The latest uniarch msp430-gcc does support the msp430fr5739. However, at this time, mspdebug
doesn't support it. I have exchanged emails with Daniel Beer, primary developer on mspdebug,
and he has indicated he is already working on this. I'm hoping this welcome addition will appear soon.
There might be another option. I just noticed that TI offers a command line win32 only program flasher
with source code on the their website:
It might be possible to run this using WINE under linux. I haven't even tried this on Windows so I don't
know if the program even supports the FRAM chip.
BTW: msp430-gcc uniarch just got easier to install on ubuntu. You can now find the required binary
install packages at https://launchpad.net/ubuntu/oneiric/+search?text=msp430. Previously, I was using
a source build I hand cobbled, now I've switched to binary install with good success.
Note: I'm running Ubuntu 11.04 natty.
Once the new version of mspdebug comes out with support for the MSP430FR5739 chip
which is in the FRAM experimenter board, you are going to want something more than just
a blinky program to see if it works on your system.
I modified the User Experience Code Demo code for the MSP-EXP430FR5739 so that it
compiles with the latest msp430-gcc.
