Abstract

The invention provides a data processing method and device and a storage medium, and the method is applied to an electronic control unit (ECU), and comprises the steps: receiving a modification instruction sent by an upper computer, the modification instruction comprising modification information of to-be-modified data; according to the modification information, modifying the to-be-modified data pre-mapped to a random access memory (RAM) area of the ECU to obtain modified data; and writting the data block containing the modified data into a flash memory of the ECU. According to the data processing method provided by the embodiment of the invention, the data transmitted by the upper computer can be reduced, so that the data flashing efficiency is improved.

Description

technical field [0001] The present invention relates to the technical field of communication, and in particular to a data processing method, device and storage medium. Background technique [0002] Electronic Control Unit (ECU for short), also known as "driving computer", "vehicle computer" and so on. In terms of use, it is a special microcomputer controller for automobiles. ECU data flashing, also known as flashing ECU, flashing car computer board, and controller flashing, has three main applications: one is to encapsulate data when the engine / car is off the assembly line, and the other is to update and repair the ECU at the car repair station. The third is the application of engine modification. [0003] In the prior art, if there is data that needs to be modified in the Hex or S19 file, the upper computer obtains the address range of all the data in the block where the data needs to be modified in the Hex or S19 file, and modifies the part that needs to be modified , a...
