I have a nrf51822 project with S110 (v6.0.0) softdevice. I am using latest sdk (v5.1.0). I compile the project successfully with gcc and it does run too. But I struggle with lack of RAM for further development and I see that there is huge portion of ram taken away by impure_data. Googling will tell me that it is possible to get rid of it but it is not an easy task. Also I know that with usage of printf & co, it will be taken in. Does anybody have an idea how to get rid of it?
