CCS/MSP432E401Y: MSP432E401Y

Part Number: MSP432E401Y
Other Parts Discussed in Thread: ENERGIA,

Tool/software: Code Composer Studio

Hi,

I am trying to use MSP432E401Y launchpad with CSS cloud for programming. To get started, i connected my board with the computer via USB cable and downloaded appropriate COM port drivers. Once done, i opened up "Blink" example from Projects->New Energia Sketch. After giving appropriate project name i selected "MSP432E(32-bit) Boards v5.19.0" as the Device and "LaunchPad w/ msp432e (120MHz) as specific board. Following that i opened up an example sketch under Built-in Examples-> 01. Basics-> Blink.ino

After that, i build the project and then select appropriate COM port from the tab, Target-> Connect COM port, and then press run. This shoots up an error message and i can't seem to get around it. The error is as shown below:

Unable to connect to LaunchPad w/ msp432e (120MHz).
Please unplug and re-plug the USB connection and try again.
Stellaris In-Circuit Debug Interface/CORTEX_M4_0
Error connecting to the target: Unable to communicate with the device. Please check your connection.

Can you please help me fix this issue. I tried looking up online for help but couldn't find much. 

Regards,

Sakib 

  • Sakib,

    That looks odd.  The board has an XDS110 debug probe on it and not a Stellaris In-Circuit Debug Interface.

    If you go to dev.ti.com and let it auto detect the board with the little slide out window on the left does it detect the board ok?  It should display something like this:

    Note that it may prompt you to install cloud agent. That will be needed by CCS Cloud anyway.

    Also please make sure to connect the USB cable to the end of the board furthest from the Ethernet connector.  That is the USB port that is used for the onboard debug probe.

  • John,

    I did install cloud agent and let it auto detect the device. It was able to recognize the launchpad as seen below

    The device manager detects the following COM ports as well

    However, I still get the same error. In fact, I used a second MSP432E401Y launchpad and got the same result.

  • Sakib,

    Your LaunchPad looks good.  I think something is wrong with the Energia integration as I can reproduce this problem.  When I follow the same steps as you I can see that the project gets generated for TM4C1294

    I will have to file a bug to track down what is going on there.

    To get going you could import an example from the SimpleLInk MSP432E SDK.  

    If you go back to dev.ti.com.

    Click on the Resource Explorer tile.

    Then click the button to use your board. That will filter the content to just that which is relevant to your board.

    Then you can browse the examples in the SimpleLink MSP432E SDK.  The pwmled1 example is basically a fancy Blinky.

    You can click on the import to IDE button at the far right to import it into CCS Cloud.  I would close your browser tab that has CCS cloud already open first.

    You can then click the bug button to build and debug it.  It takes a little while to build as it has to build the TI RTOS kernel first.  It may also want to update the firmware on the debug probe.  IF it does want to do an update click on the update button but then afterwards it will say that it failed to launch the debug session. Just click ok and launch again and it will work.

    Regards,

    John

  • Note that I have filed TICLD-3029 to track the issue with the wrong device being selected when creating new Energia sketches.
