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
其實根本就不是MicroBlaze找不到，而是程式根本就沒有編譯出來！
仔細看一下編譯時的輸出資訊：

裡面有一個error，說是BRAM空間不夠了，編譯失敗。連elf檔案（程式檔案）都沒有生成，當然就無法執行！
把BRAM的空間改大後，編譯成功了，程式就執行成功了。
程式執行成功後，如果串列埠沒有輸出，檢查一下Block Design裡面Uartlite波特率設定的對不對。
