Question

通过BSP1.0 / 4将VxWorks 653 2.5.0.2用于P2020RDB-PC目标

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);
}

程序进入START行时，它将重新启动。如果我注释掉START行，它将执行到main的结尾，并且显然什么也没做。我试图增加分区内存，并将APEX组件添加到makefile中。可能是什么原因造成的？

因此，如果其他任何人也遇到类似的问题，就我而言，有两个主要因素会影响该功能。

首先，在usrAppInit（）函数中，无法在函数末尾定义while（1）循环。与其他ARINC-653系统相反，后者的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，将无法定义其他任何内容。

第二，该进程的堆栈大小太小。这非常适合于不同的目标和ARINC RTOS（内部操作系统，在ARMv7目标上执行），但对于P2020目标上的VxWorks，则需要更大的堆栈。在这种情况下，我用了4096。

这里是完整的示例代码，现在可以使用，以防万一有人需要。

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 = 4096;
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);
}

}

void task()
{
  printf("\nI am a process.");
  while(1);
}

VxWorks 653 START命令后重新启动
