串口错误：
```
(rt_object_get_type(&mutex->parent.parent) == RT_Object_Class_Mutex) assertion failed at function:rt_mutex_take, line number:6\0
```

驱动代码：
```c
#include <rtthread.h>
#include <rtdevice.h>

#define W25Q64_SPI_NAME "spi1"

static void spi_w25q64_readID(int argc,char *argv[]){
	
	struct rt_spi_device *spi_w25q64;
	//char name[RT_NAME_MAX];
	
	rt_uint8_t w25q64_read_id=0x90;
	
	rt_uint8_t id[5];
	rt_kprintf("1111\r\n");
	spi_w25q64=(struct rt_spi_device *)rt_device_find(W25Q64_SPI_NAME);
	rt_kprintf("2222\r\n");
	if(!spi_w25q64){
		rt_kprintf("can't find spi1\r\n");
	}else{
		rt_kprintf("3333\r\n");
		/*
		rt_spi_send_then_recv(spi_w25q64,&w25q64_read_id,1,id,5);
		rt_kprintf("w25q64:%x%x\r\n",id[3],id[4]);
		*/
		struct rt_spi_message msg1,msg2;
		msg1.send_buf=&w25q64_read_id;
		msg1.recv_buf=RT_NULL;
		msg1.length =1;
		msg1.cs_take=1;
		msg1.cs_release=0;
		msg1.next=&msg2;
		
		msg2.send_buf=RT_NULL;
		msg2.recv_buf=id;
		msg2.length =5;
		msg2.cs_take=0;
		msg2.cs_release=1;
		msg2.next=RT_NULL;
		
		rt_kprintf("4444\r\n");
		rt_spi_transfer_message(spi_w25q64,&msg1);
		rt_kprintf("w25q64:%x%x\r\n",id[3],id[4]);
	}
	
}

MSH_CMD_EXPORT(spi_w25q64_readID,read w25q64 id);
