Embodiment
For the purpose, technical scheme and the advantage that make the embodiment of the invention is clearer, specific embodiment is described in detail below in conjunction with accompanying drawing.
The hardware block diagram of verification system as shown in Figure 1, comprise PC (PC) and development board, owing to be checking to file system on the development board, link to each other by the simplest RS232 Serial Port Line between PC and the development board, help simplified system like this, when makeing mistakes, find error reason fast, certainly, between PC and the development board multiple connected mode can be arranged, for example communication, so connected mode includes but not limited to the serial communication mode.
Proving program on the PC is the system of a class DOS, has a plurality of orders, and the tester sends order by the serial ports program, and development board responds after receiving order, carries out certain corresponding program, and the result that will carry out returns to PC then.
PC and development board command response process flow diagram as shown in Figure 2, after PC and development board were all finished system initialization, development board entered wait command state 201, if receive the order of PC, then sent rreturn value after the fill order to PC; PC enters and waits for rreturn value state 211 after sending order to development board, up to receiving rreturn value, like this, has just finished a command response flow process between PC and the development board.
The verification method of the embedded file system that the embodiment of the invention provides is based on above verification system and above command response flow process, and as shown in Figure 3, verification method comprises the steps:
In the described step 303, described operation comprises: inquire about and search for described directory tree.Like this, can realize that directory tree is intuitively simple, need not note down the order of the loaded down with trivial details DOS formula of development board by the directory tree of operating terminal to development board inquiry and search.And, operating terminal can also send catalogue or the file that described file system is revised in order, still, and at the catalogue or the file of each variation, all want corresponding catalogue or the pairing node of file of revising described variation, so that the file system of directory tree and development board is consistent.
In step 301 and step 302, obtaining information and make up the process of directory tree can be with reference to figure 4.
The directory tree transfer process figure that Fig. 4 provides for the embodiment of the invention; PC sends first order later on executing initialization operation, obtains the directory tree of file system on the development board.After development board receives this order, travel through the file system of oneself, whenever traverse a file (comprising root directory), just the information under this catalogue (is comprised file and directory name, but do not comprise darker first class catalogue, add file size, create and revise the date etc. according to application demand) packing, send to PC; The PC tree construction that creates a directory whenever receives a packets of information, resolves and the directory information of correspondence is added in the directory tree structure.
The available mode as shown in Table 1 and Table 2 of directory information bag represents that because file system is all restricted to pathname and filename, some special character codes can not appear at wherein, just can utilize these special characters to do cutting apart between these filenames here.2 these packets of information of byte representation of the beginning of packets of information length (using byte representation) altogether, be subsequently this catalogue correspondence pathname for example/boot/dir, represent ending place in path with separator, be the information of a plurality of files or sub-directory under this catalogue subsequently.
Table 1 directory information bag:
| Total data length (2B) | The routing information of this catalogue correspondence | Separator | Fileinfo | Separator | Fileinfo | ... | CRC check information |
Table 2 fileinfo:
| The file type mark | Filename | File out of Memory (file size, establishment and modification time etc.) |
Development board has just built directory tree after having traveled through local file system above the PC, use view to show on PC, and fileinfo is very clear.When wanting operation file this time, can directly on view, operate, the flow process of system response as shown in Figure 5, the user is by the view of the described directory tree of operation, make operating terminal send catalogue or file that described file system is revised in order, the catalogue of each variation of development board or file are all wanted corresponding catalogue or the pairing node of file of revising described variation, so that the file system of directory tree and development board is consistent, concrete steps comprise:
Step 506 judge to be carried out whether success, is execution in step 507 then, otherwise execution in step 508;
Step 507 provides and carries out unsuccessful prompting, finishes;
Corresponding above method, the embodiment of the invention also provides a kind of demo plant of embedded file system, comprising:
The information acquisition module is used to obtain the directory information of each grade catalogue of embedded file system of development board and the fileinfo of each file;
Make up module, be used to make up directory tree, each of described file system grade catalogue and each file all have node one to one in described directory tree;
Operational module is used for obtaining described directory information and/or described fileinfo by operating described directory tree.
Comprise inquiry and search unit in the described operational module, be used for inquiry and search for described directory tree, also comprise the modification unit, be used to send catalogue or the file that described file system is revised in order, and, at the catalogue or the file of each variation, all corresponding catalogue or the pairing node of file of revising described variation.
As from the foregoing, the embodiment of the invention advantage is a function of search of having accelerated file greatly.Because catalogue and file on each node on the PC in the directory tree and the development board in the file system are one to one, and adjust accordingly according to user's operation, so certain file in the search file system just changes into certain node in the searching directory tree, the speed of traversal directory tree is very fast on PC, and search file need carry out the disk read operation repeatedly in file system, by contrast, the speed of search is improved greatly.
In addition, with the comparison of current programme, the method for present authenticating documents system is to carry out with the form of shell, need a lot of orders of memory, it is convenient inadequately to use, and the embodiment of the invention can offer tester's good interface, operation efficiently, and strengthen function of search.
The above only is a preferred implementation of the present invention; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the principle of the invention; can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
