有些线程能运行，有些不能运行，不知道为什么？

```c

    struct rt_thread *tid = NULL;
    rt_err_t result = 0;

    // 静态通信状态邮箱初始化

    }

// 发送信号量初始化
	result = rt_sem_init(&SlaveCanTxSem,  "SlaveCanTxSem",  0,  RT_IPC_FLAG_FIFO);
	if(result != RT_EOK)
	{
        slave_can_dbg_msg("init SlaveCanTxSem failed.\n");

    // 创建及启动发送线程

    if(tid != RT_NULL)
    {
		rt_thread_startup(tid);
    }
    else

    }
     
    // 创建及启动接收线程
    tid = rt_thread_create("slave_can_rx", slave_can_rx_services_entry, RT_NULL, SLAVE_CAN_RX_STACK_SIZE, SLAVE_CAN_RX_PRIORITY, SLAVE_CAN_RX_TICK);
    if(tid != RT_NULL)
    {

    }
    else

    }
}

#define SLAVE_CAN_RX_STACK_SIZE   	(1024u)
#define SLAVE_CAN_RX_PRIORITY     	(2u)
#define SLAVE_CAN_RX_TICK         	(20u)

#define SLAVE_CAN_TX_STACK_SIZE   	(1024u)
#define SLAVE_CAN_TX_PRIORITY     	(3u)
#define SLAVE_CAN_TX_TICK         	(20u)
```

slave_can_tx_services_entry线程就是运行不了，静态初始化也试了，也不行，出鬼了，请大侠协助分析，谁愿意帮我分析，我可以把源工程文件都给他，Jason-PengYunjian，谢谢！
