我用的是stm32F427平台跑rt-thread，有时候系统跑着跑着就遇到线程卡死的情况，串口不能用，只看到那个运行指示灯在一闪一闪的，所以我决定还是把我写的软件其中创建了哪些线程，给大家看一下，可以的话指导我一下找到问题所在。
```#define HYGJDEV_TCPS_LINTEN_THREAD_NAME         "tcplistn"
#define HYGJDEV_TCPS_LINTEN_THREAD_PRIO         17
#define HYGJDEV_TCPS_LINTEN_THREAD_TICK         50
#define HYGJDEV_TCPS_LISTEN_THREAD_STACK_SIZE        1024

#define HYGJDEV_TCPS_RECV_THREAD_NAME           "tcprecv"
#define HYGJDEV_TCPS_RECV_THREAD_PRIO           17
#define HYGJDEV_TCPS_RECV_THREAD_TICK           50
#define HYGJDEV_TCPS_RECV_THREAD_STACK_SIZE     1024``````   tcp_listen_thread = rt_thread_create(HYGJDEV_TCPS_LINTEN_THREAD_NAME, 
                                         hygjdev_listen_thread_entry, 
                                         RT_NULL, 
                                         HYGJDEV_TCPS_LISTEN_THREAD_STACK_SIZE, 
                                         HYGJDEV_TCPS_LINTEN_THREAD_PRIO, 
                                         HYGJDEV_TCPS_LINTEN_THREAD_TICK);
    if (RT_NULL != tcp_listen_thread) {
            rt_thread_startup(tcp_listen_thread);
    } else {
            rt_kprintf("Fail to create tcp listen thread<br>");
    }

// tcp recv thread.
    tcp_recv_thread = rt_thread_create(HYGJDEV_TCPS_RECV_THREAD_NAME, 
                                       hygjdev_recv_thread_entry, 
                                       RT_NULL, 
                                       HYGJDEV_TCPS_RECV_THREAD_STACK_SIZE, 
                                       HYGJDEV_TCPS_RECV_THREAD_PRIO, 
                                       HYGJDEV_TCPS_RECV_THREAD_TICK);
    if (RT_NULL != tcp_recv_thread) {
            rt_thread_startup(tcp_recv_thread);
    } else {
            rt_kprintf("Fail to create tcp recv thread<br>");
    }```以上是创建tcp服务器的线程代码
```led_thread = rt_thread_create("led", led_thread_entry, RT_NULL, 512, 10, 10);
    rt_thread_startup(led_thread);
    
    uart_thread = rt_thread_create("uart3", uart_thread_entry, RT_NULL, 1024, 18, 30);
    rt_thread_startup(uart_thread);

key_thread = rt_thread_create("key", key_thread_entry, RT_NULL, 768, 18, 30);
    rt_thread_startup(key_thread);
   
    lcd_thread = rt_thread_create("lcd", lcd_thread_entry, RT_NULL, 2048, 18, 30);
    rt_thread_startup(lcd_thread);
                
                
   temperature_thread = rt_thread_create("temperature_thread", temperature_thread_entry, RT_NULL, 1024, 18, 30);
   rt_thread_startup(temperature_thread);

//dac_thread
 dac_thread = rt_thread_create("dac_thread", dac_thread_entry, RT_NULL, 1024, 18, 30);
   rt_thread_startup(dac_thread);
        
                 //autojust
                 autojust = rt_thread_create("autojust", autojust_thread_entry, RT_NULL, 2048, 18, 50);
                 rt_thread_startup(autojust);
                
                var1_all  = rt_thread_create("var1all", dac_thread_var1_all, RT_NULL, 512, 10, 5);
                 rt_thread_startup(var1_all);`````` adc_thread = rt_thread_create("adc_read", adc_thread_entry, RT_NULL, 2048, 0, 50);
        rt_thread_startup(adc_thread);```以上一些普通的线程创建怎么合理安排这些线程的权限级别，栈大小，时间片才不会导致死机的情况
