Part Number: MSP430-FLASHER
Other Parts Discussed in Thread: MSP430FR4133, MSP430FR6989, CCSTUDIO, UNIFLASH, MSP-EXP430FR6989


I am using MSP430FR6989 development board and I need to flash a source code to MSP430FR4133 chip. But MSP430 Flasher is not responding with its any of the options.

Do I need any extra hardware for flashing?

Can I flash my code with MSP430FR6989 development board?

and why MSP430 Flasher is not responding?

any help is greatly appreciated



  • Hello AGS,

    What MSP430FR6989 board are you using? I assume you are using spy bi wire for programming, correct? Do you have your own MSP430FR4133 board? If so, do you have the required resistor and cap on RST line?
  • Sir,

    I am using MSP430FR6989 LaunchPad and I don't have  MSP430FR4133 board.But  I am using a custom board with  MSP430FR4133 chip on it  and the reset line of the board have required resistor and capacitors . The following pins of LaunchPad are used to debugg the custom board with the help of Code Composer Studio .





    But I have to flash the source code to the custom board with out using CCStudio. 



  • AGS,

    Pins look correct, but 5V is a problem. The maximum supply voltage on MSP430 is typically 3.6V. Voltage above this is outside the specification and could damage the part.

    Please reduce the voltage, although I cannot say if damage is already done by applying 5V. Also, can you try flashing with Uniflash or Elprotronic Flash programmer?
  • Eddie, I'm curious why you suggested he try other programmers.  Presumably he is using the MSP-EXP430FR6989 LaunchPad Development Kit, and it seems it should be possible to flash firmware via in-circuit SBW using that Launchpad and the command line  MS430 Flasher, assuming the connections are right.  Is that correct?

    One thing to check:  I think this chip has a JTAG protection lock somewhere (maybe 0xFF80) that has to be FFFF or 0000 to be unlocked.

  • George,

    I agree that the MSP Flasher should be able to successfully program the device. I just wanted to give another option in case something is incorrect with the MSP Flasher set up.

    Good point about checking the JTAG protection lock.
  • Hi,

    We have voltage regulator on our custom board which give 3V output.So connecting to 5V is not a problem. Also the problem is fixed and  now we are able to flash the code as we expected .

    Thank you all for your support and concern.

    with regards ;
