求教edk串口调试问题 串口, edk, 求教, 调试

lin0cn

我是想通过串口接受数据 暂存在buffer 然后将数据发回

自己搭了一个串口电路 写了代码如下：

#include "xparameters.h"

#include "stdio.h"

#include "xutil.h"

#include "uartlite_header.h"

#include "xuartlite.h"

#include "xuartlite_l.h"

#define XPAR_RS232_BASEADDR 0x40600000
int main (void)

{
   Xuint32 i;
 
   Xuint8 buff=0;
   
   while(1)
   {
       
           for(i=0;i<900000;i++);
          
           buff = XUartLite_RecvByte(XPAR_RS232_BASEADDR);

           XUartLite_SendByte  (XPAR_RS232_BASEADDR,buff);
  
    }
}

在XMD Debug Option中 cnnection type 选择的是stub, Advanced Option：serial，然后点击Launch XMD，却说：“unable to open serial port com1
                             closing serial port”

不知道是我程序有问题 还是设置问题

请大虾指教 万分感谢！

后面调试的时候 我已经改了debug的方式 已经在xmd时，选择on-chip hardware的方式

但是 在update bitstream时 出现：

WARNING:NgdBuild:452 - logical net

WARNING:NgdBuild:452 - logical net

在launch xmd时，有警告：

verify if fpga bitsteam was downloaded and done pin wen high
