There isn't anything further to add here. So it's really worth the work of a couple of days or more to get there. I'm steaming ahead now and I'm really appreciating the switch to Eclipse. I used the Nordic guide and some trial and error once installed, and got it up and running in a day or two I think all included. I've actually tried to setup Eclipse and GNU like a year ago, but it was so difficult compared to Keil that I gave up on it. Apparently the sections were not what Keil expected, and to be honest, at this time I was pretty tired of Keil. Finally I switched Keil to use the GNU toolchain, and after a long struggle again changing all my code to get it to work and compile with the GCC compiler, I finally got a binary. I had many problems with straight forward things that it wasn't able to compile, and I struggled with many simple thing for days. I've used Keil to begin with, and it works very well out of the box. Most applications will actually fit inside 32k because of the architecture and SDK that Nordic provides. The SoftDevice stack is precompiled so it does not count into the 32k limit of the free version of Keil. I am starting my development work with Nordic Semiconductor nRF Device and already purchased the Development kit.
