Hi,
The ARM-USB-TINY-H says it works with MSP430. Is there some documentation that I can find to program MSP430 via JTAG using ARM-USB-TINY-H? Is there some documentation on how to support MSP430? I can add support to MSPDebug to include ARM-USB-TINY-H.
No documentation at all.
I believe that the FTDI2232H chip inside is good enough for BSL programming but I don't know if regular JTAG is achievable. In any case it would be significant software effort.
If you need more info maybe check on using "FTDI to program MSP430". You get results like this:

Maybe ask again in TI forums or OpenOCD forums, somebody might have done something in the past.
