Hi Matthias,
Thats awesome! I am about to push the new tools up to the Energia repository
and have one question before I do so.
msp430-gcc -v reports:
gcc version 4.6.3 20120301 (mspgcc LTS 20120406 patched to 20120502) (GCC)
Shouldn't that be "patched to 20120911". I don't care about the version number
but do care about the 9/11 FRAM patch and want to make sure it is in before I
release Energia to the masses.
Thanks,
Robert
