Description of the Invention: [Technical Field of the Invention] The present invention relates to a motherboard support package (BSP) tool, and more particularly to a universal BSP tool for embedded system assisted transplantation and its application method. [Prior Art] As the system performance and computing power of computers continue to increase, embedded operating systems play an important role in embedded systems. Good operating systems can effectively utilize system sources and control execution factors. In general, porting is a necessary program for programs to be executed in different hardware environments. In order to execute embedded systems, system developers usually migrate operating systems or applications to embedded systems. In this case, they need to be changed. System code. / One Board Support Package (BSP) is a layer between the main board and the operating system and is part of the operating system. The main purpose is to support the operating system so that it can run on the motherboard. Bsp is relative to the hardware platform and the operating system. Different operating systems correspond to different definitions. For example, ^xWorks and Linux systems, BSPs relative to a certain processor (functions written by the pr tube) And the interface definition may be completely different. The same == the same = the station also defines different forms of BSP, for example, Linux is different in different processors. Because the BSP stylization process is mostly in a certain shape Na, 仃L change', so the BSP must be written in accordance with the definition of the system BSP, in order to maintain the correct interface with the upper layer, good support on the ^ ARM> MIPS. XScale "operation" two to write a hard view Grid is set up in the first technology * towel, the development of the establishment of a health-friendly system, usually using the 1294589 Weishang provided by the hardware platform, operating systems and tools, etc. Various environmental requirements in the system to modify the operating system two-time control (real-tme c〇ntrol) or a small footprint (f〇〇 two operating systems can not meet all environmental needs, the developer must be aged: This hardware On the platform to implement, (4), to operate on the _ hardware platform, it is necessary to move the system to the human system. Before transplanting the job system and the hardware platform of Chen Shiqi, the developer must first understand the characteristics of the hardware platform. But hard j
