Try adding -msoft-float

Hi slawcus,

Tried -msoft-float already, but it does not work :( It produces error: ...libc.a uses Hardware FP, whereas Hello.elf uses Software FP. Once again, I feel that Cortex-M3 does not have hardware FP, but the gcc library is built using hardware FP option. So can't use this library for Cortex-M3. Question is how / where to get library built with sofware FP (suitable for Cortex-M3) ? Regards, Pramod

Hi,

Thanks to Jeff, (

http://sourceware.org/ml/newlib/2009/msg00073.html

) I found that I am using wrong library version. I changed it to another version found under sub-directory thumb/thumb2 and then it works fine! I did not have to ''build'' any new library. It already had many different versions, built using different options. Only I was using wrong version. Thank you all for your help. Regards, Pramod
