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 in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0024] In the embodiment of the present invention, the debugger detects the processor type of the target machine through the detection program, and obtains the debugging firmware suitable for the processor type of the target machine according to the processor type of the target machine, and receives and parses the target machine through the debugging firmware. The debugging command sent by the host computer, and the debugging command is sent to the target machine to control the debugging of the target machine.

Abstract

The invention is applicable to the field of system debugging and provides a debugger, a cross debugging system and a method, the debugger comprises a first interface unit, a microcontroller unit and a second interface unit; the first interface unit is used for receiving a detection program and / or a debugging firmware and a debugging instruction and outputting debugging results or detection results and the debugging results; the microcontroller unit is connected with the first interface unit and is used for running the detection program, detecting the type of a processor of a target machine by the detection program, obtaining the debugging firmware which is suitable for the type of the processor of the target machine, running the debugging firmware and converting the debugging instruction received by the first interface unit into a JTAG instruction through the debugging firmware; and the second interface unit is connected with the microcontroller unit and is used for sending the JTAG instruction of the microcontroller unit and receiving the debugging results. As corresponding debugging firmware is adopted according to the type of the processor of the target machine to debug the target machine, target machines of processors of different types can be conveniently and rapidly debugged and tested.

Description

technical field [0001] The invention belongs to the field of system debugging, and in particular relates to a cross debugging system, method and debugger. Background technique [0002] The cross-debugging system is a distributed system, which is mainly used in processors supporting JTAG (Joint Test Action Group, joint test action organization, also known as the international standard test protocol). Among them, the JTAG standard is used to test the access port, and the method of boundary scan is used to test the printed circuit board. It includes host machine, debugger and target machine. The host machine is mainly used to run the debugging software, and the target machine is mainly used for the program to be debugged. The debugging software in the host machine obtains the processor information of the target machine through the debugger, and controls the target machine so as to run on the target machine. The program to be debugged is debugged. It can be used for debugging...
