microblaze 串口调试

matrx2010

初学EDK参考网上的例程写了一段程序

  /*till uart FIFOs are empty */
  while(!XUartLite_mIsReceiveEmpty(XPAR_RS232_BASEADDR))
  {

    XUartLite_SendByte(XPAR_RS232_BASEADDR, c);
    switch(c)

编译后报出这样的错误

网上说是没有链接到库，是指没有generate libraries and BSPs吗？但是编译前我有生成库的，请高人指点

那位高手做过这方面的工程，指点一下，小弟不胜感激

microblaze里使用中断外设的话，一定要用中断控制器吗（只有一个中断）？

zkf0100007

必须要的

那前辈知道我上面的程序那里出错的了吗？

zkf0100007

你都到了编译这一步了，generate libraries and BSPs会自己做的，查一查吧，不会是你硬件没添加这个IP，编程时又引用，那肯定就不行了

不知楼主使用的EDK是那个版本，高版本的EDK已将XIntc_mMasterEnable等等的中间的m取消，变成XIntc_MasterEnable

我用的是EDK12.2，果然是这个问题，6楼太强大了！

看信息是没找到XIntc_mMasterEnable' 这些函数

应该是有些头文件没有包含吧
