CCS/MSP-EXP430FR6989: Error initializing emulator: Interface Communication error

Part Number: MSP-EXP430FR6989
Other Parts Discussed in Thread: MSP430FR6989, , CCSTUDIO

Tool/software: Code Composer Studio

Hi,

I have an MSP430FR6989 Launch Pad  (MSP-EXP430FR6989), I am writing a program in CCS v8.2.0, the Launch Pad is connected to my PC through a USB cable.

When I try to debug my program and download into the Launch Pad, I get this Error: "MSP430: Error initializing emulator: Interface Communication error".

My OS is Windows 10 Pro 64 bits.

Checklist of the things I have done:

- Replaced the USB cable with another cable.

- Restarted the laptop

- Deleted the .metadata folder

- Installed updates (Help->Check for Updates).

- Allowed ccsstudio through my firewall

All of this didn't work, kindly advise me on this issue.

Thank you in advance.

    Are you able to debug any out-of-the-box example on any other MSP430 LaunchPad?
    During CCS installation you need to select debug probes you will use later on.
    To do that just rerun CCS installer.

    I have only one MSP430 Launch Pad, and the code written in the IDE is my code.
    It worked fine before, but now all of a sudden this error keeps popping up.

    I will uni-install it, and install again, and see what happens

    Farat,
    try to run and debug an out of the box example.
    Be aware that you are dealing with an ESD device.

    What do you mean by an out-of-the-box example? What I understood by this statement is to write my own code compile it, download it into the Launch Pad, and debug which I did.

    Electro Sensitive Device, I am powering it through the USB cable provided by TI.

    [EDIT]

    I uninstalled and installed ccstudio v8.3.0 again, opened CCS App Center and installed MSP430 Compiler v18.12.0. Built my project, and when I tried to debug it, it gave me the same error.

    ESD device needs careful handling: en.wikipedia.org/.../Electrostatic-sensitive_device

    Check connection with a debug probe using "Verify" button:

    Hey Forat,

    Has the board worked before? Also, can you check that the jumpers on the launchpads programming header are connected correctly according to the Launchpad users guide that Tomasz linked? (Basically, that they are just populated vertically across the debug connections?)

    If that looks fine, Can you try restarting CCS and/or your PC?

    Thanks,
    JD

    Hi Tom,

    I connected my Launch Pad to the computer. Opened properties -> General, Connection: TI MSP430 USB1 [Default], I pressed identify and it gave me the following error:

    MSP430: Error initializing emulator: Interface Communication error.

    Hi Forat,
    could you show us content of your "connections" folder?
    In my case it is under: C:\ti\ccs830\ccsv8\ccs_base\common\targetdb\connections

    Hi JD,

    Yes, the board was working fine, this problem is new. the jumpers on the launch pad are connected properly as you can see on the image below

    Hey Forat,

    Any luck getting this board to work?

    Everything you've posted looks alright, so I'm leaning towards something happened to the hardware. Maybe ESD or some other event.

    If still not working, I'd recommend replacing the launchpad. If a new launchpad works, then we can assume a hardware issue.

    Thanks,
    JD
