specific example

[0045]This invention mainly adopts STM32F103xx series single-chip microcomputer and ENC28J60 Ethernet control chip, designs a method with BootLoader function, and can remotely update firmware through network interface, and describes its design principle and realization process in detail.

[0046] Utilizing the characteristics of STM32F103xx series single-chip self-reading and writing on-chip program space, first write the BootLoader program in the on-chip Flash, and then use the BootLoader program to erase and write the user program on the single-chip microcomputer without using the traditional emulator and JTAG interface way to do programming work.

[0047] The STM32F103xx series microcontrollers are based on the ARM Cortex-M3 core and are designed for high-performance, low-cost, and low-power embedded applications. It has a clock frequency of up to 72MHz, on-chip integrated 32-512KB Flash memory, which can be used to store programs and data, 6-64KB SRAM memory, which can be ...

Abstract

The invention discloses the achievement of a single chip microcomputer firmware upgrading method based on a network, wherein the specific achievement process comprises the following steps of firstly designing memory address space of a BootLoader program and a user program in an internal memory of a single chip microcomputer; programming the BootLoader program by utilization of a JTAG (Joint Test Action Group) interface or an emulator, wherein the BootLoader program has module functions of reading, writing and erasing memory data, jumping program addresses and downloading network data; writing the BootLoader program in an on-chip Flash; erasing and writing an on-chip user program in the single chip microcomputer through the BootLoader program so as to realize remote upgrading and operation of the user program in the on-chip Flash. Compared with the prior art, the achievement of the single chip microcomputer firmware upgrading method based on the network has the advantages that the remote upgrading of the system firmware of the single chip microcomputer is realized, the convenience of the product firmware upgrading is improved, the system maintenance cost can be reduced at the same time, better economic benefits can be produced, and the effects of higher actual engineering application values, strong practicability, wide application range and easiness in popularization are achieved.

Description

technical field [0001] The invention relates to the technical field of computers, in particular to the realization of a network-based single-chip firmware upgrading method with strong practicability. Background technique [0002] With the continuous complexity and diversification of control equipment, it is no longer possible for the system to rely on only one control program to satisfy different users, and the needs of the same user are not static. This requires that the control system can support the upgrade function of the firmware program, and the firmware program can be easily updated before or after the sale. [0003] The software maintenance and upgrading of single-chip microcomputer hardware products need manual on-site programming or replacement of the latest firmware chips to complete, especially in the case of harsh working environments, which makes it very difficult to upgrade and maintain single-chip microcomputer application systems. [0004] After the release...
