I just noticed that the tool chain I'm using (arm-none-eabi from Codesourcery, version 4.6.3), does not seem to know what to do if I specify the M0 core to the compiler.
Does anyone in the collected group know if setting the processor to M3 works? Or is there some magic instruction that may get invoked and mess me up?
Alternately, since that tool set version is dated from March of 2012, does anyone know if the up-to-date version has explicit M0 support?
Thanks.
