A software debugging system and method

Abstract

The invention relates to the computer software engineering field and specifically discloses a software debugging system and method. The software debugging system serves as a debugging tool based on the embedded system software and outputs rich debugging information to a debugging host by means of a GPIO (General Purpose Input / Output) simulative general bus interface on a debugging object machine through debugging an agent device; therefore, the debugging efficiency is improved and simple and convenient breakpoint debugging is also realized; and as a result, the software debugging flexibility is improved.

Description

technical field [0001] The invention relates to the field of computer software engineering, in particular to a software debugging system and method. Background technique [0002] In the prior art, the debugging related to the embedded system is based on the system application level (system task level) for debugging communication, that is, under the premise that the embedded system hardware has been driven normally and the corresponding operating system has been running normally For debugging applications, there is no high-efficiency debugging of drivers in the earliest stages of embedded hardware systems. [0003] At present, in the development of embedded systems in the communication industry, it is often necessary to develop embedded systems based on different types of processor platforms and suitable for different operating systems (such as linux, VxWorks, etc.), so it is often necessary to transplant different operating systems to different models However, in the early ...

Problems solved by technology

[0003] At present, in the development of embedded systems in the communication industry, it is often necessary to develop Embedded systems, so it is often necessary to transplant different operating systems to different types of processors, and at the initial stage of debugging the processors, all system communication resources are temporarily unavailable, even resources such as interrupt signals are also unavailable , that is, when the hardware system driver has not been successfully initialized, and there is no corresponding operating system support, it is mainly to link several LED lights on the general purpose input / output (General Purpose Input Output, GPIO) pins, and control the LED lights by operating the processor The light is turned on / off regularly, so as to realize the debugging of the initial driver of the processor; however, because the debugging information conveyed by the above debugging method is not rich enough, the debugging efficiency is low
