前提环境：开发板上电后，JTAG模式启动，SD卡已烧写系统文件，JTAG 和UART已连接主机
首先 下载驱动Linux_3.x.x_4.x.x_VCP_Driver_Source.zip，网址https://www.silabs.com/developers/usb-to-uart-bridge-vcp-drivers
编译安装
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中执行 dmesg | grep tty
dmesg | grep tty
[ 0.077306] printk: console [tty0] enabled
[ 11.762257] usb 1-9: FTDI USB Serial Device converter now attached to ttyUSB0
[ 11.765588] usb 1-10: cp210x converter now attached to ttyUSB1
[ 11.766179] usb 1-10: cp210x converter now attached to ttyUSB2
[ 11.766630] usb 1-10: cp210x converter now attached to ttyUSB3

[ 2938.964674] usb 1-9: FTDI USB Serial Device converter now attached to ttyUSB4
然后执行 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中点击 Window, Show view如下图，不知道为啥软件界面不能截屏
打开Vitis Serial Terimal自带的串口工具
点击右上角的加号，Port输入框输入/dev/ttyUSB0，Connected to: Serial(/dev/ttyUSB0,115200,0,8)提示连接成功
（输入ttyUSB0不行，输入别的也不行，都试过了）
这样就可以执行开发板上的命令了。类似于远程连接ssh了
