In embedded OS, BootLoader is run before operating system nucleus operation.It can initialize
Hardware device establishes memory headroom mapping graph, so that the hardware environment of system is taken to a proper states, to be final
Call operation system kernel gets out correct environment.In embedded systems, usually there is no the firmware journeys as BIOS
Sequence (note, as soon as some embedded type CPUs can also embed a section short and small startup program), therefore the load starting task of whole system is complete
It is completed entirely by BootLoader.In an embedded system based on ARM7TDMI core, system is when powering on or resetting
Usually all from the 0x00000000 of address execute, and at this address arrange usually be exactly system BootLoader
Program.
Operating system nucleus, operating system nucleus refer to the core of most of operating systems.It is by operating system
It is formed for managing those of memory, file, peripheral hardware and system resource part.Operating system nucleus usually runs process, and
Communication between offer process.
U-Boot, full name Universal Boot Loader are the open source code projects for following GPL clause.U-Boot's
Effect is System guides.U-Boot is from FADSROM, 8xxROM, PPCBOOT gradually development and evolution.Its source code catalogue, compiling
Form is much like with linux kernel, in fact, many U-Boot source codes are exactly to be carried out according to corresponding linux kernel source program
Simplified and formation, the driver of especially some equipment, this can embody this point from the annotation of U-Boot source code.
Referring to Fig.1, it is method flow schematic diagram according to the preferred embodiment of the invention:
The following steps are included: S100, starting bootload, setting aim at the guarantor in specified memory region system bootload day

The S300 further include: S301, system kernel are according to specified memory area information, simultaneously by corresponding internal memory initialization
The device node of system bootload log in the memory can be read in creation；After S302, activation system, corresponding application program is called
System bootload log is read according to device node and is handled.
Further include: S1, starting bootload, setting aim at the preservation address in specified flash region system bootload day；
S2, the preservation address according to setting, bootload log is stored in specified flash address, and by specified flash area information
Pass to core system；S3, activation system kernel navigate to specified memory and guiding system starting dress according to flash region information
Carry log.
Further include: buffer area is revised as kernel buffers, makes bootload and core system by S1, starting bootload
Share the same buffer area；S2, bootload log is stored in kernel buffers, is accessed by the interface of kernel buffers
Buffer area obtains corresponding bootload log.
It is apparatus structure schematic diagram according to the preferred embodiment of the invention referring to Fig. 2:
Include: starting module, for starting bootload, system is entered by bootload；Setup module, for being arranged
System bootload day aims at the preservation address in specified memory region；Memory modules, for saving bootload log；Kernel system
System starting module, is used for activation system kernel；Log extraction module, for according to region of memory Information locating to specified memory simultaneously
Guiding system bootload log.
The log extraction module further include: command executing unit, for executing correspondence according to the kernel order line of input
Task, including but not limited to region of memory information the passing to core system of the task.
Further include: internal memory initialization module, for by corresponding internal memory initialization and creating according to specified memory area information
Build the device node that system bootload log in the memory can be read；Application invocation module, for calling corresponding application program
System bootload log is read according to device node and is handled.
Further include: flash memory module aims at the preservation address in specified flash region system bootload day and protects for being arranged
Deposit bootload log；Buffer module is right for application program fire for saving bootload log and open corresponding interface
The bootload log answered.
It is preferred embodiment in accordance with the present invention one referring to Fig. 3:
On startup, log is stored in a piece of specified region of memory by 1.Bootloader, and by the region of memory
Information, kernel is passed to by cmdline；

3. user program can be as needed, and the log for exporting bootloader is handled, and such as saves as after system starting
File uploads to remote server.
The log of bootloader is preserved, can be checked by application program and be done further after system start-up
Reason.
There are following alternative solutions by colleague for implementing:
(1) before bootloader starts kernel, log, which is saved in the file system on flash, (influences starting speed
Degree)；
(2) it before bootloader starts kernel, or is sent by network and is saved on server (influence starting
Speed relies on network)；
(3) modification kernel buffers are realized, the log and kernel log of uboot is allowed to share a buffer area.In this way
In user's space then the log of bootloader can be obtained by the interface of traditional operation kernel buffers.(kernel need to be modified
The mechanism of original buffer area).
