CCS/MSP430FR6989: mps430fr6989

Part Number: MSP430FR6989
Other Parts Discussed in Thread: MSP-EXP430FR6989, MSP-FET, EK-TM4C123GXL, TMP100

Tool/software: Code Composer Studio

I’ve been using MSP430fr6989 launch pad for some time, ordered on 6/8/2018, order number 1863789.

It’s been having some problem at the USB port, repeatedly forcing me to reconnect device. Now, it appears that it won’t be connected to PC anymore.

Is this part carry some kind of warranty, or do I need to repurchase the launch pad?

Thank you in advance for your support and assistance in this matter.

  • Hi Kwang,

    Could you confirm for some details of your issue:

    1. Did you connect the MSP-EXP430FR6989 with your PC successfully?  As well as programming and debugging for your launchpad?

    2. "It’s been having some problem at the USB port, repeatedly forcing me to reconnect device." Did you try on another PC to check if there is same issue to force you to reconnect device?

    3. Could you help to check with below guide for connecting with PC? 

    Connect the LaunchPad using the included USB cable to a computer. A green power LED(LED102) should illuminate. For proper operation, drivers are needed. TI recommends installing these driver by installing an IDE such as TI's CCS or IAR EW430. Drivers are also available at .

    4. Please check whether below COM port could be found on your Windows PCs->Device Manager-Ports(COM & LPT). The COM number would be difference.


  • Mr. Wei,

    Thanks for your quick response.

    Since I received this Launchpad last summer, I've been using this Launchpad almost daily. I do have 4-5 different Launchpad acquired in the past, but never find any of previous ones (models) suitable to my needs, hence not really committed myself to become familiar with it. Something in this 6989 Launchpad triggered my interest into micro-controller realm, that I am really focused to work with it nearly every day.

    The frequent error message shows,

    Error initializing emulator:

    No USB FET was found,

    that forces me reboot/re-establish PC connection by removing and reattaching USB cable to the Launchpad.

    The blue LED at the emulator side illuminates when USB cord is attached, indicating that this PCB does receives power, but data is not being transmitted, hence the message noted above. Com port on PC’s device manager indicates valid connection to this Launchpad when it’s working as intended, but disappears during times of error message noted above flashes. There is no issue running the Launchpad, as it receives power; the problem exists on continuity of the data pins on the USB, either at the physical USB connector, implemented TI’s EasyFET chip, or intermittent short/open circuit development within PCB trace, or perhaps but not likely, unstable I/O ports on the MSP430 chip itself, I don’t know.

    It’s important to note that, this issue does not happens all the time, but it’s so frequent, becoming annoying distraction; it makes me practically impossible to work with this Launchpad. This issue becomes more pronounced during debugging process, when CCS (IDE software) lost its execution pointer to source code, that I must re-start, walk through all steps to place the program execution pointer to last source code locations, sometimes, and often, doing this all this process over again and again.

    To answer your question item (3), I do not have a spare PC to validate USB on the PC side, but I have no issue connecting other USB devices, such as Garmin GPS, or even an Android phone device. Android device sometimes, but not as frequent as this Launchpad, replicate similar phenomenon, that is, losing data commutation while data is being transmitted between phone and PC. I do my best to avoid my time engagement with Android garbage. Com port on PC side indicates the valid connection to this Launchpad when it’s working as intended, but disappears when error message noted above flashes.

    Currently, I’m in the process of writing/debugging source code for this Launchpad, and you, as a programmer, will probably concur that its worst thing that can happen to any programmer to encounter.  I really like my unstable Launchpad to be replaced as soon as possible, as there's nothing worse than having unreliable hardware and having to write a code.

  • Hi Kwang,

    Thanks for your interesting in the MSP430 MCU. I'm sorry to hear your failure and as an programmer I fully understand your feeling.

    I can't confirm the root cause of your issue as it would come from emulator hardware, emulator firmware, PC diver or the IED files.

