Hello all, I noticed that there is a great tutorial for the STM32F0Discovery Board Development Environment Setup (Code Sourcery + Eclipse + OpenOCD) For the Linux OS on this forum. I have a similar tutorial (ARM-GCC + Eclipse + OpenOCD 0.6.0) for MS Windows 7 for those that do not have a Linux box. The tutorial can be found at www.hertaville.com.
I also have some interesting information on the GCC build process and on using the GPIO for the STM32F0 Microcontroller.
I hope that you find the tutorial to be helpful and appreciate your feedback.
