Abstract

The present invention is applicable to the technical field of mobile terminals, and provides a system abnormality processing method and device for a mobile terminal, including: monitoring whether there is an abnormality in the subsystem of the mobile terminal through a watchdog; If there is an exception, report the exception to the application processor of the mobile terminal; the application processor sends a restart instruction to the subsystem to restart the subsystem. The invention can constantly monitor and find the abnormal condition of the sub-system of the mobile terminal in real time, and automatically realize the restart of the sub-system, thereby ensuring the timeliness of handling the abnormal condition of the mobile terminal system.

Description

technical field [0001] The invention belongs to the technical field of mobile terminals, and in particular relates to a method and device for handling system exceptions of a mobile terminal. Background technique [0002] With the development of embedded technology, the functions of mobile terminals based on embedded systems are becoming more and more powerful. It is designed as a distributed architecture composed of multi-processors. The corresponding embedded systems are also becoming larger and more complex, and at the same time there are A wide variety of subsystems. [0003] During the operation of the mobile terminal, there may be abnormalities in a certain subsystem, for example, the communication subsystem has no service, the sound subsystem has no sound, or the sensor subsystem fails, etc. Usually, system-level problems cannot be resolved by restoring parameters. The repair can only be solved by restarting the system. However, users are often unaware of the failure ...
