前提環境：開發板上電后，JTAG模式啟動，SD卡已燒寫系統文件，JTAG 和UART已連接主機

?

首先 下載驅動Linux_3.x.x_4.x.x_VCP_Driver_Source.zip，網址https://www.silabs.com/developers/usb-to-uart-bridge-vcp-drivers

編譯安裝

make cp cp210x.ko /lib/modules/<kernel-version>/kernel/drivers/usb/serial insmod /lib/modules/<kernel-version/kernel/drivers/usb/serial/usbserial.ko insmod cp210x.ko

然后Terminal中執行 dmesg | grep tty

dmesg | grep tty

然后執行 ls -l /dev/ttyUSB*

ls -l /dev/ttyUSB*
crw-rw-rw- 1 root dialout 188, 0 11月 28 13:02 /dev/ttyUSB0
crw-rw---- 1 root dialout 188, 1 11月 28 13:02 /dev/ttyUSB1
crw-rw---- 1 root dialout 188, 2 11月 28 13:02 /dev/ttyUSB2
crw-rw---- 1 root dialout 188, 3 11月 28 13:02 /dev/ttyUSB3
crw-rw---- 1 root dialout 188, 4 11月 28 13:02 /dev/ttyUSB4

?

在Vitis中點擊 Window, Show view如下圖，不知道為啥軟件界面不能截屏

打開Vitis Serial Terimal自帶的串口工具

點擊右上角的加號，Port輸入框輸入/dev/ttyUSB0，Connected to: Serial(/dev/ttyUSB0,115200,0,8)提示連接成功

（輸入ttyUSB0不行，輸入別的也不行，都試過了）

這樣就可以執行開發板上的命令了。類似于遠程連接ssh了
