串口调试问题

参考编程手册上的串口举例，用的2.1.0版本，放进app.c 然后编译的错误：
```"driversusart.c", line 370: Error:  #136: struct "rt_serial_device" has no fiel
d "int_rx"
      serial1.int_rx = &uart1_int_rx;
              ^
"driversusart.c", line 370: Error:  #20: identifier "uart1_int_rx" is undefined
 
      serial1.int_rx = &uart1_int_rx;```

回去usart.c里面看，为什么偏偏UART1比其他两个口多了一句话 serial1.int_rx = &uart1_int_rx;
先屏蔽了编译通过。

烧写启动显示shutdonw，调试输出内容：
```RomBOOT
>Start AT91Bootstrap...
jump to RTT...
pit_rate=6208000HZ
PIT_MR=0x0300f27f

基本情况如上，有什么解决的思路建议吗？
