This command line isn't correct. Should contain flags: -mthumb -mcpu=cortex-m3 (if you are using gcc-4.6 or newer you can also put -mcpu=cortex-m4) Recommended: -O2 I recommend you, as a template, to use the Makefile provided with examples. I hope this helps. Ilija -- Before posting, please read the FAQ: http://ecos.sourceware.org/fom/ecos and search the list archive: http://ecos.sourceware.org/ml/ecos-discuss
