Description
Technical field
The present invention relates to a kind of system debug method, particularly a kind of method that is applied to computer system and passes through USB (universal serial bus) (USB) debug.
Background technology
In the flourishing information of science and technology today like flying, the function of information handling system is more and more, then when system's generation problem, the problem of its debug (debug) is corresponding just serious more, though this be system program development phase or system break down can't normal operation in, concerning program development designer or general user, all be very thorny, a headachy problem.
Chance for fear of any may make the mistake (bug), information handling system can normally be moved, for the abnormal occurrence that is produced, must be monitored and then be revised, just be unlikely the serious consequence of the information handling system work that makes a difference, but program development designer in the past or general user, when wrong situation appears in the information handling system running, the reason of the location of mistakes of trying that all must be without any idea, this often must expend a large amount of time and efforts in every particularly.
For addressing the above problem, developed various debugging tools (Debugger), these debugging tools are the implementing procedures that help debug, but this all must purchase expensive device, as hardware emulator (In-Circuit Emulator; ICE), will make that so cost increases substantially; In addition can also be from input/output port (Input/Output port; I/O port) purpose that the decoding circuit reaches debug is set,, connection line must be set in addition, very inconvenience in the use though so cost is lower.
By above-mentioned prior art as can be known, apply to help the implementing procedure of debug at present, not being that to cost an arm and a leg be exactly to use inconvenience, so how a kind of easy debugging tool program that is easy to use and can take into account cost consideration is provided, is one to be badly in need of the technical task that solves in fact.
Summary of the invention
In view of above the deficiencies in the prior art, the invention provides a kind of method of carrying out debug by USB connection system, its purpose is to utilize between remote system (Host PC) and goal systems (Target PC) and is connected USB (universal serial bus) (USB), monitors the work of debug (debug).
Method of carrying out debug by USB connection system of the present invention, with remote system (Host PC) goal systems (Target PC) is carried out debug, debug port (debug port) and program code at first are set in goal systems (Target PC), and monitoring software is set in remote system (Host PC), and then utilize the debug state of the Basic Input or Output System (BIOS) of remote system (Host PC) monitored object system (Target PC), and utilize USB (universal serial bus) (USB interface) linking objective system (Target PC) and remote system (Host PC), to reach the purpose of carrying out debug by USB (universal serial bus) (USB) connected system.

Embodiment
In order to make the present invention more cheer and bright, existing embodiment in conjunction with the accompanying drawings is described in detail as follows.
As shown in Figure 1, this figure is the present invention carries out the method for debug by USB connection system a system construction drawing.
The computer system that connects by USB (universal serial bus) of the present invention comprises goal systems 10 (Target PC) and remote system 20 (Host PC), wherein goal systems 10 is for carrying out the computer system of debug (debug), remote system 20 is then for monitoring the computer system of this debug (debug) information, goal systems 10 comprises: the linkage unit 12 of Basic Input or Output System (BIOS) 11 (BIOS) and goal systems, remote system 20 then comprises: the linkage unit 22 of monitoring debug program 21 and remote system.
Output debug semiotic function at first is set in the Basic Input or Output System (BIOS) 11 (BIOS) of goal systems 10, promptly when the firmware of the Basic Input or Output System (BIOS) 11 of system is made, the program code that to export the debug semiotic function in advance adds in Basic Input or Output System (BIOS) 11 program codes, remote system 20 then is provided with monitoring debug program 21, transmission unit 30 is set between two systems simultaneously connects this goal systems 10 and remote system 20.
Wherein the linkage unit 12 of above-mentioned goal systems is USB (universal serial bus) port (USB port), and the linkage unit 22 of remote system also is a USB (universal serial bus) port, 30 of transmission units are universal serial bus cable (USB cable), and Basic Input or Output System (BIOS) 11 is except being provided with output debug semiotic function, also be provided with flow process controlled flag (flag) and control output debug semiotic function, and this flow process controlled flag value can be set up on their own by the user be 0 or 1, whether continue to carry out monitoring debug program with control.
Do one with regard to debug method of the present invention below and describe in detail, as shown in Figure 2, this figure is the first embodiment process flow diagram of the present invention's method of carrying out debug by USB connection system.
At first drive and be connected running (step 110) with the bus of remote system, read the flow process controlled flag (step 120) of Basic Input or Output System (BIOS), and judge whether to carry out monitoring debug program (step 130), do not carry out monitoring debug program if the flow process controlled flag is shown as, then do not add the program code of output debug semiotic function in the program compiler of the Basic Input or Output System (BIOS) of goal systems (Compiler); If the flow process controlled flag is shown as the monitoring debug program of carrying out, then the debug signal is compiled to data of input/output system content (step 140) by goal systems, and data content is sent to remote system (step 150) by bus, again data content is shown (step 160) in remote system at last, for the debug state of user in the Basic Input or Output System (BIOS) of remote system monitored object system.
The present invention also proposes another embodiment in addition to the implementation, does one with regard to the second embodiment of the present invention below and describes in detail, and as shown in Figure 3, this figure is the process flow diagram of second embodiment of the present invention's method of carrying out debug by USB connection system.
At first compile the debug signal and drive bus and connect running (step 170), confirm flow process controlled flag (step 180) by goal systems then, to judge whether to carry out monitoring debug program (step 130), the flow process controlled flag and be shown as and do not carry out monitoring debug program, then goal systems is not exported the debug signal to remote system; If the flow process controlled flag is shown as the monitoring debug program of carrying out, then the debug signal is spread out of by goal systems, and read the data of input/output system content (step 190) that to export by goal systems, comprised the debug signal in this data content, and data content is sent to remote system (step 150) by bus interface, this bus interface is a USB (universal serial bus) (USBinterface), again data content is shown (step 160) in remote system at last, for the debug state of user in the Basic Input or Output System (BIOS) of remote system monitored object system.
The Basic Input or Output System (BIOS) of above-mentioned two embodiment (BIOS) also has the USB controller of this goal systems (USB controller) initialization (initialize), and by the function of USB (universal serial bus) port (USB port) output data content to remote system.
Use technology disclosed in this invention, can make goal systems only can carry out debug work by a universal serial bus cable (USB cable), make computer system not need as existing system for helping the implementing procedure of debug purchasing price costliness, and make the work of system's debug more have effectively.
The above only is the detailed description of the preferred embodiment of the present invention, still, is not in order to limit practical range of the present invention.Protection scope of the present invention should be as the criterion with the scope that accompanying claims define, and all embodiments that meets the spirit variation similar with it of claims of the present invention all should be included in the category of the present invention.
