MSP-GANG Problemmer can't program msp430Gxxx

Other Parts Discussed in Thread: MSP-GANG, MSP430G2303

Hi everyone:

I am using msp-gang to program the mcu.

When I program msp430F2312, it's successful for everything, erase, blank check and program.

But when I program for msp403g2303, it can be erase, blank check but can't be programmed.

Error message shows that when it's program from address F000--F440, nothing happen, everything is ok, but next address, the device report me as below

ERROR 33: IR Interrupted  
Failed
ERROR 33: IR Interrupted 

SBW is different between MSP430F2312 and MSP430G2303? I have no idea about it.

So is anyone can help me to resolve this problem?

    SBW is the same on MSP430F2xx and MSP430G2xx devices, because it will not be possible to flash together / in parallel, MSP430G2xx and MSP430F2xx devices with my MSP-GANG like SBW+ flasher.

    Maybe your MSP430x2xx target boards are different (or something on TEST / RESET line). Or maybe MSP-GANG firmware is too old.

    Thanks for your reply

    Your point:

    My answer:

    I have run successfully on erase, blank check, and I can program from F000->F440, but fail atter that.

    so , I think maybe the chip is down? or is there any different SBW circuit between msp430Fxxx and MSPF430Gxxx?

    I have cut some components from it,  just a 47K resistor, but no10uF and 0.1 uF capacitors, 330 resistor.

    Although just a 47K resistor  on the circuit, MSP420Fxxx can be downloaded successful. According to this, I layout the same circuit on MSP430Gxxx board. Maybe this is the root cause?


    Is there any other good idea?

    And what happen if you try to flash from F800h-FFFFh, not from F000h

    47K / 1nF combination on RESET pin should be fine.

    I have MSP430x2xx target board wit DIP socket, and it is working OK (SBW flashing), without any difference if in socket is MSP430F2xx or MSP430G2xx device. And deeply doubt that your MSP430G2xx target chip is damaged.

    So thanks!

    I will add 2.2 nF capacitor (is it right ? not 1nF , OK?) to the circuit, if still fail, maybe the chip is damaged!!!

    What MSP-GANG firmware version are you using? (Go to About > About and take a screenshot or report the firmware version used). If you aren't already, I would recommend using the latest MSP-GANG software version (1.1.7.0 at time of this post). http://software-dl.ti.com/msp430/msp430_public_sw/mcu/msp430/MSP_GANG/latest/index_FDS.html

    Can you post a screenshot of your MSP-GANG settings, like your memory settings and the settings in the GUI main screen?

    Could you provide more information about your connections between the MSP430 and MSP-GANG - are you trying to power your board from the MSP-GANG, or power it externally for example? A picture of the SBW connections on your schematic might be helpful.

    Regards,

    Katie
