This application discloses a terminal, method and system for realizing remote upgrade of CAN network based on XC7Z045 chip, belonging to the field of computer technology. The system includes an upgrade server and a terminal. The upgrade server and the terminal communicate through the CAN bus. The upgrade server sends operating system upgrade instructions, system upgrade data packets and program upgrade data packets through the terminals under the CAN bus. The terminal modifies the system according to the operating system upgrade instructions. The upgrade refers to the status of the circuit, the operating system is upgraded according to the system upgrade data package, and the relevant application programs are upgraded according to the program upgrade data package. In this application, a CAN bus is set between the upgrade server and the xilinx XC7Z045 chip, and the upgrade server can send system upgrade instructions and system upgrade data packets to the xilinx XC7Z045 chip through the CAN bus, which simplifies the complexity of the equipment while avoiding the use of Ethernet. Make the interface of the system smaller, lighter and less costly.
Description
technical field [0001] The invention belongs to the technical field of computers, and in particular relates to a terminal, a method and a system for realizing CAN network remote upgrade based on an XC7Z045 chip. Background technique [0002] At present, the application requirements for the operating system are getting higher and higher (miniaturization, informatization, networking, digitalization, high reliability, and high performance), and more and more functions are realized. Adding functions means adding more Device or increase the function and performance of the device, which will inevitably lead to the increase of overall solution loopholes and interfaces, and increase the complexity of the software. Some software loopholes cannot be predicted in advance. In order to repair and update various loopholes and files in time, how to cut These vulnerabilities external resources are a long-term research work. [0003] Traditional operating systems and software updates genera...
