Description
Technical field
The present invention relates to communication technical field, particularly a kind of adjustment method of embedded system, debugging conversion equipment and system.
Background technology
Embedded system is normally towards application-specific, and it requires very strict to the execution sequence and the execution time of logic.Embedded system is applicable to function, reliability, cost, volume, the strict dedicated system of power consumption.Software development for embedded system also is different from general application software, the former requires the developer that the hardware of embedded system is had enough understandings, the software of a good embedded system of exploitation is difficulty very, therefore is necessary very much the debugger of suitable embedded system.
Existing embedded type debugging mode mainly contains dual mode: a kind of is on-line debugging, and another is the off-line debugging.
The scheme of the on-line debugging of embedded system is as follows usually: dispose the debugger service end on embedded board (that is: Target Board), dispose the debugger client at PC(personal computer, personal computer) on, client is connected by passages such as network interface or serial ports with service end.Service end be responsible for visiting or controlling embedded system resource (such as, internal memory, register etc.), client on the PC is responsible for accepting user's order input, carries out real-time/non real-time analysis of command analysis, Debugging message parsing and debugged program, and the output of debugging analysis result etc.
On-line debugging comprises non real-time debud mode (that is: stop debud mode) again, real-time debug mode (that is: non-stop debud mode).The Stop debud mode needs earlier debugged program to be stopped, then the information of routine analyzer and state.The non-stop debud mode then can obtain the correlation behavior information of program etc. in real time.All there is defective in these two kinds of on-line debugging modes, and are specific as follows:
(1) if certain constantly client and the Target Board of debugger service end be connected interruptions, then the program appearance is unusually.At this moment because the client of debugger can't be obtained the real-time condition of debugged program, also the state of uncontrollable debugged program causes the on-line debugging mode to lose efficacy.
(2), because program unusual common has randomness and non-reproducibility, cause the reproduction difficulty of such problem greatlyyer, the inefficacy of on-line debugging will cause the efficient reduction of positioning problems and analysis.
Because test process finishes at Target Board, there be not being connected between Target Board and the debugger in the scheme of off-line test; Therefore can avoid above-mentioned technological deficiency, the scheme of off-line debugging is as follows usually: Target Board will comprise the dump file of backup, and the dump file of backup includes register information, memory information and operation system information etc.; The dump file that obtains Debugging message and above-mentioned backup of Target Board off-line on debugger is analyzed the program exception reason then.But also there is following defective in the off-line debugging:
Because the platform of Target Board operation is of a great variety, comprises operating system and the relevant information of Target Board platform in the dump file of backup, therefore the dump file of backup there are differences on form.In addition, in the systemic software development stage of Target Board, the edition upgrading of this system software is very fast usually, yet the dump file form of different editions system software correspondence be there are differences again.Therefore, the debugger client is at the dump file of realizing supporting different platform, or the dump file of support same platform different editions, then needs the debugger client is changed in a large number.Like this,, still need to revise the debugger client, need great amount of manpower and time and often revise debugger in order to solve debugger client and the platform contradiction on file layout is supported.
In sum, off-line debugging is owing to need constantly to revise the debugger client and bring in and realize the off-line debugging, causes realizing that the difficulty of off-line analysis is big, cost is higher, the time is long.In addition, the debugging acid of on-line debugging and off-line debugging needs exploitation respectively, has the problem of overlapping development.

Following examples respectively with regard to structure form, the angle of debugging networking, source code conversion and example illustrates in more detail to the scheme of above embodiment.
One, structure is formed
See also and Figure 2 shows that: by the source-to-source conversion, generate the modular structure synoptic diagram of off-line order, wherein the direction of arrow is data flow.
Can use C as programming language for the online and off-line debugger of embedded system development in this example.On-line debugging order source code (mainly being .c and .h file) is as the input source of off-line command converter.
The off-line command converter mainly contains three parts: symbol resolution module, dump file parsing module and source-to-source modular converter.
The symbol resolution module is obtained the definition and the address mapping table of globak symbol from input source, and the denotational description information relevant with business, after carrying out symbol resolution and handling, outputs to the source-to-source modular converter.
Another input of source-to-source modular converter is from the dump file parsing module, the dump file parsing module is mainly finished analysis and the processing to off-line files register and call stack rule, this part ISA(Industrial Standard Architecture common and embedded system, industrial standard architecture bus) strong correlation.
Just can finish the output of last off-line debug command source code (mainly being .c and .h file) after getting access to the information that needs when the source-to-source modular converter by the rule that inside defines.The off-line debugger of this moment has had professional related symbol table information and address information that the in-circuit debugger module has, uses the printing interface of off-line debugger just can obtain the product service related information.
Two, debugging networking
Typical debugger networking synoptic diagram as shown in Figure 3,
Under the on-line debugging scene, be positioned at PC(personal computer, personal computer) the debugger client of end and be positioned at debugging services end on the Target Board (Board) by ETH(Ethernet, network interface) or passage such as serial ports communicate.Wherein also include IDE(Integrated Development Environment, Integrated Development Environment in the PC side), also include application program, system and internal memory/register in the Board side.
Under the off-line debugging scene, the debugger client is obtained needed register/memory information, operation system information or product business information by file I/O from the dump file (Core File on PC) of PC.
