i.MX28 EVK开发板从开箱到启动：ARM9嵌入式系统实战指南嵌入式系统开发始于对硬件平台的深入理解与正确配置。其核心在于处理器启动流程与板级支持包（BSP）的协同工作。启动流程定义了处理器上电后如何加载并执行第一段代码，而BSP则包含了操作系统与具体硬件主板之间的所有驱动和适配层，是系统稳定运行的基石。这种软硬件协同设计，对于工业控制、物联网网关等需要高可靠性和特定外设支持的应用场景至关重要。本文以经典的ARM9架构i.MX28处理器及其评估套件（EVK）为例，详细解析了从启动模式配置、电源管理到串口调试、系统启动的全过程，并提供了针对SD卡启动、Linux/Win 阅读详情

请问大家，我通过Ethernet下载Debug Image到开发板上，当Attach Device之后的进度条完成后，开发板就自动重启了，这是什么原因呢？
开发板板载2个网卡，我用的8139C来下载的镜像。
Build Options选项是：
Enable eboot space in memory;
Enable kernel debugger;
Enable KITL;
Run-time image can be large than 32MB;(选择这个是因为我build的镜像50多MB)
Connctivity Options选择是：
Download&&Transport: Ethernet;
Debugger:KdStub.
Output窗口的信息显示
