Hi Viktor, first a disclaimer:
It is a lot of time that I don't work with msp430 silicon, so my knowledge it is not up to date, so please take this a a starting point: I think a RIOT msp430 maintainer could make a more clean and polite job than me, and I think it would be a GREAT thing. Now some info and a recipe to try get a working RIOT port to "the new" msp-elf-gcc. I have arranged a build for chronos board with the fork: https://github.com/attdona/RIOT (some minor patches about removing duplicated types definition and the new msp430 gcc ISR syntax) and with the following compiler version (not mandatory, just for reference): msp430-elf-gcc -v Using built-in specs. COLLECT_GCC=msp430-elf-gcc COLLECT_LTO_WRAPPER=/usr/local/gcc-msp430-elf-dev-20141215/libexec/gcc/msp430-elf/5.0.0/lto-wrapper Target: msp430-elf Configured with: /home/attilio/MIOT/gcc_repo/gcc/configure --prefix=/usr/local/gcc-msp430-elf-dev-20141215 --target=msp430-elf --with-newlib --enable-languages=c Thread model: single gcc version 5.0.0 20141105 (experimental) (GCC) The ugly part it is that I needed to patch the compiler !!! You will find the instructions into cpu/msp430-common/gcc-patch/README.md I've just verified that the platform build successfully but I have not tested the fw. Let me know if it works for you. ciao Attilio On Thu, Oct 29, 2015 at 7:35 PM, Viktor Váczi <viktor.vaczi...@gmail.com> wrote: > Hi! > I try to port riot to CC430F5137 using a panstamp board ( > http://www.panstamp.com/product/197/ ).
