Executables selected for download on to the following processors doesn’t exist or incorrectly specified. Do you wish to ignore them and proceed?
1. microblaze_0

其实根本就不是MicroBlaze找不到，而是程序根本就没有编译出来！

仔细看一下编译时的输出信息：

希望我今天分享的这篇文章可以帮到您。

里面有一个error，说是BRAM空间不够了，编译失败。连elf文件（程序文件）都没有生成，当然就无法运行！

把BRAM的空间改大后，编译成功了，程序就运行成功了。

程序运行成功后，如果串口没有输出，检查一下Block Design里面Uartlite波特率设置的对不对。
