Mspdebug can be used to program this device using its `eZ FET lite' interface, however, it doesn't appear to work reliably.

Mspdebug with the tilib interface does seem to work reliably, yet, if ez-fet mode was attempted before-hand the full board will need a hardware reset.

MSP430 Flasher can program this device using TI TEXT files.
