The application provides a kind of embedded system program method for burn-recording, and the primary processor in embedded system, when receiving burning instruction, reads burning boot from the External memory equipment being connected with described embedded system; Described primary processor moves described burning boot, guiding does not rely on the default burning script operation of kernel and root file system operation, the recordable paper for the treatment of in described External memory equipment is burned onto in the Flash of described embedded system, and described default burning script is stored in described External memory equipment; Wherein, described in, treat that recordable paper at least comprises: for boot Boot Loader, kernel, root file system and the application program of Boot Dernel, root file system operation.Below a kind of embedded system program method for burn-recording of enumerating embodiment the application being provided is described.
An embodiment
Refer to Fig. 1, a kind of process flow diagram that it shows a kind of embedded system program method for burn-recording that the application provides, can comprise the following steps:
Step S11: the primary processor in embedded system, when receiving burning instruction, reads burning boot from the External memory equipment being connected with described embedded system.
In the present embodiment, in embedded system, toggle switch can be set, realize embedded system and start from External memory equipment.Embedded system from External memory equipment start be primary processor embedded system when receiving the burning instruction sending by toggle switch, primary processor reads burning boot from the External memory equipment being connected with embedded system.
Certainly, also can power on to give tacit consent to from the External memory equipment that embedded system connects by embedded system and read burning boot.
Burning boot is used for guiding default burning script.
Wherein, the generative process of burning boot is specifically as follows: first the source code of boot Boot Loader is modified, compiling generates two kinds of binary files, wherein a kind of binary file is burning boot, externally in memory device, start, be used for guiding default burning script, be not used in Boot Dernel and root file system and start; Another binary file can start in Flash, for Boot Dernel and root file system, starts.
Certainly, burning boot can not generate by revising the form of the source code of boot Boot Loader yet, can brand-new boot of direct compilation as burning boot, externally in memory device, start, for guiding default burning script.
Step S12: described primary processor moves described burning boot, guiding does not rely on the default burning script operation of kernel and root file system operation, the recordable paper for the treatment of in described External memory equipment is burned onto in the Flash of described embedded system, and described default burning script is stored in described External memory equipment.
Primary processor after reading burning boot from External memory equipment, and operation burning boot, guides default burning script operation, and the recordable paper for the treatment of in External memory equipment is burned onto in the Flash of described embedded system.
Wherein, the recordable paper for the treatment of being stored in External memory equipment at least comprises: for boot Boot Loader, kernel, root file system and the application program of Boot Dernel, root file system operation.
In the present embodiment, default burning script does not rely on kernel and root file system operation.Default burning script is stored in External memory equipment equally.
In the present embodiment, primary processor in embedded system is reading from External memory equipment burning boot, burning boot is write in the internal memory of embedded system, burning boot in writing the internal memory of embedded system after, move described burning boot, guiding does not rely on the default burning script operation of kernel and root file system operation, and the recordable paper for the treatment of in described External memory equipment is burned onto in the Flash of described embedded system.
Concrete, primary processor is at the default burning script of operation, by the detailed process that recordable paper is burned onto in the Flash of embedded system for the treatment of in External memory equipment, be: the default burning script of operation, each son file (as Boot Loader, kernel, root file system and application program) that recordable paper comprises for the treatment of in External memory equipment is burned onto in the assigned address of Flash one by one, adopts and avoided in this way causing the situation of programming failure to occur because programming region exists bad block.
In this application, because the primary processor in embedded system is when receiving burning instruction, from External memory equipment, read burning boot, the burning boot reading by operation, guiding does not rely on the default burning script operation of kernel and root file system operation, the recordable paper for the treatment of in described External memory equipment is burned onto in the Flash of described embedded system, therefore, without after kernel and root file system move, carry out again burning, shorten recordable time, improved burning efficiency.
Further, because the primary processor in embedded system is when receiving burning instruction, what from External memory equipment, read is burning boot, and do not read the boot of Boot Dernel and root file system operation in External memory equipment, do not allow kernel and root file system move, reduce the resources occupation rate of primary processor, improved the burning performance of embedded system.

Step S21: the primary processor in embedded system, when receiving burning instruction, reads burning boot from the External memory equipment being connected with described embedded system.
Step S22: described primary processor moves described burning boot, guiding does not rely on the default burning script operation of kernel and root file system operation, the recordable paper for the treatment of in described External memory equipment is burned onto in the Flash of described embedded system, and described default burning script is stored in described External memory equipment.
Step S21 is identical with step S12 with the step S11 in the embedded system program method for burn-recording shown in Fig. 1 with step S22, does not repeat them here.
Step S23: by described External memory equipment treat recordable paper be burned onto the Flash of described embedded system in after, remove described External memory equipment, restart described embedded system.
By in External memory equipment after recordable paper is burned onto in the Flash of embedded system, External memory equipment is removed from embedded system, and restarts embedded system, the embedded system after restarting can come into operation.
In said method embodiment, the primary processor in described embedded system reads burning boot and is specifically as follows from the External memory equipment being connected with described embedded system: the primary processor in embedded system reads burning boot from the SD card being connected with described embedded system.
Because the read or write speed of SD card is faster than other modes (as cd-rom recorder passes through serial ports) speed, therefore when recordable paper is very large, adopt the storage of SD card to treat recordable paper, the high advantage of efficiency that reads the mode for the treatment of recordable paper from SD card particularly highlights.
Certainly, the primary processor in described embedded system reads burning boot and can be also specifically from the External memory equipment being connected with described embedded system: the primary processor in embedded system reads burning boot from the USB flash memory driver being connected with described embedded system.
