Abstract

The invention discloses an application program debugging method under an embedded multi-core environment, and belongs to application program debugging methods. The application program debugging method solves the problems that an existing debugging method cannot be independent from an operation system, is not applicable to debugging when more than two cores exist and is not comprehensive enough in function. The application program debugging method under the embedded multi-core environment comprises the steps of remote connection establishing, debugging instruction sending, debugging instruction analyzing, thread core binding, breakpoint inserting, breakpoint inquiring, breakpoint deleting, single-step executing, continuous execution, execution until ending, variable checking, thread operation core checking, core operation thread obtaining and thread operation time counting. The application program debugging method under the embedded multi-core environment can be independent from the operation system and an embedded development tool to conduct debugging on application programs and is comprehensive in debugging function, a debugger at the end of a host machine can know about the basic conditions of application program running and more accurately locate various abnormal conditions of application program running, and the application program debugging efficiency is improved.

Description

technical field [0001] The invention belongs to a method for debugging an application program of a computer, and in particular relates to a method for debugging an application program in an embedded multi-core environment. Background technique [0002] With the expansion of application requirements and the continuous advancement of technology, it is becoming more and more difficult to improve the performance of single-core processors. It is difficult for single-core embedded architectures to meet the corresponding processing requirements. Multi-core technology is an inevitable trend in the development of processors and is widely used in automobiles. , communications, information appliances, medical, military and other industries of intelligent equipment. Multi-core technology brings higher processor performance, higher power utilization efficiency and smaller physical memory volume for embedded devices, but also significantly increases the complexity of embedded systems. In...
