Is it possible to program an MSP430F123 via SPW on the LaunchPad, or do I need to get a proper JTAG programmer for this?
I have an F123 in a SOIC28 package on a breakout board I designed, and I'm bringing the TEST, RST, VCC and GND lines out to the LaunchPad. This configuration has always worked for me with MSP430x2xx family chips such as the MSP430G2252, but it's not working for me with the F123...CCS 5.1 claims that it couldn't connect to the target.
I noticed the documentation for the MSP430x1xx series doesn't mention anything about a Spy-Bi-Wire functions on the TEST and RST pins (a detail I overlooked when making my breakout board), but I'm not sure I'm reading it right, because the datasheets seem to hardly mention SPW even when it *is* supported.

Thanks, =hat explains why my programming doesn't work.
Can you recommend a piece of hardware for full 4-wire JTAG programming?
In reply to Andrew Villeneuve:
If you want to spend the money, use a MSP-FET430UIF for example. It can be found in the TI eStore:
It supports all MSP430 flash devices, regardless of SBW or JTAG. Also many development board from TI have a matching 14pin connector for this kind of pod.
