Problems solved by technology

[0003] In the past, visual debugging can only periodically display the current running value of the device side, and does not have the breakpoint debugging function. It is necessary to provide an efficient implementation method for the logic breakpoint debugging function of the embedded system to improve debugging and development efficiency.

Embodiment Construction

[0020] Such as figure 1 As shown, the present invention provides a kind of debugging method of embedded system, comprises the steps:

[0021] (1) Setting and deleting of controller breakpoints by configuration tools

[0022] In the debug running state, the configuration tool can set a breakpoint on the algorithm module in the logic page, that is, a logic break will occur when the program runs to the algorithm module, and the configuration tool also has the function of deleting the breakpoint. The operations of setting and deleting breakpoints will send instructions to the controller, and the controller will set or delete breakpoint information in the locally maintained breakpoint table after receiving the instructions. When the controller is debugging and running, the breakpoints in the breakpoint table will be hit one by one by default.

[0023] Among them, the breakpoint table information is subject to the content stored in the controller. Whether the breakpoint informatio...

Abstract

The invention discloses a debugging method of an embedded system. Firstly, a configuration tool sets a breakpoint. The configuration tool control controller enters the debugging and running stage; theconfiguration tool sends instructions to the controller for the next operation mode. After the debugging, the configuration tool sends a stop debugging instruction to the controller, which causes thecontroller to end the debugging running state. The debugging method can provide the user to set or delete the breakpoint in the configuration tool, and send the instructions of single-step debugging,page-by-page debugging, module-by-module debugging and continuing execution to the controller through the configuration tool during the debugging process, so as to realize the debugging of the algorithm logic.

Description

technical field [0001] The invention belongs to the technical field of embedded systems, in particular to a debugging method for embedded systems. Background technique [0002] In the embedded control system, it is generally divided into two parts: the upper computer and the lower computer. The upper computer runs the configuration software and is used to write the control program, and the lower computer, the controller, is used to execute the control program. Before the control program written by the configuration software is officially run, it needs to be debugged to check for errors or defects in the program. [0003] In the past, the visual debugging can only display the current running value of the device side periodically, without the breakpoint debugging function. It is necessary to provide an efficient implementation method of the embedded system logic breakpoint debugging function to improve the debugging and development efficiency.
