Hi!
I have an application running on F1101a which I want to migrate to F2001 (I don't use all the I/Os and the lack of POR reset in F1101a is not a feature that I like).
Now, I did all my firmware development under open source tools using mspgcc and their python driven tools to program MSP430 parts (I've used both the JTAG and the BSL). It was especially convenient for me since I'm using mainly FreeBSD on my computers and all the mspgcc stuff can be compiled on FreeBSD w/o problems. I used MSP-FET430 as hardware to connect to the JTAG interface.
I have this F2001 parts and I would like to program them. What are my options if I want to continue to use mspgcc tool suite: a) can MSP-FET430 drive the 2 lines required by SpyByWire? if not b) can a ez430 be used under FreeBSD or Linux?
My understanding is SpyByWire is just a JTAG time multiplexed on 2 wires. Could a parallel port drive that or ez430 is a must?
I understand there are some IP issues related to the JTAG protocol but those are mainly for the debugger and not for the programmer. [As a side note I've asked some while ago for a msp430-gdbproxy compiled for FreeBSD with no result/reply].
Thanks for your time!
