VxWorks 653 在 START 命令后重新启动
VxWorks 653 Restart after START command
使用 VxWorks 653 2.5.0.2 作为 P2020RDB-PC 目标,使用 BSP1.0/4
我有一个非常简单的测试应用程序
void usrAppInit (void)
{
RETURN_CODE_TYPE errCode;
printf("\n I am alive!");
PROCESS_ATTRIBUTE_TYPE processAttributes;
PROCESS_ID_TYPE thandle;
processAttributes.BASE_PRIORITY = 10;
processAttributes.DEADLINE = SOFT;
processAttributes.ENTRY_POINT = (SYSTEM_ADDRESS_TYPE)task;
strncpy(processAttributes.NAME, "TASK", MAX_NAME_LENGTH);
processAttributes.PERIOD = INFINITE_TIME_VALUE;
processAttributes.STACK_SIZE = 1024;
processAttributes.TIME_CAPACITY = INFINITE_TIME_VALUE;
CREATE_PROCESS(&processAttributes, &thandle, &errCode);
if(errCode != NO_ERROR)
{
printf("Just had an error creating the task: %d", errCode);
}
else
{
START(thandle, &errCode);
if(errCode != NO_ERROR)
{
printf("Just had an error starting the task: %d", errCode);
}
}
SET_PARTITION_MODE (NORMAL, &errCode);
if (errCode != NO_ERROR){
printf("\nError changing partition mode: %d", errCode);
}
while(1);
}
void task()
{
printf("\nI am a process.");
while(1);
}
当程序到达 START 行时,它会重新启动。如果我注释掉 START 行,它会一直执行到 main 结束并且显然什么都不做。我尝试增加分区内存,并将 APEX 组件添加到 makefile。
可能是什么原因造成的?

在此之后,它returns从头开始并一直重复这个过程
因此,如果其他人遇到类似问题来到这里,就我而言,有两个主要因素会影响功能。
首先,在usrAppInit()函数中,不能在函数末尾定义while(1)循环。与其他 ARINC-653 系统相反,分区主分区与用户主分区相同,对于 VxWorks 似乎并非如此。这样,在SET_PARTITION_MODE之后,就不能再定义其他了。
其次,进程的堆栈大小太小。这非常适合不同的目标和 ARINC RTOS(内部 OS,在 ARMv7 目标上执行),但对于 P2020 目标上的 VxWorks,它需要更大的堆栈。在本例中,我使用了 4096。
这是完整的示例代码,现在可以使用,以备不时之需。