    But could help to confirm whether the other LaunchPads work well on your PC?
    Also, which IED you used to download and debug? Did you update the IDE with the latest version?

    Could you try to use other IED, such as IAR or TI CCS cloud version(https://dev.ti.com/ide) to confirm if the issue comes from the IDE files?
  • Hi Kwang,

    I'm sorry to miss your information of the CCS IDE that you're using in your previous reply. Please ignore my question about the IDE.

    I've received the message that you called our customer support center. I'm sorry to know your difficulty for accessing to the E2E forum. I've already called your phone number several times but haven't reached.

    First of all, you mentioned the "Blue LED" was indicating that the Lauchpad is powered. Could you confirm it is the LED102(which should print besides the LED)? It should be a green LED, so I just want to make sure we are talking about the same indicator LED.

    I would like to give you my judgement about your issue as well as some suggested actions, based on the information I got from your previous reply.

    The error message "Error initializing emulator: No USB FET was found" should be telling you that the CCS had lost the connection with the eZ-FET on you Launchpad. It could be caused by below issues:

    1. The emulator driver issue on your PC, which may be caused by:

    • The driver files was damaged by any unexpected operation when you were debugging. For this situation, I would suggest you to update your CCS to the latest version to get the latest emulator driver, or even re-install the latest CCS, which will re-install the latest emulator driver. So, if you could, please do this to refresh the programming software tool on your PC. 
    • The COM port was conflicted with other OS threads on your PC. I'm not an expert about the PC OS. But at common sense, your PC OS managed all the threads and port. If the OS is handling some conflict to terminate the COM ports for eZ-FET for the moment, the CCS will also disconnected with you launchpad. This is why I want you to try on another PC.

    2. The hardware connection between you PC and the eZ-FET has some issue:

    • The USB cable you used is not stable for connection. You could change a new USB cable to confirm this.
    • The Launchpad is broken. You need to replace your Launchpad with a new one if it is for this reason. Or you can jump the eZ-FET of another Launchpad, if you have, to the FR6989 circuit by the SBW_RST/SBW_TST/3V3/GND on J101.
      • The USB connector(J102) on the Launchpad has some issue to get a stable connection. You said you used the Launchpad daily, so the connector may has some issue. The green LED102 should be off when your error occurred. Please confirm this.
      • The eZ-FET circuit on you FR6989 Launchpad is broken. If the power circuit of eZ-FET has issue, the green LED102 should be off when your error occurred. Please confirm this. If the data circuit of eZ-FET is broken, the red LED101 will always be off, while it should flash when data is transmitted.

    I know it's difficult for you to access to the E2E. I will send my cellphone number to your email as well as our customer service center in case you have chance to call me to discuss your issue.

  • I need a replacement board.
  • Hi Kwang,

    Do you mean that the eZ-FET has hardware issue as I listed on 2# of previous reply? Could you share me the checking result for my comments of 2#?

    If you make sure the hardware is broken, you could do the replacement by follow method:
    1. If you have another MSP430 Launchpad, you can jump the eZ-FET of another Launchpad to the FR6989 circuit by the SBW_RST/SBW_TST/3V3/GND on J101. You could also use a MSP-FET to jump to the FR6989 Launchpad if you have one.
    2. If you only have this broken Launchpad, please contact the seller, you could contact TI customer service center if you bought from TI, to check if they can change a new one for you. Or you may need to buy a new one.

    You should receive my email with my cell-phone number. Please feel free to contact me for further question if you can't access to the E2E forum.
  • No more nuisance message.

    I've requested this issue to be elevated, so that someone who has knowledge of the Launchpad can assist me.  I'd like this defective board to be replaced.

  • Hi Kwang,

    I'm sorry that you have to replace a new board for the work.

    I know you have called our Customer Support Center for your issue and I will also tell them about your request as well as the issue information we talked here. I hope you could get a new board soon to go on with your work.

