Description
Technical field
The present invention relates to communication technical field, particularly a kind of adjustment method, debugging conversion equipment and system of embedded system.
Background technology
Embedded system is normally towards application-specific, and it requires very strict to the execution sequence of logic and execution time.Embedded system is applicable to the strict dedicated system of function, reliability, cost, volume, power consumption requirements.Software development for embedded system is also different from general application software, the former requires that the hardware of developer to embedded system has enough understandings, the software developing a good embedded system is very difficult, is therefore necessary very much the debugger of applicable embedded system.
Existing embedded type debugging mode mainly contains two kinds of modes: one is on-line debugging, and another is off-line debugging.
The scheme of the on-line debugging of embedded system is usually as follows: dispose debugger service end on embedded board (that is: Target Board), dispose debugger client at PC(personalcomputer, personal computer) on, client and service end are by the expanding channels such as network interface or serial ports.Service end is responsible for the resource of access or control embedded system (such as, internal memory, register etc.), client on PC is responsible for accepting the order input of user, carries out command analysis, Debugging message resolves and the real-time/non-real time analysis of debugged program, and the output of Commissioning Analysis result etc.
On-line debugging comprises again non real-time debud mode (that is: stop debud mode), real-time debug mode (that is: non-stop debud mode).Stop debud mode needs first by debugged program stopped, then the information of routine analyzer and state.Non-stop debud mode then can the related status information etc. of Real-time Obtaining program.These two kinds of on-line debugging modes all existing defects, specific as follows:
(1) if the disconnecting of the client of certain moment debugger and the service end of Target Board, then program occurs abnormal.At this moment because the client of debugger cannot obtain the real-time condition of debugged program, the also state of uncontrollable debugged program, causes on-line debugging mode to lose efficacy.
(2), because the exception of program has randomness and non-reproducibility usually, cause the reproduction difficulty of such problem comparatively large, the inefficacy of on-line debugging reduces causing the efficiency of positioning problems and analysis.
, because test process completes at Target Board, there is not the connection between Target Board and debugger in the scheme of off-line test; Therefore can avoid above-mentioned technological deficiency, the scheme of off-line debugging is usually as follows: 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.; Target Board is the acquisition Debugging message of off-line and the dump file of above-mentioned backup on debugger, then analyzes program exception reason.But also there is following defect in off-line debugging:
The platform run due to Target Board is of a great variety, and comprise operating system and the relevant information of Target Board platform in the dump file of backup, the dump file therefore backed up there are differences on form.In addition, in the systemic software development stage of Target Board, the edition upgrading of this system software is usually very fast, but the dump file form corresponding to different editions system software there are differences again.Therefore, debugger client is realizing the dump file supporting different platform, or supports the dump file of same platform different editions, then need to change in a large number debugger client.Like this, in order to solve debugger client and the contradiction of platform on file layout is supported, still need amendment debugger client, and often revise debugger and need a large amount of manpowers and time.
In sum, off-line debugging constantly revises debugger client to realize off-line debugging due to needs, and the difficulty causing realizing off-line analysis is comparatively large, cost is higher, the time is long.In addition, the debugging acid of on-line debugging and off-line debugging needs to develop respectively, there is the problem of overlapping development.

Following examples form with regard to structure respectively, debug networking, source code changes and the scheme of angle to above embodiment of example illustrates in more detail.
One, structure composition
Refer to and Figure 2 shows that: by source-to-source translation, generate the modular structure schematic diagram of off-line order, wherein the direction of arrow is data flow.
For the online of embedded system development and off-line debugger can use C as programming language in this example.On-line debugging order source code (mainly .c and .h file) is as the input source of off-line command converter.
Off-line command converter mainly contains three parts: symbol resolution module, dump file parsing module and source-to-source translation module.
Symbol resolution module obtains definition and the address mapping table of globak symbol from input source, and the denotational description information relevant to business, after carrying out symbol resolution and processing, outputs to source-to-source translation module.
Another input of source-to-source translation module is from dump file parsing module, dump file parsing module mainly completes the analysis and treament to off-line files register and call stack rule, this part ISA(IndustrialStandardArchitecture that is usual and embedded system, industrial standard architecture bus) strong correlation.
Just can be completed the output of last off-line debug command source code (mainly .c and .h file) by the inner rule defined after source-to-source translation module gets the information of needs.Off-line debugger now has been provided with the business related symbol table information and address information that in-circuit debugger module has, and uses the printing interface of off-line debugger just can obtain product service related information.
Two, networking is debugged
Typical debugger networking schematic diagram as shown in Figure 3,
Under on-line debugging scene, be positioned at PC(personalcomputer, personal computer) the debugger client of holding and the debugging services end that is positioned on Target Board (Board) by ETH(Ethernet, network interface) or the passage such as serial ports communicate.Wherein also include IDE(IntegratedDevelopmentEnvironment in PC side, Integrated Development Environment), application program, system and internal memory/register is also included in Board side.
Under off-line debugging scenarios, register/memory information, operation system information or product business information required for debugger client is obtained from the dump file (CoreFileonPC) of PC by file I/O.
