Embodiment
To understand in order technical characterictic of the present invention, purpose and effect being had more clearly, to contrast accompanying drawing at present and specify embodiment of the present invention.
Seeing also Fig. 1, is the process flow diagram of the method for embedded device program burn writing of the present invention, and this method specifically may further comprise the steps: constructed a kind of method of program burn writing of embedded device, having comprised:
Step 11: will treat that the programming program file is divided into Boot Loader and is stored in all the other the programming files in the SD card;
Step 12: increase and change the Boot Loader code of increasing income, the Boot Loader that will increase after changing goes into embedded device through the cd-rom recorder programming;
In the present embodiment, Boot Loader uses the code VIVI that increases income, and increases the content that changes and comprises: to the support of SD card reading and writing data, compatibility standard SD card and SDHC card reach the parsing to the fat32 file system.Because Boot Loader file is less, when using cd-rom recorder to carry out programming, cause the possibility of programming failure minimum because of bad block occurring.
Step 13: operation Boot loader utility, normal start-up system;
Step 14: judge whether there is the SD card in the current system, if exist, then carry SD card obtains the listed files in the SD card, and gets into following step, otherwise returns step 103;
Wherein, in step 14, when having the SD card in the detected current system, initialization SD card at first; Differentiate the type of SD card, read the data in the SD card by the address, standard SD card is a byte address, and the SDHC card is a block address; And,,, find the first address of file data through filename at first with reference to the form of fat32 file system to the parsing of fat32 file system; Be delivered to SD card module for reading and writing as parameter, and obtain the number of clusters that file takies, confirm whether file runs through.Through the mount order SD card is mounted in the file system then, carries out following step.
Step 15: judge whether to exist in the SD card and treat the programming file,, return step 13,, utilize all the other programming files in the SD card will treat that the programming of programming file goes in the embedded device if exist if do not exist;
Wherein, said all the other programming files comprise kernel image file, root file system image file, root file system bag, application package and programming instrument, and then said step 15) further comprises:
Step 151: start the programming instrument, kernel and root file system image file are copied to the internal memory from the SD card move;
Step 152: the All Files programming is gone among the FLASH of embedded device through kernel, root file system and programming instrument.For kernel, the kernel subregion that can write direct through the interface that kernel mtd provides is for can the root file system subregion being mounted in the file system with file system, then with the literature kit decompress(ion); For application program, can through duplicate, delete command operation realizes.
Step 16: programming removes the SD card after accomplishing, and restarts system.
Based on above-mentioned steps, accomplished through the SD card remaining programming file has been comprised the programming of kernel, root file system, application program, and need not these to be treated that the programming file carries out programming, thereby avoided the programming failure that causes because of bad block through cd-rom recorder.The method of the program burn writing of the embedded device described in the embodiment of the invention is applicable to based on ARM9 and reaches the embedded device with upper mounting plate; In the programming process; Can pass through sound or display reminding based on different embedded devices; Thereby realized man-machine interaction, in the programming process, occurred in time to stop programming unusually, improved programming quality and efficient greatly.
A kind of system of embedded device program burn writing is also disclosed in the embodiment of the invention, as shown in Figure 2, comprise Boot Loader module 1 and programming module 2, wherein Boot Loader module 1 is arranged in embedded system, and programming module 2 is arranged in the SD card.
See also shown in Figure 3ly, be the fundamental diagram of Boot Loader module 1.Boot Loader module 1 is present in the embedded system; The content of module very burning is gone into the Boot Loader in the embedded device, be mainly used in to judge whether current system exists external SD card, and when having the SD card initialization SD card and read the file in the SD card; When having all the other programming files in the file in the SD card; Kernel in the SD card and root file system image file copied in the internal memory move, and start the programming instrument in all the other programming files, to carry out programming.
See also shown in Figure 4ly, be the fundamental diagram of programming module 2.Said programming module is used for behind the programming instrument start-up; Programmings such as kernel, root file system and application program are gone among the FLASH of embedded device; The interface that provides through kernel mtd of the kernel kernel subregion that writes direct wherein, the root file system subregion is mounted in the file system, then with the literature kit decompress(ion) to write file system; And for application program; Can duplicate through the utilization of programming instrument, order such as deletion carries out programming, simultaneously in the programming process through showing or auditory tone cues programming process, to realize man-machine interaction.
The above for the person of ordinary skill of the art, can make other various corresponding changes and distortion according to technical scheme of the present invention and technical conceive, and all these changes and distortion all should belong to the protection domain of claim of the present invention.
