CCS/TMS320F28377S: SCI Echoback Example Terminal Not Working

Part Number: TMS320F28377S


Tool/software: Code Composer Studio

Hi,

I am fairly new to Code Composer Studio and I am having trouble viewing the terminal. I am using the sci_echoback_cpu01 example. Currently, the sample code is in my project. Whenever I debug and open my terminal to the correct COM number, the terminal say it is CLOSED. I assume that because it is running in Debug mode.

 

So how can I run the terminal while debugging? Is that possible? If so, can someone guide me on a step-by-step process? Please and thank you. 

George

    George,

    It seems that you have the UART Communication added in the target configuration file, is that so? That is not necessary for normal JTAG debugging, it is provided for a different use-case. 

    Open the target config file (.ccxml) and Delete the UARTConnection if there is one added. Then restart the debug session and try opening the COM port using the Terminal view.

    Thank you for replying AartiG! Now, I can open the terminal while debugging. Although, when I click RESUME button in Debug Mode, the terminal does not display any messages. Is there something that I missed? I am expecting the terminal will display:

    Hello World!

    You will enter a character, and the DSP will echo it back!

    Enter a character:

    After displaying the message, it should wait for me to put an input in the terminal. Also, I can't type anything in the terminal.

    I tried to follow this post and I set my SW1 ON: 

    e2e.ti.com/.../613540

    But, it did not work.

    George,

    Your last question about running the SCI Echoback example is more appropriate for the C2000 device forum. Could you please start a new post for that in the C2000 forum, as it will be easier to manage and keep the two questions separate.

    Since your original question with using the Terminal view is answered, I will mark this thread as answered. Thanks.
