这是官方例程pinstandby，它只是在线程里调用sleep（）

retc = pthread_attr_setdetachstate(&pAttrs, detachState);
if (retc != 0) {

while (1);
}
pthread_attr_setschedparam(&pAttrs, &priParam);
retc |= pthread_attr_setstacksize(&pAttrs, THREADSTACKSIZE);
if (retc != 0) {

while (1);
}
retc = pthread_create(&thread, &pAttrs, mainThread, NULL);
if (retc != 0) {
/* pthread_create() failed */
while (1);
}
BIOS_start();
return (0);
}