Three, source code conversion
Referring to Fig. 4 is: online order converts the schematic flow sheet of off-line order to.
401: formulate the transformation rule that on-line debugging order smooths to off-line debug command;
On-line debugging order has the rule of complete set to the conversion of off-line order.The customization of rule mainly can comprise following a few part: symbol table information transformation rule, main formulates the rule address mapping information of on-line debugging order business related symbol or globak symbol being transformed into the symbolic information that in-circuit debugger can identify.Register and call stack rule, comprise general-purpose register number, Function return addresses, the register configuration such as stack pointer and PC pointer, and function call stack information etc.Debugging output interface transformation rule, formulates and the command interface of on-line debugging is transformed into off-line debug command interface.Internal memory distribution rule, determines the size and distribution etc. of privately owned internal memory or shared drive.According to the demand of practical business, can 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 be: the source code reading in online debug command, carries out the rule match of character string according to the transformation rule of above-mentioned formulation.If the match is successful, then call conversion process interface and generate the compiler morphology that can identify or syntactic units, then exported the source code of last off-line debug command by compiler.
403: the source code of the off-line debugging had nothing to do together with framework and conversion by the source code of the off-line debug command that will generate in 402, is compiled in and can generates new off-line debugger client together.
Above protocol step 402 and 403 all can adopt other modes to replace, specific as follows:
In above-mentioned schematic flow sheet 4 402 is have employed the source code that the source code of on-line debugging order is converted to off-line debug command by source code conversion compiler.Replacement scheme can not rely on compiler, realizes separately the conversion client instrument that the source code of on-line debugging order is converted to the source code of off-line debug command by.That is crossover tool can depart from compiler, and client utility possesses process of analysis rule map, generates the function of final source code.
In schematic flow sheet 4 402 another kind of replacement schemes are by compiler, and the code (mainly .c and .h file) of the off-line order converted is linked into a dynamic base (.dll or .so form).Secondary compiling so in 403 just can be omitted, and the debugger client of off-line only needs the dynamic base of generation in dynamic load 402 just can complete corresponding debug function.
Four, example
Below a kind of enforcement scene:
Refer to and Figure 5 shows that a source-to-source translation process instance, this example is to inquire about the CPU(CentralProcessingUnit of current system, central processing unit) load factor is example, Fig. 5 adopts C language to write, the related specifications can write with reference to C language, wherein left side one source code that is classified as on-line debugging order, the source code of corresponding with it off-line debug command that what right side arrow was pointed to is, the source code of on-line debugging order is converted to the process of the source code of off-line debug command by this example.Mainly be divided into three steps:
1, the global variable in this order realization is identified.This is the global variable that a business is relevant, is first to have the transformation rule identifying this service symbol.Rule is very simple, identifies the character string (namely in Fig. 5, the boldface letter content gone up most in a dotted line frame in large frame above) in quotation marks.
Off-line command converter constantly reads in input file (i.e. side code on the left of Fig. 5), when recognizing DSP_LkAddr key word, (this is the calling interface of a service inquiry symbolic address, when Rulemaking, can this interface interchange be configured in rule, coupling for character string), off-line command converter matches this key word character string bracketed with double quotation marks below, is exactly gstruCpuLoad in this example.Subsidiary implicit transformation rule is Member call original structure body Member call being converted to recognized character string, as struCpuLoad.uwCurLoad---->gstruCpuLoad.uwC urLoad, this transformation result is using the input as function call translation interface below.Conversion corresponding relation shown in arrow as shown in Figure 5.
2, obtain the function call of global variable value, replace to the function call in off-line debug client end.
As in Fig. 5, convert the calling interface DSP_CommRead of online query business address of variable to corresponding off-line calling interface getSymAddrSize, struCpuLoad.uwCurLoad---->gstruCpuLoad.uwC urLoad transformation result is above imported into as interface parameters simultaneously.
3, the function call returning results output is ordered to replace to the function call of off-line debug client end.
After the interface conversion that globak symbol and the acquisition overall situation are measured completes, just can realize the conversion of final step platform printout interface, this converted the function achieving last debug results output switching.On-line debugging interface LBB_DSP_Printf in such as this example is transformed into off-line printing interface printf.
Adopt above scheme, because the on-line debugging of built-in system software and off-line debugging are applied to different scenes, and the debud mode that is all absolutely necessary.The embodiment of the present invention realizes the off-line debugging of on-line debugging order, the on-line debugging of built-in system software and the overlapping development problem of off-line debugging can be solved, by the conversion of code that on-line debugging order is carried out debugging from the source code of on-line debugging order to off-line, convert the off-line debug command that can use on PC to, and using symbol resolution power and energy to become address and length the product business information related in order, namely off-line order can obtain system related information by the corresponding memory address interval of inquiry.The off-line debugging realizing on-line debugging order can be avoided realizing off-line debugging to different platforms, or when identical platform being realized to the off-line debugging of different editions, all need to revise the problem of debugger client, therefore, the inventive method can increase the usable range of online debugging acid, shorten the development time of off-line debugging acid, reduce cost of development.
