Abstract: As the core component of the Linux operating system, the rootfiles system is the most critical step in system on chip (SOC) embedded development. This article mainly studies how to use Buildroot to build the Linux rootfiles system on the advanced RISC machines (ARM) side, which specifically introduces the configuration, construction and use of resource tools. The article uses the IMX6ULL core board as the test platform, and burned the self-transplanted rootfiles system into the board, which enhances the flexibility of rootfiles system construction and improves the efficiency of system-level embedded development.

摘要： 根文件系统作为 Linux 操作系统的核心组成部分，是片上系统（Syestem On Chip, SOC） 嵌入式开发中最关键的一步。主要研究探讨如何使用 Buildroot 方法，构建 ARM 端的 linux 根文件系统，具体介绍了资源工具的配置、构建及使用方法。以 IMX6ULL 核心板作为测试 平台，将自主移植的根文件系统烧录在开发板中，增强了根文件系统构建的灵活性，提高了 系统级嵌入式开发效率。
