Problems solved by technology

Once a network delay occurs in the transmission network, it will cause the MCU to receive data overtime, which may cause software upgrade failure; or, although there is no network delay, when the program file data is delivered, the MCU is processing high-priority tasks, resulting in delayed reception. It is considered that the MCU receiving timeout will also cause the software upgrade to fail

Abstract

The embodiment of the invention provides a vehicle-mounted terminal micro-control unit software upgrading method, electronic equipment and a storage medium. The method comprises the following steps of: receiving a first instruction, verifying the first instruction, and determining to upgrade software installed in a vehicle-mounted terminal micro-control unit after the first instruction passes verification; in an idle time period, sending a second instruction to a vehicle-mounted terminal main processor; after a data sub-package of a software upgrading data package is received within a preset time interval, verifying and storing the data sub-package; judging whether the software upgrading data packet is received completely or not, if not, updating the offset, then re-executing the step of sending the second instruction, and if yes, executing the step of sending a third instruction; sending a third instruction to the main processor; and receiving a fourth instruction, restarting to enterthe bootloader according to the time specified by the fourth instruction, and completing upgrading and updating of the software.

Description

technical field [0001] The invention relates to the technical field of vehicle equipment, in particular to a method for upgrading software of a micro control unit of a vehicle terminal, electronic equipment and a storage medium. Background technique [0002] As one of the three major components of the Internet of Vehicles system, the vehicle-mounted terminal is responsible for collecting real-time operating data of the vehicle, and realizing the collection, storage and transmission of all working information and static and dynamic information of the vehicle. [0003] Vehicle-mounted terminals generally include a main processor and an MCU (Microcontroller Unit, Micro Control Unit). The MCU is mainly responsible for real-time processing, such as IO (input output) detection. [0004] The software in the MCU needs to be upgraded. In the prior art, there are mainly two methods for upgrading the software in the MCU: [0005] Method 1: The main processor sends an upgrade instruct...
