MSP-FET Emulator Not Recognized

I recently purchased an MSP-FET Flash Emulation Tool (Digikey part number: 296-37897-ND).

I connected it to my PC, attempted to update the FW via the IDE (CCS) and was notified that the update failed and the device needs to be recovered. I then attempted to “recover” the device via the IDE and it fails every time.

The windows device manager does not recognize the device as it should.

Some things I have tried:

  1. Connected to another windows PC. No dice. That PC doesn’t recognize the device either.

  2. Using another MSP-FET product on the original PC. The other one works as expected. So to be clear this is an identical product connected to the same USB port on the same PC. One MSP-FET’s work and the new one does not.

  3. Updating via the “FET-Pro430” windows application.

Any assistance is greatly appreciated.

Hi @user171

This smells like: CCS/MSP-EXP430FR2433: "MSP430: Error: MSP-FET / eZ-FET recovery failed" firmware bricked? - MSP low-power microcontroller forum - MSP low-power microcontrollers - TI E2E support forums

Do you have the screen shot of your recovery attempt?

What OS are you using? Hopefuly just Windows and not thru a Virtual Machine (VMware/Virtualbox/etc…)

Try both USB3 and USB2 ports if you have them…


MSP430: Error initializing emulator: One of the connected MSP-FETs / eZ-FETs debuggers needs recovery. Select ‘Recover’ to start the recovery process. Note: Only one MSP-FET / eZ-FET debugger can be connected to your system during recovery.
MSP430: Error: MSP-FET / eZ-FET recovery failed

I am using Windows 10. No virtual machine.

As for the TI forum link you referenced, I agree this sounds like the same issue. It looks like the solution in that case was to install an older version of CCS and recover.

I will try this tonight and reply to this post.


I plugged the MSP-FET into a third windows PC with the same version of code composer installed, clicked debug on a random project and it updated the firmware on the device successfully. My device manager now recognizes the product.
