'No USB FET was found' error

Other Parts Discussed in Thread: MSP430G2553, MSP430F1612, MSP-FET

Every few days I start getting a 'MSP430: Error initializing emulator: No USB FET was found' when I build my projects, this problem lasts for a few more days until it spontaneously resolves itself. When this happens, Windows will report it as an unknown device with an error code of 43. I can't test building this on multiple computers or multiple launchpads at the same time. I had a revision 1.4 in the past which had the same problem.

 

Processor:MSP430G2553

Launchpad: MSP-EXP430G2 Rev. 1.5

CCSv5.3.0.0.00090 

Windows 7 x64

Fixes attempted:

Multiple USB cables and multiple ports some with and some without hubs 

Reinstalling CCSv5 with and without USB attached

Rebooting with and without USB attached

Replacing the MSP430 processor

  • I have solved this problem in the past by going to:

    Project->Properties->General

    Change the connection from USB1(Default) to USB2 then build project.

    Go back and change properties to USB1 again and build project.

    This has worked temporarily in the past.

    Disclaimer: It does not always stay fixed.

  • Hi Brian
    Could you can make sure your Device manage in first?

    And Cary, 

    I had the I2C test experience with two LaunchPad in the same time.

    You can open 1st CCS window and link to USB1.

    And then open 2nd CCS window and link to USB2.

    It' can work normally. 

  • I am a Vissim user, and i get this same error. However i may have damaged my debugger through a high voltage. Can anyone tell me which component to replace on the launchpad to eliminate this problem.

    Launcpad+2553 chip has Spy-by-wire system, still the Vissim doesn't recognize the JTAG chip...

    Basically i want to know what component gets damaged if a high voltage comes on the micro-USB slot. High voltage i'm talking about here is around 18V tops.

    overvoltage may have damaged teh TUSB chip which is directly connecte dto teh USB connextion. It also may have damaged the voltage regulator that converts teh 5V from USB down to 3.3V for the LaunchPad. If htis was broken, the full overvoltag emay have been applied to the rest of the LaunchPad, amagin the MSP430F1612 which does the actual JTAG programming, or the I2C memory chip that contains the firmware for the TUSB.

    While each of these components can be replaced, the 1612 is mroe expensive than a new LaunchPad, and for the others, the saved money ($5 for a new LaunchPad) isn't really worth the effort. Especially since you don't know beforehand which parts are broken. (well, it could be figured out, but since you had to ask at all, I guess, without a very detailed explanation, this would be beyond your current skills.)

  • Hi

    I have a launchpad MSP-EXP430G2 Rev 1.5.  I would like to code it using ccsv5 on Ubuntu 12.04.  when I try to debug it (hit the debug button on the toolbar I get the the above error: MSP430: Error initializing emulator: No USB FET was found.  I know for previous versions of ccs did not support launchpad; has this changed for ccsv5?

  • Hello all,

    I am also facing the similar issue with "MSP-FET FLASH EMULATION TOOL". 

    I already had an  "MSP 430 FET UIF USB DEBUGGER" which worked well. As i was in need for another debugger i have placed and order with TI's official site and i was sent this particular device, which is in total black color and the usb type in device is also seems to be changed. The device was labeled as " Serial : 1401003FA" . Also on the front panel it says "MSP-FET FLASH EMULATION TOOL"

    I tried to use with the FET PRO LITE software  v3.2 which was working in VCP mode with old debugger which was working fine, Now when i connect my new debugger i can not flash my device. 

    When i try to launch with the CCS v4 ( I cannot upgrade to other CCS versions due to application limitations) i am facing an issue with "Error Initializing emulator, no usb-fet was found" message. 

    where as i could debug with my old debugger, Can any one suggest me what needs to be taken care to make work with my new debugger.

    Regards

  • Raga Ranjan, I think your FET s/w is new but CCS version is old. Try installing latest CCS. Hope it helps.

  • Hello Shishir,

    Thanks for your promp response,

    I am using CCS v4 for old debugger and also tried with new debugger, As i mentioned in my previous post i can not upgrade to CCS due to some constraints. Apart from that, i also tried with other PC which has CCS V5.4 with the new debugger, but still facing the same issue!!!

    Kindly suggest me any workaround for this!!!!

  • In my case , i resolved it by using the original cable from launchpad .. other cable does not work i don't know why.

  • Processor:MSP430G2331

    Launchpad: MSP-EXP430G2 Rev. 1.4

    Code Composer Studio

    Version: 6.1.3.00034

    Windows 10 x64

    I'll be adding my observations on this same problem I'm having too.

    Sometimes I get the error message in the CCS console:  MSP430: Error initializing emulator: No error

    That one is particularly helpful!

    It seems if I unplug the launchpad, close CCS, reopen CCS, plug in the launchpad, I can load and debug/run once.  If I try to load and debug after that, I often get either the ".. no error" error or "no usb fet found" error.

    But sometimes I can load and run repeatedly.  The lack of repeatability makes the possibility of troubleshooting pessimistic.
