I'm a bit late here but just as a heads up ARM have an officially developed Cortex-M* GCC target which hosts just fine on Linux: https://launchpad.net/gcc-arm-embedded https://launchpad.net/gcc-arm-embedded With OpenOCD and STLink the STM32 family of Cortex processors are easy to use with Linux (arguably easier than in Windows, actually, because the toolchain isn't as shitty). I do agree that using them from Windows in the often-documented "beginner's path" way really sucks.
