Abstract

The invention discloses a fault diagnosis file acquisition method and device, and the method comprises the steps: generating a fault diagnosis file and storing the fault diagnosis file in a storage region of a volatile memory after an operation system of terminal equipment is abnormal, and after the terminal equipment is not powered off and restarted, the fault diagnosis file in the storage area of the volatile memory is transferred to a log partition in the nonvolatile memory, and after the terminal equipment is powered off and restarted, the fault diagnosis file in the log partition is transferred to a data partition in the nonvolatile memory. After the terminal equipment is powered off and restarted, the fault diagnosis file in the log partition cannot be lost, further, after the fault diagnosis file in the log partition is transferred to the data partition in the nonvolatile memory, the fault diagnosis file can be directly accessed and acquired, and then the acquisition of the fault diagnosis file is relatively simple.

Description

technical field [0001] The embodiments of the present application relate to the technical field of terminal equipment, and in particular to a method and device for acquiring a fault diagnosis file. Background technique [0002] When the operating system of a terminal device (such as a mobile phone, etc.) is abnormal (such as crashing, etc.) during normal operation, the terminal device will generate a fault diagnosis file and save the fault diagnosis file in a double-rate synchronous DRAM (Double Data Rate In Synchronous Dynamic Random Access Memory, DDR), wherein, the fault diagnosis file includes a fault log and a fault auxiliary diagnosis log, the fault log is used to reflect the abnormal information of the operating system, and the fault auxiliary diagnosis log is used to reflect the abnormal positioning information of the operating system . The fault diagnosis file is an important basis for fault analysis of the operating system, and it is necessary to obtain the fault ...
