Abstract

The invention relates to a debugging serial port and data serial port multiplexing method and device and a controller. The debugging serial port and data serial port multiplexing method comprises thefollowing steps: acquiring a serial port type required by a user; comparing the serial port type required by the user with the current type of the serial port; and when the serial port type required by the user is inconsistent with the current type of the serial port, switching the type of the serial port into the serial port type required by the user. According to the invention, under the condition of serial port resource shortage in an embedded system, data serial port and debugging serial port function multiplexing can be realized on one hardware serial port device, i.e., the serial port can be seamlessly switched between the data serial port function and the debugging serial port function simply and quickly; and according to the method, the integrity and correctness of the data on theserial port can be ensured in the switching process of the data serial port function and the debugging serial port function.

Description

technical field [0001] The invention relates to the technical field of computers, in particular to a method, device and controller for multiplexing a debugging serial port and a data serial port. Background technique [0002] Embedded systems are widely used in industrial Internet, intelligent manufacturing, ubiquitous Internet of Things and other fields. Embedded systems are very sensitive to hardware resources due to their cost, size and other limitations. For example, the number of hardware serial devices and network port devices is very limited. Manufacturers of embedded products will maximize the use of hardware devices, such as selecting all hardware serial devices as data serial ports for data transmission. At the same time, debugging through hardware serial devices is the most important and even the only way for embedded Linux developers, testers and system maintainers to develop, test and maintain embedded systems. When all hardware serial ports on an embedded dev...
