 <td> &nbsp;&nbsp;&nbsp;加载vxWorks的boot loader有很多种，最常见的就是使用BSP编译的bootrom <img alt="" src="https://img-blog.csdnimg.cn/img_convert/e0ce65b3b9c7e571666cd71db282db31.png"> 它在Target里的执行顺序如下 
 <ul> 
 <li> romInit() -&nbsp;$(BSP)/romInit.s，这是bootrom的启动地址，它在ROM(例如Flash、硬盘)中执行最小的初始化，包括：初始化CPU、关中断、清Cache、初始化romStart()的栈STACK_SAVE、调用romStart() </li> 
 <li> romStart() - config/all/bootInit.c，这是bootrom的第一条C指令，它将bootrom镜像中未压缩的文本段与数据段从ROM复制到RAM的RAM_LOW_ADRS，然后将RAM中未占用的空间清零，将bootrom的剩余压缩部分解压到RAM的RAM_HIGH_ADRS，最后跳转到这个RAM_HIGH_ADRS处的usrEntry()执行 </li> 
 </ul><img alt="" src="https://img-blog.csdnimg.cn/img_convert/057191404cb9761cf1a776f5289dee14.png"> 
 <ul> 
 <li> usrEntry() - config/all/usrEntry.c，RAM中的第一条指令，它的唯一功能就是调用usrInit() </li> 
 <li> usrInit() - config/all/usrConfig.c，主要工作包括：将BSS清零、初始化Cache库、设置中断向量表基址、安装异常向量、调用sysHwInit()、使能Cache、调用usrKernelCorePreInit()初始化Class、对象、信号量等、初始化wdb、调用usrKernelInit() 
 <ul> 
 <li> usrKernelInit() - comps/src/usrKernel.c，配置内核使用的数据结构，包括初始化内核的Task库、配置调度策略、初始化Tick队列、初始化wind work队列、记录系统内存池尺寸、调用kernelInit()初始化内 </li> 
 <li> kernelInit() - src/wind/kernelLib.c，初始化并启动内核，包括设置中断栈尺寸、设置内存池位置、初始化中断lock-out等级、关闭时间片轮转策略、将系统Tick清零、初始化中断栈、初始化并启动第一个任务tRootTask </li> 
 </ul></li> 
 <li> usrRoot() - config/all/usrConfig.c，这就是系统第一个任务的入口地址，主要负责post-kernel的初始化，逐步加载系统服务，它内部同样由大量初始化函数组成 
 <ul> 
 <li> usrKernelCoreInit() - src/config/usrKernelCore.c，初始化内核的一些机制，包括Event、信号量的open机制、消息队列及open机制、看门狗、任务的open机制等 </li> 
 <li> memInit() - src/os/mm/memLib.c，初始化系统内存池 </li> 
 <li> usrMmuInit() - comps/src/usrMmuInit.c，初始化MMU </li> 
 <li> usrKernelCreateInit() - src/config/usrKernelCore.c，初始化内核对象的creation机制，例如任务、消息队列、看门狗 </li> 
 <li> sysClkConnect() - src/drv/timer/xxxTimer.c，挂接系统时钟ISR，调用sysHwInit2() </li> 
 <li> sysHwInit2() -&nbsp;$(BSP)/sysLib.c，挂接中断，配置其它附加信息 </li> 
 <li> iosInit() - src/os/io/iosLib.c，初始化IO系统 </li> 
 <li> tyLibInit() - src/os/io/tyLib.c，初始化TTY库 </li> 
 <li> ttyDrv() - src/os/io/ttyDrv.c，初始化TTY驱动 </li> 
 <li> ttyDevCreate - src/os/io/ttyDrv.c，创建TTY设备 </li> 
 <li> 初始化其它机制，例如任务级job机制、message logging库、管道驱动、标准IO库、ERF(Event Reporting Framework)库、设备管理、文件系统相关机制、pty(pseudo-terminal)驱动、存储设备加载、Boot Line解析等 </li> 
 <li> bootAppShellInit() - src/boot/bootAppShell.c，初始化<a href="https://www.oschina.net/action/GoToLink?url=http%3A%2F%2Fmp.weixin.qq.com%2Fs%3F__biz%3DMzU1NTIxMTI0MQ%3D%3D%26mid%3D2247484177%26idx%3D1%26sn%3Db3d662a083d8fb35c8ac40c57caab738%26chksm%3Dfbd68397cca10a81118af1212ca9ce3784df5b0d57d95907d265cd085c3ac85ae056d6828ec9%26scene%3D21%23wechat_redirect" rel="nofollow">Boot Shell</a> </li> 
 <li> Boot方式的初始化，例如文件系统、网络 </li> 
 <li> bootApp() - src/boot/bootApp.c，启动Boot Loader主任务bootApp </li> 
 </ul></li> 
 <li> bootAppTask() - src/boot/bootApp.c，bootApp的入口地址。它默认先等待7秒，如果Boot Shell接收到命令，则解析执行；如果7秒倒计时结束，则按照Boot Line将vxWorks镜像加载到RAM_LOW_ADRS，然后跳转到这个地址<a href="https://www.oschina.net/action/GoToLink?url=http%3A%2F%2Fmp.weixin.qq.com%2Fs%3F__biz%3DMzU1NTIxMTI0MQ%3D%3D%26mid%3D2247485010%26idx%3D1%26sn%3D42fb6186d4e621c37923ec65197d4839%26chksm%3Dfbd686d4cca10fc2d5611f202ef2ea940c401761095936ad8ab8f0ac7c9444f20e8d598e6859%26scene%3D21%23wechat_redirect" rel="nofollow">开始执行vxWorks</a> </li>
