Xilinx Vitis 2020.1运行C程序时提示找不到microblaze_0
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：

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。