    I would like to click the "TI Thinks Resolved", which only means to close the threads on my internal tracking list temporarily,since you've already move to the board replacing processing. You don't need to click verified if you don't get a replacement board to solve your problem. But please feel free to come back here or create a new thread any time if you got any further technical question about the MSP430 devices and tools. Also you can call me for some urgent issue.  

  • wow,

    how many ways is there to saying, Ï have defective card that needs to be replaced...."

    I'm not sure how else can I phrase it so that I can get some help from the manufacturer of this launchpad.
  • Hi Kwang,

    I'm sorry you have to get a replacement board for your work.

    Do you mean that you have already contacted TI customer support center for the replacement?

    If not, please follow the return policy to return it and get another one.

  • I was told that you (TI engineer through this forum ) can decide if the board is bad, hence send out a replacement board under warranty.

    I really need the replacement board, as I cannot do anything with what I have now.
  • Hi Kwang,

    Yes, I had talked to our customer support center and they had contacted you for your information by email last week. Please check your email inbox and reply it to let the request go ahead.
  • TI had no issue shipping product to recorded General Delivery address on initial order (Order Number 1863789), and later replacement order when other Launchpad (TIVA C, EK-TM4C123GXL) was found to be defective (THREAD ID:1-23B4H2G). I don’t know what is the issue of using General Delivery address, but if you insist to ship to a physical mailing address, please ship it to;

    Kwang Yi
    4115 Heiney Road, UNIT # 138
    INDIANAPOLIS, IN 46241-7209

    It’s been so long since this case was open, but I genuinely appreciate your decision to replace the damaged unit. Without fully functional board, I was leaning toward for search of different microprocessor manufacturer, hopefully one with prompt and experienced technical support staff, regardless my past time spent on this particular board. If you like to know what has gone wrong with defective board, please send the shipping label along with replacement product. In this way, we don’t need be wasting our precious time and resources with countless yet meaningless e-mail correspondences. Thank you for your assistance in this matter.

    In the meantime, for my on-going project, I need to acquire reliable ambient temperature and ambient light measurement. Review of data sheet on those sensors (TMP006 & TMP100 & ISL29023 & CM3218) suffice my need, but it’s always best practice to experiment and hence understand capability/pitfall of sensor modules, especially, if I’m planning to build a prototype PCBs. Can you help on this?
  • Hi Kwang,

    I will forward your information to our Customer Support Center and they will handle the replacement.

    For further technical problem with TI devices, please feel free to create thread on corresponding forum of E2E.
  • Thank you for your assistance.
  • I'm not sure if I'm still able to post after thread is closed.

    I have just one issue; I have not yet received the replacement board I believe TI claimed to send out to new address.

    Has the replacement board been shipped out yet?  If it was shipped out, can you provide the tracking number so that I can trace the shipment and retrieve the package when delivery man shows up.

    Thank you for your assistance in this matter.

  • Hi Kwang,

    Let me check with our Customer Support Center and feedback you then.
  • Thank you for your time and assistance.

    I can make one useful hardware using this micro-controller that I’m hoping all the time spent on this will be well rewarded.

    By the way, I’d like to order the BOOSTXL-SENSORS, but I’d like to take an advantage of free-shipping incentive. I believe TI will issue a free-ship code if I closed the thread.  I’ve closed this thread, hoping to receive free-ship code. Would you please look into this issue why I still have not received the code?

    Thank you.

  • Hi Kwang,

    Thanks for your interesting to the MSP430 device again.

    We have different kinds of forums on E2E for different type of issue. Here, in the MSP forum, I could only answer the technical question about MSP430 devices.

    But I have created a new thread for your issue on the "Site support forum" and there should be someone to check for your issue: e2e.ti.com/.../751556
  • Hi Kwang,

    As E2E is not the proper venue for resolving issue except engineering, design and debug discussions, I would like to send you private message inside E2E. Please accept my friendship request.
