static void startTask(void *arg)
{
taskENTER_CRITICAL(); /*½øèëáù½çÇø*/

xTaskCreate(radiolinkTask, RADIOLINK_TASK_NAME, RADIOLINK_TASK_STACKSIZE, NULL, 6,NULL);

xTaskCreate(mspTxTask, MSP_TX_TASK_NAME, MSP_TX_TASK_STACKSIZE, NULL, 3,NULL);
xTaskCreate(mspRxAnlTask, MSP_RX_TASK_NAME, MSP_RX_TASK_STACKSIZE, NULL, 8,NULL);

xTaskCreate(driversTxTask,DRIVER_TX_TASK_NAME,DRIVER_TX_TASK_STACKSIZE,NULL,4,NULL);
xTaskCreate(driversRxAnlTask,DRIVER_RX_TASK_NAME,DRIVER_RX_TASK_STACKSIZE,NULL,6,NULL);

// xTaskCreate(commanderAnlTask,COMMANDERANL_TASK_NAME,COMMANDERANL_TASK_STACKSIZE,NULL,5,NULL);

printf("Free heap: %d bytes\r\n", xPortGetFreeHeapSize());
vTaskDelete(startTaskHandle);
taskEXIT_CRITICAL();
}

void commanderAnlTask(void *param)
{
while(1)
{
vTaskDelay(8);
}
}

现在遇到了一个问题，当不创建commanderAnlTask任务时，可以执行printf且其他任务也在执行，但是不注释commanderAnlTask任务，则其他任务也不执行，printf也不执行了，
commanderAnlTask此任务内部就只有一个vTaskDelay(8);大家帮忙分析分析是怎么回事，困扰几天了---
