MSP-FET430U64F: MSP430 FET Flash Programmer

Part Number: MSP-FET430U64F
Other Parts Discussed in Thread: MSP430G2553, MSP-FET

Tool/software:

Hello Team,

I have a MSP430 FET flash programmer and a custom board with MSP430G2553 MCU. But when we tried to flash MSP430G2553 with FET Flash programmer, it is failing. But if we tried flashing MSP430G2553 with MSP-EXP430G2 by connecting RST,TEST and GND pins between, we are able to flash the binary. Kindly let me know that if we can connect RST, TEST, GND pins from MSP FET flash programmer and flash MSP430G2553 MCU?

Added schematic for your reference. Thank you

    Hello, 

    Do you have a programming header somewhere?  How are you connecting the MSP-FET?  

    Using a launchpad to program is totally fine, but you should be able to program via SBW with the MSP-FET as well.  Usually, the MSP-FET isn't wired up pin by pin but is plugged into an on board programming header, which I don't see in the provided schematic.  

    It seems like an MSP-FET wiring issue more than a board issue, since it can be programmed from a launchpad.  

    Thanks,

    JD

    Hello JD,

    Thank you for your response

    We are not using any programming headers in the board. But we have a on board pins header with RST, TEST and GND pins. 

    My question is that by connecting only RST, TEST and GND pins to the MSP-FET flasher and is it possible to flash binary to MSP430G2553. 

    Thanks,

    Vinay

    Hey Vinay,

    Figure 2.2 of the MSP430 Hardware Tool's user guide shows the recommended programming connections for 2 wire SBW programming of MSP430G2xx devices.  

    I would say that at a minimum, you would need SBWTCK (TEST), SBWTDIO (/RST), GND, and VDD connected.  VDD can either be supplied by the programmer or supplied on the board, but the MSP430 will need to be power to be programmed.  

    TEST/VPP connection that you see here is used for physically blowing the JTAG security fuse, so that's only necessary if you are trying to do that. 

    Thanks,

    JD
