Problems solved by technology

The boot loader of the WindowsCE system is developed by Microsoft for the combination of nboot and eboot. Compared with the open uboot, the combination of nboot and eboot is too complicated, which is not conducive to the cross-platform promotion and application of the WindowsCE system.

Embodiment Construction

[0016] The present invention will be further described below in conjunction with drawings and embodiments.

[0017] The invention provides a method for bootloading a WindowsCE system based on uboot. The hardware platform adopts the Mini6410 development board produced by Friendly ARM Company. The platform can be used as a development platform for mobile devices such as tablet computers and mobile phones. The main hardware configuration is as follows: ARM architecture CPU (Samsung S3C6410A, ARM1176JZF-S core, main frequency 533MHz, maximum 667Mhz), DDR memory (256M DDR RAM, 32bit data bus), Nand Flash memory (1GB Nand Flash, non-volatile when power off ), various peripherals and interface modules (resolution 800x6407-inch LCD display, buttons, SDIO interface, etc.).

[0018] Method of the present invention specifically comprises the following steps:

[0019] (1) Partition the memory to divide the address space of the memory into the first storage space for storing the uboot.bin...

Abstract

The invention discloses a method for loading a Windows CE system based on uboot guidance and belongs to the technical field of operation system guidance loading of a mobile device. The mobile device is electrified, a uboot program is started to complete initialization of internal and external devices, a Windows CE core is read from a memorizer to an internal storage, and operation is skipped to a core starting address in the internal storage to start the Windows CE system. By means of the method, uboot abiding by a GPL clause is used for replacing the guidance loading programs nboot and eboot of the Windows CE system, the redundancy of the guidance loading programs of the system is reduced, the uboot university is improved, and the application range of the Windows CE system is also widened.

Description

technical field [0001] The invention relates to a method for bootloading a WindowsCE system based on uboot, and belongs to the technical field of bootloading of operating systems of mobile devices. Background technique [0002] U-Boot, the full name of Universal Boot Loader, is an open source project that follows the terms of the GPL. U-Boot is famous for its versatility and supports the bootloading of embedded kernels such as Linux, NetBSD, VxWorks, QNX, RTEMS, ARTOS, and LynxOS. PowerPC, ARM, x86, MIPS, XScale and other processor series can also guarantee their high reliability and stability, but they do not support the bootloading of the WindowsCE system. [0003] WindowsCE system is an operating system for embedded devices launched by Microsoft Corporation. WindowsCE system has outstanding advantages such as enterprise-level stability, simple thread management, and flexible database capacity. It is widely used in industrial fields and consumer electronics. product. The...
