Many of you should be aware of the capability that eclipse provides in terms of SW development! We were successfully able to first compile code with ARMGCC and then integrate the setup with Eclipse. Now that makes a great combination for bare metal development. Check out the tutorials with links below:

This has been tested on a windows machine, we will test on a linux and ubuntu soon. If anyone wants to help us out with, do sign up the beta testing program (link in the project description).

We have also been working on CMSIS DAP(Debug Adapter) interface that has SWD pins. The hardware will work with OpenOCD, the plan is then to integrate OpenOCD and make it a completely free and open source tool chain.
