On board programming

Other Parts Discussed in Thread: MSP-TS430PW28A, MSP430G2553

So for a class I have to design a circuit board where the MSP430G2553 will be surface mounted. I have the MSP-FET430U28A programming kit. The problem is that I need to be able to program the MSP430G2553 while it is on the circuit board that I am designing. In summary I need to recreate the circuit from the 14 pin serial on the development board to the actual chip. I have found the actual schematic for the development board MSP-TS430PW28A, I am not 100% sure on which connections I need to make. I will have a separate power supply so no power will be needed from the development board. From what I gather I need to connect pins 1,3,5,7 on the 14 pin serial cord to pins 1.7,1.6,1.5,1.4 respectively. Any help is much appreciated...

For refrence http://www.ti.com/tool/msp-ts430pw28a.. and download the technical documents the schematic is located in there...

Thanks

    The FET of this kit is designed to program all MSPs in-circuit. You only have to provide the proper connector.

    If you don't have the space for the 14pin connector (see the schematics of the board to see how it is connected), you can strip It down to 4 pins (GND, VSense, RST/SBWTCK, TEST/SBWTDIO). You can then do only SBW programming, which is slower and sensitive to the wiring between MSP and FET (especially capacitance!), but 4 pins are smaller than 14 :)

    You'll find threads with additional information in this forum if you search for JTAG. There's also an appnote about JTAG programming. And the FET is explained (with schematics) in the MSP430 hardware tools users guide.

    Customers I've worked with have placed on the board a very small pitch connector with 14 pins and created an adapter board to convert between the 2.54mm pitch of the JTAG and the pitch of the connector.

    Spy-Bi-Wire is an option, but it will mean slower programming.

    10 pin mini-jtag is an option

    All he would need is:
    TDO
    TDI
    TMS
    TCK
    RST/NMI
    GND

    Optionally for powering target you can have VCC from the FET
