Abstract

The embodiment of the invention discloses first electronic equipment. The first electronic equipment comprises a processing module, a selection module, a nonvolatile switch and a USB interface, the processing module comprises a serial signal pin and a USB pin. The first input end of the selection module is connected with the serial signal pin, and the second input end of the selection module is connected with the USB pin; the output end of the selection module is connected with the USB interface; the nonvolatile switch is connected between the processing module and the selection module; the nonvolatile switch is used for sending a control signal to the selection module; the selection module is used for switching the on-off state of the selection module on the basis of the control signal soas to conduct the first connection or conduct the second connection; wherein the first connection is used for transmitting serial signals, and the second connection is used for transmitting USB signals.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to an information processing method and electronic equipment. Background technique [0002] At present, electronic devices (such as mobile phones) generally use a command-line tool (for example, logcat) to record the system operation log (log) and output it through a Universal Serial Bus (Universal Serial Bus, USB) interface, so as to analyze and locate the operating time of the device. Vulnerabilities (Bugs). However, command-line tools are more effective for analyzing the vulnerabilities of the application layer, and are often powerless for analyzing the vulnerabilities related to the underlying hardware of the system. For example, when an electronic device crashes or restarts, command-line tools often cannot provide effective logs to locate and analyze vulnerabilities. Contents of the invention [0003] In view of this, an embodiment of the present invention pr...
