CCS/MSP432P401R: Factory Reset using MSP-FET and MSP-FET-432ADPTR

Part Number: MSP432P401R
Other Parts Discussed in Thread: MSP-FET

Tool/software: Code Composer Studio

I would like to lock the JTAG/SWD on my MSP432. I am using an MSP-FET-432ADPTR with an MSP-FET to program the chip. I wanted to first make sure I could do a factory reset before I locked the port. Following SLAU575B section 8 to try the factory reset, whenever I right click on the CPU and click show all cores, the DAP doesn't show up to allow me to do a factory reset. I have the target configured for TI MSP430 USB 1.

If I plug into my MSP432 launchpad (and change the target configuration to XDS110) then the DAP shows up and I can do a factory reset.

Is it possible to factory reset using the MSP-FET and adapter board? If not, how else can I perform it on a custom PCB, so that I can safely lock my JTAG?

Thanks a bunch!

    Yes it is possible, please take a look at this post:

    e2e.ti.com/.../2023651

    But for this particular use case (when you disabled the JTAG/SWD interface) the msp-fet won't be able to run the Factory Reset. I'm discussing this internally with the tools team  to understand the reason behind it.

    Just to be clear the XDS110 should do the trick. Now if you do not have a XDS110, you can use the BSL with the msp-fet (UART interface) or MSP-BSL (Rocket) and the bsl scripter. Please take a look at this document.

    Feel free to let me know if you need any help using the BSL.

      Hopefully this helps.

    Hello Cody,

     Quick update. Starting from CCS v7.1.x you should be able to use msp-fet to run the factory reset. The flow is not the same as the XDS. 

    1. Assuming that your device was locked. Launch your CCS project with the msp-fet (please make sure that this option is NOT selected on your debug properties)

    2. You will something like this:

    And pressing the Factory Reset should do the trick.

    Hopefully this helps.
