Abstract

The invention belongs to the field of communication technology and provides a communication interface switching method and device for processors. When a circuit is powered on, a changeover switch corresponding to a preset default processor is controlled to be turned on, and other changeover switches, except the changeover switch corresponding to the preset default processor, are controlled to be turned off; state control information input by a user through a control switch or a first preset processor is acquired; according to the state control information, the changeover switch corresponding to the corresponding processor is controlled to be turned on, and the other changeover switches, except the changeover switch corresponding to the corresponding processor, are controlled to be turned off. Therefore, direct positioning of communication interfaces of the processors through the control switch or the first preset processor is realized; moreover, due to the fact that the communication interfaces of the multiple processors are switched through the changeover switches, cost is saved.

Description

technical field [0001] The invention belongs to the technical field of communication, and in particular relates to a communication interface switching method and device of a processor. Background technique [0002] With the continuous expansion of the functions of the communication equipment, the circuit board (single board) of the existing communication equipment is provided with multiple processors for realizing different functions. Each processor includes at least one communication interface (such as a serial interface, a network interface, etc.), and these communication interfaces are necessary interfaces in the debugging process. However, often limited by the panel or circuit board space, it is not allowed to lead out the communication interface of each processor. [0003] In order to achieve access to each processor while saving panel and circuit board space, a solution provided by the prior art is as figure 1 As shown, an interface connector is set on the circuit bo...
