STM32CubeMX is a cool little code generation tool from STM that helps you choose the pinout for you microcontroller project given the pin assignment constraints of a given CPU. The only problem is that it doesn't allow you to generate a Makefile project for use with the arm-none-eabi- toolchain.
I'll show you how to do this.
If you've never used STM32CubeMX before, checkout this great overview video first:
By the way, STM32CubeMX now runs on Mac OSX.
Configure the project pinout as you wish and then choose Project -> Generate Code.
When choosing the export properties, make sure to choose SW4STM32 as your Toolchain / IDE.
If you get any warnings, go back and fix your configuration, then continue.
Now you can import the project into System Workbench for STM32 (or SW4STM32).
Then import it as a normal Eclipse project.
The problem with this for me is that I can't (or don't know how) to hook up my Segger J-link debugger to this version of Eclipse. I tried to install the gnuarmeclipse plugin, but it wasn't working for me.
So instead of figuring this out, I made a makefile for the project, so I can import it into a normal version of eclipse with the gnuarmeclipse plugin already installed.
git clone https://github.com/SL-RU/CubeMX2Makefile.git somewhere and cd into the cloned repo.
Then run, where ../usb is the path to your exported project
python CubeMX2Makefile.py ../usb
Now the Makefile is in the root of your project and a normal make or make clean will work great!
Import it into your normal Eclipse as a new Makefile project
