Problems solved by technology

In addition, there is also a version control problem between the boot loader and the operating system image file
Since the existing boot mechanism also lacks effective version verification capabilities, the stability and reliability of the embedded system are greatly jeopardized.

Embodiment Construction

[0035] In order to make the above-mentioned objects, features and advantages of the present invention more comprehensible, the following specific embodiments will be described in detail in conjunction with the attached figures.

[0036] The present invention provides systems and methods to overcome the aforementioned power-on problems.

[0037] figure 1 It is a schematic diagram showing a dynamic boot system according to an embodiment of the present invention. The dynamic boot system 100 according to the embodiment of the present invention can be any processor-based electronic device, such as embedded systems such as computers, personal digital assistants, mobile phones, and smart phones. The dynamic boot system 100 at least includes a block storage device 110 , a boot loader 120 , and a memory 130 .

[0038]The block storage device 110 is a data storage device accessed in a block manner, such as a NAND type memory or a hard disk. The block storage device 110 at least store...

Abstract

The invention relates to a dynamic starting up system and method, and the constructing method for operation system mapping file. It includes a memory, a storage device, and a starting up loading program. The storage device at least contains an executive mapping file like operation system mapping file and starting up information file, which at least records location, length and starting location information. While starting up, the starting up loading program would read starting up information file from storage device, read executive mapping file, and copy the executive mapping file into memory from starting location.

Description

technical field [0001] The present invention relates to boot management, and particularly relates to a system and method capable of providing dynamic boot, and an operating system image file construction method used in the dynamic boot system and method. Background technique [0002] With the convenience of portable devices, embedded systems such as personal digital assistants (PDAs), mobile phones, and smart phones have become one of people's necessities. [0003] In the memory for data storage, it can be roughly divided into two different types of memory: one is parallel (Parallel) memory, such as NOR type flash memory (Flash), and the other is serial (Serial) memory, Such as NAND type memory, or block storage device (Block Storage Device). Since the parallel memory is accessed through a parallel I / O interface, the parallel memory can provide a higher system access rate. In addition, since the parallel memory can provide the smallest unit accessed by the processor system...
