摘要: 本文基于QEMU vexpress-a9平台，搭建无需硬件的RT-Thread调试环境。通过arm-none-eabi-gdb远程连接，跟踪系统上电、MMU/页表建立、堆初始化、多任务调度、中断异常与设备驱动全过程；并对RT-Thread的初始化全流程进行分析说明。
Abstract: This article is based on the QEMU vexpress-a9 platform to build a hardware-free RT-Thread debugging environment. Through the remote connection of arm-none-eabi-gdb, the entire process from system power-on, MMU/page table establishment, heap initialization, multi-task scheduling, interrupt exceptions and device drivers is tracked; and the entire initialization process of RT-Thread is analyzed and explained.
