Vitis UART Serial communication for Zynq

[kbj1213]

Hi, I'm going through ug1209 (Zynq Ultrascale+ MPSoC:Embedded Design Tutorial) for Vitis 2020.1.

I'm doing it on Ubuntu.

When I tried to do what is on 34 page of ug 1209 (sending "Hello World" string to the UART0 peripheral of PS), my Terminal showed nothing.

I want to do UART communication by USB Type-A to USB Micro cable (Ubuntu PC to ZCU102 board)

(ttyS0 is jtag for FPGA configuration)

The following figure is my Serial Terminal Setting.

After I do run configuration, nothing happens on ttyUSB2 Terminal.

Is there anything I could try for debugging?

 Not sure if this will fix it since I don't run Linux, but try changing flow control to software (Xon/Xoff)

I had a similar terminal problem that was fixed when I did that, but yours could be something else.. Just something to try!

Thank you for your advice. I tried it in Vitis Terminal setting, but it doesn't work for 1) None 2) Hardware 3) Software flow control all....

Interesting.. Are you connecting to the terminal before or after you run the program? Is it possible you are just missing the string it is printing?

I connect to the terminal before running program.....

Well... I couldn't check whether I missed it.

Just..... resolved this problem by using other PC (windows)
