CCS/MSP-EXP430G2: MSP-EXP430G2 using MSP43G2553 and CCS7: "Error initializing emulator: No USB FET was found" on Windows 10 x64

Part Number: MSP-EXP430G2

Tool/software: Code Composer Studio

Hello everyone,

I have a problem flashing a MSP430G2553 MCU using my MSP-EXP430G2 Launchpad. The software I am using is Code Composer Studio 7 running on Windows 10 x64. I have been using this software completely without any problems in the past. However from time to time I started getting an error message lately saying "Error initializing emulator: No USB FET was found" during debugging, until the point that I get the error mesage every time I try to debug or flash the MCU. I also noticed, that since the time it shows the message every time, Windows connects to the device as MSP USB UIF Flasher but after let's say a minute, it disconnects and reconnects as an unknown device.

I have searched throughout the internet and this forum in particular and it seems that nothing helps. I tried to reinstall CCS several times, tried to reinstall the drivers for the launchpad but nothing helps. The MCU seems to be working normally because the previous code is still running in the MCU without any problem, when VCC is applied to the board. The USB cable should be okay too, as I am using the same cable without any problems with my camera. Is it possible that I fried the JTAG or anything on the emulator part of the board? Is the fault somewhat checkable? Like, can I detect any faults using a generic voltmeter? For this case I will also check the board schematic.

Thanks for any help.

Best regards,

Jan Hentschel.

    Hello Jan,

    Your description definitely appears to indicate an issue with the ez430 hardware. You can check the voltages between the MSP430F1612 and TUSB34 devices but a voltmeter will not relay much information concerning the communication lines. Do you have any other MSP430 LaunchPads to test with?

    Regards,

    I have detected the same problem, in the same conditions (MSP430G2553, CCS7, WIN10).

    Nope... That's the problem... I don't have any other Launchpads nor MCUs to test with and I need to finish my project in time. So I'm finding a quick solution to repair the Launchpad without the need to buy a new one. However buying a new one looks like the quickest possibility now, since the whole launchpad with G2553 is not that expensive.

    Regards,

    Okay... I tested the board today with my friend and it worked well on his Windows 7 x64 PC. So the problem might be in Windows 10 drivers. Any help on that?

    Thanks a lot.

    All low-level USB drivers are provided on the MSPDS tools page, support includes Windows 10 32/64-bit.

    So I tried to completely uninstall CCS and anything driver-related, reinstalled fresh new CCS with new workspace, installed the MSPDS tools page drivers and on the first plug of the launchpad into the USB I got the same reconnection as unknown device and "No USB FET was found" message.
    Any help now? I think it's related to Windows 10 x64 problem but I don't know what it could be. I might have even messed up proper uninstallation of everything I should but I am not sure what all should be deleted and I cannot find any article about that.

    Again, thanks for all your help.

    Regards,

    Jan Hentschel.

    Are you using a USB 3.0 port?  This has caused trouble with G2 LaunchPads in the past.  I've also attached an updated MSP430.dll which should be copied to <CCS_INSTALL_DIR>\ccsv7\ccs_base\DebugServer\drivers and might resolve your issue.

    MSP430.7z
