Method for adapting single board to plurality of peripherals

Abstract

The invention provides a method for adapting a single board to a plurality of peripherals. The method comprises the following steps: 1, a flash memory controller is provided with a flash memory original equipment layer partition in a flash memory; a initialization sequence code is readed from the hardware; the flash memory controller converts the initialization sequence code into a hardware code;wherein the hardware codes are stored in an original equipment layer partition of the flash memory, and the initialization sequence code corresponding to the hardware code is stored in a kernel equipment tree partition of the flash memory; the CPU reads the original equipment layer partition of the flash memoryso that the hardware code is acquired, obtaining an initialization sequence code from akernel device tree partition tree according to the hardware code. The same PCBA is used so that hardware such as LCDs, touch screens, batteries and cameras of different manufacturers and different models can be conveniently used, and the production and after-sales service cost for producing the PCBA is greatly reduced.

Description

technical field [0001] The present invention relates to intelligent terminal equipment, in particular to providing a method for adapting a single board to multiple peripheral devices. Background technique [0002] At present, smart terminal equipment is widely used in China, generally composed of PCBA, touch screen, LCD, battery, casing and other hardware, but different smart terminal equipment vendors may choose different hardware suppliers, the same smart terminal equipment seller It is also possible to choose different hardware suppliers. For example, smart terminal equipment sellers can choose batteries, touch screens, LCDs and other hardware from different suppliers. Usually, the code provided by the hardware supplier can support the LCD of standard design. However, due to the problem of the hardware supplier, most LCDs and touch screens cannot be effectively distinguished. Therefore, it is necessary to add branches to the code here. To distinguish different hardware s...

Problems solved by technology

Usually, the code provided by the hardware supplier can support the LCD of standard design. However, due to the problem of the hardware supplier, most LCDs and touch screens cannot be effectively distinguished. Therefore, it is necessary to add branches to the code here. To differentiate between different hardware suppliers

In the case of large product batches and small single batches, there will be a lot of code branches used here, and at the same time, the maintenance needs are also very large
