MSP430FR2433: Program MSP430FR2433 LaunchPad with MSP-FET

Part Number: MSP430FR2433
Other Parts Discussed in Thread: MSP-FET

Tool/software:

How do I program the MSP430FR2433 LaunchPad using the MSP-FET?

I would prefer to use the 2-wire JTAG.

What connections do I need to make between the MSP-FET and the MSP430FR2433 LaunchPad?

What do I need to do in CCS to be able to flash the device?

    Hello Michael,

    Follow the 2-wire JTAG connections guide from the MSP430 Hardware Tools User's Guide and seen below.  Use TDO/TDI and TCK, as well as power and GND. You can connect them to the Launchpad programming headers.   

    As for CCS, I believe it automatically tries both JTAG and SBW when attempting to connect so I don't believe there is anything you need to do there.  

      

    Thanks,

    JD

    Hi JD,

    I tried that, and I got the "Error connecting to target: Unknown device".

    I believe R1 is already on the board, so there's no need for a separate pull-up resistor, right?

    Hey Michael,

    R1 and C1 should already be on the launchpad, so you shouldn't need external components.  I would double how you are powering the MCU.  Also make sure you are using the headers closest to the MSP430 and not on the programmer side.  

    You can share a picture of your setup for review if you'd like. 

    Also, I'm not sure why you are wanting to use the MSP-FET specifically, but you can also use the eZ-FET from another Launchpad if you have one handy. 

    Thanks,

    JD

    Hi JD,

    I got it working. 

    I had the wrong end of the MSP-FET JTAG cable plugged in.

    It flips pin 1 if you do that, so as a result, I did not have the proper TDO/TDI and TCK connections.
