Embodiment Construction

[0023] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described below in conjunction with the accompanying drawings.

[0024] Such as figure 1 As shown, an embedded software debugging device based on record playback technology includes at least two host computers and at least one target computer, and the host computers all include debuggers, and the debugger of one of the host computers is used as the main debugger. That is the meaning expressed by "master debugger * 1" in the figure, and the debuggers of the other hosts are used as slave debuggers, that is, the meaning expressed by "master debugger *n" in the figure, n is a natural number, and it is characterized in that , the host machine and the target machine are connected and communicated through a server,

[0025] The host machine including the main debugger communicates with the target machine through the server to master the main d...

Abstract

The invention relates to a record playback technology-based embedded software debugging device and method. The device comprises at least one host and at least one target, the hosts comprise debuggers, the debugger of one host is used as a master debugger, and the debuggers of the rest hosts are used as slave debuggers. According to the device and the method, a recording module for recording the debugging process and generating recording data is added at the target. A recording module, namely a server module for storing and managing debugging recording data is increased by the host and the target. The debuggers of the other hosts can play back the debugging process through debugging recording files on a debugging server and can reproduce the running process of a program so as to fulfill the purpose of reproducing an embedded debugging process and performing multi-machine shared debugging.

Description

technical field [0001] The invention belongs to the technical field of computer embedded technology, in particular to the technical field of debugging embedded software. Background technique [0002] Embedded system is an application-centric, computer-based computer system with tailorable software and hardware, which meets the strict requirements of the application system on function, reliability, cost, volume, and power consumption. Embedded systems are generally composed of four parts: embedded microprocessors, peripheral hardware devices, embedded operating systems, and user applications. Embedded operating systems and user applications are all embedded software. Embedded software is software based on embedded system design. It is also a kind of computer software and can be subdivided into three categories: system software, support software, and application software. Embedded software is an important part of embedded systems. Because embedded systems have the characteri...
