RE: [arm-gnu] C run-time initialization code

I’m looking for the c-runtime initialization.  The code clears the .bss and
that copies initialization values from rom to .data and then calls main.  On
the M3, it generally also has the exception/interrupt vectors.

Thanks,
Richard

Could you expand a little on what startup code you're looking for?
Judging from the names, it sounds like you might be talking about CMSIS.