Three, source code conversion
Seeing also Fig. 4 is: online command conversion becomes the schematic flow sheet of off-line order.
401: formulate the transformation rule that the on-line debugging order smooths to the off-line debug command;
The on-line debugging order has the complete rule of a cover to the conversion of off-line order.The customization of rule mainly can comprise following a few part: symbol table information transformation rule, the main rule of formulating the symbolic information that the map addresses information translation of professional related symbol of on-line debugging order or globak symbol can be discerned to in-circuit debugger.Register and call stack rule comprise the general-purpose register number, the function return address, and register configuration such as stack pointer and PC pointer, and function call stack information etc.Debugging output interface transformation rule, the command interface of formulating on-line debugging is transformed into off-line debug command interface.The internal memory distribution rule is determined the size of privately owned internal memory or shared drive and distribution etc.Can be according to the demand of practical business, add or delete some rule.
402: use source code conversion compiler the source code of on-line debugging order to be converted to the source code of off-line debug command;
The ultimate principle of the conversion of this step can for: read in the source code of online debug command, carry out the rule match of character string according to the transformation rule of above-mentioned formulation.If the match is successful, then call the conversion process interface and generate morphology or the syntactic units that compiler can be discerned, export the source code of last off-line debug command again by compiler.
403: the source code by the off-line debug command that will generate in 402 is compiled in and can generates new off-line debugger client together together with the source code of the irrelevant off-line debugging of framework and conversion.
Above scheme step 402 and 403 all can adopt other modes to replace, and is specific as follows:
In the above-mentioned schematic flow sheet 4 402 is to have adopted source code conversion compiler the source code of on-line debugging order to be converted to the source code of off-line debug command.Replacement scheme can not rely on compiler, realizes that separately a source code with the on-line debugging order converts the conversion client instrument of the source code of off-line debug command to.That is to say that crossover tool can break away from compiler, client utility possesses the process of analysis rule map, generates the function of final source code.
402 another kind of replacement schemes in the schematic flow sheet 4 are by compiler, and the code (mainly being .c and .h file) of changing the off-line order of coming out is linked into a dynamic base (.dll or .so form).The compiling of secondary in 403 just can be omitted so, and the debugger client of off-line only needs the dynamic base of generation in the dynamic load 402 just can finish corresponding debug function.
Four, example
Below be a kind of enforcement scene:
See also and Figure 5 shows that a source-to-source transfer process example, this example is to inquire about the CPU(Central Processing Unit of current system, central processing unit) load factor is an example, Fig. 5 adopts the C language compilation, can be with reference to the related specifications of C language compilation, left side one source code of classifying the on-line debugging order as wherein, right side arrow is pointed to is the source code of corresponding with it off-line debug command, this example converts the source code of on-line debugging order to the process of the source code of off-line debug command.Mainly be divided into three steps:
1, identifies this order global variable in realizing.This is the relevant global variable of a business, at first is the transformation rule that will have this service symbol of identification.Rule is very simple, the character string of identification in the quotation marks (be among Fig. 5, most going up a boldface letter content frame of broken lines in the top big frame).
The off-line command converter is constantly read in input file (being Fig. 5 left side side code), (this is the calling interface of a service inquiry symbolic address when recognizing the DSP_LkAddr key word, in Rulemaking, can be configured in this interface interchange in the rule, the coupling that is used for character string), the off-line command converter matches the character string that brackets with double quotation marks of this key word back, is exactly gstruCpuLoad in this example.Subsidiary implicit transformation rule is original structure body member to be called be converted to that the member of identification string calls, as struCpuLoad.uwCurLoad----〉gstruCpuLoad.uwCurLoad, this transformation result will be as the input of following function call translation interface.Conversion corresponding relation shown in the arrow as shown in Figure 5.
2, obtain the function call of global variable value, replace to the function call in the off-line debug client end.
In Fig. 5, converting the calling interface DSP_CommRead of the professional address of variable of online query to corresponding off-line calling interface getSymAddrSize, simultaneously top struCpuLoad.uwCurLoad----〉the gstruCpuLoad.uwCurLoad transformation result imports into as interface parameters.
3, the function call of order return results output replaces to the function call of off-line debug client end.
After globak symbol and the interface conversion of obtaining overall situation amount are finished, just can realize the conversion of final step platform printout interface, this has changed the function that has realized last debug results output switching.Be transformed into off-line printing interface printf such as the on-line debugging interface LBB_DSP_Printf in this example.
Adopt above scheme, debugging is applied to different scenes because the on-line debugging of built-in system software is with off-line, and the debud mode that all is absolutely necessary.The embodiment of the invention realizes the off-line debugging of online debug command, can solve the on-line debugging of built-in system software and the overlapping development problem of off-line debugging, by the on-line debugging order being carried out the conversion of the code of debugging from the source code of on-line debugging order to off-line, convert the off-line debug command that on PC, to use to, and the product business information that will relate in will ordering uses the symbol resolution function to convert address and length to, and the off-line order promptly can be obtained system related information by inquiry corresponding memory addresses interval.Realize that the off-line debugging of online debug command can avoid different Platform Implementation off-line debugging, or all need to revise the problem of debugger client during to the debugging of the off-line of identical Platform Implementation different editions, therefore, the inventive method can increase the usable range of online debugging acid, shorten the development time of off-line debugging acid, reduced cost of development.
