Problems solved by technology

[0005] In order to increase the update and iteration function of electronic products, the update function of electronic products can be realized through wireless programming, and the problem that the products cannot be updated and upgraded because they are sealed in the shell layer by layer or cannot be separated by distance is solved. Therefore, the present invention provides a IAP method and system based on stm32 microcontroller

Abstract

The invention discloses an IAP method and system based on a stm32 single-chip microcomputer. The method comprises the steps of programming a BootLoader program to the single-chip microcomputer; programming the APP program to the single-chip microcomputer; and running the BootLoader program to update the APP program. The method provided by the invention can remotely control the upgrading of the program; Mechanical operation is not needed, for example, a burner is connected, and a jumper cap is arranged. Performing repeated programming; When the shell of the machine is sealed, the machine cannotbe disassembled, and an IAP upgrading scheme can be used for updating iteration.

Description

technical field [0001] The invention relates to the technical field of single-chip microcomputer software upgrade, in particular to an IAP method and system based on an stm32 single-chip microcomputer. Background technique [0002] IAP, the full name is "In-Application Programming", and the Chinese interpretation is "programming in the program". IAP is a technology to update the microcontroller running the program in real time through the external communication interface of the microcontroller (such as USART, IIC, CAN, USB and other communication ports). The current upgrade methods on the market are basically ICP (In-Circuit Programming) technology, which is to program the MCU through an online emulator, while ISP technology is a programming technology guided by the bootloader program in the MCU. [0003] Whether it is ICP technology or ISP technology, mechanical operations such as connecting the download cable and setting jumper caps are required. If the circuit board of t...
