Problems solved by technology

If the DTS / DTSI file is directly manually configured in text mode, it is not intuitive, error-prone, and inefficient, which is not conducive to software engineers having a comprehensive understanding of the configuration of the entire hardware device information

Abstract

The invention discloses a visual configuration system of a Linux kernel device tree. The visual configuration system comprises a DTS scanning / analyzing module, a DTS generating module, an analyzing / typesetting module and a graphical interface management module. The DTS scanning / analyzing module receives DTS files sent by the outside, replaces and unfolds all contained DTI files, merges the same nodes according to a tree structure, forms a tree relation database structure classified according to the nodes, and generates a first database file; the analysis / typesetting module processes the analysis result to generate a corresponding displayable graphical interface, and reversely analyzes the editing result to generate a second database file; and the DTS generation module converts the second database file into a single DTS file and outputs the single DTS file. According to the system and the method, a software engineer can complete the configuration of the information of the whole hardware equipment in an interactive mode of the visual graphical interface, and the efficiency and accuracy of the software engineer to configure the equipment tree in the transplanting process of the operating system are greatly improved.

Description

technical field [0001] The invention relates to the technical field of device tree configuration, in particular to a system and method for visually configuring a Linux kernel device tree. Background technique [0002] Device Tree (Device Tree) is a data structure that describes hardware resources. It transmits hardware resources to the kernel through the bootloader, making the kernel and hardware resource descriptions relatively independent. The information that Device Tree can describe includes the number and type of CPU, memory base address and size, bus and bridge, peripheral connection, interrupt controller and interrupt usage, GPIO controller and GPIO usage, Clock controller and Clock usage . [0003] At present, the device tree is configured in an ASCII text format called DTS and DTSI, and then converted into a binary DTB format by the conversion tool DTC (DevicTree Compiler), and provided to the operating system kernel. When the operating system kernel is started, t...
