MSP430's do not support boundary scan
Well, they do, but TI does not provide its customers with complete BSDL
files for these devices. Having NDA access to the JTAG information, I
think there are valid reasons for this. Opinions may vary (don't they
always :-) ).

I cannot find them on the TI website. Without these, you cannot
access pins
around the device to perform boundary scan testing, since you have no
idea about
what pins you may be accessing. (Perhaps they do not support boundary
scan,
however, that is why JTAG came into existence (At least, I though
this was why!)
It only appears that TI describe some of the JTAG states that will
allow access
to various parts of the device internals, useful for programming and
debugging.(see http://www-s.ti.com/sc/psheets/slaa149/slaa149.pdf)
The development of gdbproxy required an NDA to get information about a
greater range of facilities accessible through the JTAG interface. They
reveal apsects of the chip's operation which TI do not wish to make
public. I believe this is why BSDL files are not provided.
