Equipment debugging method and electronic equipment

Abstract

The invention provides an equipment debugging method and electronic equipment. The method is applied to the electronic equipment provided with a main CPU, sub-CPUs and a coprocessor, the electronic equipment is provided with a first serial port and a second serial port which are used for external debugging, the first serial port is connected with the main CPU, the second serial port is connected with the coprocessor, and the coprocessor is connected with the sub-CPUs and the main CPU. When a main CPU of the electronic equipment receives a debugging command which is input through a first serial port and aims at a target sub-CPU, a coprocessor is notified to associate a second serial port with the target sub-CPU; and the coprocessor of the electronic equipment outputs the debugging information of the target sub-CPU to the outside through the second serial port after receiving a notification that the main CPU associates the second serial port with the target sub-CPU. The two serial ports are respectively arranged to realize command receiving and information output functions, so that the problem that the whole machine must be restarted due to the fact that commands cannot be received and debugging cannot be continued after the serial ports are switched to the fault sub-CPU in the prior art is solved, and the equipment debugging efficiency is improved.

Description

technical field [0001] One or more embodiments of this specification relate to the field of computer technology, and in particular, to a device debugging method and an electronic device. Background technique [0002] With the development of technology and the improvement of demand, more and more devices adopt the distributed management architecture. Under this architecture, in addition to the main CPU in the device, subsystems such as fan modules and the sub-boards assembled are also configured with their own Sub-CPU. When debugging the device of the distributed management architecture, how to obtain the debugging information of the main CPU and the sub-CPU in the device becomes an urgent problem to be solved. [0003] In related technologies, generally, an external debugging serial port is configured on the device, the serial port is connected to a coprocessor, and the coprocessor is connected to debugging interfaces of all CPUs. The debugger issues a switching command to...

AI Technical Summary

Problems solved by technology

For example, when a switching command for any target CPU is input to the coprocessor through the serial port, if the target CPU is not faulty, the debugging information of the target CPU can be output through the serial port; When the target CPU fails, the debugging information cannot be output through the serial port and the switching command input by the debugging personnel can no longer be received, and if it is necessary to continue to output the debugging information of other CPUs, it is necessary to restart the whole machine to continue the above-mentioned Debugging process

Therefore, it greatly interferes with the work of debugging personnel and reduces the efficiency of equipment debugging
