UART on F2806x ISO Controlcard not working

Other Parts Discussed in Thread: CONTROLSUITE

Running the sci_echoback example from controlsuite, Im having issues writing to the MCU. I am running it in CCS using the ISO debugger on the controlcard.

When the project is run, it writes to the terminal without any problems:

Hello World!

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

Enter a character:

But when writing a character the data is never received by the MCU.

Both taps on SW3 is set to "ON"

    Hi Anders,

    It sounds like the controlCARD is set up to receive (SW3 is configured correctly).  However, it isn't receiving.

    Can you make sure the baseboard isn't creating contention on GPIO28?

    Assuming that you are using the Docking Station baseboard, can you try to hold the xds100v1 (on the Docking Station) in reset?  You can do this be placing a jumper on the Docking Station's J8.  This may enable your Windows PC to have fewer concerns by forcing it to only have one xds100 UART to talk with.


    Thank you,
    Brett

    Hi Brett.
    I managed to solve the problem.
    I was running on the HVMotorCtrl+PfcKit.
    On that kit, you have to use the JP1 USB connector for SCI communication.
    So disabling the SCI on the controlcard by moving the SW3 position 2 to off, and adding a USB cable to JP1, solved the communication issue.
