vxWorks应用程序如何能让系统重启？
------解决方案--------------------------------------------------------
reboot函数。参见帮助。
------解决方案--------------------------------------------------------
直接写控制重启的那个寄存器。
------解决方案--------------------------------------------------------
没有重启是你的BSP没有支持。
------解决方案--------------------------------------------------------
嵌入式系统中一般都有硬件狗，有CPU狗也有外狗，确认一下它是如何设置的，如果已经使能了锁中断之后死循环
就可以复位，比调reboot要彻底一些。
------解决方案--------------------------------------------------------
STATUS sysToMonitor
(
int startType /* parameter passed to ROM to tell it how to boot */
)
就是它了~~reboot最后会调用到这个函数
其实应用程序可以使用的RESET要查找CPU的软硬中断资源的~~实在不行WDT超时不也重启了
------解决方案--------------------------------------------------------
roboot函数并不会充气系统，但会调用syslib.c中的sysToMonitor函数
/*******************************************************************************
*
* sysToMonitor - transfer control to the ROM monitor
*
* This routine transfers control to the ROM monitor. Normally, it is called
* only by reboot()--which services ^X--and by bus errors at interrupt level.
* However, in some circumstances, the user may wish to introduce a
* <startType> to enable special boot ROM facilities.
*
* The entry point for a warm boot is defined by the macro ROM_WARM_ADRS
* in config.h. We do an absolute jump to this address to enter the
* ROM code.
*
* RETURNS: Does not return.

taskSpawn("rebooting", 10, 0, 1024, (FUNCPTR)reboot,
BOOT_QUICK_AUTOBOOT, 0, 0, 0, 0, 0, 0, 0, 0, 0);
------解决方案--------------------------------------------------------
(void(*)(void))reset_addr
其中reset_addr就是你的复位地址，根据你的CPU类型和你的BSP设置定
------解决方案--------------------------------------------------------
reboot让系统重新创建任务。
