Abstract

The invention relates to an equipment tree configuration optimization method and device, computer equipment and a storage medium. The method comprises the following steps: reading an original equipment tree file from a system startup partition, and loading an original equipment tree into a running memory; reading a target equipment tree file from a target configuration partition, loading the target equipment tree file into a running memory, wherein the target configuration partition is obtained by dividing a file system partition; according to the target equipment tree file, modifying child node information of the original equipment tree file to obtain an updated equipment tree file; loading a kernel driver, and obtaining the updated equipment tree file from the running memory; and realizing connection with the target hardware equipment according to the updated equipment tree file. By adopting the method, the maintenance cost of the equipment tree file adaptive hardware can be reduced.

Description

technical field [0001] The present application relates to the technical field of ARM-LINUX system, in particular to a device tree configuration optimization method, device, computer equipment and storage medium. Background technique [0002] With the development of ARM-LINUX system technology, in order to make the ARM-LINUX system adapt to hardware devices, a device tree configuration technology appears. [0003] In the traditional technology, the current ARM-LINUX system uses the device tree method. One software version can only adapt to one hardware configuration. If another hardware configuration is replaced, for example: the hardware configuration of A device is to open the serial port, and the hardware configuration of B device It is to close the serial port. If you want to make the software adapt to the hardware of device A and also adapt to the hardware of device B, you need to modify the device tree file first, compile and generate a software version to upgrade and a...
