Compiling ARM in Windows with Eclipse - c

Question

I would like to make C program for the cortex - M0 processor. I work with 64-bit window machine and Eclipse. I found many things on internet and I am confused:
1.MinGW
2.ARM GCC compiler for windows (which can be set in the advanced system in computer, the PATH variable)
3. ARM GNU compiler from Eclipse market
Among all this , Which compiler can be used for ARM and can I output my results on command line. i.e Can I compile the program and produce results on the console ?
This result below is what I get when I try to compile a hello program using the command: arm-none-eabi-gcc -o -tesres -test.c

Answer 1

You can use the ARM GNU compiler from Eclipse marketplace. When this is installed, you can Create a new C/C++ project with the correct Project type -
e.g. Executable/STM32F0xx C/C++ project if that's the series of chip you wish to target. Make sure Trace output in the wizard is NOT set to None (no trace output). You can then use trace_printf to write to host console via ST-LINK, as the hello-world example will show.
You may also have to install and configure OpenOCD to capture that output and display it in Eclipse's console. In Eclipse, you just set up an external tool Run > External tools > External tools configuration. Specify the location of openocd.exe, set the working directory and, in Arguments, specify which devkit you're using by using the appropriate config file, e.g. -f board\stm32f072discovery.cfg.
Then build, run OpenOCD and debug.

Under Windows for M0 I've been using IAR Embedded Workbench, which was a nice and smooth experience for me. But as far as I remember it needed a license.

Maybe you should look for free options in this list.
