MSP432E401Y: UART example "uartecho", change desired USB to target side of Launchpad MSP-EXP432E401Y

Part Number: MSP432E401Y
Other Parts Discussed in Thread: MSP-EXP432E401Y

I am trying to build the “uartecho” example for ti-rtos for from the target USB on the Launchpad board. My goal is to flash the target device using the XDS110 side of the Launchpad then run the code example using the target USB with XDS110 disconnected. Can you help with what it is I need to do get the .syscfg file configured correctly?

    Hello,

    So it sounds like you are just trying to flash this example project to the lauchpad like normal, correct?  That should be fairly straight forward.  Just import and download it.  

    But what are you wanting to do with the 2nd half of this question?  Are you just trying to use the back-channel UART built into the XDS110?  I believe this is how this example is already written.  

    Thanks,

    JD

    The example currently uses the XDS110 side of the board to flash and execute the example. I want to use the target side for execution. Steps outlined below.

    1. Flash drive by connecting to XDS110 side of the MSP-EXP432E401Y Launchpad board.
    2. Disconnect USB from XDS110 side of the MSP-EXP432E401Y Launchpad board.
    3. Connect to target side of the MSP-EXP432E401Y Launchpad board.
    4. Establish comms using terminal application.
    5. Type characters using host keyboard and look for echo in terminal window.

    Hello Lee,

    I still don't exactly follow.  The Launchpad has the XDS110 side and the Target MSP432E4 side.  When downloading the example, the XDS110 programs the target side of the board.  Then, when running the example, it does use the XDS110's back-channel UART as a UART-to-Serial port bridge.  

    So, you are asking to program the example, then disconnect the XDS110.  This is fine, but how are you wanting to connect the MSP432E4 to the PC?  Do you have another UART-to-Serial bridge?

    Thanks,

    Currently the example executes thru the same USB connector that it gets flashed by. I want to be able to flash it then run it on the opposite USB connector as in the attached image. How do I set up the  uartecho.syscfg file to do this?
