MCU off-line burning method and device and storage medium

Abstract

The invention discloses an MCU (Microprogrammed Control Unit) off-line burning method, equipment and a medium. The method comprises the following steps: constructing an RISC-V system architecture, wherein the RISC-V system architecture comprises a burning upper computer, burning equipment and a target MCU (Microprogrammed Control Unit); the burning upper computer is connected to the burning equipment through a network connecting line; the burning equipment is electrically connected with the target MCU through the JTAG interface; controlling the burning upper computer to issue the production file to the burning equipment through the network connecting line; controlling the burning equipment to receive the production file, and storing the production file in the storage space; after judging that the production file is complete, disconnecting the network connection line; receiving a burning signal sent by a user, and reading the hex file in the storage space according to the burning signal; analyzing the hex file, and extracting a file address and production data of the hex file; and writing the production data into the target MCU through a JTAG protocol. According to the invention, MCU off-line burning based on the RISC-V architecture can be realized, the MCU burning efficiency is improved, and the production and maintenance cost is reduced.

Description

technical field [0001] The invention relates to the technical field of programming control, in particular to an MCU offline programming method, device and medium. Background technique [0002] RISC-V (pronounced "RISC-FIVE") is an open instruction set architecture (ISA) based on the principle of reduced instruction set computing (RISC), and V represents the fifth generation of RISC (reduced instruction set computer). Contrary to most ISAs, the RISC-V ISA is free to use in all desired devices, allowing anyone to design, manufacture and sell RISC-V chips and software. RISC-V is suitable for modern computing devices (such as warehouse-scale cloud computers, high-end mobile phones, and tiny embedded systems), and has the advantages of small size, fast speed, and low power consumption. [0003] However, most of the burning devices used to burn RISC-V architecture MCUs in the technology need to use OpenOCD as an intermediary or directly interact with GDB for burning. This online ...

Problems solved by technology

[0003] However, most of the burning devices used to burn RISC-V architecture MCUs in the technology need to use the OpenOCD intermediary or directly interact with GDB to burn. This online burning method needs to use a computer to burn through a downloader , cumbersome operation and low efficiency, especially in the stages of product mass production and on-site operation and maintenance, will greatly reduce production efficiency and increase production costs
