Description
Technical field
The present invention relates to the booting operating system loading technique field of mobile device, more particularly to one kind Uboot
CDROM starts WinCE implementation method, and CD-ROM drive and Uboot bootstrap are based on applied to mobile device.
Background technology
Uboot full name are Universal Boot Loader, i.e., general Bootloader, and one kind is commonly used to embedded
Bootloader in system, be a source code disclose, powerful board suppot package.Support some serial arm bodies
System, subsequent development is loaded for the guiding of WinCE systems.Uboot includes common peripheral hardware driving and different file systems
System, but driven without CODROM drivings under direct uboot, it is necessary to develop CODROM under uboot.
WinCE is a opening, scalable 32 embedded OSs for embedded device are, it is necessary to root
The specific embedded OS customized according to embedded hardware apparatus modifications, it is impossible to general.The guiding of usual WinCE systems adds
It is not succinct enough for the Boot loader modes that load program combines for nboot and eboot, more open uboot, and
Uboot is based on most complete one general Boot loader of GPL clauses.But uboot is to WinCe system kernels source
The acquisition modes of file are relatively simple.
The content of the invention
In order to solve problem of the prior art, the invention provides the realization side that a kind of use Uboot CDROM start WinCE
Method, it can increase the mode that Uboot guiding loading WinCE systems start, extend uboot and WinCE systematic difference models
Enclose.Dependence of the WinCE systems to embedded platform hardware is reduced simultaneously, mitigates the load at embedded platform end.
The technical solution adopted in the present invention is as follows：
A kind of use Uboot CDROM start WinCE implementation method, comprise the following steps：
A, to memory address space carry out subregion, be divided into for storing uboot mirror images, WinCE Eboot and kernel mirror image
Region；
B, exploitation CDROM drivers and WinCE mirror image recognizers in Uboot；
C, add bootstrap in Uboot, including and Eboot mirror images and WinCE mirror images bootstrap；
D, according in step A, the partition size that internal memory is divided changes memory partition defined in the BSP source codes of WinCE kernels
File loader.h, and modification makefile and config files recompilate BSP source codes, generate new Eboot
With WinCE kernel mirror image files, now Eboot and NK jump address has corresponding with step A memory partitioning in mirror image
Corresponding relation；
E, newly-generated Eboot and kernel mirror image file be burnt in CD.
Step B specific methods are：By increasing fs.h, fs.c file correlation iso-9660 file system letters in Uboot
Number, increases specific iso-9660 drivings file, configuration uboot under fs files and respectively configures compiling file, while in isoload
After order, WinCE mirror image recognizers are developed.
Implementation method also includes step F：CDROM drivings can recognize CDROM connections in Uboot after electrifying startup, and CDROM drives
Isoload orders in dynamic start CDROM CD-ROM drives, to read specified file name from CD, are then recognized by WinCE mirror images
Program, and identification Eboot image files and WinCE system kernel mirror images are verified, by according to configuration file config.bib's
Configuration parameter, the appropriate address position of internal memory is divided by using nandwrite order write steps A, calls Eboot to start life
Order, starts Eboot, and the Uboot CDROM for completing WinCE start.
The beneficial effect that the technical scheme that the present invention is provided is brought is：
The peripheral hardware driving of uboot supports is added, the start-up loading mode for also increasing WinCE systems is that uboot CDROM is opened
It is dynamic, the dependence that WinCE systems are combined guiding load mode for primary nboot with eboot is reduced, WinCE is enhanced
The portability of system.The versatility of Uboot guiding, overcomes WinCE operating systems to the dependence of particular hardware platform.
Brief description of the drawings
Technical scheme in order to illustrate more clearly the embodiments of the present invention, below will be to that will make needed for embodiment description
Accompanying drawing is briefly described, it should be apparent that, drawings in the following description are only some embodiments of the present invention, for

Embodiment
To make the object, technical solutions and advantages of the present invention clearer, below in conjunction with accompanying drawing to embodiment party of the present invention
Formula is described in further detail.
Embodiment one
A kind of use Uboot CDROM of the present embodiment start WinCE implementation method：
1）Using Flash partitioning techniques, divided by memory address space according to the size of the WinCE systems of different platform
Area such as Fig. 2, is divided into for storing uboot mirror images, Eboot mirror images and each region of WinCE kernel mirror images, and with preserving each subregion
Location.
2）By increasing the files such as fs.h, fs.c correlation iso-9660 file system functions in Uboot, in fs files
The specific iso-9660 drivings file of the lower increase of folder, configuration uboot respectively configure compiling file.Simultaneously after isoload orders,
Increase Eboot and WinCE mirror images verification recognizer.
3）Bootstrap is added in Uboot, includes the bootstrap of Eboot mirror images and WinCE mirror images.
4）According to step 1）In, internal memory divide block partition sizes, change WinCE kernels BSP source codes defined in
The file loader.h of memory partition, and modification makefile and config files, recompilate BSP source codes, so that
Mirror image operation address is correctly corresponding with memory partitioning.Generation new Eboot and kernel mirror image file NK.nb0.
5）By newly-generated Eboot and the storage of kernel mirror image file into foreign medium CDROM.
6）After the uboot changed above is recompilated, store into corresponding memory partitioning, uboot after electrifying startup
Interior CDROM driving can recognize CDROM connections, and verify and recognize Eboot image files and WinCE system kernel mirror images, will be by
According to configuration file config.bib configuration parameter, the appropriate address position of internal memory is write by using nandwrite orders, is adjusted
With order is started, start Eboot, the CDROM for completing WinCE starts.
The foregoing is only presently preferred embodiments of the present invention, be not intended to limit the invention, it is all the present invention spirit and
Within principle, any modifications, equivalent substitutions and improvements made etc. should be included within the scope of the present invention.
