Problems solved by technology

[0002] When updating the program to the target device, the process of updating the program is the process of data flashing. The data flashing speed is usually limited by the baud rate, load rate and the throughput of the gateway for data interaction. The flashing process is relatively slow. long
[0003] With the iterative development of the program, the complexity of the function will continue to increase. If a certain flash memory partition is not enough, it will be re-divided, and the entire partition structure will need to be adjusted. The upper and lower computers will re-upgrade the software, resulting in incompatible software versions. The problem is that it will take a long time to refresh the whole area at the same time

Abstract

The invention discloses a data flashing method and device, equipment and a storage medium, and the method comprises the steps: an upper computer analyzes a compiled program file to obtain code segment data, data segment data, a code segment and the data size and address range of the data segment; sending the code segment data, the data segment data, the code segment and the data size and the address range of the data segment to a lower computer; and the lower computer performs partition flashing according to the code segment data, the data segment data, and the data size and address range of the code segment and the data segment. According to the data flashing method provided by the embodiment of the invention, the sizes of the code area and the data area can be automatically adjusted, the flashing program of the lower computer does not need to be frequently upgraded, the subsequent spare part does not execute flashing, and the flashing effectiveness is greatly improved.

Description

technical field [0001] The invention relates to the technical field of data processing, in particular to a method, device, equipment and storage medium for flashing data. Background technique [0002] When updating the program to the target device, the process of updating the program is the process of data flashing. The data flashing speed is usually limited by the baud rate, load rate and the throughput of the gateway for data interaction. The flashing process is relatively slow. long. [0003] With the iterative development of the program, the complexity of the function will continue to increase. If a certain flash memory partition is not enough, it will be re-divided, and the entire partition structure will need to be adjusted. The upper and lower computers will re-upgrade the software, resulting in incompatible software versions. The problem is that it will take a long time to refresh the whole area at the same time. [0004] Therefore, how to improve the efficiency of...
