Method for debugging embedded type program

Abstract

The invention provides a method for debugging an embedded program. The method establishes communication software through insertion of a break point between a debugger host computer and the debugged program to take over exception handling and partial interrupt handling of a target system and realizes debugging of the embedded application program through insertion of a debugging port communication module into the communication software to interact with a debugger of a PC host computer. The method can be applied in debugging application programs which are operated on the target operating system, and is suitable for terminals provided with embedded systems and application programs such as a tax-control cash register, a financing tax-control cash register, a financing POS machine, a hand-held terminal and so on.

Description

technical field [0001] The invention relates to a computer application technology, in particular to an embedded application debugging method for establishing communication by inserting breakpoints between a debugger (host) and a program to be debugged. Background technique [0002] Debugging is an indispensable link in the development process, and there is a huge difference in the debugging environment between the general PC operating system and the embedded operating system. Among them, the debugging tool based on the PC operating system and the program being debugged are usually two processes running on the same device and the same operating system, and the debugger process controls and accesses the debugged process through the calling interface specially provided by the operating system. Embedded operating system debugging is also called remote debugging, and the debugger can be performed by the embedded device itself based on a specific hardware platform or by the applic...

Problems solved by technology

[0003] For the debugging of embedded programs, the following problems are faced: how to communicate between the debugger and the debugged program, how to notify the debugger in time when the debugged program generates exceptions, how the debugger controls and accesses the debugged program, and how to identify information about the debugged program Data information and real-time viewing, how the debugger handles certain information related to the target hardware platform, etc.
