Specific embodiment
For a clearer understanding of the technical characteristics, objects and effects of the present invention, now control attached drawing is described in detail
The specific embodiment of the present invention.
Referring to Fig. 1, it is the flow chart of the method for embedded device program burn writing of the present invention, this method specifically includes following
Step：A kind of method of the program burn writing of embedded device is constructed, including：
Step 11：It will treat that programming program file is divided into Boot Loader and remaining the programming file being stored in SD card；
Step 12：Increasing changes Boot Loader Open Source Codes, and the Boot Loader increased after changing are entered by cd-rom recorder programming
Embedded device；
In the present embodiment, Boot Loader use Open Source Code VIVI, increase the content changed and include：SD card data are read
The support write, compatibility standard SD card and SDHC cards and the parsing to fat32 file system.Due to Boot Loader files compared with
It is small, when cd-rom recorder is used to carry out programming, cause the possibility of programming failure minimum because there is bad block.
Step 13：Run Boot loader utilities, normal activation system；
Step 14：Judge with the presence or absence of SD card in current system, if it is present carry SD card, obtains the text in SD card
Part list, and into following step, otherwise return to step 103；
Wherein, at step 14, when there are during SD card, initialize SD card, discriminating SD first in the current system detected
The type of card reads the data in SD card by address, and standard SD card is byte address, and SDHC cards are block address, and to fat32 texts
The parsing of part system with reference first to the form of fat32 file system, by filename, finds the first address of file data, makees
SD card module for reading and writing is transmitted to for parameter, and obtains the number of clusters of file occupancy, to determine whether file runs through.Then pass through
SD card is mounted in file system by mount orders, to carry out following step.
Step 15：Judge to whether there is in SD card and treat programming file, if it does not, return to step 13, if it does, sharp
It will treat that programming file programming enters in embedded device with remaining programming file in SD card；
Wherein, remaining described programming file includes kernel image file, root file system image file, root file system
Packet, application package and flashburn tools, the then step 15）Further comprise：
Step 151：Start flashburn tools, kernel and root file system image file are copied in memory from SD card and transported
Row；
Step 152：All Files programming is entered into embedded device by kernel, root file system and flashburn tools
In FLASH.For kernel, can kernel subregion be write direct by the interface that kernel mtd is provided, for that can be incited somebody to action with file system
Root file system subregion is mounted in file system, is then decompressed file packet；It, can be by replicating, deleting for application program
Except command operation is realized.
Step 16：After the completion of programming, SD card is removed, restarts system.
Based on above-mentioned steps, completed by SD card and kernel, root file system are included to needed programming file, using journey
The programming of sequence without treating that programming file carries out programming to these by cd-rom recorder, thus is avoided and is burnt caused by bad block
Write failure.The method of the program burn writing of embedded device described in the embodiment of the present invention is suitable for based on ARM9 and with upper mounting plate
Embedded device, during programming, based on different embedded devices can by sound or display reminding, it is achieved thereby that
Human-computer interaction, appearance is abnormal during programming can stop programming in time, substantially increase programming quality and efficiency.
A kind of system of embedded device program burn writing is also disclosed in the embodiment of the present invention, as shown in Fig. 2, including Boot
Loader modules 1 and programming module 2, wherein Boot Loader modules 1 are located in embedded system, and programming module 2 is located at SD card
In.
It please refers to shown in Fig. 3, is the fundamental diagram of Boot Loader modules 1.Boot Loader modules 1 are present in embedding
In embedded system, the content extremely burning of module enters the Boot Loader in embedded device, is mainly used for judging current system
With the presence or absence of external SD card and when there are during SD card initialize SD card and read SD card in file, when the file in SD card
It is middle there are during remaining programming file, the kernel in SD card and root file system image file are copied in memory and run, and is opened
The flashburn tools in remaining programming file are moved, to carry out programming.
It please refers to shown in Fig. 4, is the fundamental diagram of programming module 2.The programming module is used to start in flashburn tools
Afterwards, in the FLASH that the programmings such as kernel, root file system and application program are entered to embedded device, wherein kernel passes through kernel mtd
The interface of offer writes direct kernel subregion, and root file system subregion is mounted in file system, then by file packet decompress with
File system is written, and for application program, can by flashburn tools using replicating, the orders progress programming such as delete, while
By display or auditory tone cues programming process during programming, to realize human-computer interaction.
The above, for those of ordinary skill in the art, can according to the technique and scheme of the present invention and technology
Other various corresponding changes and deformation are made in design, and all these changes and deformation should all belong to the claim of the present invention
Protection domain.
