Abstract: Disclosed are a method, a device, and a computer readable storage medium for detecting and processing a system fault. The method includes: an interrupt service routine sending a first stage kicking dog signal, and receiving a second stage kicking dog signal for a system detection task (S101); and when task dead loop or task abnormity is detected, performing system abnormity processing according to a preset processing policy, wherein when the interrupt service routine fails to receive the second stage kicking dog signal within a set period of time, the interrupt service routine stops sending the first stage kicking dog signal, and the system reboots (S102).

Abstract: Provided is a method for running a version file, including: a file system type of a current file system in a flash is identified in system boot loader software, and the file system is initialized according to the file system type; a file system type supported by a version file to be run is acquired; whether the current file system supports the version file to be run is judged, and if Yes, the version file to be run is run; otherwise, all files in the file system are read and stored in a memory and/or a storage area, not managed by the file system, in the flash, the file system is formatted, the file system is reinitialized according to the file system type supported by the version file to be run, the stored files are stored in the file system, and the version file to be run is run.
