Hi guys.

I apologize if answer for this questions seems obvious to some peoples, I'm quite new to this.
I can't figure out what is the name of a target for barebone arm cortex-m3 cpu - I have tried some combinations but calling a dummy function from library created by that toolchain caused immediate hard fault.

Possibly a tad late with this answer but I do STM32 with arm-none-eabi.

I'm working with NXP LPC family and successfully used it with: arm-bare_newlib_cortex_m3_nommu-eabi, and also (as billium noted) with arm-none-eabi.

Hey, sorry for late response.
arm-none-eabi worked :) apparently I was missing -mthumb switch. So thanks for that.

Can You give me some hints how to build an autotools library project, for example libpng?
Should I use portage in conjunction with crossdev toolchain for this or just setup relevant environment variables?
My target is barebone STM32 m3.
