EVM430-F6736: Error: Could not find MSP-FET430UIF on specified COM port : (Initialize) , port=USB, version=0xffffffff

Part Number: EVM430-F6736
Other Parts Discussed in Thread: MSP-FET, MSP430F6736

Hi all,

I work on an EVM430-F6736 energy meter module.  I have downloaded the slaa517e zip file and have rebuilt emeter-toolkit ad emeter-ng projects.

I use an MSP-FET430UIF User-Debug-Interface to download the application into the module.

But when I download and debug, the process ends abruptly flashing a  'Fatal error' message. The following error message has been logged:

"Could not find MSP-FET430UIF on specified COM port : (Initialize) , port=USB, version=0xffffffff"

Could someone please help?

Thanks,

Asha

    Hello Asha,

    Thanks for your post. I'm sorry that you're having an issue with the MSP-FET430UIF. Actually, the MSP-FET430UIF is not recommended for new designs (NRND), and instead we're recommending users to upgrade to the newer MSP-FET. For this specific issue, I suspect you may be using a USB3 port on your PC or you're not configuring the jumpers on the EVM correctly (refer to SLAA571).

    Rather than use our legacy Energy library (mentioned in SLAA571), we're recommending users to use the newly released Energy Measurement Design Center (EMDC) and software library. The EVM430-F6736 is an excellent platform for single-phase development and is supported by EMDC. There are several EMDC example projects that you can open in EMDC for this EVM. Then, you can easily generate the code, import it into CCS, and program the EVM. After making the high voltage (follow the instructions and safety precautions in SLAA571) and communication connections (refer to the EMDC Technology Guide), you can easily connect and view results.

    We'll be releasing a new EMDC version soon with IAR and Rogowski support that includes an Out-of-Box Example section and updated communication connections. Please refer to the attached updated tables below rather than those in the v1.20 Technology Guide. Also, I've included a high level diagram of the communication connections for your reference.

    Please let me know if you have any questions.

    Regards,

    James

    Thank you James for your input.

    Unfortunately this did not resolve my issue.
    I am not using a USB3 port on my PC.
    Also, I have verified the jumper configurations.

    Could you spot any other possible reason for this issue?
    Please note that I started facing the issue out of the blue. It was all working perfectly until one fine day.

    Thanks,
    Asha

    Are you using IAR or CCS? I suspect there was a recent update to the debug stack behind the scenes or the firmware on your MSP-FET430UIF has an issue. To get started, I would recommend updating either IAR or CCS to the latest version, plug your MSP-FET430UIF into your PC, and see if you can update the debugger's firmware.

    Regards,

    As a follow-up, there have been several instances where certain motherboards/chipsets/drivers on gaming computers/accessories cause these types of issues. Take a look at the following threads for some workarounds that may help you.

    Thank you James.

    I had been using IAR. But as per your suggestion, I am currently migrating to EMDC and CCS.

    I have the following queries:

    1. When EMDC and CCS are being used, will I be able to use the MSP_FET430UIF interface to download the executable into the hardware(EVM430-F6736) ?
    Or should I use the HID bridge and isolator? 

    2.  To try out if the MSP_FET430UIF interface works, I tried debugging and downloading the executable from CCS. I used the default configuration for this EVM while generating code in EMDC.
    However, the LCD display of the EVM became blank upon this exercise. Could you please troubleshoot this issue?

    3. Is it possible to edit the code in CCS to add a few functionalities that I would like to try? If so could you please give a small example? It would be really helpful.

    Thanks,

    Asha

    Excellent! Please use the latest version, v1.30.

    Don't use the MSP-FET debugger when the EVM is connected to high voltage. Configure the jumpers to allow the MSP-FET to provide power to the EVM, make sure the JTAG jumpers are configured to SBW, and you can then program the MSP430F6736 device with the compiled binary. The HID bridge and isolator are used for the communication only. Refer to the high level block diagram in the v1.30 Technology Guide or in the linked thread directly above.

    Yes, EMDC does not support the LCD natively and will be blank when used with EMDC. This can be added later to the application code and will hopefully be supported in a later EMDC release. For now, you can view the results in the EMDC GUI. If LCD support is a must for you, you can reference the legacy Energy library code.

    Absolutely! Keep in mind that we aren't releasing the source code for the EMDC software library, but the API guide does cover the EMDC APIs. You can definitely add application code, which is the goal behind EMDC - to let users focus on application code rather than implementing or fully understanding the metrology code.
