Embodiment Construction
[0023] In order to make the purpose, technical solutions and advantages of the present invention clearer, the embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings. Obviously, the described embodiments are only some of the embodiments of the present invention, not all of them. . Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0024] as attached figure 1 As shown, a method for an embedded system to partition different flashes adaptively,
[0025] The BootLoader in the embedded system is often the first piece of code that the main control chip runs, and it undertakes the tasks of initializing the hardware, moving the kernel, and guiding the kernel to start. Because the BootLoader starts before the kernel starts, this article chooses to add the a...

The invention discloses a method for self-adaptive partitioning of different flashes of an embedded system. The method comprises the steps that a code operated by a master control chip in the embedded system in the very beginning is BootLoader based on the embedded system and is used for initializing hardware, wherein the achieving the process of the hardware initialization is that a self-adaptive partitioning function is added for the BootLoader, the flashes are read and written by integrating a flash driving module in the BootLoader. Compared with the prior art, the method for self-adaptive partitioning of different flashes of the embedded system can avoid the situation that different software is developed and maintained due to different flash sizes, self-adaptive partitioning is achieved according to the flash sizes, and software compatibility and zero configuration are achieved. A basic principle is that different partitioning tables are built in the software, appropriate partitioning tables can be automatically selected and applied to the system according to the flash sizes without software replacement, the practicability is high, an application range is wide, and the system has a very high popularization and application value.
Description
technical field [0001] The invention relates to the technical field of computers, in particular to a method for an embedded system to partition different flashes adaptively. Background technique [0002] Embedded systems are different from general-purpose computer systems. The flash partition of an embedded system has no UI presentation and does not require user intervention. The partition table is often placed in the program in advance. In the implementation, it is often required that the embedded software can be compatible with different flash sizes. [0003] The flash partition of the embedded system is often determined by the partition table built in the software module. If you want to change the flash size, you must adjust the flash partition configuration in the source code, then compile it, and enable it again. Different flash sizes must burn programs with different partition tables. This method has many disadvantages, 1) The software cannot be compatible, and the ...
