Hi,
We have looked into the new TI MSP430 toolchain. Although it is based on the newer tools, it currently contains one major bug: if you use the -ffunction-sections flag that helps removing unused code from your binary, the debug symbols become unusable.
We have repackaged the toolchain (without TI proprietary tools) and uploaded it together with a one-click installer here: http://gnutoolchains.com/msp430/
Remember to remove the -ffunction-sections flag from the debug configuration flags, as otherwise you won’t be able to debug your code.
