Mobile phone and method for outputting kernel message

摘要

A mobile phone and a method for outputting a kernel debugging message are provided. The mobile phone comprises an audio jack, a level converter, an audio chip, a multiplexer and a central process unit (CPU). The level converter converts a voltage level of the first kernel debugging message to output a second kernel debugging message. The multiplexer comprises an output port, a first input port and a second input port. The output port is connected to the audio jack. The first input port is connected to the level converter. The second input port is connected to the audio chip. After receiving a debugging message output command, the CPU controls the output port to be electrically connected to the first input port to output the second kernel debugging message to the audio jack according to the debugging message output command.
