Using Kickstart with MSP430-169STK and MSP430-JTAG:
I think this fixed the problem - in either case, before this I got a debug error “Security fuse blown”. After doing this, I am able to download and debug code.
In IAR under [Project][Options…][Debugger][FET Debugger] Check “Attach to running target” and make sure the Connection section specifies LPT1 (or whatever is appropriate for your env). Then uncheck “Attach to running target” for normal debug and download (verify Connection is again LPT1 or whatever you need).
NOTE - For this board, in the sample flasher application, change the #include to msp430x16x.h, and change the I/O to port 3, bits 6(RED) and 7(GREEN).
