Single-chip microcomputer upgrading method, single-chip microcomputer and storage medium

Abstract

The invention discloses a single-chip microcomputer upgrading method, a single-chip microcomputer and a storage medium, the single-chip microcomputer upgrading method comprises the following steps: monitoring and receiving an upgrading command and an upgrading sub-file of a serial port or an internet access, wherein the upgrading sub-file is obtained by slicing an upgrading file, and the upgrading sub-file comprises first verification information; verifying the data of the upgrading sub-file to obtain second verification information; and when the first verification information is consistent with the second verification information, sending a success instruction to an upper computer and storing the upgrading sub-file in an upgrading program partition. According to the single-chip microcomputer upgrading method, the problems of upgrading errors and error codes in the transmission process can be effectively reduced, and remote upgrading is supported.

Description

technical field [0001] The invention relates to the field of electronic technology, in particular to a method for upgrading a single-chip microcomputer, a single-chip microcomputer and a storage medium. Background technique [0002] Today, with the rapid development of science and technology, electronic products have penetrated into people's daily life and become an indispensable part of people. In the field of small intelligent management systems, many electronic products use single-chip microcomputers as the main control chip, especially single-chip microcomputers that run for a long time Features such as high reliability, low power consumption, and low cost can meet low-level requirements and are widely used in electronic products. [0003] In the process of using the single-chip microcomputer, it is necessary to continuously upgrade the single-chip microcomputer program according to user needs. Nowadays, the upgrade of MCU programs is usually based on IAP (In Applicatio...

AI Technical Summary

Problems solved by technology

Nowadays, the upgrade of MCU programs is usually based on IAP (In Application Programming, application compilation) technology, which is directly written into the designated program code area. There is no reliable mechanism during the upgrade process to prevent the occurrence of problems such as upgrade error programs and error codes during transmission. As a result, it cannot work normally after the upgrade, and it must be upgraded on site through a PC with the help of a designated programmer to connect to the MCU. Remote upgrade is not supported.
