An embedded terminals remote online development system is divided into three parts: an embedded terminal, a cloud forwarding platform and an IDE. Under remote online development, the cloud forwarding platform establishes a communication connection with the IDE through the Internet and establishes a connection with a communication module of the embedded terminal through a communication base station, so that the communication between the IDE and embedded terminal is completed. To be compatible with a local development mode, it is also possible to establish a connection between the IDE and the embedded terminal in a wired manner such as serial communication, to realize local online development. The embedded terminals remote online development system with good universality and flexibility is established in combination with a cloud platform, so the development difficulty of embedded terminals is lowered, repetitive work during development is reduced, development cycle is shortened, and development cost is reduced.

A remote software debugging method for embedded terminals makes it possible to reduce additional hardware dependencies and storage space occupation based on a CoreSight debugging framework and a dynamic command system. Series communication is used as a lead study to reduce the pre-exploration difficulty of complex communication modules and facilitate subsequent extraction of the commonalities of the communication modules. An FPB (flash patch and breakpoint) unit in CoreSight debugging framework provides a basis for setting and responding to breakpoints, debugging information for the breakpoints can be extracted and output by debug monitoring exceptions, and dynamic commands are used as carriers of overall functions to fulfill rich debugging functions such as starting and exiting of a debugging mode, setting and cancelling of breakpoints and control over program running state. Finally, common elements of communication modules are extracted, and a general method for adaptive software debugging of communication modules is provided.
