MSP430 Spy Bi Wire Connection Problem

Other Parts Discussed in Thread: MSP430F5529

Hi,

Currently, I am trying to download code into MSP430f6779ipz microcontroller through MSP-EXP430G2 launch pad by SBW. However, the IAR workbench pops up error saying "cannot find device" when I click the download button. I have also successfully downloaded the code into the original chip on the launchpad, so I think there is no compatibility problem between the software and the launchpad. The connection that I have followed is included in the link below.

I need to finish this within a week, so I am in a hurry. Thank you for your help!

    Most probably id does not find any known device. In section 4.7 of the Launchpad User's Guide you can find a table listing supported devices. Make sure your's is listed. If not - you need another programmer like  MSP-FET430UIF

    MSP430G2xx LP can flash MSP430x2xx devices. Unofficially, it is also able to flash some MSP430F5xx and others. MSP430F6679 is new chip, that is not supported by MSP430G2xx LP firmware. MSP430F5529 LP is the new one, that support almost all MSP430 devices, but can't confirm that is working with MSP430F6679 without trying first.

    Anyway, it must be able to update MSP430F6679 flash with built in UART BSL, maybe with MSP430G2xx based BSL (slaa535 LaunchPad-Based MSP430 UART BSL Interface).

    Thank you for your reply! I will definitely try the launchpad you have suggested. However, I have used only 4 wires for SBW ( one for ground and one for AVCC and DVCC). I just noticed that there are VDSYS and VASYS pins which should be used to control the power source. May this be the problem? If yes, could you please kindly help me on how to connect VDSYS and VASYS pins externally? Again, I really appreciate your help!
