Energia error 0451:f432

Other Parts Discussed in Thread: ENERGIA, CCSTUDIO, MSP430G2553

Hi all,

I trying Energia but am unable to upload. I'm getting the error:

usbutil: unable to find a device matching 0451:f432

I tried the common problems:

  • You have selected the wrong serial port. 
  • I have selected PORT12 as shown in the Device Manager.
  • Your launchpad is not connected to the USB.
  • It's connected.
  • You are using a usb power cord, not a data cord.
  • It's the one that came with the Launchpad.
  • There is bug Mac OS X in the driver that caused the Launchpad to be disconnected. Unplug/plug the LaunchPad to make Mac OS X recognize it again. (if you have programmed the Launchpad with code that is writing out serial data, hold the reset button on the launchpad for a few seconds when you connect the usb...then your mac should be able to upload again)
  • Note Energia will recognize your launchpad once it is connected to the usb. 2 extra lines will appear in the tools->Serial Port menu
  • I'm using Windows10.

I have CCSv7.2.0 and Energia 1.6.1oE18 installed.

Is there a solution/workaround?

thank you.

    Hi Scott,

    Are you able to communicate with the board using CCSTUDIO? What LaunchPad variant are you using and is it properly selected in Energia?

    Regards,
    Ryan

    I answered my own question. For anyone else who has this issue, see:

    github.com/.../Common-error-messages
    e2e.ti.com/.../539487

    This is posted on the TI forum here:

    e2e.ti.com/.../580238 usbutil%3A unable to find a device matching 0451%3Af432

    Or you can search the TI forum using:

    "energia usbutil: unable to find a device matching 0451:f432"

    Speicific steps:

    copy <energia directory>\hardware\tools\DSLite\DebugServer\drivers\MSP430.dll to <energia directory>\hardware\tools\msp430\bin\
    edit <energia directory>\hardware\energia\msp430\boards.txt an change the 2 occurrences of rf2500 with tilib
    restart energia and you should be able to upload to the MSP-EXP430G2 with MSP430G2553.

    Apparently this is a known issue but there's some question about whether it's resolved using latest versions of the tool. The issue is also posted on github:

    github.com/.../12
