Using CCS 5.1 with an MSP-FET430UIF. We have a target device with Vcc, TCK, GND, and TDO coming off of it and I'm running those into the debugger using the pins called out in the hardware tools guide. Every time I try to connect, I'm getting the error: "Error connecting to the target: Unknown Device". This sounds very similar to the problem in http://e2e.ti.com/support/microcontrollers/msp43016-bit_ultra-low_power_mcus/f/166/t/37302.aspx, where the device actually was not supported.
We're using an MSP430G2553.
Does anyone have any ideas about this?
If you're using the two-wire SBW interface, then you need to connect TEST/SBWTCK as well as RST/NMI/SBWTDIO which are the ports for Spy-by-Wire.
The G2553 also supports normal JTAG, so if you don't mind the extra pin counts that should work also for the FET430UIF.
Hi Joshua, is your device connected as from page 26 of hardware guide?
If so try reduce or completely remove reset capacitor and see if connection appear, again try a power cycle and if always not recognized ask again specifying how device is powered and how power sense pin are attached to UIF.

Apparently we forgot the pullup on our proto-board, so I was able to get this working with some help from our local FAE. All set and working now! I appreciate the assistance.
