodiments of the application, not all of them. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of this application.

[0054] Explanation of terms:

[0055] UART communication protocol: UART is Universal Asynchronous Receiver and Transmitter, universal asynchronous transceiver (asynchronous serial communication port). The UART communication protocol is a general data communication protocol, which includes RS232, RS499, RS423, RS422 and RS485 and other interface standard specifications and bus standard specifications, that is, UART is the general term for asynchronous serial communication ports.

Abstract

The invention provides a software program upgrading method and system and a terminal. The method is applied to a main control chip of the terminal in the software program upgrading system, the terminal further comprises an external storage chip connected with the main control chip, and the system further comprises a server connected with the terminal. The method comprises the steps that a software program upgrading command is stent to the server; target data sent by the server is received and stored in the external storage chip, wherein the target data comprises a target software program; the original software program is upgraded by using the target data in the external storage chip. Due to the fact that the price of the external storage chip is relatively low, the cost of the terminal cannot be increased additionally; meanwhile, according to the embodiment, an original software program can be accurately upgraded by using the method.

Description

technical field [0001] The present application relates to the technical field of communication, and in particular to a software program upgrading method and system, and a terminal. Background technique [0002] At present, the software programs in the air conditioners are all preset at the factory, and usually do not have the function of remotely upgrading the software programs. The main reason is that the resources of the main control chip in the air conditioner are limited. [0003] In order to reduce the cost of air conditioners, the main control chips of most air conditioners currently use low-cost MCUs, and the capacity of Flash chips is relatively small. [0004] However, in the process of upgrading the software program, two software programs (the original software program and the new software program) need to be stored, and the capacity of the Flash chip in the main control chip is limited to storing one software program, so the current main control chip The function...
