Description of the Invention (I) [Field of the Invention] The present invention relates to the technical field of year-entry systems, especially an embedded system that can quickly and quickly update software And a method for quickly updating embedded system software. [Background of the Invention] It is known that during the development process of an embedded system, it is often necessary to continuously update the contents of the flash memory through a communication device to test whether the new code is correct. However, in the design of the embedded system using the communication device as the medium to write the software to the flash memory, if a high-speed communication device is used, the design of the circuit and the programming software becomes complicated, and the processor and memory requirements are very high. High, it is disadvantageous to development cost and time. Therefore, based on considerations of cost and circuit complexity, general embedded systems are not necessarily equipped with high-speed communication devices, and the communication protocols used by South-speed communication devices are often used. More complicated 'cause the programming software itself is not suitable for embedded systems with small memory capacity and low execution capacity. If a simple low-speed communication device is used as the medium, the nest burning efficiency will be limited by the communication bandwidth and will be reduced. As a result, the waiting time for downloading will often be quite lengthy and will take up valuable time of the program developer. Therefore, how to avoid the above-mentioned shortcomings and effectively update the software of embedded systems quickly has become a problem to be solved. Because of this, the inventor, based on the spirit of active invention, thinks of an "embedded system that can quickly update software and a method to quickly update embedded system software" that can solve the above problems. A novel and progressive invention.

Description of the invention (2) [Summary of the invention] One of the purposes of the invention is to provide an embedded software that can quickly update System, which uses pluggable storage media as the medium to update the embedded system < software, and simplify the embedded system's circuit design for system development. Another object of the present invention is to provide a method for quickly updating the human body of an embedded system library. By using a pluggable storage medium as a medium to update the software of the embedded system, the development time of the embedded system software is effectively shortened. 〇 According to a feature of the present invention, a plug-in system capable of quickly updating software is proposed, which mainly includes: a central processing unit; and a memory device, which stores a boot load in advance on a reset memory address. Into the program; and, a pluggable storage medium for storing software to be updated to the memory to device. Wherein, after the embedded system is reset, the central processing system first executes the boot loader to initialize the system. After the embedded system is initialized, it is determined whether a predetermined setting description file exists in the pluggable storage medium. If so, the specific software preset in the pluggable storage medium is copied to the system memory device according to the content of the setting description file. According to another feature of the present invention, a method for rapidly updating embedded system software is proposed. The embedded system has a memory device and a pluggable storage medium. The memory device resets the memory address. A pre-loading program is stored in advance. The method mainly includes the following steps: (A) storing software to be updated to the memory device in the pluggable storage medium; (B) resetting the embedded System to execute the paper rule mm Guan Jia Xian --- — — — — — — — — — — — — — ki!
