usbutil: unable to find a device matching 0451:f432

Recommended Posts

Hi, Im not total noob.  I did use old energia and Launchpad 2553 on this machine years ago and was good.

Bought new LP and got new Energia recently.  It wont upload. I get the

usbutil: unable to find a device matching 0451:f432   

error message tried everythig for two evenings.

 

COM8 only shows,  WIN7 pro 64 bit,  I loaded the additional driver,  USB for the MSP430 UART shows and is said to be working in  device manager.

Bit lost really - did not want to send the units back to Farnell.

 

Any clues  -  Steve  UK

Hi, I had the exact same problem. I fixed it by editing a file according to:


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

This is posted on the TI forum here:

https://e2e.ti.com/support/microcontrollers/msp430/f/166/t/580238?tisearch=e2e-sitesearch&keymatch=energia 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"

I solved the problem by following these steps exactly:

  1. copy <energia directory>\hardware\tools\DSLite\DebugServer\drivers\MSP430.dll to <energia directory>\hardware\tools\msp430\bin\
  2. edit <energia directory>\hardware\energia\msp430\boards.txt an change the 2 occurrences of rf2500 with tilib
  3. 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:

Hi NexNerd      I made tha changes,   in the TXT file there were maybe 4 or 5 instances where I swapped to tilib - especially for my listed board. Plus moved the dll across.

I get the same as before.   In enegia app, Tools Programmer  -  DSLITE is selcted is this ok (i tried the 2500 too)  I only have com8 acive with the board connected. (on any of my 3 usb ports on laptop.)

I get the same eror message even if I dont have the board connected!  Its like the code cant find the USBUtilites so the compiled code has no way of getting to my USB ports.

I guess at the very least it makes me thankful when a dev board does actually work!  I have a love/hate relationship with this crap.

Thanks for helping

Sorted.

 

I read the detail in the supplied link from yourself.

I ASSUMED that loading the latest Energia gave all of the best bits and so will be up to date.  Not so.

In board manager,  the MSP 430 box, at the end of the first line has INSTALLED showing -  I ASSUMED that this update had downloaded and INSTALLED.  It had - but the shown Version is just the one YOU have installed.  It does not show the other more recent versions which are available and may contain the fixes you need.

To see what is available Click on the Blue text More Info - I had two more versions "in the wings" - I selected the one with the highest rev No.  and clicked update or Istall cant rem which.

 

After about 3 mins it was all in.  restarted and I got a blink program,  Im back in 2012 woop.

Hope this helps.    I must trawl through all of the other updates that have not installed in there too.  :.(
