Embedded software debugging method

Abstract

The invention discloses a software debugging method based on an embedded type. PC tool software (K-Stack) which is independently compiled reads an embedded elf file which corresponds to a binary codeoperated by the equipment and contains debugging information, reads symbol table information and address information according to a standard elf file format, searches a function to which an error instruction position belongs, disassembles the function, displays the function, a line number and an assembly code, and identifies the error instruction position by using a special color; a debugging module is embedded in an independent embedded real-time operating system (RTOS); a command line is embedded in the debugging module, and a variable address can be obtained, checked and modified and even afunction can be called by matching with a PC tool according to a memory address; according to hot key detection based on a serial port, the embedded system generally uses the serial port as input andoutput, and the system can be suspended to enter an RTOS debugging mode; the problems that currently, common embedded debugging is generally based on JTAG hardware debugging, the method is difficultto use on site after system delivery, and debugging is inconvenient when system operation goes wrong are solved.

Description

technical field [0001] The invention belongs to the communication field, and in particular relates to an embedded software debugging method. Background technique [0002] The commonly used embedded debugging is generally based on JTAG hardware debugging. This method is difficult to use on-site after the system is delivered, and it is impossible to connect the JTAG debugging device when the system runs wrong. Ordinary printing-based debugging methods output a large amount of information during normal operation, occupying CPU resources and making it difficult to parse the output information. The debug output device may not be connected when the delivery environment fails and relevant information may be missed. However, after problems occur due to different operating environments and parameters, some fault points are also difficult to reproduce. As a result, a lot of manpower and time are consumed in the development phase and delivery maintenance. [0003] This technology co...
