是对于实时性的处理，我看过ti官方的sy***ios系统，但是关于这方面的demo比较少，我也试着去使用了一下，不知道为何仿真就出错，这是我的代码：
Int main()
[
Task_Handle task;
Error_Block eb;
Task_Params taskParams;
/* Enabling functional clocks for GPIO1 instance. */
GPIO1ModuleClkConfig();
/* Selecting GPIO1[23] pin for use. */
GPIO1Pin23PinMuxSetup();
UARTSetup();
/* Enabling the GPIO module. */
GPIOModuleEnable(GPIO_INSTANCE_ADDRESS);
/* Resetting the GPIO module. */
GPIOModuleReset(GPIO_INSTANCE_ADDRESS);
/* Setting the GPIO pin as an output pin. */
GPIODirModeSet(GPIO_INSTANCE_ADDRESS,
GPIO_INSTANCE_PIN_NUMBER,
GPIO_DIR_OUTPUT);
UARTPuts("Enter StarterWare Application...rnn", -1);
System_printf("enter main()n");
Task_Params_init(&taskParams);
taskParams.stackSize = 20480;
taskParams.priority = 1;
Error_init(&eb);
task = Task_create(taskFxn, &taskParams, &eb);
taskParams.priority = 2;
task = Task_create(taskFx1, &taskParams, &eb);
taskParams.priority = 3;
task = Task_create(taskFx2, &taskParams, &eb);
if (task == NULL) [
System_printf("Task_create() failed!n");
BIOS_exit(0);
]
BIOS_start(); /* does not return */
return(0);
]
仿真后的结果：
[CortxA8] 0x44e000ac R8 = 0x4030d028
R1 = 0x00000000 R9 = 0x4030d008
R2 = 0x00000064 R10 = 0x4030d484

R7 = 0x00000020 PC(R15) = 0x800095e0

DFSR = 0x00000005 IFSR = 0x00000000

然后就跳入

请教一下这是什么原因呢？
