Abstract
The invention relates to the field of embedded systems, and provides a debugging method with what it is only needed that data interfaces are maintained on a processor, dependence on the development of processors and debugging tools is reduced, and development efficiency is improved.
Description
Technical field
The present invention relates to embedded system field, particularly relate to a kind of adjustment method of only service data interface on a processor.
Background technology
The debugging of usual embedded system, based on request à response modes, is namely completed by the debugging acid be positioned in debug host and the processor be positioned on board or equipment as follows:
It is the request command of A that debugging acid sends appointment data interface format to processor;
Processor is after receiving request command, and sending appointment data interface format to debugging acid is the data of B;
Debugging acid, receiving after data-interface form is the data of B, is undertaken resolving and presenting by form B.
In the debugging model of the appointment data interface shown in Fig. 2, if processor Update Table interface, then need commissioning tool to modify corresponding data-interface, then this time revised by processor and commissioning tool mutual authentication again.Its flow process is as follows:
Step S21: Update Table interface on a processor;
Step S22: Update Table interface on debugging acid;
Step S23: the data-interface revised by debugging acid and processor mutual authentication;
Step S24: be verified rear issue amendment.
There are the following problems for above-mentioned adjustment method:
Need processor and debugging acid jointly to safeguard corresponding data-interface, add development constraints, and when the quantity of data-interface is larger, also can increase the conforming maintenance workload of data-interface;
After processor is modified to data-interface, also must carry out corresponding modify by debugging acid, and need two sides jointly to verify, add the workload of exploitation, also reduce development efficiency.
For the problems referred to above, the present invention proposes one embedded systems debugging method more flexibly, only need service data interface on a processor, decrease the dependence that processor and debugging acid are developed, improve development efficiency.
Summary of the invention
For solving the above-mentioned problems in the prior art, embodiments provide a kind of embedded systems debugging method, method comprises:
Software module on processor, by calling data interface registration function, to debugging proxy log-on data interface, and carries out record by debugging proxy;
Debugging acid, before obtaining the data-interface on processor, needs to establish a communications link with processor;
Debugging acid to processor transmitting order to lower levels, request processor uploading data interface list;
Current chartered data-interface is sent to debugging acid by debugging proxy on processor continuously, is presented in the form of a list on software by debugging acid;
After the user of debugging acid selects certain data-interface on software interface, debugging acid transmitting order to lower levels, to the data-interface content that processor request is concrete;
The content of data-interface and additional information thereof are uploaded to testing tool by set form by processor;
Debugging acid carries out Data Analysis by the data-interface received and presents;
Debugging proxy have recorded all registered data-interfaces, for each data-interface generates an only ID;
Debugging proxy have recorded following information, comprising:
Module title belonging to data-interface;
The generating function entrance of data-interface;
The attribute of data-interface;
The parameter of data-interface: the type of descriptor, information, parameter and storage width.
In the generating function of data-interface, use form, tree structure, or the combination of form and tree structure, generate complicated data-interface.
It is empty data structure that data-interface creates a data content in internal memory, and records the descriptor of this structure, comprises the container level of structure, the quantity of row, the title of row, descriptor, storage width, data pointer.
The commissioning tool debugging proxy stored on data-interface title and processor is the only ID that it distributes, commissioning tool mainly specifies this ID in the order of request msg interface, thus in the debugging proxy of processor, call corresponding data-interface generating function.
The data content of data-interface generating function more in new construction, and whole data structure is uploaded to commissioning tool, presented by commissioning tool.
The embodiment of the present invention, adopts a kind of the method needing service data interface on a processor, provides one embedded systems debugging method more flexibly, decreases the dependence that processor and debugging acid are developed, improves development efficiency.

Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, be clearly and completely described the technical scheme in the embodiment of the present invention, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.
Fig. 4, be the schematic flow sheet of the first embodiment of a kind of embedded systems debugging method of the present invention, the method comprises:
Step S11: the software module on processor is to debugging proxy log-on data interface.
In this step, the debugging proxy that the software on processor runs on processor registers its data-interface, by the following information of debugging proxy record:
Module title belonging to data-interface;
The generating function entrance of data-interface;
The attribute of data-interface;
The parameter of data-interface: as type and the storage width of descriptor, information, parameter;
Debugging proxy have recorded all registered data-interfaces, for each data-interface generates an only ID.
Step S12: debugging acid and processor connect.
In this step, the debugging proxy on debugging acid and processor sets up the connection of data communication, and the communication mode of connection can be diversified, as Ethernet.
Step S13: debugging acid is to processor request msg interface list.
In this step, debugging acid is to the debugging proxy data query interface list on processor.
Step S14: processor uploading data interface list.
In this step, after the debugging proxy on processor receives the inquiry request from debugging acid, by debugging interface information-reply chartered on processor to debugging acid;
The information that described debugging proxy is replied comprises the descriptor of data-interface, information, the type of parameter and storage width.
Step S15: the data-interface content that debugging acid request is specified.
